​Whelp, summer’s over. Sorry to be the bearer of bad news, but hey… there’s always next year! So, along with football season and colorful fall foliage comes the return of colder weather. As we’ve discussed before (Strait Talk, February 2015), this is the time of year when your HVLS fans really start returning on their investment by lowering heating costs. But don’t be like all those other jabronis that continue to spin their fans in reverse. Why? Let’s discuss further!
 
As we learned all the way back in February 2015, the most efficient way to destratify air is to spin your fans slowly in the forward direction. This will mix the air vertically, giving you a warmer overall temperature profile ceiling to floor. So why not use reverse? Doesn’t it work for home ceiling fans? The answer is yes, but there’s a reason it works in a residential setting: the fan is usually much closer to walls. Also, most house fans do not have a forward setting slow enough to not create a breeze. So running them in reverse not only mixes the air, it keeps those in the room from getting chilly.
 
The same is not true in a warehouse or other industrial setting. Since HVLS fans are best used in large, open areas, they are generally not near walls. Because of this, running them in reverse results in lower air mixing efficiency, and can increase the time needed to equalize the floor to ceiling temperature. Proper destratification involves spinning your fans in the forward direction at a speed fast enough to move air, but slow enough that it does not create a discernible breeze.

So what’s the moral of the story? You never need to use the reverse direction on your fans – just vary your speeds from season to season. Turn them up in the summer to create a cooling breeze, and dial them back in the winter to destratify. Seriously… how easy is that?!

*Actual savings depend on heating costs, size of facility, number of fans, and other factors.

With businesses opening back up, cleanliness doesn’t only apply to the health of employees, it also applies to the health and performance of your Patterson high velocity fans! While built to last in the most rugged conditions, cleaning your fans regularly can add years to their life, cut down on replacement costs, and even save you money on energy consumption. Here’s why:

Over time, dirt will begin to build up on two major areas: the guard behind the motor and the fan blade itself. If left untreated, this can lead to a number of issues. First, a fan guard caked with dirt will not allow proper airflow over the motor, causing it to heat up as well as increase its amp draw. Higher amp draws mean greater energy consumption, which in turn leads to higher electric bills… And no sane person wants that.

Dirt on the fan blade can be equally as troubling. Since the motor and blade are designed to function as one unit, any sort of buildup can cause an imbalance in the blade’s rotation. This can place constant stress on the rotor (due to fan blade “wobble”), and in some cases cause a fatigue crack on a blade paddle.

So, as we prepare for another hot summer, be sure to take a moment to clean your Patterson high velocity fans. Your maintenance budget will thank you!
​
Steps to create a clean, healthy, and productive fan:

• Remove fan guard.
• Clean the fan of all dust, dirt, and grease.
• Replace and enjoy!

It’s that wonderful time of year when we transition to cooler mornings with much warmer daytime temperatures. Often this leads to unwanted moisture, both in the air and on the floor. How do we deal with trying times like these?! Why, with fans of course! Curious? Read on, gentle patron!
 
Control Moisture: Keep Your Facility Dry
 
Ever heard the term “sweating slab syndrome?” This is caused when a cool concrete surface meets warm, humid air, resulting in condensation (much like a glass of ice water on a hot summer day). Wet concrete is a major slip and fall hazard for both workers and forklifts. Continuous use of high velocity and HVLS fans will increase the evaporation rate, allowing surfaces to dry quickly (in some cases, it may prevent the moisture altogether).
 
Control Humidity: Keep Your Ceiling-to-Floor Temperature Consistent
 
High velocity and HVLS fans can help reduce humidity by continually redistributing air and, in turn, evaporating the moisture caught in the air. Protect machinery, product, and the building from corrosion by strategically placing fans throughout the facility. Keep the air moving and the humidity in check!

Everyone seems to be obsessed with using less these days, an altruistic endeavor they call “going green” or “reducing your carbon footprint.” To that end, energy consumption has been placed squarely in the crosshairs. But wait… I still need to stay cool in the summertime! Is there any way I can keep cool, go green, and reduce my carbon footprint? Why yes… yes there is. It’s called evaporative roof cooling, and I implore you to read on…

An evaporative roof spray system intermittently sprays a thin film of water on the roof surface, and then allows the water to evaporate. When performed in regular cycles, this prevents the roof from getting hot and transferring that heat into the building. Since 50% of the heat load inside a building comes from the roof, the result is lower interior air temperatures. For air-conditioned facilities, evaporative roof cooling can also reduce the load on the HVAC system, producing immediate energy savings.

Looking for alternative ways to stay cool this summer? Interested in evaporative cooling? Have lots of questions? Great! We're here to help you figure it out! With over 40 years of expertise, we can design a system that fits seamlessly on your roof – providing hassle-free cooling for years to come!

We hope you're reinvigorated and getting started on planning your year, or if you're really good, you’ve already started on projects! The beginning of the year is also a perfect time to evaluate your ventilation needs. You may already have a list of what must be replaced, added, or upgraded, and are already deciding project timelines and goals. This is good! If not, you may need a bit of help figuring out the right amount of fresh air to get moving through your facility so you know what products to get. This is where we can help. It’s vital to your employees’ safety, comfort, and productivity to get the bad air out and the fresh air in.    
 
So, how do you accurately calculate your ventilation needs? It starts by determining the rate at which you need to completely replenish the volume of air in a given room. This is known as an air turnover (or air change) rate and is usually expressed as number of air changes per hour (although it can sometimes be seen as “minutes per air change”). The number of air changes needed ultimately depends on the type of facility or the work being done in a particular area.  For example, a typical warehouse should change air approximately 12 times an hour, though this can vary between 6 and 30.  By contrast, a garage needs to replenish its air 20 times in an hour to protect employees against heat buildup and noxious fumes.
 
Once the air change rate is determined, we can proceed with our calculation. For purposes of this article, we’ll make the math easy (because… hey… who doesn’t love easy math?!). Let’s say you have a 100’ x 100’ building with a 25’ ceiling height.  Based on the work being done, we’ve decided on 12 air changes every hour. Your calculation would look like this:
 
100’ x 100’ x 25’     =      250,000 ft³ 
                                              60/12         =    50,000 CFM
 
Based on our calculation above, you would need to move 50,000 cubic feet of air per minute (CFM) through your facility in order to achieve 12 complete air changes an hour.
 
Being responsible for ventilation in your facility doesn’t have to be difficult. So now that you know your ventilation needs, what’s next? Why not call Patterson?! We have the people, the products, and the knowledge to help you build the ventilation system of your dreams! And be sure to check out our new ventilation brochure. It’s packed full of product specs, proper placement suggestions, and more!

Have you ever agonized over the purchase of a new A/C system at home?  Perhaps more energy efficient windows or better insulation?  Usually, the first question you ask (after, of course, “that’s going to cost HOW much?!”) is, “how long before this pays for itself?”  When it comes to evaluating potential capital expenditure projects (whether at home or at work), one acronym stands above the rest – ROI, or return on investment.  If you’re considering HVLS fans for your facility, calculating ROI helps estimate the time period necessary for full payback in the form of energy savings.  But how are these calculations done, and what critical information is needed to do them?  Keep reading to find out!
 
Energy savings from HVLS fans are generally realized during the winter months, due to destratification.  Because of this, knowing your heating cost and consumption information is vitally important, as HVLS fans can help reduce them both by up to 30%!  Also important is the cost of your electricity, since heaters consume electrical power as well as natural gas when they are in use.  Other inputs that help “fine tune” your ROI calculation include:  facility square footage, hours of operation, number of heaters, heater voltage and amperage ratings, and average length of the winter heating season.
 
So how is all this data used to calculate ROI?  It all starts by estimating current resource consumption costs (both natural gas and electrical – I will spare you the boring formulas here).  Once a total consumption amount is determined, calculate a projected savings amount as a percentage of that total consumption (15-20% is usually a solid, conservative savings estimate).  Then, subtract your fan electrical costs (again, boring formula) from your savings – this is your net savings amount.  Finally, divide your net savings by the projected cost of your new fans and – Bob’s your uncle – you have ROI (in number of heating seasons)!  Pretty easy… right?!
 
Of course, as with any calculation, the result should be used as a guide toward making an informed cap-ex budget decision.  It should not be taken as “gospel,” as any number of factors can affect the actual savings amount (e.g. price of natural gas, unusually harsh or mild winters).  But overall, an HVLS ROI calculation can provide valuable insight into current resource consumption issues, and identify potential air movement solutions.

​Well, guess what?  It’s summer again.  And – lo and behold – it’s scorching hot out there.  While the extreme heat may send you running for the nearest swimming pool, it can also cause reduced productivity and dangerous medical complications in the workplace.  Let’s dive a bit deeper. (See what I did there?)

Could your facility answer ‘yes’ to any or all of the following?

• Does employee productivity decrease during the summer months when temperatures are elevated?
• Do employees complain about the lack of airflow in the workplace?
• Do processes or equipment produce heat that could be dissipated by air circulators?
• Do certain manufacturing or assembly processes create a large amount of condensation?
• Are there products or components that should be cooled after manufacturing?

So what can be done to neutralize this formidable opponent?  How about the all-important one-two punch of air movement?

ONE: VENTILATE
Moving air through supply and exhaust ventilation not only cools the workplace environment and makes it more comfortable, it also helps control airborne contaminants. Industrial ventilation can also help prevent the buildup of noxious fumes, fire, and odors. Exhausting the hot air from your facility will go a long way toward keeping the temperature, humidity, and air quality at a safe level.


TWO: CIRCULATE
Without movement, air can stratify and stagnate, creating pockets and layers of hot, humid air. In addition, heat leaves our body more quickly when a breeze is present. Fans create airflow that quickly evaporates perspiration from our skin, carrying away heat. The airflow also reduces the thickness of the hot, humid layer of insulating air that builds up around our bodies, thus improving heat dissipation. In short, fans make our natural cooling mechanisms more efficient. Use high-volume, low-speed ceiling fans and portable fans to improve air circulation and natural cooling.


So there you have it!  The one-two punch to knockout heat stress and keep your employees safe, happy, and productive this summer.  And, as always, trust Patterson to be there with the right product for every air movement application.  From ventilation to circulation, Patterson’s got you covered!

Does the thought of working in a 130°F truck trailer sound like fun? If you’re a dock door worker at a distribution center, it probably sounds like the exact OPPOSITE of fun. Fortunately, Patterson has worked to mitigate this issue with their TC (Truck Cooler) 18-inch fan and HVTC (High Velocity Truck Cooler aka “the Whistleblower”). However, a fan is only effective if it’s used properly, so let’s focus on getting the most out of your Patterson truck cooling solutions.
 
The prevailing myth amongst dock area employees is that they must point fans directly at them to receive the maximum benefit.  Sometimes they will even use pedestal cage fans to accomplish this. But doing so will only provide temporary relief when at or near the dock door opening. As the employee moves away from the door, they will begin to feel less air movement – eventually reaching an area of hot, stagnant air that remains at the front of the trailer. Working in this condition for long periods can bring about the symptoms of heat exhaustion or heat stroke if not dealt with appropriately.
 
So how can we optimize airflow? Very simply, in fact! A wall-mounted, truck cooler fan needs to be positioned in one of the upper corners at the dock door opening and aimed toward the same corner at the front of the trailer. This will allow air to reach the entire length of the trailer, with two positive effects:
 
– Evacuation of trapped hot air (in about two minutes).
– Creation of constant airflow.
 
Having this continuous movement of air will alleviate many heat stress issues and provide an overall safer work environment on even the hottest summer days.

Check the calendar.  Guess what?  It’s June.  What does that mean?  It’s going to get hot very soon (if it hasn’t already).  What else does it mean?  You’re going to want fans for your facility – lots of them – quickly.  Not only do you need them fast, you need them mounted and installed fast, too.  Well, we here at Strait Talk (and, yes, Patterson too) also have these goals, and we want to help you avoid any “hiccups” in the process.  So, whether it’s placing an order or tightening the last bolt, here are some tips to “breeze” through your Patterson experience!

• What is your application?  Are you trying to move air down aisles, pick modules, mezzanines, or in trailers?  Then take a look at Patterson’s line of high velocity fans or the new db.  Open areas?  Think about the High-5 HVLS ceiling fan.  Small area cooling?  Patterson’s Fabric Air Ducts, Drum Fans, Cage Fans, and Evaporative Spot Coolers will do the job.

• Know your electrical source.  Is it single phase or three phase power?  277 Volt?  Ordering the right motor type will save time, money, and the hassle of returns/reshipments.
• Will your desired fan fit in the designated area?  If you’re not sure, take some measurements and give your Patterson sales rep a call to discuss.  That’s what they’re here for!
• So your fans have arrived….great!  Now what?  Well, as a wise man (my father) once said, “When all else fails, read the instructions.”  Take a few minutes to familiarize yourself with any installation instructions that came with your fan or fan mount.  If you ordered a High-5, pay special attention to the section on wiring the fan’s variable frequency drive (VFD).  Doing this may help answer some questions, and/or prevent any confusion for you (or your installer) during the setup process. 
• IMPORTANT!  All Patterson fans, regardless of type, come with a wiring schematic (usually printed on the nameplate of the motor).  Be sure to wire your fans exactly as shown.  In the case of a dual voltage motor, take care to select the correct wiring configuration based on your voltage level (usually 208-230 V or 460 V 3-phase service).  Have electrical questions?  Call before you connect – improper wiring can damage motors/VFDs and affect warranty coverage!
• ALSO IMPORTANT!  ALWAYS install all safe guards that come with your fan and/or mount.  They are designed to protect you, your personnel, and your facility in the unlikely event of a failure. 

So there you have it – some simple tips to make your fan buying experience smooth as silk from start to finish.  And as always, Patterson sales reps are standing by ready to dispense timely fan advice and provide free quotes for all your fan needs.

Until next time, let’s keep ‘em cool out there!

We all love to have our cake and eat it, too.  But, as anyone in a successful marriage will tell you, life is about compromise.  (Seriously ladies, you can’t have it YOUR way EVERY time!)  In the air movement business, a trade-off exists when evaluating a fan’s performance versus the noise level it produces.  So how much noise is too much?  When is it ok to use a quieter, lower performance fan?  How do you strike the perfect balance between necessary air flow and acceptable sound levels?  Answers forthcoming!
 
Before we go much further, let’s talk about the different fan types.  High velocity (HV) fans are generally considered high performance – designed to accelerate (or “throw”) air over a distance.  For HV fans, airspeed (measured in feet per minute, or FPM) is more important than volume.  However, this also translates into slightly higher noise levels, typically measured in decibels (dBA).  The other end of the performance spectrum includes cage fans and ventilation fans (think supply, exhaust, shop floor, etc.).  These fans covet volume over speed, and are usually rated in cubic feet per minute (CFM).  Are they quieter than HV fans?  Absolutely… but you won’t feel their airflow once you move more than a few feet away.
 
So which fans are right for your facility, and how should they be used?  Well… both… and it depends!  (How’s that for an answer?!)  For an effective overall air movement solution, it is best to incorporate both fan types.  For example, use large supply and exhaust fans for cross ventilation, and couple them with HV fans to accelerate air movement from one end of the building to the other.  This works particularly well if your aisle ways run parallel to the airflow.  If noise abatement is an issue (industry standard tends to put an upper limit around 80 dBA), mount HV fans well above the floor on columns or racks.  If small area “spot cooling” is needed, employ one or more shop floor or cage fans – allowing for airflow without violating any noise level requirements. 
 
So… maybe that example doesn’t fit the layout of your facility.  Perhaps you’re looking for both performance and low noise?  Great!  Give Patterson a call and learn more about their new db fan!  It offers the performance of an HV fan, with a 70% reduction in noise level!  No matter the fan type, Patterson has the products and the expertise to keep your facility cooler, safer, and more productive!  

​If you’ve been reading Strait Talk on a monthly basis (and I KNOW you have), you’ve learned that the Patterson High-5 HVLS fan is a great way to destratify heat in the winter.  But did you know you can accomplish the same goal using Patterson’s Power Tube and high velocity fans?  You didn’t?!  Well that, dear readers, is why we’re here!

Patterson has been utilizing its fan/Power Tube combination for years to deliver cooling to a large area, while using only a single fan.  But this same configuration can be used during the winter months as well.  Fan/Power Tube combos placed near the ceiling can help transfer heat from elevation back down to the working level, where it’s needed most.  The same concept can be applied to open-ended Power Tubes, which can move and distribute heat from one area of your facility to another.  This fan/Power Tube setup is a great option for smaller facilities, low ceilings, or areas that might not otherwise accommodate a much larger HVLS fan.

Whether heating or cooling, a Patterson Power Tube is an economical yet effective way to deliver employee comfort 12 months a year!  To learn more about this and other quality air movement solutions, contact your Patterson sales representative today!
