There are so many wonderful things about summer, except for
the heat. While temperatures outside
will be in the 90’s, temperatures inside a dry cleaning plant can reach up to
130 degrees Fahrenheit. Such heat can
lead to employee dehydration and fatigue.
To help combat that, Tri-State has come up with a
few ideas to hopefully help you and your staff beat the summer heat.
Adjusting hours
– Adjusting production times to start and end earlier in the day is by far the
cheapest alternative, provided customer needs can be met.
Cooling Systems
– There are both installed and portable cooling systems. While both are effective at cooling, they
tend to be expensive to install, run, and maintain. When it comes to installed systems, Tri-State uses MagicAire Air Handlers that have water-cooled coils in conjunction with
Kleen Rite Water Chillers to cool the coils.
MagicAire Air Handlers come in a variety of sizes, and you can purchase
the appropriately sized chiller accordingly.
When shopping for your plant, Tri-State recommends staying at or below 2
drops sized at 8” per ton of chiller for spot cooling. When piping, pipe just above the work station
so that the air comes out above the employee’s head. Portable cooling systems work well; in
essence, they are air conditioning units with a 6” hose to point at
employees. There is, however, a flaw
with this particular solution. The air
intake gets clogged with lint because many operators fail to properly clean its
filter; it is an issue that can ultimately cause damage to the unit.
Area Fans
– Area fans are an economical solution to help make the inside of a dry
cleaning plant more bearable during hot summer months. Tri-State has found that the best area fans
for use in dry cleaning plants come from Global Industrial. They can be moved around in work areas as
well as directly mounted to the wall. While
they obviously don’t cool the air, when properly placed, they do a great job at
keeping the air moving.
Swamp Coolers
– If you are in an area with relatively low humidity, a swamp cooler works well
at cooling, and it can be fairly inexpensive to install and maintain. Here’s how they work – swamp coolers are open
systems that blow air into the building drawing it through filter pads soaked
in water from an on-board tank and pump system. Unlike air conditioners, where
air passes over a set of coils filled with a refrigerant, swamp coolers cool
the air down by evaporation, and they use a lot less energy than air
conditioning units.
Ceiling Exhaust
Fans – We believe this, in conjunction with small fans blowing on
workers, is the most economical option for cooling dry cleaning plants,
provided the exhaust fans are properly positioned. Here’s a great example -- the shirt laundry
finishing area produces the most heat because of the required operating steam
pressure needed for proper finishing and production time. Placing exhaust ceiling fans above the shirt
finishing area (because they are the greatest source of heat in the building),
allows the heat to be drawn out, so it naturally cools the space. But be sure to use caution when choosing the
fan size and designing the space because you can put too much negative pressure
on the building.
