 Water
Cooled Chillers
1st Choice Chillers is a manufacturer of portable water cooled
chillers for a wide range of industries from chemical to plastic
injection molding. Our water chillers were designed to cool both
the process as well as the process machine. Using a water chiller
to remove heat from the process involves an evaporator to
remove the heat and a water cooled condenser to remove
the heat from the evaporator. In a typical plant layout, the evaporator
and condenser are inside the chiller unit while the cooling tower
is located outside. (click image to enlarge »)

Our water chiller systems generate cold water for cooling all
kinds of industrial process equipment. Choosing a water cooled chiller
rather than an air cooled unit is often a good idea unless you
don't have a cooling tower. Our water chiller systems are less
expensive than the air cooled option, they have a higher cooling
capacity per horsepower and will definitely consume less energy
per horsepower. Compared to water, air is a poor conductor of heat
making the air chiller much larger. An air chiller is less efficient
due to plant air temperatures of 95° F to 100° F during
the summer months and a condensing temperature 120° F compared
to 105° F in a water cooled chiller.
 Water
chillers often operate in the range of 15 EER or better and with
a smaller footprint, allow you to make better use of valuable plant
floor space. These are all good reasons for choosing a water chiller
except when there is no cooling tower.
Water cooled chillers require condensing water from a cooling
tower at about 85°F (29°C). If you have 85° F plant water to
use for your condenser, we offer two kinds of high efficiency water
chillers. Up to 10 ton, we use coaxial tube-in-tube condensers
and on larger units we use brazed plate condensers, with the option
of shell and tube. If you don't have a cooling tower, your only
choice is to install an air cooled chiller.
