Water Chillers

Why Buy a Water Chiller?

  • Lowers water and sewage bills.
  • Provides solid protection for processing equipment 24 hours 7 days a week.
  • Reduces the number of rejected parts, thus increasing parts produced.
  • Maintains a self sustaining source of properly chilled water.

How to Size a Water Correctly

Specify the poper chiller for your load requirements. An undersized chiller will always be a problem and will never properly cool the process equipment. Here is a a table to help calculate your load requirements.

Simple Instructions to Assure Proper Cooling
BTU=Constant (Weight of Water) x GPM x Temperature Differental
Multiply the fluid flow (GPM) by 500. Multiply the result by the temperature differential or rise (return water temperature minus the input or supply water temperature). Divide the result by 12,000 and you now have your required rating.

Example:
500
Constant (weight of water)
x10
GPM (gallons per minute
5000
 
x12
Temperature Differential (or rise)
60,000
Required BTU's per hour
12,000
EACH 12,000 BTU's rquires 1 ton of cooling
=5 Ton
(This equipment would require a 5 tons capacity)
