Water Chillers can save your Company lots of money-- 

• Lower your water and sewage bills
• Provides a steady thermal environment for your process

Automatic controls adjust the chilled water.
No calculations needed!

Equipment Protection
The most compelling reason for a chiller is the protection it provides to your valuable process equipment-- such as spot welders, injection molding equipment, and other applications. A chiller commonly represents a small fraction of the cost of the processing equipment, yet it provides solid protection of your investment, 24 hours a day, 7 days a week for years and years to come.

Increased Production
The speed and accuracy of production will increase as you maintain a constant and proper cooling temperature in your equipment. A chiller will reduce the number of rejected parts while increasing the number of parts produced per hour. You may ask yourself: "Does my equipment shut down during summer months?" -- "Are there periods where our rejection rate increases?" A water tower may provide adequate cooling during fall and winter months, but fail during the hotter periods of the year. A water chiller will immediately eliminate this problem. 

Eliminate the Guess work
Do you have a "genius" at your company whom you depend on to adjust the flow of city water or tower water in an effort to provide enough cooling? Let chiller technology take care of the problem. With a properly sized chiller installed, you simply set the chiller temperature and the solid state "genius" inside the chiller maintains your constant source of chilled water. 

Save Water and Related Costs
Do you use city water? "Yes, only 10 gallons per minute (1.2 million gallons of water per year)." What is the cost of that water? What are your sewage costs? Have you heard of the EPA? Of water shortages? Around the country there is a growing recognition of the tremendous cost associated with using city water for process equipment. Should you do a cost analysis, you would be pleasantly surprised to realize how quickly a chiller ends up paying for it's self and then saving you money from there on out, for years to come. 

Sizing a Chiller Correctly

The importance of selecting a correctly sized chiller cannot be downplayed. An undersized chiller will always be a problem-- never able to properly cool the process equipment. An oversize chiller will never be able to run at it's most efficient level. Specify he correct size chiller and enjoy years of continuous, efficient service. If you would like help, feel free to give us a call. We do this all the time.

To size a chiller properly you first need to calculate the delta T between the inlet and outlet water (the change in temperature), and the rate of flow in gallons per minute (GPM). Measuring the delta T requires a thermocouple or thermometer. Check the water temperature of the water inlet line and the water outlet line, and subtract the numbers to compute how much heat the equipment is adding to the water. 
To measure the flow rate of the water place a flow meter on the outlet line of your equipment. If one is not available, simply measure the time it takes for the outlet flow to fill a five gallon bucket, and then compute your gallons per minute (GPM) of flow.
 

Now that you have these two figures you need to calculate how many BTU's (British Thermal Units) your equipment puts off. Here is the formula:
# BTU/ hour = 500 (the weight of water) x GPM x Temperature Difference (delta T)
Repeat this for all the equipment you have, and add up the total BTUs.

Now that you have the BTUs, lets compute the total Tons of cooling you need from a chiller. 1 Ton of cooling is 12,000 BTU/hour so...
# Tons = (BTU/hr) / (12,000)

This is the size unit you should need. There may be other circumstances, like planning for expansion, that would lead you to buy a different size unit.

Other things to consider when choosing a Chiller: 

1. Is the chiller ARI Rated?
The ARI (Air Conditioning and Refrigeration Institute) sets the national standards for how to rate BTU's in the chiller industry, just as UL (Underwriter's Laboratories) sets the standards for the electrical industry. The ARI National testing standard is 44°F chilled water, tested at 95°F ambient temperature. Some chiller manufacturers rate their chillers at their won standards of 50°F or higher chilled water temperatures.

2. Is the system Contaminate Free?
Having a contaminant free "closed loop" system will increase your chiller's efficiency and lengthen it's life. All Schreiber chillers use either a Stainless Steel or Bronze water pump, and Stainless Steel water reservoirs. 

3. What is the quality of the Compressor?
Every Schreiber chiller uses a "world famous" Tecumseh compressor. Hermetically sealed, the Tecumseh compressor eliminates many design problems associated with other compressors.

Why a Schreiber Chiller?
The quality and reliability of a Schreiber chiller will protect you equipment investment, improve productivity, and save you considerable money. We are proud to provide superior water chillers that meet a variety of cooling applications. 

When you consider the savings in water, sewage, and equipment costs, a chiller makes good business sense and positively effects your bottom line.
