CHILLERS

A Long History: UNITROL has manufactured quality process water chillers since 1971. Our chillers are designed to operate continuously in industrial environments.

TYPICAL APPLICATIONS

Customizing a UNITROL Chiller: UNITROL can modify any chiller model to handle special applications such as:

Non-Refrigerated Coolers: UNITROL also manufactures non-refrigerated systems that will cool water down to as low as 5°F above room temperature. These systems include a fine-finned radiator, water tank, water pump and controls. Sizes range from nominal 24,000 BTU/Hr to 1,000,000 BUT/Hr.  Contact UNITROL sales to select the appropriate model number.

Outdoor Applications: Chillers can be ordered with outdoor kits installed for use in any ambient temperature.

Water Cooled Chillers: Standard model chillers are provided with Air Cooled Condensers. UNITROL can also provide any of our chillers with Water Cooled Condensers.

WATER CHILLER AND INLINE BOOSTER MASTER CHART

CHILLERS: These units are self-contained and include a WATER TANK and WATER PUMP. Chillers recirculate water and are considered "Closed Loop" systems.

INLINE BOOSTERS: Boosters use water supplied from an outside source and do not include a WATER TANK or WATER PUMP. Inline Boosters do not recirculate water.

NOTES:

1. CHILLERS include a WATER TANK and WATER PUMP. Other size water pumps are available to produce higher water pressure or water flow rates.

2. INLINE BOOSTERS use water pushed from an outside source and do not include a WATER TANK or WATER PUMP.

3. REMOTE CONDENSER: Models ending with "R" are shipped in two pieces. The inside component contains water tank, water pump, controls, and cooling evaporator. The outdoor component contains compressor, and heat-producing condenser. Customer field installation of refrigeration piping and electrical control lines is required. Dimensions shown are for the inside components only.

4. RESISTANCE WELDING APPLICATIONS: When used to chill resistance welders. this column is calculated to cool up to the listed quantity of 75 KVA or smaller single point spot welders under typical conditions. For other applications consult Unitrol for sizing assistance.

5. MODEL 8000 is designed to chill one spot welder (40 KVA or smaller) or up to two 250A TIG welders. It can also be used for small laboratory processes.

6. These Models are dual compressor systems. They are supplied in two modules, each with the dimensions shown. The total weight for the two modules is as shown on the chart.

USING UNITROL CHILLERS FOR RESISTANCE WELDING APPLICATIONS

UNITROL chillers are designed to handle a large variety of industrial water cooling applications. Over the years, UNITROL has produced a large volume of chillers for use in resistance (spot) welding applications. Our experience in sizing chillers used in welding lines allows us to provide the most economical match of chiller and application.

WHY YOU NEED THE UNITROL SYSTEM FOR YOUR WELDING LINE

All UNITROL Spot Welder Chillers are self-contained, closed-loop refrigeration systems which recirculate a continuous supply of cold water virtually eliminating all water consumption. This means it's unnecessary to use city or well water which presently contaminates your water lines. So down-time for cleaning and descaling of mineral deposits is totally eliminated.

Consistent pressure and low temperature is also maintained in the cooling water, helping to reduce down-time for copper tip replacement as much as 50%. Your weld quality and uniformity is also greatly improved. The result is increased production, more efficient operation, more actual output hours. After all, it's only when your machines are running that you're turning out billable product.

UNITROL CHILLERS PAY FOR THEMSELVES IN THE FIRST YEAR

You will immediately realize an impressive increase in quality production and output hours with drastic reduction of costly tip replacement. As an example, an elimination of as little as 10 minutes per day of tip dressing represents a typical annual savings per operator of over $1,000.00. By adding the elimination of costly water, high sewer taxes, and EPA mandated water processing, you can easily realize a payback of the entire chiller cost within 5 to 12 months.

Another money saving tip: The air exhaust from the chiller can be used to heat your building, and the heat can be exhausted out during the warm months.
