Industrial Chillers are set up for any industrial use from Plastics, Machine Tools, Medical and Food Industry. High quality and manufactured in large volumes to keep competitive cost in mind.


 

 


Capacities from 3 ton to 60 tons
Industrial water or air cooled Chillers and Central chilling systems are designed and built in the US with top of the line parts from the US. When you receive our chillers they come almost turn key in the fact that you will only have to hook up piping and power. These units are designed to handle applications such as injection molding all the way to precision cooling with MRI’s and Laser welding.

Outdoor Chiller Considerations

NOTE: Chillers designed for indoor applications should NOT be used outdoors. Only chillers designed for outdoor use will be durable and reliable enough to endure the rigors of the environment. For roof mounted installations, please contact a building architect to verify that the roof structure is capable of supporting a fully charged/filled chiller.

  1. LOCATION: Chiller should be located as near as possible to the equipment being cooled. Direct sunlight on the condensing coil can severely reduce operating efficiency. A shaded location on the north or east side of a building is most desirable. If the chiller has a horizontal discharge, do not face the discharge into the prevailing wind. Service access and the air inlet should be located a minimum of 3 feet (1 meter) from walls and other obstructions. Do not install the chiller in an enclosed shelter unless proper intake and exhaust venting is provided. Do not allow canopies or roofs on open-sided shelters to restrict the air flow on chillers with vertical air discharge. Allow a minimum of 8 feet clearance. Also, be aware of the potential to restrict air flow caused by downdrafts and eddy currents that are created by surrounding structures.
  2. SECURITY: If the chiller will be located near a residential area or potential for vandalism exists, a security fence with a lockable gate should be erected around the chiller.
  3. FOUNDATION: The chiller should be set on a concrete slab. The slab should extend a minimum of 12 inches (30 cm) beyond the perimeter of the chiller to prevent damage from lawn maintenance equipment, etc. The chiller should be level and properly anchored.
  4. FLUID LINES: As the distance from the chiller to the equipment being cooled increases, the pressure drop in the supply and return fluid lines for a given line size and pressure will increase. In order to minimize pressure drop, refer to a friction loss chart for various pipe sizes to determine the proper piping diameter for the given distance.
  5. AMBIENT TEMPERATURE: When outdoor ambient temperatures will be above 95 degrees F. (35 degrees C.) or below 50 degrees F. (10 degrees C.), the chiller manufacturer should be consulted. High ambient temperatures reduce chiller capacity. Low ambient temperatures require special controls. Special conditions apply when temperatures drop below 32 degrees F. (0 degrees C.). Fluid heaters may be required to prevent freezing and to hold the fluid in the chiller reservoir at a constant temperature in order to reduce start-up delays while the fluid warms up to operating temperature.
  6. ELECTRICAL: A remote indoor electrical panel that displays chiller status and houses the temperature controller and on/off switch is recommended.
  7. RESERVOIR: The chiller reservoir should be filled to the proper level with an inhibited glycol designed for HVAC/R systems. Do not use automotive antifreeze. The inhibitors used in automotive antifreeze can break down quickly and accelerate the degradation of the coolant base (glycol); as well as promote corrosion in a system. Silicates used in automotive antifreeze coat heat exchangers, resulting in reduced heat transfer. Also, silicates can gel causing fouling and plugging of a system.

The ratio of inhibited glycol to water should be adequate to prevent freezing at the lowest ambient temperature. Check the level with all lines filled. The glycol mixture should be checked periodically (3 to 6 months) for proper concentrations. When filling the system, always use a pre-mixed solution in the proper ratio to maintain freeze and corrosion protection. Distilled or deionized water is recommended because many municipal water supplies contain large amounts of chlorine, which can react unfavorably with glycol.

NOTE: If supply and return lines are overhead, the fluid in the piping may drain back and overflow the chiller reservoir if the chiller is shut down. This can be prevented by using a check valve in the supply line, and either an inverted trap with a vacuum breaker or a solenoid valve on the return line.
