CHILLERSare generally used to cool & maintain the temperature of coolant / oil / water or other media. Temperatures can be set either with respect to ambient or at a fixed value. These chillers work using the principle of refrigeration. Good quality components are used to ensure reliability & long life of Chillers.
APPLICATIONS: - WATER CHILLERS :These are used : 1) to cool x-ray / laser heads, heating coils of induction hardening machine etc.2) on sub zero applications like testing performance of components at below zero degree centigrade etc.
- OIL / COOLANT CHILLERS :These are used to cool Hydraulic oil, coolant oil or emulsion coolant. Maintaining a constant hydraulic oil temperature at allowable limits helps to stabilise the performance of hydraulic powerpacks. Controlled coolant temperature increases the tool & coolant life, gives better & consistent accuracy of machining or grinding operations and thus improves process & machine capability values.

WE MANUFACTURE DIFFERENT TYPES OF CHILLING UNITS SUCH AS: - A1- STAND-ALONE TYPE CHILLER :These Chillers have their own pump and a Stainless Steel ( SS ) or Mild Steel ( MS ) tank where the hot / warm medium is cooled and pumped back to the machine / equipment for continuous circulation.
- A2- DIP IN TYPE CHILLERS :Here the evaporator / cooling coil of the chiller is directly dipped into the tank containing the medium to be cooled & the top of the chiller rests above the tank. The heat from the medium is removed by the dipped coils.
- A3- CHILLERS WITH HEAT EXCHANGER :These Chillers have their own heat exchanger, either Plate Type / Compact Brazed type or Shell & Tube type in SS or MS having evaporator / cooling coils, which reduces the temperature of the medium. This unit can also be given with a pump for continuous circulation to the machine / equipment.
- B1- CHILLERS WITH DIFFERENTIAL TEMPERATURE CONTROLLER:These chillers control the medium temperature within + or - 10 deg C with respect to ambient temperature.
- B2- CHILLERS WITH FIXED POINT TEMPERATURE CONTROLLER:These chillers control the medium temperature with respect to a pre set value of temperature.
- B3- CHILLERS WITH HEATING & COOLING :These chillers control the medium temperature very quickly at a constant value within a close tolerance band of temperature. Any combination of the above types, A & B, can be made to meet very specific requirements.
