Hydraulic Oil Chillers
Process oil used for applications such as hydraulics, cutting, lubrication, broaching, honing, quenching, drilling, grinding etc., also aid as a cooling media. In other words, the heat dissipated during the process is carried away by the circulating oil. Now this oil needs to be maintained at a certain temperature range to retain its physical and chemical properties.
Our oil chillers adopt the most proven design to suit specific application. In applications where direct oil cooling is not advised, we suggest a double ckt chiller, where water acts as the secondary refrigerant. Oil chillers are available in configurations like, Stand alone, in which the oil re-circulating pump is integral with chiller and the Immersion type, in which the evaporator coil is dipped directly in to the oil sump.
Application
- Hydraulic power packs

- Component quenching
- Machine tools
- Broaching machines
- Honing machines
- Deep hole drilling machines
- Pipe bending machines
- Year round operation/ allows equipment to run continuously due to controlled oil temperature
- Meets the varied needs of cooling capacities from 0.5 TR to 40 TR
- Oil temperature can be maintained between 25 deg. C to 40 deg. C
- High efficiency plate heat exchangers assures energy efficient operations as well as precise cooling.
- Rugged design: The system cabinet and components are rugged enough for continuous and reliable industrial operation.
- Micro processor based digital temperature controllers ensures tamper proof and precise operation
- High efficiency gear pumps for reliable and continuous operation
Compressor, fan and pump are independently electrically operated.
- Factory packaged and tested systems/wired, charged and piped. Tested for operation and cooling performance before installation.
Operational features:
- Microprocessor based chiller controller
- RS 232/485 communication ports fro inter locking chiller controller with the main machine controller
- Refrigerant gauges- for continuously monitoring and display of suction and discharge refrigerant pressures
- Filters-online filters with specific micron levels can be assembled in the fluid line wherever oil requires fine filtration .
- Indirect oil cooling by installing a water chiller and a circuit breaker heat exchanger can be chosen wherever circuit breaking is desired for reasons like maintenance wherever oil temperature requirement above 4 deg. C and wherever installed cooling capacity goes above 30,000 kcal/hr
- Cooling and heating options can be incorporated in the same package for special test rigs and regions of installations where ambient temperatures are lower than 20° C
