Hydraulic Oil Chillers

Sophisticated multi tasking machines of today employ numerous hydraulic operations to achieve high productivity at desired quality levels. Hydraulic systems in turn employ special and specific oil with a wide viscosity range. These hydraulic oils stores heat during its operation and the continuous addition of heat reduces the viscosity of these oils. As the oil thins down, the hydraulic system starts to malfunction due to internal leaks. Therefore it becomes essential to maintain specified temperature limits for this oil during operation. A hydraulic oil chiller is normally connected in parallel to the oil tank through a dedicated built in pump.
This industrial hydraulics Oil Chillers is complete systems fitted with refrigeration components including the compressor, condenser, evaporator, refrigeration pipes, oil pump and electric panel. Chillers help maintain the oil temperature to precise temperature levels which in turn maintains uniform physical and chemical properties of the oil in operation. THIS LEVEL OF precise temperature control of fluids is not possible by any other method of cooling. Critical industrial hydraulics have special needs beyond mere cooling such as year round operation, precise temperature regulated and a lean circulating loop: which is only possible with equipment matched factory tested Industrial Oil Chiller.
Hydraulic Oil Cooler
Heavy duty Oil cooler
Our range of hydraulic oil chillers, oil coolers 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 pump. In applications where direct oil cooling is not suggested, we suggest a double ckt chiller and cooler, where water acts as the secondary refrigerant.
Process oil is used in hydraulics, cutting, lubrication, broaching, honing, quenching, drilling, grinding etc., also aid as a cooling media. In other words, the heat is dissolute during the process when 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.
APPLICATIONS

• Hydraulic power pack

• Lubricating oil cooling

• Any other oil with viscosities ranging between 20 to 100 CST

Models:
Direct Cooling:
Applications demanding cooling capacity below 30,000 Kcal/hr can be installed with a direct oil chiller, where the hydraulic oil from the tank will be drawn by the pump installed in the cooling system and the oil will be cooled to the desired level and re-circulated back into the tank. This system can be used on hydraulic power packs which do not come with a standard fitment water to oil heat exchanger, therefore making t very popular in the retrofit market
In-direct Cooling: 
Applications demanding cooling capacity more than 30,000 Kcal/hr cannot be installed with a direct oil chiller due to various design related reasons. Therefore, the in-direct type comes in handy for such applications. The in-direct chiller is a package complete with a process water chiller, plate heat exchanger and oil pump. The oil pump will draw oil from the hydraulic oil tank and re-circulate the same on one side of the plate heat exchanger. On the other side of the plate heat exchanger, the process water chiller will re-circulate chilled water at a lower temperature than the required oil temperature. The microprocessor based temperature controller will sense the oil temperature at the inlet to the plate heat exchanger and regulate the chilled water flow in order to maintain a constant and healthy oil temperature.
