Applications:

• Hydraulic power pack
• Lubricating oil cooling
• Any other oil with viscosities ranging between 20 to 100 CST

Models:

• Direct cooling
• In-direct cooling

Direct Chilling:

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 chilling:

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.
