Oil Chillers

Hydraulic Oil Chiller- I HOC

Most manufacturing units and processes use hydraulics based machinery. These machinery make use of hydraulic oils of varying densities which heat up periodically during the course of the manufacturing process. However, having the oil heat up causes it to lose some of its characteristic properties and renders it useless for the process. In order to increase the shelf life of hydraulic oil and the machinery that it belongs to, it is important to regulate the temperature of the oil and constantly cool it. This is achieved with the aid of hydraulic chillers which are usually connected directly to the oil supply and in-built pumps. The heated oil is circulated through the chiller circuit and its temperature is thus controlled. Werner Finley’s Chillers are built with internal gear pumps and plate heat exchangers for this application. These ensure higher cooling efficiencies and lower noise levels. These can be utilized for processes using oils of viscosities ranging from 32-68 CST.
