Hydraulic Oil Chiller

The oil chiller is a unit which performs cooling of the hydraulic oil, lubricating oil and cooling oil of machine tools. The Hexacool Oil Chiller performs cooling down by circulating oil and thus prevents oil temperature rise. The environmental resistance is also significantly improved compared with conventional units.

Hydraulic Oil Chillers maintain the temperature of hydraulic oil and thereby its viscosity for smooth working of machine tools.

Hexacool process cooling Hydraulic Oil Chillers are used to maintain precise oil temperature in the powerpacks which are used in hydraulic systems of CNC machine tools, high speed presses and hydraulic powered special purpose machines and hydraulic equipment.

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. Hexacool’s Chillers are built with 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.
