Reliable Liquid Cooling for Industrial Machinery
Industrial machinery, machine tools, process systems and power electronics can generate significant quantities of heat that cannot always be managed effectively using conventional enclosure air cooling. The Rittal SK3335.790 circulates temperature-controlled cooling medium through the connected equipment, transferring unwanted process heat to the chiller's refrigeration circuit and helping maintain stable operating conditions.
Its integration into the Rittal TS 8 enclosure platform makes the chiller particularly suitable for installation alongside electrical and automation enclosures. The combination of microcontroller-based temperature regulation, icing protection, a high-capacity coolant tank and dual-frequency compatibility provides a dependable cooling platform for machine builders and industrial system integrators.
