The HRL is a temperature control device featuring two independent cooling channels in one package. This thermo chiller is designed to cool the optical head and oscillator of a laser processing system. Considerable space savings can be realized compared to a two chiller solution. All operations can be managed from a single touch panel. A triple inverter controls power consumption of the fan, pump, and compressor for optimal energy savings. The heating function uses waste heat from the refrigerant discharge instead of a separate electric heater to improve efficiency and reliability. The HRL is copper free and suitable for DI water, including a DI filter and electrical conductivity control kit. Additional standard features include a 5µm particle filter, earth leakage breaker, and casters for mobility.
