HRLE, Basic Dual Channel Chiller for Lasers

The HRLE 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. Considerabe space savings can be realized compared to a two chiller solution. All operation can be managed from a single touch panel. Compared to the HRL, the HRLE targets medium-sized 3-4kW lasers and simplifies the internal components. Space and energy are saved using a single fan, compressor, pump and tank. The heating function uses waste heat from the refrigerant discharge instead of a separate electric heater to improve efficiency and reliability. Several features are optional to reduce the cost of the basic unit. These options include DI water capability, electrical conductivity control kit, bypass piping, automatic water fill kit, particle and fluid fill filters, and a ball valve set for adjusting coolant pressure and flow rate.
