Chillers – Dual Channel Chiller for Lasers
The HRL and HRLE are temperature control devices featuring two cooling channels in one package. These chillers are specifically 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. Both types feature touch panels for operations, fan-cooled refrigeration circuits, and independent coolant ports for each laser component. The HRL has extensive standard features and targets large output lasers of 5kW or more. The HRLE is for medium output lasers of 3-4kW, with a patent pending simplified circuit design for a single tank and pump. The heating function uses waste heat from the refrigerant discharge instead of a separate electric heater to improve efficiency and reliabilty.
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. Heat extracted by the refrigerant cycle can be either cooled with a fan (air type) or with facility water (water type). Space and energy are saved using a single fan (air type), 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.
