Dual Channel Chiller for Lasers
HRL is a temperature control device featuring two cooling channels in one package. This chiller is 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. Features include a touch panel for operation, fan-cooled refrigeration circuit, and independent coolant ports for each laser component. The HRL targets large output lasers of 5kW or more. The heating function uses waste heat from the refrigerant discharge instead of a separate electric heater to improve efficiency and reliability.

HRLF, Air Cooled Dual Channel Chiller for Lasers, Low GWP Refrigerant
The HRLF air-cooled dual channel chiller is a highly specialized piece of equipment designed to cool fiber lasers. It is specifically engineered for the architecture of a fiber laser and solves three problems:
- space constraints
- complex thermal demands
- strict environmental regulations
The HRLF reduces costs and takes up 30% less floor space than a similarly sized two-chiller setup.
HRLF, Water Cooled Dual Channel Chiller for Lasers, Low GWP Refrigerant
The HRLF water-cooled dual channel chiller is a premium, high-efficiency cooling solution built as an outstanding solution for high-power fiber laser systems. Ultra-high-power lasers generate immense heat. An air-cooled chiller of this size would typically exhaust enough hot air to overwhelm a building's HVAC system. However, because this HRLF is fanless, it is whisper-quiet and vibration-free, ensuring it won't interfere with sensitive laser alignment or contaminate the air.
HRL, Dual Channel Chiller for Lasers
The HRL meets the needs of industrial operators and engineers who work with high power laser applications. It has been designed to cool industrial lasers with enormous power outputs. Energy saving features include a triple inverter to control the power consumption of the fan, pump, and compressor and a heating function that recycles hot exhaust gas from the compressor instead of using a separate electric heater. The immersion pump is sealless which eliminates downtime caused by leaks. The HRL is copper free and includes a deionized water filter as standard; a requirement for high-end laser equipment to prevent internal corrosion.
