H03 3.4kW Recirculating Chiller
The H03 is a versatile recirculating chiller designed for laboratory and industrial process cooling applications requiring greater cooling capacity than a smaller benchtop system while maintaining a compact footprint.
Utilising vapour compression technology with a brazed plate heat exchanger, the H03 delivers reliable and stable temperature control across a wide operating range. Flexible pump options, advanced PID control, and robust industrial construction make it well suited to OEM integration, research facilities, and process cooling applications where consistent performance and continuous operation are essential.
