H12
Introducing the H12 recirculating chiller – a high-performance F-Gas compliant solution purpose-built for precise temperature control in both laboratory and industrial environments. By using a lower GWP refrigerant (R454C), this chiller delivers up to 12kW of cooling capacity at +20°C ambient temperature and set point. With its robust steel enclosure, portable castors, and configurable options, the H12 is engineered to suit a to anything from battery and electric vehicle testing to advanced research instrumentation, providing both heating and cooling functionality when required.
