H06 6.5kW Recirculating Chiller
Engineered for higher cooling loads and continuous operation, the H06 delivers powerful, precise temperature control for complex systems and larger-scale processes.
The H06 is a high-capacity recirculating chiller designed for industrial and process applications requiring greater cooling performance, scalability, and system flexibility.
Utilising vapour compression technology with a brazed plate heat exchanger, the unit delivers efficient, stable cooling across a wide operating range.
With a significantly higher flow range and multiple pump configurations, the H06 is ideal for larger systems and more complex installations where consistent performance is critical.
Key Features
Precise temperature control (±0.1°C ) – Ensures stable and repeatable performance
Extended flow capability – Suitable for larger systems and complex process requirements
Low GWP refrigerant (R454C) – Supports the transition to more sustainable cooling solutions
Robust, industrial construction – Heavy-duty steel enclosure with castors for durability and mobility
Integrated communications as standard – Includes RS485 communication for remote setpoint adjustment and volt-free contacts for alarm signals and remote monitoring
