H05 5.5kW Recirculating Chiller
Built for performance and reliability, the H05 delivers powerful cooling and precise control for higher-load industrial environments.
The H05 is a recirculating chiller designed for industrial and process applications where greater cooling performance and reliability are essential.
Utilising vapour compression technology and a brazed plate heat exchanger, the unit delivers stable, efficient cooling across a wide operating range.
With flexible pump options, robust construction, and advanced control capabilities, the H05 is well suited to demanding systems requiring continuous operation and consistent performance.
Key Features
Precise temperature control (±0.1°C ) – Ensures stable and repeatable process conditions
Flexible flow and pressure options – Pump configurations from 5 to 25L/min for system flexibility
Low GWP refrigerant (R454C) – Supports the transition to more sustainable cooling solutions
Robust, industrial design – Powder-coated 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
Single-phase high-capacity performance – The H05 is one of the largest chillers in the ATC range suitable for single-phase operation using a 16A commando supply, ideal for facilities without three-phase power availability.
