MGR 500W Recirculating Chiller
Designed for continuous operation and easy integration, the MGR delivers dependable temperature control for industrial processes and equipment.
The MGR is a compact recirculating chiller designed for laboratory, industrial, and OEM applications requiring reliable, repeatable cooling performance.
Built using vapour compression technology and a brazed plate heat exchanger, the unit delivers constant temperature control in demanding environments while maintaining a small footprint.
Its robust construction and simple operation make it well suited to integration within machinery, production lines, and process systems.
Key Features
Consistent temperature control (±0.1°C ) – Ensures stable operation for repeatable industrial processes.
Compact, integration-friendly design – Ideal for OEM equipment and space-constrained installations
R290 natural refrigerant – Energy-efficient with low environmental impact
Industrial-grade components – Designed for reliability in continuous operation
Integrated communications as standard – Includes RS485 communication for remote setpoint adjustment and volt-free contacts for alarm signals and remote monitoring
