Compact Refrigerant Unit

Sanden’s CRU reduces the refrigerant system components to a minimum. Energy is transferred from refrigerant to coolant and subsequently to air (using a separate water module). Our design eliminates refrigerant exposure in the passenger compartment, enabling the safe use of flammable refrigerants.

Features

One chiller design: reduced refrigerant system complexity& component cost
Easily customizable: Sanden’s CRU concept allows easy and efficient customization
Fully validated simulation model available, an FMU can be provided to support system layout development.

Technical Specifications

Refrigerant: R290 (Propane) for high efficiency and low environmental impact
Heating & cooling: up to 12kW can be generated
Wide operating range: reliable performance from -40°C to +50°C
Direct water module assembly or alternative connection via hoses
Electrical: power side 800V, signal side 12V (24V with additional DC/DC converter if needed).

Key Technologies

R290 optimized electric compressor
Fully balanced component orientation with decoupling elements in carrier structure
Refrigerant isolation: eliminates refrigerant lines in the passenger cabin, enabling safe use of flammable refrigerants like R290
Optional R290 sensor for safety management.
