• Air flow (evaporator): 1000 m³/h
• Permissible ambient temperature: +5 °C to +43 °C (pure indoor operation)
• Refrigerant: R290 (propane gas) – an environmentally friendly, natural refrigerant with very low global warming potential (GWP 3)
• Refrigerant capacity: < 150 g
• Global warming potential (GWP): 3
• CO₂ equivalent: < 0.45 t
• Defrosting: Automatic hot gas defrosting with demand-controlled cycle control

• Weight: 64 kg (net)

Dimensions for the wall cutout
• Width of the neckline: 575 mm
• Height of the cutout: 395 mm


Key features

• Piggyback design: The monobloc unit is simply hooked into a corresponding section of the cold room wall ("piggyback"). The maximum wall thickness may be 150 mm.
• Hot gas defrosting: The unit has an automatic, demand-controlled hot gas defrosting system with integrated condensation evaporation, so that a separate drain is usually not necessary.
• Smart electronics: Equipped with modern control, Bluetooth connectivity (for app control and data tracking) and automatic leak detection.
• Components: Thermostatic expansion valve, pressure sensors and efficient, internally finned heat exchangers.


Important Operational Instructions

• Ambient temperature: The device is designed exclusively for operation in closed rooms at an ambient temperature of +5 °C to +43 °C. It has no winter control and is not weather-resistant (no outdoor installation).
• Accessories for Viessmann cells: If the WMC3 unit is mounted on a classic Viessmann cold room, a special adapter cable and a converter box are usually required to connect the door contact switch and the power supply without errors.
