The Wöhler SC 660 Smart Connect is your ideal entry point for quick checks and forms the basis for hose-free, simple pressure and temperature measurement directly at the service connection. It is perfect for quickly checking the system status, for example operating pressure, superheating and subcooling. There is no loss of refrigerant and evacuation of the hoses is not necessary. This makes the Wöhler SC 660 Smart Connect particularly interesting for companies that want to carry out initial checks easily and safely.

The Wöhler MR 660 Refrigeration Valve Block complements the Wöhler SC 660 Smart Connect specifically when work such as commissioning, maintenance or decommissioning is required. It has four connections for the refrigerant cylinder or a recovery device, the refrigeration circuit, the Wöhler SC 660 Smart Connect and the vacuum pump, and is also compatible with flammable refrigerants of classes A2, A2L and A3*. Three separately controllable valves increase clarity and safety. In addition, a connection for potential equalisation ensures even greater safety. This makes the Wöhler MR 660 Refrigeration Valve Block ideal for all situations in which you need to intervene in the refrigeration circuit.

The Wöhler Smart Connect App connects all components of the system to form a convenient complete solution. It guides you step-by-step and illustrates the commissioning and decommissioning of heat pumps and refrigeration systems, showing you visually how to connect individual components such as hoses, vacuum pumps or recovery devices correctly. The measured values are automatically transferred to a log p/h diagram – the system status can be seen at a glance. In addition, the app documents all measurements completely and comprehensibly, thereby increasing operational and application safety – even if refrigeration technology is not part of your daily business.
