Sanhua Expands Refrigerant Control Offering with DBF and SEC711

In the context of an HVAC-R sector increasingly oriented towards energy efficiency, sustainability and intelligent control, Sanhua introduces two new solutions dedicated to advanced refrigerant management : the DBF series of electronic expansion valves and the SEC711 controller .

The integration of these components allows for the creation of an advanced technological platform, designed to improve the performance of commercial refrigeration, air conditioning, and heat pump systems.

DBF: precise and bidirectional refrigerant control

The new DBF series represents an evolution in refrigerant flow control, thanks to an optimised design that allows precise, bi-directional adjustment.

Among the main strengths :

• high reactivity and opening/closing speed
• compact design and simplified installation
• compatibility with low GWP and flammable refrigerants (R32, R290, R1234yf, R1234ze)
• optimised operation even in dynamic conditions

These features improve system efficiency and operational stability, adapting to the needs of modern HVAC-R systems.

SEC711: Intelligent overheat control

Completing the range, the SEC711 controller has been developed to ensure extremely precise superheat management, helping to maximise evaporator performance.

The system integrates advanced regulation algorithms that allow:

• automatic and accurate control of the refrigerant flow
• operational stability even with load variations
• energy efficiency optimization

Compatible with various Sanhua components – including expansion valves, motorized ball valves and pressure sensors – the controller enables more intelligent and integrated systems.
