Efficient & reliable package solution for refrigeration from SANHUA

Since many years Sanhua is a leader in development and manufacturing of electronic expansion valves for HVAC&R industry. Focus was given on electronic expansion valves (EEV) for OEMs who had their own controller for EEV or third-party controllers in combination with SANHUA EEV.

Due to increased demand for Sanhua products in Wholesalers and Installers (WS/I) market, particularly for electronic expansion valves series DPF, company developed complete package solution especially adopted to the needs of WS/I and small OEMs:

DEDICATED CONTROLLER 

ELECTRONIC EXPANSION VALVE 

PRESSURE AND TEMPERATURE SENSOR

Electronically operated expansion valves are offering significant benefits compared to thermostatic expansion valves:

1) Wide capacity regulation range for the same model
2) Same model for different refrigerants
3) Stable valve capacity at minimum pressure drop
4) Precise capacity regulation
5) Additional level of system protection, monitoring and remote control

Before releasing the new EEV controller and existing electronic expansion valves DPF Sanhua did extensive tests of controller with the valve to achieve best performance for typical refrigeration applications served by WS/I. This was done to offer for customers complete package solution, tested, qualified and ready to use in refrigeration applications. The second important target was to offer cost efficient solution to be able to compete with traditional mechanical expansion valves considering increasing demand for high energy efficient solutions.

„BRGroup“ Technical director notices: „Customers used combination of Sanhua EEV and controller from third party manufactures earlier. This solution worked, but without smooth and precise regulation, it was not easy to adjust controller settings to each EEV, it took long time and only experienced installers were able to do this. With new Sanhua EEV package solution controller parameters are already adjusted to Sanhua EEV, PID algorithm optimized for precise flow regulation. Sanhua package solution is user friendly and easy to use even by installers without deep experience in electronics“.
