The pressure transmitter is designed for a reliable and safe installation in sub-critical and trans-critical R744 systems. The new range of pressure transmitter includes models with a design pressure (PS) of 90bar (suitable for all the sub-critical positions) and models with a PS of 150bar for trans-critical installations.

The new range includes ratiometric models with output signals in volts or models with a current signal 4-20mA - almost all YCQx models guarantee a full compatibility with the Sanhua EEV controller SEC61x and the potential to complete the full Sanhua solution for the management of the DPF/LPF uni-polar stepper valves.

Sanhua has also extended electronic expansion valve ranges LPF and DPF with:

• DPF-R for CO₂ with max pressure = 140 bar
• LPF-D for CO₂ with max pressure = 60 bar
• LPF series is extended with new sizes LPF30 and LPF32 which use the same coils as PQ-M24.

The electronic expansion valves LPF and DPF-R are compatible with the Sanhua electronic SEC controller with advanced PID algorithm, pressure transmitter YCQ with features like IP67 and electronic expansion valves.

the Sanhua range for R744/CO₂ includes a range of components for sub-critical applications and trans-critical applications, like ball valves, check valves and others.
