The solution comprises the new
SANHUA VSD2010P driver and the company’s LPF-D series unipolar stepper motor
EEV (electronic expansion valve). SANHUA’s innovative LPF-D
EEV (500 steps) ensures reliable solutions for CO2 installations
with design pressures up to 60 bar. Notably, the driver features an integrated
supercapacitor and simply use the 0-10 VDC output signal
from the superheat controller to drive the VSD2010P.
R744 is a
popular use as a replacement for R134a and R404A in ultra-low, low and medium
temperature refrigeration applications. SANHUA’s innovative new solution can
help simplify the transition process thanks to its ‘plug n play’ functionality.
Ultimately, it is now possible to
maximise the benefits of common case controllers with smooth and precise
stepper EEV technology from SANHUA in a cost-effective and convenient way.
SANHUA’s offer for CO2
includes a wide range of components for sub-critical and trans-critical applications,
including pressure transmitters, ball valves, check valves and more. The
company is the world’s biggest EEV manufacturer, supplying more than 40 million
EEVs to the refrigeration, automotive, heat pump and AC industries every year. SANHUA
customers can rely on adaptive production capacity, continuous deliveries and
stock availability.
