Sanhua have obtained EU PED certification and our BPHEs
work with fluid groups 1 and group 2, including water, ethylene glycol
solution, common HCFC, HFC, HC, as well as HFO refrigerants such as R410A, R32,
R454B, R290, R134a, R404A, R507, R448A, R449A, R1234yf, R1234ze and R452A. The
designed pressure is up to 50 bar. Our full range of stainless steel BPHEs is suitable
for many different applications including as heat pumps, chillers and boilers.
Our wide range of BPHEs include many different sizes and
models; evaporators, condensers, de-superheaters, fluid to fluid exchangers and
compact exchangers that are easy to install, gasket free, and with a fully hermetic
design. The main benefits of which are:
· Asymmetric Plate
By introducing an asymmetric plate design, we have reduced
the volume of the primary side to increase the evaporating temperature and heat
transfer efficiency, while still keeping the pressure drop within an acceptable
range. Our data shows a dT that is on average 1K lower and a pressure drop
25% lower than similar asymmetric design products.
· Anti-freezing design
In the scenario of refrigerant/water exchange, it is
necessary to prevent the water temperature from falling to freezing point and
the plates from cracking.
· Plate with reduced depth
By reducing the depth of the plate, heat transfer efficiency
has been improved while still keeping the pressure drop within an acceptable
· Highly efficient distributor
The Sanhua distributor has its own design patent, where the
distribution holes are part of the plates making the heat exchanger extremely
· Temperature fatigue resistance
Temperature fatigue happens mostly in heat pumps or cascade
systems where high and low temperatures exchanges occur frequently, leading to the
brazing between the plates failing.
