This heat exchanger size is 706x296mm2. There are 3 different types of such size BPHE. We have Medium and High pressure drop and heat transfer models, those models can also use the ejector system. One model with low pressure drop on one side and high on the other. That means that we have several heat transfer areas integrated in same heat exchangers. For EC89 special made for water chillers and heat pumps condenser, under cooler, ejector, evaporator and super heater are integrated. DH89 is for apartment houses.
