SWEP has announced the introduction of the FTW250AS brazed plate heat exchanger (BPHE), the first BPHE based on the company's novel Hypertwain technology.
The FTW250AS BPHE primarily targets reversible chillers and heat pumps. Unlike a standard BPHE, Hypertwain features an integrated suction gas heat exchanger (iSGHX) that improves the evaporator performance.
This feature helps OEMs design and bring products to market with unrivaled seasonal efficiency in both heating and cooling mode, as well as reducing the refrigerant charge and footprint.
The integrated iSGHX also enables control stability compared with an external SGHX. In addition, Hypertwain also improves freeze resistance and reduces water pressure drop.
Hypertwain integrates several functions critical for evaporator and condenser duties in chiller and heat pump applications.
The FTW250AS covers a capacity span up to around 70 USRt while the Hypertwain platform is being extended with additional BPHEs aiming for capacities up to 200 USRt with both single and dual circuits.
Focus refrigerants are all high-pressure refrigerants, such as R32, R410A, R454B, R452B, as well as being verified for R290 (Propane).
