AC232DQ / ACH232DQ Brazed plate heat exchanger with double refrigerant circuit Alfa Laval introduced its first brazed plate heat exchanger in 1977 and has since continuously developed and optimized its performance and reliability. Brazing the stainless steel plates together eliminates the need for gaskets and thick frame plates, which makes the heat exchanger compact and saves material. The brazing material seals and holds the plates together at the contact points ensuring optimal heat transfer efficiency and pressure resistance. Using advanced design technologies and extensive verification guarantees the highest performance and longest possible service lifetime. The AlfaChill (AC) brazed plate heat exchangers are specifically designed for heat transfer in air conditioning, refrigeration and heat pump applications. Innovative features for this high efficiency double circuit heat exchanger with parallel flow, include a patented distributor integrated in the plate design. Typical applications - Evaporation in chiller and heat pumps - Condensing in chiller and heat pumps The standard design supports a wide variety of HFC refrigerants such as R407C, R404A, R507. The high-pressure . version is suitable for R410A and natural refrigerants (CO2 propane). Capacity range AC232DQ / ACH232DQ cover capacities from 50 kW up to 250 kW for chillers and 30 to 150kW for heat pumps and 30 to 150 kW for heat pumps. Based on standard components and a modular concept, each unit is custom-designed for each specific installation.
