Product catalog summary

Introduction
Alfa Laval introduced its first brazed plate heat exchanger in 1977 and has since optimized its performance and reliability. The brazing of stainless steel plates eliminates the need for gaskets, making the heat exchanger compact and efficient.

Product Overview
The AlfaChill (AC) brazed plate heat exchangers are designed for air conditioning, refrigeration, and heat pump applications. They feature a patented distributor integrated into the plate design for high efficiency.

Applications

Evaporation in chillers and heat pumps
Condensing in chillers and heat pumps

Refrigerants and Capacity
The standard design supports HFC refrigerants like R407C, R404A, R507, and the high-pressure version is suitable for R410A and natural refrigerants. The capacity range is 50 kW to 250 kW for chillers and 30 to 150 kW for heat pumps.

Quotation Requirements
To receive a quotation, provide flow rates, temperature program, brine and refrigerant type, desired working pressure, maximum water/brine pressure drop, and connection types.

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. Request for quotation To receive a quotation for brazed plate heat exchangers that meet your requirements, please provide Alfa Laval representatives with: - Required flow rates or heat load - Temperature program (inlet and outlet) - Brine and refrigerant type - Desired working pressure - Maximum permitted water/brine pressure drop - Connection types
