Brazed Plate Heat Exchanger AC120EQ / ACH120EQ

Brazed Plate Heat Exchanger AC120EQ / ACH120EQ

Product catalog summary

General Information
Alfa Laval introduced its first brazed plate heat exchanger in 1977, continuously enhancing its performance and reliability. The brazing of stainless steel plates eliminates the need for gaskets and thick frame plates, resulting in a compact design that optimizes material use. The brazing material ensures optimal heat transfer efficiency and pressure resistance. The AlfaChill (AC) series is tailored for air conditioning, refrigeration, and heat pump applications, featuring the patented Equalancer SystemTM for efficient refrigerant distribution.

Typical Applications

Evaporator and condenser in chillers and heat pumps
Economizer in chillers and heat pumps

The standard design accommodates various HFC refrigerants, including R407C, R404A, R507, and R134a. The high-pressure version is suitable for R410A and natural refrigerants like CO2 and propane.

Capacity Range
The AC120EQ / ACH120EQ models cover capacities from 20 to 200 kW. Each unit is custom-designed based on standard components and a modular concept.

Brazed Plate Heat Exchanger AC120EQ / ACH120EQ-1

AC120EQ / ACH120EQ Brazed plate heat exchanger General information 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 single circuit heat exchanger include the patented Equalancer SystemTM for efficient distribution of the refrigerant throughout the plate pack. Typical applications - Evaporator and condenser in chillers and heat pumps - Economizer in chillers and heat pumps The standard design supports a wide variety of HFC . refrigerants such as R407C, R404A, R507, R134a. The high-pressure version is suitable for R410A and natural refrigerants (CO2 - propane). Capacity range AC120EQ / ACH120EQ cover capacities from 20 up to 200 kW. 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
