Alfa Laval AC220EQ / ACH220EQ
Introduction
Alfa Laval AC brazed plate heat exchangers provide efficient heat transfer with a small footprint. They are specifically designed to work in air conditioning and refrigeration as evaporators and condensers in chillers and heat pumps.
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 an integrated distributor for efficient distribution throughout the plate pack as well as a patented asymmetric plate design. The plate design provides the flexibility to select the best configuration for optimized evaporation temperature and/or condensation temperature in order to keep the brine/water pressure drop at the desired level.
Typical applications
- Evaporator and condenser in standard efficiency chillers
- Evaporator and condenser in A/W, B/W, W/W 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, R32 and natural refrigerants (CO2, propane).
Capacity range
C220EQ/ACH220EQ cover capacities from 30 kW up to 300 kW (10-80 RT). Based on standard components and a modular concept, each unit is custom-designed for each specific installation.

REFuture
A future-proof investment for tomorrow’s refrigerants
Alfa Laval gas-to-liquid heat exchangers use thin, corrugated stainless steel plates to provide heat transfer from one medium to the other. Copper brazing seals the media in the plate pack, resulting in a high-efficiency heat exchanger that consists solely of surfaces that actively contribute to heat transfer. Contact points between the plates are also brazed, which improves resistance to pressure and temperature fatigue.
The arrangement of the channels formed between the plates ensures that media flow through alternate channels in a countercurrent pattern, which further optimizes the efficiency of the heat transfer. One channel is far larger than the other channel, enabling the unit to handle very large volumetric flow rates.
