Alfa Laval - Plate Heat Exchanger
AC70X / ACH70X 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 a patented distributor integrated in the plate design.

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
AC70X/ACH70X cover capacities from 10 up to 80 kW for chillers and 5 kW to 40 kW for heat pumps. Based on standard components and a modular concept, each unit is custom-designed for each specific installation.
