Copper Brazed Heat Exchangers

Refrigeration Line – Alfa Laval ACH Models

Alfa Laval’s ACH line of brazed plate heat exchangers specialized models developed to work in air conditioning, refrigeration, chillers and heat pump applications. They feature efficient heat transfer with a small footprint, and are commonly used as: evaporators for dry expansion and cooling water, condensers for rejecting or recovering heat in a steam/water system, and economizers for cooling liquid refrigerants or super-heating vapour refrigerants.

Additional applications include acting as sub-coolers for liquid refrigerants via well water, and intermediate heat exchanger units in absorption cycles (to pre-heat diluted solution or pre-cool concentrated solution). The ACH line has an operating capacity range of 1-1200 kW.

Media within the units flows in channels formed between the corrugated plates and corner points in an arrangement that uses counter-current flow patterns. When used as an evaporator, the evaporation process occurs within the channels; some degree of superheating is required, meaning dry expansion takes place. When used as a condenser, main components are identical to evaporator configurations, with sub-cooling occurring during process. Single-pass configurations result in all connections being located on a single side of the unit, making it easy to install.
