Alfa Laval

AC Brazed Plate Heat Exchanger

The Alfa Laval AC is a copper-brazed plate heat exchanger built for air-conditioning and refrigeration duty, where it works as an evaporator or condenser in chillers and heat pumps. Its brazed, gasket-free construction packs high-efficiency heat transfer into an exceptionally compact footprint.

Product Benefits

No gaskets to age: The plates are sealed by brazing at every contact point rather than by gaskets, so there are no elastomer seals to age or replace.
Light and compact: The whole unit stays light and compact, so it fits into tight machine rooms and packaged chiller designs without giving up thermal performance.
Even evaporator duty: An integrated refrigerant distribution system helps the unit perform evenly when it works as an evaporator.
Refrigerant freedom: Compatibility with most HFC, HFO and natural refrigerants gives designers room to move as refrigerant regulations evolve.
Full-vacuum rated: The design is also rated for full-vacuum conditions.

Where It's Used

Air conditioning and refrigeration: The AC range is aimed squarely at these two fields.
Chillers and heat pumps: Both use the unit as the evaporator or the condenser.
Cascade systems: It also serves in cascade arrangements where two refrigeration circuits are linked.

Good to Know

Materials: Construction pairs stainless steel plates with copper brazing and stainless steel cover plates.
Connection options: External thread, internal thread and soldering are all available.
Approvals: Units carry PED and UL approvals.
Keep the water side clean: A brazed unit cannot be opened for mechanical cleaning, so the secondary circuit should stay clean and well filtered.
Selection by duty: Selection is matched to the refrigerant and the duty, so it pays to share your operating conditions when specifying.
