Heat exchangers
APV plate heat exchangers for district heating, refrigeration and industrial processes — from compact brazed units to large gasketed frames.
Heat exchangers: 3 lines
Gasketed plate heat exchangers
Plate heat exchangers that open up: a pack of plates and gaskets that is easy to service, extend and adapt when the process changes.
Brazed plate heat exchangers
Compact, sealed ParaBrazed exchangers in AISI 316L stainless steel brazed with copper.
Plate & shell heat exchangers
A pack of round, fully welded plates inside a cylindrical shell.
Three designs
Gasketed, brazed and plate & shell — we match the type to the medium, pressure and service needs.
Dozens of plate sizes
From small units up to DN 500 connections and 4.7 m² per plate.
Service and parts
APV plates and gaskets, including for discontinued models.
Which type to choose?
| Gasketed | Brazed | Plate & shell | |
|---|---|---|---|
| Design | can be opened, with gaskets | sealed, copper-brazed | welded plate pack in a shell |
| Working pressure | 6–30 bar | up to 30 bar | up to 40 bar |
| Working temperature | −35…+175 °C | up to 195 °C | −40…+300 °C |
| Service | cleaning, plate and gasket replacement | chemical flushing | mechanical cleaning (bolted shell) |
| Typical use | DHW, processes, marine, food | substations, refrigeration, heat pumps | high duty, aggressive media |
Specialist exchangers
For processes where a standard gasketed exchanger is not enough.
Laser-welded plate pairs
Every other channel is welded, the rest gasketed. For evaporating and condensing refrigerants (ammonia, freons) and media that must not touch a gasket.
up to 30 bar · −38…+200 °C
Double-wall plates
Two plate layers per flow plate. A leak is detected early — the media never get a chance to mix.
for gasketed exchangers
Fully welded
Heating, cooling, drying and concentrating at high temperatures and pressures — sugar, power, chemicals. Also for gases.
vacuum–60 bar · −200…+900 °C · up to 6000 m²
