Heat exchangers play a vital role in Heating, Ventilation, and Air Conditioning (HVAC) systems, contributing to efficient climate control and energy conservation. They are also gaining more and more space in distric heating branch, and that is completely justified.

Openable construction of plate and shell heat exchanger can mostly be found as good solution. Since it is possible to clean one side of heat exchanger very easy, therefore this type of heat exchanger is often used as a primary heat exchanger in systems of large boiler plants which serve to protect the boiler from pipelines  impurities.

Due to high flow rate in these cases, plate and shell heat exchangers can be produced with two separate plate packs inside one shell. Both of them can be opened and cleaned independently, which is a huge advantage when it comes to working with dirty fluids.
