Plate Type Heat Exchanges
Plate-type heat exchangers are characterized by their long period of operation and easy execution of routine maintenance.
The service life of the first unit being out of service – joint packing – is up to 10 years. Operating term of fins is 20-25 years. The cost of replacement seals is in the range of 15-25% of the cost of plate-type heat exchanger, that is more economically of the similar process of replacing the brass tube block in shell-and-tube exchanger, that is 80-90% of the cost of unit.
