Commercial System Plate Heat Exchangers May 05, 2019 Commercial System Plate Heat Exchangers. Plate heat exchangers are designed to separate the system water from the boiler. Fitting a plate heat exchanger is the ideal solution where it is difficult to guarantee system cleanliness and therefore water quality through the boiler. It is suitable for older applications where the systems cannot be pressurised. By separating the boiler from the system, the integrity of the boiler is maintained and it can operate as a pressurised system whilst still allowing the boiler to operate on an existing open-vented system. Care must be taken to ensure that the system water circulating through the plate is filtered and treated accordingly. Using a plate heat exchanger will protect the boiler and minimise possible down time whilst maintaining the boiler at its highest efficiency throughout its life span. It is mandatory to install a plate heat exchanger on some boilers and cascade systems.
