Features
OEM-PRO vessels are membrane expansion tanks. Thanks to the wide range of vessels (shapes, capacity, connection and attachment systems) of the OEM-PRO system makes it easy to match the specific requirements of boiler manufacturers. It is a matter of fact that brackets can be added on demand following the requests of customers. To help ensure a long, high performance life, every vessels is factory tested and manufactured using rubbers conforming to DIN-4807-3. The vessels are also painted with long-lasting external grade epoxy-polyester powder coating.
The range includes high quality and compact expansion vessels for the sanitary circuits of boilers (capacities from 2 lt. to 4 lt.).
