Steam boilers PVR EU Series

Our boilers of the PVR EU Series, compliant with the European Directive 2014/68/EU, represent the state of the art in the field of steam boilers. They're built following the most up-to-date technological concepts and using the most advanced processing systems.


Rated pressure: from 350 to 4.000 kg/h
Rated pressure: up to 18 bar (higher rated pressure on request)
Standard efficiency: 90%
Efficiency with energy recovery systems: up to 97,5%


Unattended operation for 24/72h (for EC market)
Low emissions of NOx and CO
Connection availability for remote control with complete supervision of the boiler or the boiler room for remote monitoring and remote diagnosis
Wet back, backflame design and no refractory material to cut off maintenance costs, the loss of heat through radiation and rear tubeplate overheating.
Downwards firetube eccentricity to favour the water circulation inside the boiler and increase the steam chamber volume.
Absence of pipes in the lower part to facilitate cleaning of the water side.
Large diameter firetube to improve efficiency and observe the environment regulations in force regarding emissions.
Flanged tubeplates. Flangings absorb the body and the tube nest expansion, uniformly acting as compensators.
Large water content: the boiler has a large water content, a remarkable evaporating surface, with consequent high thermal volume and a very high steam quality.
Smoke tubes expanded only to tubeplates.
Maximum serviceability of smoke side and water side. The front smoke box is supplied with a single hinged big door to enable the complete inspection of tube nest; the rear smoke chamber is equipped with two hinged doors completely openable so to ensure easy inspection of the smoke side. The big diameter boiler body is complete with manhole and handholes doors.
High quality of the steam at every working load. In correspondence with the steam main valve, a labyrinth-type moisture separator, specially designed by us, is installed to obtain steam free of water particles and thus with a very high quality.
