Ontop Metaloterm offers a wide range of flue gas systems for large boilers (condensing/dry, positive pressure/negative pressure, cascade and CLV installations) in non-residential buildings and also exhausts for steam boilers in production processes that are heat and pressure resistant.
The Metaloterm MF, ME and UE systems are particularly suited for these applications with various advantages, such as sealing rings for condensation and pressure-tight sealing. Ontop Metaloterm also supply EPDM and Viton rings for relevant installations.
Ontop Metaloterm also offer a wide range of reducing Tees that allow for the connection of different devices to a single pipe. Ontop Metaloterm Specialists can take care of diameter and back pressure calculations. In addition, calculation software is available on our website.
Noise can have a major impact on comfort, so for our systems we have innovative silencers that substantially reduce the noise. For Marine and Offshore, the Ontop Metaloterm AD/AM type is
approved by ABS, DNV GL, Bureau Veritas, Lloyd’s Register and PRS for use of super-yachts, cruise ships, platform supply vessels, tow boats, etc.
