Condensing boilers (class A · integrated blue-flame burner) and separate oil burners
Intercal combines class A condensing boilers with an integrated blue-flame burner and separate oil burners — all focused on top fuel efficiency. On this microsite the focus is on marine, offshore, process and projects, where every litre should deliver as much heat as possible; for UK sales please contact your local distributor. The solutions run fossil-free on HVO.
Top efficiency also matters for coastal plants and offshore, where clean, renewable fuel is a good fit.
Key points:
- Class A condensing boilers with integrated blue-flame burner
- Separate oil burners (BNR blue-flame, SLV/SL)
- Top fuel efficiency — most heat per litre
- Fossil-free on HVO/bio-oil
- For process, offshore and projects
