- The Unimat UT-HZ hot water boiler is a shell boiler in 3-pass design with two completely separate flame tubes and flue gas passages. This double-flame tube/smoke tube boiler has been in use for decades and is built with separate flue gas passages. This means it is suitable for operation with just one burner.
- The UNIMAT UT-HZ hot water boiler is deployed in all areas where very large amounts of heat are required. The main areas of use are district heating generation and the processing industry.
