VIMAR - Model Vigas 25 TVZ -Hot Air Boiler
The hot air boiler VIGAS TVZ is designed for burning dry wood from sawdust to logs up to 35 cm long. Sawdust, shavings, chips and offcuts must be burned together with larger logs. The contents of the hopper are sufficient for 6-10 hours of normal boiler operation. The boiler is welded from 4 and 6 mm thick steel sheets. The inner casing of the boilers, which is in contact with the flue gas, is made of sheet metal with a thickness of 6 mm and treated with an anti-corrosion spray. The heat exchanger is welded steel pipes Ø57×4.5 mm. The space of the combustion chamber is lined with fireclay bricks 20 mm thick. The cover shell is made of sheet metal with a thickness of 0.8 mm. The insulation of the boiler consists of NOBASIL material with a thickness of 20 and 40 mm.
Management
Electronic regulation AK 4000 is a new control unit for VIGAS boilers. It meets the requirements for easy operation. Already in the basic version, it is possible to connect a room temperature controller or an exhaust fan. It enables time and temperature regulation of the boiler with a weekly program. It indicates fuel burnout, fuel control or malfunction with its description. In the process of gasification and burning of fuel, the AK 4000 electronic control monitors the change in temperature and, as necessary, smoothly increases or decreases the speed of the blower fan.
Utilization
The main area of use of hot air heating is industrial buildings (halls) and drying rooms.
Advantages
The advantage of hot air heating is great operational readiness and heating can be easily combined with ventilation.
