Hot over- and underpressure winds are blowing
The traditional Antti Vulcan heater models can be equipped with both light oil and gas burners. All models in the Vulcan range are available in both Hipress overpressure and Vacboost underpressure versions. They come with a combustion chamber and heat exchanger made of fireproof stainless steel.
Our heaters have a maximum drying temperature of 100°C and offer outstanding efficiency (92–95%). The high drying temperatures result in energy savings of up to 30%.

Vacboost heaters with gas burner
Vacboost heaters are efficient and economical heaters for the grain dryer. They work on an underpressure principle with direct burning, so the flue gases do not deteriorate the efficiency. The heaters have been equipped with a modulating burner, which uses natural or liquid gas as fuel. They have enough power for even demanding use.
