The VENTURA air heater, apart from the modern design, stands out mainly for it's three-pass, counter-flow-cross heat exchanger and a system of steady air distribution through the exchanger. The combination of these solutions ensures the highest efficiency in air heating compared to other devices available on the market. The heater uses a rotary ROTARY burner, which allows very good combustion parameters and low emissivity to be maintained. The entire device is convenient in use, with easy access to the exchanger and automatic ash removal system. The ash is collected in a special mobile container. This means that maintenance-free operation time of the device has been significantly extended.
