Product introduction

 

 

Velit 4000P air heater is consisted of a drive unit (combustion air fan, 
heating air fan and drive motor), heat exchanger, burner with 
combustion chamber, control unit, glow plug and housing. The ignition 
and fuel supply are automatically controlled by the control unit. After 
starting up, fuel will be pumped into the combustion chamber and 
ignited by the glow plug. Meanwhile the heating air fan pulls the indoor 
cold air into the heat exchange channel. The air will be heated up by the 
heat exchanger and then pushed into the cabin area.
