Heissluftgebläse

The hot-air blowers are used where a large amount of warmth is required throughout the entire house for a short period of time.
Two types of hot-air blowers are available to meet the different needs of poultry growers.

Star direct fired air heater The Star direct fired air heaters are made of highgrade stainless steel, making them impervious to any unfriendly environment. The burner chamber comes in heat-resistant steel. The design of this ventilator burner guarantees excellent performance, this contributing towards an optimum indoor atmosphere at minimum heating costs. The automatic burner and ignition and photocell flame control unit guarantee a completely safe operation. The heaters always have an output of 100%. The automatic burner control is mounted in a waterproof plastic casing. A fully automatic operation is achieved by means of a thermostat or computer. The hot-air blowers are simpel to install, operate, maintain and control, and guarantee a constant and effective house temperature. There are two types of hot-air blowers: The GP-type: works with NOx (natural gas or propane) and comes in two sizes. For technical specification see table. The P-type: works with oil (kerosine 28 sec. (Redwood) or gasoil 35 sec. (Redwood)), and comes in different sizes. For technical specifica- tion see table.

Star indirect fired air heater
Specification:
The fuel and the air stream are totally separated. The exhaust gases do not go into the building as they are exhausted out through the flues.
The combustion chamber has an exclusive cylindrical design which works by flame inversion to reach high combustion temperature.

The self cleaning design of the combustion chamber gives high CO2 levels and no scat. The chamber walls retain clear giving lower maintenance requirements and clean combustion equals high combustion efficiency.

The heaters are supplied complete with electronic thermostat, two meters stainless steel flue and cap and roof plate.

The thermostat controls the fan motor either manually or automatically and will switch off the burner in case of over heating.
Heaters are either light oil (diesel) or gas (propane, LPG, methane) fired.

The burner is fixed to an insulated plate; a spy hole in pyroglass to check combustion is included.
An inspection plug, installed on the fan heater side, gives direct access to the combustion chamber and heater heat exchanger.
The heater housing is made of pre-coated galvanised pluvimag steel for protection against corrosion.
