Four hooks (two on each side) make iteasy to hang the heater close to the area where heating is required.The heater works on the principle of indirect combustion, which ensuresclean operation and prevents any emission of exhaust gas into the heatedenvironment. The GP heater can burn wide range of fuels such as diesel,natural gas, LPG or propane (paraffin upon request). It is supplied fullyassembled and ready for installation. The standard product line encompassesa range of small sizes with nominal heating efficiencies around 90%.Technology basisThe GP Air Heater works on a principle of indirect combustion. A heatexchanger is used to separate the combustion process from the heated airstream, which allows for combustion gases to exit the building through achimney. A powerful fan forces room air at high pressure over the heatexchanger where the air absorbs heat from the combustion process. Thewarm and dry air is then supplied into the room through the air outlet. Thestandard type of air outlet has an elliptical design suitable for installation ofa plastic duct for an optimal distribution of the warm air throughout thedesired indoor area.

DesignCombustion chamber and heat exchanger:the combustion chamber is made from stainlesssteel. It has a special cylindrical shape allowinggood flame reversal in order to reach highcombustion temperatures and very efficient heatexchange. Both the combustion chamber and theheat exchanger have been designed to reach highthermal efficiency and extended service life of theheater.Axial fan: the direct driven axial fan is equippedwith round safety mesh.Radial fan: radial fan is belt driven and equippedwith protection mesh. It ensures high pressureoutput and low noise levels.Housing: housing is made of pre-coatedgalvanized steel in order to prevent corrosion andenable easy cleaning.Burner: high efficiency has been the mainpriority in the design of the heater. Each heateris equipped with a stand-alone, high qualityburner, which assures an excellent combustion,stable performance and extremely safe operatingconditions (See the table beside).Operation and regulationThe GP heater is also equipped with programmabledigital room thermostat and remote temperaturesensor for stand alone use. This allows the userto measure the temperature in the most criticalpoints and to operate the heater accordingly. Incase of climate controlled indoor environment,the GP heater must be driven by the output relayfrom the climate controller. In order to increasethe safety and to avoid instable operation, there isa dual switching mechanical thermostat mountedon the heater. The thermostat activates the fanmotor based on the temperature measured on thecombustion chamber and on the heat exchanger.In case of fan malfunction it stops the burnerand the fuel flow immediately. A pyroglass eyeinstalled on the heater’s housing makes it easy toinspect the flame inside the combustion chamber.For operations in the dusty environments it isrecommended to use a supplementary flexiblepipe to supply fresh and clean air from outsideinto the burner.APrinciple illustration:A: Cool ambient airB: Combustion chamberC: Hot exhaust gasD: Heat exchangerE: Exhaust gasF: Warm and dry air entering the greenhouseG: BurnerHeatersizeGP30GP50Diesel Diesel Gas Gas TotalthermalFinterm Burner[kW]*AZ4[37]AZ8[67]* Maximum power with the installed nozzle.CBRiello Burner[kW]*RG01 Gulliver[37]RG2 Gulliver[67]EDFinterm Burner[kW]JM6gas[37]JM9gas[66]Riello Burner[kW]40 FS5R MB 03/1[37]40 FS8R MB 05/1[58]Gpower[kW]3460FInstallation and maintenanceGP is equipped with four hooks (two on eachside). Thus it can be easily hung over the area thatrequires heating. The standard supply contains 2stainless steel exhaust pipes (each 1 meter long);stainless steel chimney; a big size stainless steelroof pass plate for easy installation in structuresmade from plastic film and a digital roomthermostat. The combustion chamber can be easilycleaned with pressurised water (with or withoutdetergents) through a built-in service port. Chainsand wires for hanging the heater are not includedin the supply. It is generally recommended that ajet-fan is installed in conjunction with each heateroutlet.
