Warm Air Heaters
TC-DF High efficiency warm air heaters with down air flow outlet
Oil
to 36.000
High-efficiency heater TC series "down-flow" vertical version, gas or oil-fired, providing heating of air destined to treat mainly greenhouse structures, with a ducting system where it is required
diffusion through an air distribution system on the ground.
Product informations
The appliance essentially consists of by an insulated containment casing, combustion chamber made of AISI 430 stainless steel, heat exchanger made of AISI 430 stainless steel with a flattened tubular section and turbulator imprints that optimise heat exchange.
The unit, when connected to main ducts with secondary branches, allows localised heating at the base of the plants, with significant energy savings. The centrifugal fan with variable ratio transmission makes the unit suitable for installation in plants where high static pressures are required. The generator is complete with electrical command and control equipment and a specially shaped plenum for connection to ducts.
On request, all models are available in the construction version for operation with two-stage or flame modulation burners for supply air temperature control. This also allows maximum overall system efficiency.
Construction characteristics
- Cabinet - consists of a steel sheet supporting structure, with detachable closing panels internally lined with radiation-proof heat insulation and finely epoxy-painted.
- Fan group - includes one or more centrifugal double intake fans, statically and dynamically balanced, driven through a variable gear transmission by an electric motor complete with belt tightner.
- Electric equipment - for automatic or manual fan control and for the emergency stopping of the burner in case of air overheating. Inclusive of electric switchboard and FAN-LIMIT double thermostat.
High-efficiency heat exchanger
- Combustion chamber - made of AISI 430 18% chromium INOX stainless steel, flame-inversion model with low thermal load, cylindrical or ellipsoidal, perfectly cooled in all of its points.
- Exchange elements - made of AISI 430 18% chromium INOX stainless steel plate exhaust flues, flat tubular sections, with swirl impressions for maximum thermal efficiency.
- Exhaust manifold - front and rear, made of AISI 430 18% chromium INOX stainless steel, with wide inspection doors for rational and easy cleaning.
