Warm Air Heaters
SMX Condensing heating sections with premix modulating gas burner
for air handling units and roof top unitsto 13.000
Condensing heating sections SMX range with premix modulating gas burner are designed to be integrated into air treatment and roof-top units.
The modulating premix gas burner allows the continuous variation of the thermal power controllable through 0-10V signal. The premix technology ensures precise regulation with perfect mixing of the combustible gas with the combustion air and guarantees hygienic combustion with very low NOx emissions (Class 5). It is possible to combine several modules in series and in parallel to achieve high power and flow rates in very compact spaces. All sections are equipped with temperature probe and safety thermostat.
On request a ductable panelled version is available for indoor or outdoor installation, equipped with casing and flange for connection to the air ducts.
Product informations
Tecnoclima premix gas suspended warm air heaters have many advantages:
- heat capacity of the premix burner has a wide modulation range: from 100 % to 30 % of the nominal heat capacity;
- thanks to the modulation of the thermal capacity, as the demand for heat from the environment decreases, very high efficiency values are reached, up to 106%, with many benefi ts in terms of environmental comfort and the reduction of gas consumption;
- the premix burner allows perfect mixing of the gas with the combustion air obtaining a semi-radiant fl ame band with very low emissions of nitrogen oxides, NOx: Class 5 of emissions;
- very high thermal effi ciency and progressive modulation of the thermal power contribute to obtain operating cost savings of over 30 % compared to traditional systems.

NOTES:
• The warm air heaters SMX are set to G20 natural gas. The conversion kit to natural gas G25 (where applicable) or propane gas G31 can be ordered separately (see accessories).
• Heating sections SMX require a power supply 230V50Hz 1N,an ON-OFF contact and a 0-10V signal for the power modulation.
