The first heat exchanger stage uses 45ºF chilled water to cool and dehumidify the 2,280 SCFM, 4 PSIG air flow from 145ºF to 55ºF. The air, then at 100% RH passes through a mist eliminator to ensure no condensate droplets carry downstream. The second heat exchanger stage uses steam to heat air back to 95ºF, where it is at 23% RH.
The inspector with evaluate the overall condition of the furnace and control systems. Of all the major heating systems (Steam, Hot Water, Warm Air), warm air heating systems pose the greatest hazard. When the heat exchanger of a warm air furnace is cracked or leaking it can leak carbon monoxide gas into the living area. UNIT HEATERS -WARM AIR INDUSTRIAL UNIT HEATERSThe heating hot water or steam from your boiler flows through a radiator heating coil, there an electric fan forces air through the radiator coil ( this is why these unit heaters are sometimes referred to as a forced air unit heater) ,the air passing over the heat exchanger absorbs the heat from the hot water or steam, that is feeding the
NC90 Hot Water Stream Air Fan Blower Heater with SRL Exchanger. · NC series industrial air fan heater consists of axial motor (s), high efficient heat exchanger and patent outer cover. · Taking steel tubes with aluminum foil as heat exchanger, the durable pressure is 0.6 MPa. High Precision and Electric heat exchanger blower Aug 13, 2021 · High Precision and Electric heat exchanger blower
Jul 06, 2001 · These self-contained heating devices are fueled by gas, oil, electricity, steam, or hot water ( Fig. 1). Each unit has a heat exchanger and air-moving fan or blower to deliver heated air to a space. They are individually suspended over the area to be heated. Unit heaters are usually spaced evenly to give good air coverage with their air patterns complimenting each other.
