Air Heater & furnace

Keypoints in selecting Air Heater & Furnace :

Want to use heaters and forced-air furnaces as equipment to supply heat to improve the efficiency of the central heating system but you are not sure of type, capacity, brand, price, and specifications that suit your purpose? Read on to find the answers to all your questions on price, technical specifications, and the best heaters and furnaces on the market.

When the central heating system is inadequate or altogether missing, heaters or furnaces can be alternatively used for heat supply in buildings, large halls, poultry farms, greenhouses, factories, industrial sheds, workshops, galleries, banks, malls, mosques, etc.

In terms of fuel type, heaters are powered by gas, diesel fuel, bi-fuel, electricity. They also come in the form of small or larger electrical heaters. Radiant heaters are a variant of gas-powered heaters.

For places with a climate such as Tehran, Iran, each cubic meter of space requires about 40 kcal per hour of heating energy. The technicians at Damatajhiz Co. can provide you with the necessary instructions if necessary.

Air Heaters and Furnaces are categorized as fan-equipped, fan-less, and radiant types. Based on their installation, they are classified as floor-standing, cabinet heaters, or radiant heaters. The working mechanism of upright and cabinet heaters and furnaces is not significantly different, insofar that we can say they perform identically and only differ in their appearance and installation (more on this subject in the following). Nevertheless, radiant heaters that operate based on radiation heating must be mounted under the ceiling of large buildings or indoor spaces and are largely different from heating furnaces.

For heaters and furnaces, www.damatajhiz.com is the reference, most-visited website in the Middle East (since 2004, source: Alexa.com rankings). With a little patience, you can find concise, sufficient information about your desired product and purchase it at the best price (guaranteed best deal) with excellent after-sales services and a reliable guarantee.

Cabinet Heater

• As indicated by the name, cabinet heaters are manufactured in the shape of cabinets. They are mostly used in malls, mosques, banks, greenhouses, poultry farms, and other such places due to their lower height compared to the upright models.
• These heaters are powered with gas, diesel fuel, or bi-fuel.

Note: the heating value of a cubic meter of natural gas is about 9,200 kcal while the heating value of a liter of diesel fuel is about 8.500 kcal.

Advantages and features of Cabinet Heaters

• Direct air intake
• Low electricity consumption
• Proper and uniform heating
• Featuring sophisticated electrical panels
• Capable of employing ambient thermostats to accurately control the temperature

Floor-standing heaters and furnaces

Floor-standing heaters and furnaces are normally used in places such as sports facilities, industrial sheds, public places, schools, where the floor-ceiling height is large and space conservation and uniform heating are important.

Benefits and features of floor-standing Furnaces

• Proper, uniform heating
• Low electricity consumption
• Direct, damper, or channel air intake
• Sophisticated electrical panels with extra accessories
• Capable of incorporating ambient thermostats for accurate temperature control
• Ability to be equipped with air intake from the bottom of the device (reverse intake)

Radiant Heater

• As a variant of gas-powered heaters, radiant heaters transfer the flame from the burner through a u-shaped pipe in front of a heat reflector, thus reflecting heat to the surface ahead. Similar to electrical heaters, radiant heaters are only capable of hearting the surface in front of the unit through radiation, and cannot provide sustained air temperature in the environment.
• Radiant heaters are the best option to heat the desired surface in large halls or even outdoors, substantially reducing fuel consumption.
• Radiant heaters mounted 4-12 meters above ground (based on the respective capacity) warm the target surface without needing to heat the ambient air and save a great deal on gas consumption.

In general, Air Heater & Furnace are combined with three major parts: Heat exchanger, Fan, Burner

• Heat exchanger: Heat exchangers are made of steel or metal sheet of fire eater .the noise of expansion and condensation of metal in the new models of Air Heater & Furnace has been largely eliminated due to fan limite control thermostat installation .shaped metal sheets are more functional and lighter comparing to the old and cast iron heat exchanges.
• Fan: fan sucks air toward Air Heater & Furnace, bypassing over heat exchanger the temperature increase to 25-40 than conducted through rooms. most of the fans are equips with one or two-speed electromotors.
• If fan or blower fan sucks air from the heat exchanger. it is called sucking furnace and if expel air from the heat exchanger link it is called blowing or expulsion.
• In terms of security, blowing Air Heater & Furnace is preferable, because sucking furnace in case of pores existence in the heat exchanger, enters combustion products into the medium of warm air furnace installation. In sucking Air Heater & Furnace the connection of the blower fan (fan) to the electromotor is done directly or by a belt.
• Burners: Burners utilized in Air Heater & Furnaces are mainly gas, gasoline, and gas - gasoline burners .gas burners could be blower equipped or atmospheric.

Radiant Heater Applications:

• The radiant heater can be used in any place that needs to supply heat optimally with the lowest fuel consumption such as repair shops, industrial service halls, production halls, poultry houses, greenhouses flowering plants, cultivation halls of button and shelf mushrooms, manufacturing factories, sports halls, villas, swimming pools, etc. They provide natural and ideal heat for the environment.
• Furnace or hot air furnace is part of the heater which is responsible to produce warm air. The installation position of the furnace is inside of the heater with exhausted combustion air furnace or combustion chamber of Air Heater & Furnace produces heat by burning fuel and inlet cold air gets warm by passing through layers of the heat exchanger. (without mixing with combustive chamber medium.)
• The technology used in some developed (advanced) Air Heater & Furnace is not comparable with many heating machines. in advanced systems in addition to the use of the warmth of smokestack in the heater , special kind of controlling and smart security systems of fuel and oxygen are used which results in a significant reduction of pollutants.
  controlling the balance of produced heat is done by fan and burner controlling machines.

Factors which led to knowing Air Heater and furnace as safe, satisfactory, and environmentally friendly devices are as follows :

• Low carbon dioxide emission due to the complete combustion process of Air Heater & furnace.
• The combustion process in Air Heater & furnace is done by full - automated sparkless systems.
• The heat exchanger ofAir Heater & furnace doesn't produce fume in contact with floating particles.
• Combustion takes place in a heater and hot air furnace with a fully automatic system without a spark plug.
• Air Heater & furnace have a special fan for gas offloading which is connected to the smokestack to discharge combustion gases.

Safely recommendation and regulations for utilizing Air Heater & furnace :

• According to national regulation of building, installation of Air Heater & Furnace in places such as accessible corridor, fire exit corridor, meeting places, theaters, cinemas, etc. is forbidden.
• According to the national regulation of building, the distance of the Air Heater & furnace to the nearest wall needs to be at least 15 cm (6 inches) . combustible material must never be stored any closer than 30cm (12 inches) from an Air Heater or furnace.
• The accessible space in front of the device and installation distance of the burner are specified at least 45 cm (18 inches)
• Free non-ob stacked cross-sectional area of each fresh and return air channel must not be less than 4.4 square millimeters per Wat. (national regulation of building).
• Providing fresh or return air of Air Heater & furnace from the bathroom , washroom, kitchen, parking lot, and any other dangerous place is forbidden.
• Return air of an apartment must not be conveyed to another apartment by the device.

Important Tips to Know Before Choosing Heater and Hot Air Furnace:

• Determine the type and amount of fuel needed.
• Determine the amount of inlet and outlet air as well as fresh air
• Examine the amount of thermal energy loss of the desired location (wall-ceiling-floor-window) and calculate the required thermal load.
