DamaTajhiz industrial/commercial water heaters are the best economical option for supplying hot water to high-use places such as public bathrooms, car washes, construction and manufacturing workshops, etc. As they are made with galvanized sheets with appropriate thickness and quality.
The following content provides the technical specifications, sales terms, capacity determination, and the price of all models of DamaTajhiz commercial water heaters.
Industrial water heaters are heat transfer equipment and instant hot water supply for consumption, and in terms of heat transfer, they have a simple structure similar to a hot water boiler or other heat transfer equipment and heat exchangers.
DamaTajhiz HVAC has been manufacturing and supplying all types of commercial water heaters with the best quality and appropriate or fast delivery time since 2004 in the Middle East and West Asia.

DamaTajhiz commercial water heaters consist of 4 main components:
The body of the DamaTajhiz commercial water heater is made of a hot galvanized steel sheet with a thickness corresponding to their capacity, from 4 to 8 mm. The welded areas are covered with sanitary and safe epoxy paint on both sides; The color is usually white or blue but custom colors are also available.
The thickness of the sheet DamaTajhiz horizontal commercial water heaters is equal in all areas. However, in vertical models, the thickness of the dishes is considered greater than the body, due to the pressure applied to the upper and lower dishes of the tank, especially the lower dish,
Dematheiz industrial water heaters have handholes in smaller capacities and manholes in high capacities for inspection and possible repairs.
There are 8 plumbing connections installed to the body of the industrial water heaters:
Notes:
DamaTajhiz commercial water heaters have the ability to install a fanned burner or an electric heating element which are of gas or diesel, dual-fuel, diesel or electric types with appropriate capacity and in different models, and you can order water heaters with or without a burner according to your need.
DamaTajhiz water heaters are usually equipped with Iran-Radiator and Garm-Iran burner types, which can be changed according to the customers' orders.
Note: Burner installation equipment and accessories, such as hoses, gas filters, diesel nozzles, diesel filters, etc. must be purchased separately.
DamaTajhiz commercial water heater furnaces are designed, manufactured, and supplied from 4, 6, and 8-inch firetubes based on their capacity (two-pass in horizontal models and one-pass in vertical models).
To control the temperature of the outlet water of the DamaTajhiz commercial water heaters it is necessary to use two submerged thermostats that are installed in series in the circuit.
The first thermostat performs the role of initial disconnection and connection, and the second thermostat is at a temperature of 10 degrees higher. It is set as a limit thermostat that will operate and turn off the burner if the first thermostat does not work.
To display the temperature inside the outlet water source in the highest part of the water heater, use a temperature gauge that is sheathed from 0 to 120 degrees Celsius.
Also, to prevent possible pressure increases inside the tank, it is necessary to use a standard and efficient temperature and pressure safety valve according to the regulations and technical instructions.
Note: Regarding the installation of burners, it is strongly recommended to use a pressure-relief valve instead of a safety valve, so if for any reason, the temperature and finally the pressure inside the source exceeds the permissible limits, the pressure-relief valve (which is more functional than regular safety valves) can discharge excess pressure and prevent any accidents.
Extra: The order for the preparation and installation of the pressure relief valve can be done at the request and expense of the respected buyer.
If the distance between the consumer and the industrial water heater is large is necessary to implement the return water pipe during plumbing so that the consumer doesn't have to wait for the hot water and to reduce the waste of water.
Returning water to the water heater is usually done by a small 1-inch linear pump, which is calculated according to the length of the route, the number of consumers, and the system's capacity.
