In some large industrial buildings, heating has always been a key issue. Traditional convection heating methods, such as radiators or warm air fans, face many challenges in high spaces. Due to the high ceilings, the heat loss caused by cold air infiltration through the envelope is huge. Using a large number of radiators not only incurs high costs but also fails to provide satisfactory heating effects. Although warm air heating is also applied, it still has the problem of serious energy waste. Its convection heat transfer method leads to a large amount of energy being consumed in heating the ineffective space. Moreover, to achieve good air distribution, complex ventilation ducts and a large number of air treatment devices are required, which occupy valuable space.&nbsp;


	 


	The emergence of gas infrared radiation heating has brought a new solution to the heating of large spaces. According to GB50019-2015, the Design Code for Heating, Ventilation and Air Conditioning of Industrial Buildings, when gas infrared radiation heating is adopted, the indoor design temperature should be 2℃ to 3℃ lower than that of convective heating. This feature has many advantages. On the one hand, it reduces the temperature difference between indoors and outdoors and decreases the infiltration of cold air. On the other hand, it effectively reduces air stratification and convective effects. In traditional convective heating, indoor air forms a cold and hot convection, resulting in a significant temperature gradient, with high temperatures at the roof and low temperatures at the ground, and a large amount of heat is lost in the upper part of the space. However, in gas infrared radiation heating, heat is directly radiated to the heating objects, and the ground can accumulate some heat. The indoor air temperature gradient is small, and the heat loss at the upper part of the building is significantly reduced, greatly improving the thermal energy utilization rate of the heating system. Compared with convective heating, it can save 30-50% of energy.&nbsp;

	IMPRESIND gas radiant heating system has performed outstandingly in this field and has been widely applied. The system consists of a generator, a radiant section and a control system. The generator burns natural gas, and the resulting hot fluid flows in the radiation tubes made of aluminum alloy steel under the drive of a negative pressure centrifugal fan, generating infrared rays and precisely applying radiant heat to objects and people in the heating area. The system also has a built-in flue gas recirculation device, which recovers up to 70% of the residual heat from the flue gas, not only improving the heating efficiency but also reducing the flue gas temperature and the formation of nitrogen oxides, achieving a balance between energy conservation and environmental protection.&nbsp;


	 


	IMPRESIND gas radiant heating system is highly flexible in operation. Each set of equipment can operate independently and be managed through a single control panel or a centralized system. Users can control the temperature by time and zone according to their needs, easily setting various operation modes such as comfortable and economical, night duty, and holidays, ensuring that every degree of heat is released as needed. While guaranteeing comfort, it maximizes energy savings. Its modular design makes it highly adaptable. Whether it is a large industrial plant, a logistics warehouse, or a complex space like an aircraft maintenance hangar with a ceiling height of 30 meters, the radiant tubes can be flexibly spliced in lengths of 2 to 6 meters, and the installation methods can be adjusted in multiple dimensions. It is like a tailor-made solution for various large industrial buildings, precisely meeting the heating needs of every inch of space.&nbsp;


	 

At present, IMPRESIND gas radiant heating system has been successfully applied in many key projects. In the No. 1 Hangar of China Southern Airlines at Beijing Daxing Airport, IMPRESIND system has enabled efficient and stable heating, meeting the strict space heating requirements. In the heating renovation project of the China Southern Airlines maintenance hangar at Urumqi Airport, the introduction of IMPRESIND system has led to significant energy savings and improved heating comfort. Projects such as the freight warehouse of the Ordos Comprehensive Bonded Zone, the Coca-Cola beverage processing plant in Heilongjiang, and the logistics warehouse of the China Post Langfang Mail Processing Center have all relied on IMPRESIND gas radiant heating system to solve the heating problems of large spaces. With its advantages of precise temperature control, high energy efficiency, and scene adaptability, it has become the top choice for industrial heating in large spaces.
