The Yingteng explosion-proof air handling unit can operate normally under the following environmental conditions:

a) Altitude not exceeding 2,000m

b) Suitable for environments with temperatures ranging from -7℃ to 43℃, free of corrosive gases.

c) There are explosion hazard areas formed by mixtures of flammable gases, vapors, and air from Groups II A, II B, and T1 to T4.

The "YingTeng" explosion-proof fresh air unit series has been specially processed with explosion-proof technology, making it suitable for use in flammable and explosive areas in Zones 1 and 2. It is widely applicable in scientific research, oil, chemical, pharmaceutical, and power plant environments where there may be or could be IIa, Iib Group T1 to T4 combustible gases, steam, and air mixtures that pose an explosion hazard. Explosion-proof fresh air units are suitable for locations with temperature requirements. The YingTeng explosion-proof fresh air units have been inspected and certified by the National Supervision and Inspection Center for Quality of Explosion-Proof Electrical Products, receiving both explosion-proof certification and explosion-proof CCC certification. They feature an aesthetically pleasing design, reasonable structure, and ease of installation and maintenance. The full series of explosion-proof fresh air units are equipped with microcomputer intelligent control, digital display, low noise, stable performance, simple operation, and high safety reliability, making them highly favored in the market. (Customizable options include explosion-proof window-type air conditioners, explosion-proof duct-type air conditioners, explosion-proof ceiling-mounted air conditioners, explosion-proof fresh air air conditioners, explosion-proof marine air conditioners, explosion-proof corrosion-resistant air conditioners, explosion-proof high-temperature air conditioners, explosion-proof cold storage air conditioners, explosion-proof modular air conditioning units, and explosion-proof multi-split air conditioning units, etc.).

The YingTeng新风空调 unit has been developed with years of professional manufacturing experience, integrating the strengths of various renowned domestic and international products, to meet user needs and achieve advanced domestic air conditioning technology. It offers a range of functions including heating, cooling, humidifying, and filtration purification of air. Widely used in comfort air conditioning for large and medium-sized public buildings such as hotels, shopping malls, airports, hospitals, and office buildings, as well as process air conditioning in industries like electronics, textiles, chemicals, pharmaceuticals, and food processing.

The YingTeng explosion-proof fresh air air conditioning unit not only boasts superior cooling and heating performance, low noise, slim height, compact structure, light weight, and easy installation and maintenance, but also, when equipped with a variable frequency or variable pressure speed controller, can operate with variable air volume for energy-saving purposes, tailored to the different seasons and conditions of the on-site air conditioning environment. Thus, it is particularly suitable for use in various air conditioning engineering scenarios in buildings with compact layouts.

Features of Explosion-proof Fresh Air Air Conditioning Unit

Casing

The cabinet is constructed with a combination of low thermal resistance wall panels made from high-sealed profile frames and color steel plates. The frame is made of an aluminum alloy profile skeleton: the wall panels are made of polyurethane integral foam with a thermal conductivity of: λ=0.022 W/m·K. High-density polyethylene or glass wool wall panels can also be used. This structure is resistant to rust and corrosion, aesthetically pleasing, and durable with a low air leakage rate.

Fan

Utilizing low-noise, high-efficiency external rotor centrifugal fans, the fans are precision dynamically balanced to ensure smooth operation of the unit, featuring low noise and high total pressure.

Cooling Coil

The evaporator core is made of seamless copper tubes and high-purity aluminum foil, which are tightly integrated through advanced mechanical or hydraulic expansion techniques. Afterward, they undergo a 2.8MPa air pressure sealing leak test, meeting the American ARI standards. This ensures the product's superior performance and reliable quality.

Dry Condensate Pan

Carefully designed condensate trays and extra-thick insulation materials ensure that the unit operates without condensation or dripping in harsh environmental conditions. The condensate trays are slightly inclined for efficient condensate drainage. Additionally, the condensate pipes are sized for non-full flow, providing a discharge capacity over five times the normal operating discharge. Prompt discharge of condensate reduces the "contact time" of the tray, benefiting both corrosion reduction and preventing bacterial growth, thereby ensuring indoor air quality.

Air Filter

Specially designed panel filters can be easily removed from either side or above the unit, making them particularly suitable for maintenance and cleaning in space-constrained environments. The filter material can be nylon embossed mesh or non-woven fabric.
