The YingTeng explosion-proof fresh air 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 from corrosive gases.

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

The "YingTeng" explosion-proof fresh air unit series has been processed with special explosion-proof technology, making it suitable for widespread use in flammable and explosive areas in Zones 1 and 2. It is ideal for scientific research, oil, chemical, pharmaceutical, and power plant environments where II A, IIB class T1 to T4 combustible gases, steam, and air mixtures may form explosive hazards. Explosion-proof fresh air units are suitable for areas with temperature requirements. The YingTeng explosion-proof fresh air units have been inspected and certified by the National Quality Supervision and Inspection Center for Explosion-Proof Electrical Products, receiving both explosion-proof and explosion-proof CCC certificates. They feature an aesthetically pleasing design, reasonable structure, and ease of installation and maintenance. The entire series is equipped with microcomputer intelligent control, digital display, low noise, stable performance, simple operation, and reliable safety, 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 new fresh air air conditioners, explosion-proof marine air conditioners, explosion-proof anti-corrosion air conditioners, explosion-proof high-temperature air conditioners, explosion-proof cold storage air conditioners, explosion-proof modular air conditioners, and explosion-proof multi-split air conditioners, etc.).

Features of Explosion-proof Fresh Air Air Conditioning Units

Enclosure

The cabinet is composed of low thermal resistance wall panels made by assembling high-sealing profile frames with color steel plates. The frame is made of 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 wall panels or glass wool wall panels can also be used. This structure is anti-rust and corrosion-resistant, aesthetically pleasing, and durable, with a low wind leakage rate of the cabinet.

Fan

Utilizing low-noise, high-efficiency outer-rotor centrifugal fans, the fans have been precision dynamically balanced, ensuring smooth operation and featuring low noise levels and higher total pressure.

Cooling Plate

The condenser core is made of seamless copper tubes and high-purity aluminum foil, which are tightly integrated through advanced mechanical or hydraulic expansion techniques. Afterward, it undergoes a 2.8MPa pressure seal leak test, meeting the performance standards of the American Refrigeration Institute (ARI). This ensures the product's superior performance and reliable quality.

Dry Condensate Trays

The meticulously 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 drainage. Additionally, the condensate pipes are sized for non-full flow, providing a discharge capacity five times greater than the unit's normal operating discharge. Timely discharge of condensate reduces the "contact time" on the trays, benefiting both in reducing corrosion and preventing bacterial growth, thereby ensuring indoor air quality.

Air Filter

Custom-designed plate filters can be easily removed from either side or top/bottom of the unit, making them particularly suitable for maintenance and cleaning in space-constrained environments. The filter media can be made of nylon embossed mesh or non-woven fabric.
