The Yiting 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 of corrosive gases.

c) There are explosive 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 II A, II B, T1 to T4 groups of combustible gases, steam, and air mixtures that pose explosion hazards. 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 Explosion-Proof Electrical Product Quality Supervision and Inspection Center, receiving both explosion-proof certification and explosion-proof CCC certification. They feature an aesthetically pleasing design, reasonable structure, and are easy to install and maintain. The full series of explosion-proof fresh air units are equipped with microcomputer intelligent control, digital display, low noise, stable performance, simple operation, and are safe and reliable, making them highly favored in the market.

YingTeng新风空调 units have been developed with years of professional manufacturing experience, integrating the strengths of both domestic and international top products to meet user needs. These units represent advanced domestic technology and can perform a variety of functions, including heating, cooling, humidifying, and air filtration and purification. They are widely used in comfort cooling systems for large and medium-sized public buildings such as hotels, shopping malls, airports, hospitals, and office buildings, as well as in process cooling systems for industries such as electronics, textiles, chemicals, pharmaceuticals, and food processing.

The YingTeng explosion-proof fresh air air conditioning unit boasts superior cooling and heating performance, low noise, thin height, compact structure, light weight, and easy installation and maintenance. Moreover, equipped with a frequency or pressure variable speed controller, it can operate with variable air volume for energy-saving purposes, matching different seasonal conditions and on-site air conditioning environments. Therefore, it is particularly suitable for use in various air conditioning projects with compact buildings.

Features of Explosion-proof Fresh Air Air Conditioning Unit

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

Cooling Plate

The condenser core is made of seamless copper tubes and high purity aluminum foil, sealed tightly together through advanced mechanical or hydraulic expansion techniques. It then undergoes a 2.8MPa pressure seal leak test, meeting the performance standards of the U.S. ARI, ensuring the product's superior performance and reliable quality.

Dry-type condensate tray

Precision-engineered condensate trays and extra-thick thermal insulation ensure that the unit operates without condensation or dripping in harsh environmental conditions. The condensate trays are slightly tilted for improved condensate 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 removal of condensate reduces the "contact time" of the condensate tray, benefiting both in reducing corrosion and preventing bacterial growth, thus 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 corrugated mesh or non-woven fabric.
