The YingTeng explosion-proof industrial air conditioner 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 in Group II A, II B, T1 to T4.
The "YingTeng" explosion-proof industrial air conditioning series models have been specially processed with explosion-proof technology, making them suitable for use in flammable and explosive areas classified as Zones 1 and 2. They are widely applied in research, oil, chemical, pharmaceutical, and power plant environments where there is or may be a risk of IIA, IIB Group T1 to T4 flammable gases, steam-air mixtures, and explosion hazards. Explosion-proof industrial air conditioners are ideal for locations with specific temperature requirements. These 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 engineering, and ease of installation and maintenance. The entire series utilizes brand-name compressors, microcomputer intelligent control, digital display, and boasts low noise, stable performance, simple operation, and safety. They are 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 conditioners, and explosion-proof multi-split air conditioners, etc.).

Diverse in form and function
Explosion-proof industrial air conditioners are categorized into three main types: direct air supply, top air supply with front return, and top air supply with rear return. To meet the requirements of different working environments or functional needs of specific application sites, there are various derivatives available, including heat pump models, heat pump electric auxiliary heating models, cold air electric heating models, cold air hot water coil models, 100% fresh air models, and single cooling models. The wide range of types and capacities can satisfy the air conditioning needs of various commercial spaces and industrial special applications.
Direct Air Delivery
Direct-airflow models utilize bidirectional louvered blowers, offering long throw distance and high air volume. They feature compact size, attractive appearance, and simple, flexible application, reducing the amount of renovation and installation work for users. Suitable for local air conditioning in medium and small spaces.
Top blowing type
The top-airflow model utilizes ducted air distribution for ventilation. Users can flexibly choose the ventilation method and reasonably arrange the number of air outlets based on the space conditions and requirements, meeting the needs of centralized management and balanced temperature control in large spaces. The exhaust air methods include front-exhaust type, suitable for direct exhaust in independent large spaces without the need for exhaust ducts or machine rooms; and rear-exhaust type, suitable for centralized air conditioning of exhaust air in multiple independent spaces, requiring the setup of exhaust air ducts and machine rooms for each space.
Advanced performance
The product features an efficient centrifugal compressor, a flat heat expansion valve from an international brand, a high-performance heat exchanger meticulously designed and manufactured, and the unit has been meticulously tested by an authorized CNAS-certified testing center.
