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" Series Combination Explosion-Proof Air Conditioning Units have been specially processed with explosion-proof technology, making them suitable for use in Class 1 and 2 flammable and explosive environments. They are widely employed in research, oil, chemical, pharmaceutical, and power plant settings where IIA, IIB level T1 to T4 combustible gases, steam, and air mixtures may pose explosion hazards. These combination explosion-proof air conditioning units are ideal for areas requiring temperature control. The YingTeng series has passed inspections by the National Center for Supervision and Inspection of Quality of Explosion-Proof Electrical Products and has been awarded explosion-proof certificates and CCC certificates. They feature an aesthetically pleasing design, reasonable construction, and ease of installation and maintenance. The entire series utilizes branded compressors, microcomputer intelligent control, digital displays, and boasts low noise, stable performance, simple operation, and reliability, earning them popularity in the market. (Customizable options include explosion-proof window-type air conditioners, explosion-proof duct-type air conditioners, explosion-proof ceiling-type air conditioners, explosion-proof 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 combination air conditioning units, and explosion-proof multi-split air conditioning units, etc.).
A new generation explosion-proof air conditioning unit with built-in refrigerant source, specifically developed for modular explosion-proof air conditioning systems. It revolutionizes the traditional design concept of chillers combined with modular air handling units, replacing the complex water system with a direct expansion refrigerant system. This simplifies the system composition, enhances the evaporation temperature of the refrigerant, reduces construction and equipment operation costs, and is a classic representation of the minimalist and efficient design philosophy.

Outdoor Unit Installation
★The installation location should ensure that the hot air passing through the condenser is not recirculated back into the unit or drawn into the exhaust air of another unit, and there should be sufficient space for maintenance of the equipment.
★There should be no obstructions in the channels for the unit's exhaust and intake air.
★The unit arrangement should have good ventilation to carry away the hot air blown out by the unit and to draw in cooler air.
★The unit should be mounted on a sturdy and level base, which must be strong enough to support the unit's weight and vibration during operation.
★Avoid installation in dirty or oily environments.
