The Yingteng modular explosion-proof air conditioning 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 in 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 flammable and explosive areas in Zones 1 and 2. They are widely applicable in scientific research, oil, chemical, pharmaceutical, and power plant environments where IIA, IIB, T1 to T4 groups of combustible gases, steam, and air mixtures may pose explosion hazards. These combination explosion-proof air conditioning units are ideal for spaces with temperature requirements. The YingTeng combination explosion-proof air conditioning units have passed inspections by the National Quality Supervision and Inspection Center for Explosion-Proof Electrical Products and have been issued explosion-proof certificates and CCC certificates. 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 high safety reliability, making them popular 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 combination air conditioning units, and explosion-proof multi-split air conditioning units, etc.).
A new generation explosion-proof air conditioning unit with an integrated cooling source, specifically developed for modular explosion-proof air conditioning systems. It revolutionizes the traditional design concept of combining chilled water systems with modular air handling units, replacing the complex water system with a direct expansion refrigerant system. This simplifies the system structure, increases the evaporation temperature of the refrigerant, reduces construction and equipment operation costs, and is a classic example of a simple and efficient design philosophy.
Combi explosion-proof air conditioning units have wide application areas: This product is a professional explosion-proof air conditioning unit designed for purification engineering and other air conditioning projects, capable of meeting air conditioning, temperature and humidity control, dust-free, sterile, noise reduction, micro-processing programmable automatic control, easy transportation, and simple installation requirements. It effectively resolves the problems caused by different air volume and pressure head requirements in purification and air conditioning. It fully showcases the characteristics of direct expansion air conditioning while also meeting the various process requirements of the purification section, marking an innovation in purification-type explosion-proof air conditioning units. Humanized function classification: explosion-proof air conditioning units are divided into conventional and flexible types.
Standard unit, all functional sections provided by our company, including the mixing air section, pre-effectiveness section, cooling section, heating section, humidification section, medium effectiveness section, and air outlet section, etc. The cooling section is of direct expansion type, and the functional sections can be selected according to customer requirements.
Flexible type units consist of dividing the entire unit into two parts, where the customer is responsible for the pre-filtration, medium-efficiency sections of the purification air conditioning, the matching fan section, and the entire casing. Our company provides the necessary cooling and heating sources, humidifiers, and the corresponding electrical control components. Based on customer requirements, we offer types such as single cooling, heating and cooling, constant temperature and humidity, low temperature and low humidity, and 100% fresh air. Rich product series: BZ series direct expansion purification packaged explosion-proof air conditioning units, with a very diverse product line, cooling capacities of 8~340kW, air volumes of 1500~50000m³/h, suitable for a wide range of purification and other environmental air conditioning projects.

Outdoor Unit Installation
★The installation location should ensure that the hot air passing through the condenser is not re-circulated 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 be in a well-ventilated area to dissipate the hot air expelled by the unit and to draw in cooler air.
★The unit should be mounted on a sturdy and level base, which must have sufficient strength to bear the weight of the unit and the vibration during operation.
★Avoid installation in dirty or oily environments.
