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 explosion hazard areas formed by mixtures of flammable gases, vapors, and air from Groups II A, II B, T1 to T4.

The "Yingteng" Series Combination Explosion-Proof Air Conditioning Units have been specially processed with explosion-proof technology, making them suitable for flammable and explosive areas in Zones 1 and 2. They are widely used in scientific research, oil, chemical, pharmaceutical, and power plant environments where IIA, IIB class T1 to T4 combustible gases, steam, and air mixtures may form explosive hazards. The combination explosion-proof air conditioning units are ideal for locations with temperature requirements. The Yingteng combination explosion-proof air conditioning units have been inspected and certified by the National Quality Supervision and Inspection Center for Explosion-Proof Electrical Products, receiving both explosion-proof certificates and explosion-proof CCC certificates. They feature an aesthetically pleasing design, reasonable construction, and ease of installation and maintenance. The full 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-type 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.).

The newly developed generation of integrated explosion-proof air conditioning units with self-contained refrigeration source, designed specifically for this purpose, revolutionizes the traditional concept of combining chilled water units with modular air handling units. It replaces the complex water system with a direct expansion refrigerant evaporation system, simplifying the system structure, enhancing the evaporation temperature of the refrigerant, and reducing both construction and operational costs. It is a classic example of a simple yet efficient design philosophy.

The Combination Explosion-proof Air Conditioning Units are widely used in various fields: This product is a professional explosion-proof air conditioning unit designed for purification projects and other air conditioning projects, capable of meeting requirements for air conditioning, temperature and humidity control, dust-free, sterile, noise reduction, micro-processor programmable automatic control, easy transportation, and simple installation. It effectively resolves the issues caused by different air volume and pressure head requirements in purification and air conditioning. It fully demonstrates the characteristics of direct expansion air conditioning while also meeting various process requirements of the purification section, representing an innovation in purification-type explosion-proof air conditioning units. Humanized Function Division: The explosion-proof air conditioning units are divided into two categories: conventional and flexible.

Standard unit, all functional sections provided by our company, including the intake and mixing air section, initial efficiency section, surface cooling section, heating section, humidification section, medium efficiency section, and exhaust air section, etc. The surface cooling section is of direct expansion type, and the functional sections can be selected according to customer requirements.

Flexible-type units involve dividing the entire unit into two parts, where the customer is responsible for the initial and medium efficiency sections of the purification air conditioning part, the matching fan section, and the entire casing, while our company provides the required cold and hot sources, humidifiers, and the corresponding electrical control components. Based on customer requirements, options include single-cooling, heating and cooling, constant temperature and humidity, low temperature and low humidity, and 100% fresh air types. Rich product series: BZ series direct expansion purification combination explosion-proof air conditioning units, with a very extensive 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 prevent hot air passing through the condenser from being re-circulated back into the unit or drawn into hot air exhausted by another unit, and there should be sufficient space for maintenance of the unit.

★There should be no obstructions in the channels for the unit's exhaust and intake air.

★The equipment arrangement should be positioned with good ventilation to carry away the heat exhausted by the equipment and draw in cooler air.

★The unit should be mounted on a base, which must be sturdy and level, and should have sufficient strength to bear the weight of the unit and vibration during operation.

★Avoid installation in dirty or oily environments.
