The "YingTeng" explosion-proof air conditioning series has been processed with special explosion-proof technology, making it suitable for use in flammable and explosive areas in Zones 1 and 2. It is widely applicable in 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. Explosion-proof air conditioners are suitable for locations with temperature requirements. The YingTeng explosion-proof air conditioners have been inspected and certified by the National Explosion-Proof Electrical Product Quality Supervision and Inspection Center with explosion-proof certificates and CCC certificates. They feature an aesthetically pleasing design, reasonable structure, and ease of installation and maintenance. The entire series uses 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 modular air conditioners, and explosion-proof multi-split air conditioners, etc.).

Roof-mounted explosion-proof air conditioning units are all-air systems designed for indoor air treatment, integrating cooling, heating, dehumidification, humidification, ventilation, and air purification functions into medium to large-scale air conditioning equipment. This product combines modular air handling units with direct expansion air conditioning technology, enabling centralized comprehensive control of cooling and air conditioning. It features high efficiency and energy saving, simple system, stable performance, compact structure, high control accuracy, safety and reliability, low noise, high static pressure, minimal vibration, high corrosion resistance, good sealing, excellent rain and dust protection, easy installation, and attractive appearance. The microcomputer control ensures the product's performance and quality are fully demonstrated and utilized.

The unit is divided into two sections: the compression and condensation section, and the air handling section. The compression and condensation section is assembled in a modular manner, while the air handling section features a modular design by function. The outer shell is constructed with a cold-bridge-free aluminum alloy frame and a polyurethane sandwich panel with double-sided steel plates. The unit offers flexible and diverse combinations, is easy to install, and can be placed on rooftops or outdoor open spaces without the need for a dedicated machine room. The product is suitable for large industrial sites such as factories and workshops with limited water access or in water-scarce areas, as well as for full-air conditioning systems in comfort-oriented locations such as hospitals, malls, supermarkets, restaurants, and office buildings.

Roof-mounted Explosion-proof Air Conditioning Unit Product Features

1. Comprehensive variety and specifications: Roof-mounted air conditioning units are divided into three series based on function – Cold Air Type (L), Heat Pump Type (R), and恒温恒湿Type (H). The恒温恒湿Type is suitable for process air conditioning environments with high requirements for temperature and humidity control, while the Cold Air Type and Heat Pump Type are ideal for comfort air conditioning applications.

Products are available for custom production with cooling capacities ranging from 12kW to 490kW, catering to different high air volume and space air conditioning requirements.

Products are divided into series such as standard, purification, and 100% outside air, offering optional functional sections for easy realization of cooling, heating, dehumidification, humidification, air purification, noise reduction, and energy-saving fresh air functions.

2. No dedicated machine room required, saving on investment: The series of units have been treated for corrosion and rain resistance, allowing the entire unit to be placed on the roof or outdoor space, eliminating the need for a machine room and saving on building space and construction investment costs: The units are all-air systems, without chilled water or cooling water systems, thus saving on auxiliary equipment such as chilled water pumps, cooling water pumps, cooling towers, fan coils, and piping.

Investment readiness has reduced the construction cost. 3. Convenient transportation and easy installation: The unit design features two structural types: Standard and Purification models. The Standard model, with a cooling capacity of 140kW or below, is designed as an integrated structure, while above 140kW, it is a split structure, facilitating transportation and installation. The Purification model is modularly designed, with customizable functional sections, simple configuration, and flexible variety. The volume of each functional section

Small, lightweight, and customizable to fit on-site conditions, easy to transport and install. 4. Cold bridge-free frame, low air leakage rate: The air treatment sections use cold bridge-free aluminum alloy frames, with panels made of polyurethane high-pressure foam insulated boards (outer panel: electrostatically sprayed steel plate, inner panel: galvanized steel plate). The frame and panels are equipped with special sealing and insulating strips, as well as a unique outdoor rainproof structure design, ensuring the unit operates outdoors effectively.

With required corrosion and rust resistance, vibrant colors, and aesthetic appeal. 5. The unit employs a brand-name fully enclosed scroll compressor, ensuring smooth operation, reliable performance, and high refrigeration efficiency: According to customer requirements, non-standard heat recovery units can also be provided for energy-saving and environmental protection.

6. Equipped with a direct-drive low-noise axial fan and a rear-tilted centrifugal blower, effective vibration isolation measures are in place to ensure smooth and reliable operation of the unit with low noise and minimal vibration.

7. A wide range of refrigeration accessories and control components are from international renowned brands, featuring high system reliability and stable performance.

8. Both the evaporator and condenser are copper-tube aluminum-fin heat exchangers, designed with computer optimization and manufactured on a dedicated heat exchanger production line, ensuring high efficiency and energy saving.

9. Standard units are equipped with intelligent instrument control, and industrial-grade programmable logic controllers (PLC) can be optionally selected according to customer requirements. Standard purification units come with industrial-grade PLC control, operating under optimized programs. They also feature fault self-diagnosis and alarm functions. The controller is equipped with a standard RS485 communication interface, allowing for convenient remote control from a different location or connection to an intelligent control system, ensuring optimal equipment operation and reduced operating costs.

10. The air handling unit can be equipped with horizontal supply air, side supply air on either side of the unit, upward supply air, and downward supply air, etc., which is particularly suitable for the renovation of air conditioning systems in old buildings (simply lead the original supply and return air ducts to the roof to connect the main unit): Additionally, replacing the main unit that has reached the end of its service life is also convenient, alleviating any concerns for the user.

11. The units can be treated for explosion-proof and corrosion resistance according to specific requirements of the application. They are widely used in industries such as petrochemicals, metallurgy, pharmaceuticals, and more. The explosion-proof marking for the units is ExdbebibmbllBT4Gb. There are also products with the explosion-proof marking ExdbebibmbllcT4Gb. Please consult and confirm with our technical department before placing an order.
