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 with functional sections. The housing is constructed with a cold-bridge-free aluminum alloy frame and a polyurethane sandwich panel structure with double-sided steel plates. The unit's assembly methods are versatile and easy to install, suitable for placement on rooftops or outdoor open spaces without the need for a dedicated machine room. The product is ideal for large industrial sites such as factories and workshops in areas with limited water access or scarce water resources, as well as for full-air conditioning systems in comfort-oriented locations such as hospitals, shopping malls, supermarkets, restaurants, and office buildings.

Roof-mounted Explosion-proof Air Conditioning Unit Product Features

1. Comprehensive Variety and Specifications: Rooftop air conditioning units are categorized into three series by function: Cold Air Type (L), Heat Pump Type (R), and Constant Temperature and Humidity Type (H). The Constant Temperature and Humidity Type is suitable for process air conditioning environments with high requirements for temperature and humidity, while the Cold Air Type and Heat Pump Type are ideal for comfort air conditioning spaces.

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

Products are categorized into standard, purification, and fresh air series based on applicable usage locations, and various functional modules can be optionally added for convenient realization of cooling, heating, dehumidification, humidification, air purification, noise reduction, and energy-saving fresh air functions.

2. No dedicated machine room required, save on investment: The frame of this series of units is treated with anti-corrosion and waterproofing, 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 unit is a full-air system with no cooling water or chilled water system, which saves on chilled water pumps, cooling water pumps, cooling towers, fan coils, and piping accessories.

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

Small, lightweight, and customizable according to on-site conditions, easy to transport and install. 4. Cold bridge-free frame, low air leakage rate: The air handling sections use cold bridge-free aluminum alloy frames, with panels made of polyurethane high-pressure foam insulated sandwich panels (outer panel: electrostatically coated steel plate, inner panel: galvanized steel plate). The frame and panels are equipped with special sealing insulation strips and a unique outdoor rainproof structure design, ensuring outdoor operation of the unit.

With required corrosion and rust resistance, vibrant colors, and elegant appearance. 5. The unit employs a brand-name fully enclosed scroll compressor, offering stable operation, reliable performance, and high refrigeration efficiency: Customized units with heat recovery for energy conservation and environmental protection can also be provided upon customer request.

6. Equipped with a direct-drive low-noise axial flow fan and a rear-tilt centrifugal exhaust fan, with effective anti-vibration measures in place to ensure the unit operates smoothly and reliably with low noise and minimal vibration.

7. A variety of refrigeration accessories and control components are for international brands, featuring high system operation reliability and stable performance.

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

9. Standard units feature intelligent instrument control, and industrial-grade programmable logic controllers (PLCs) can be optionally selected to meet customer requirements. Standard purification units are equipped with PLC control running optimized programs. They also come with fault self-diagnosis and alarm functions. The controllers are equipped with standard RS485 communication interfaces, enabling convenient remote control from a distance or connection to an intelligent control system, ensuring optimal equipment efficiency and reducing operating costs.

10. The unit's return air can be in various forms, such as horizontal supply, side supply on either side of the unit, upward supply, and downward supply, making it particularly suitable for the renovation of air conditioning systems in old buildings (simply reroute the existing return air ducts to connect with the main unit on the roof): Additionally, replacing the main unit that has reached the end of its service life is also convenient, alleviating any concerns for the users.

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, and more. The explosion-proof marking for the units is ExibeibibmbllBT4Gb. There are also products with the explosion-proof marking ExibeibibmbllcT4Gb. Please communicate and confirm with our technical department before placing an order.
