The microcomputer control ensures the product's performance and quality are showcased and optimized.

The unit is divided into two parts: the compression condensation section and the air handling section. The compression condensation section is assembled in modular fashion, while the air handling section is designed with modularization by function. The housing features an aluminum alloy frame with frost bridge prevention and a polyurethane sandwich panel structure with double-sided steel plates. The unit's assembly methods are versatile and flexible, allowing for easy installation on rooftops or outdoor open areas without the need for a dedicated machine room. The product is suitable for large industrial sites such as factories and workshops in areas with不便 access to water or water scarcity, as well as for comfort-based air conditioning systems in places like hospitals, malls, supermarkets, restaurants, and office buildings.

Roof-type Explosion-Proof Air Conditioning Unit Product Features

1. Comprehensive Variety and Specifications: Rooftop air conditioning units are divided into three series based on function: Cold Air Type (L), Heat Pump Type (R), and恒温恒湿型(H). The恒温恒湿型is suitable for technical 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 areas.

Products are available for customization with cooling capacities ranging from 12kW to 490kW, catering to different high airflow and space-specific air conditioning needs.

Products are categorized into standard, purification, and fresh air series based on applicable usage locations, and various functional sections are available for selection, facilitating a range of functions such as cooling, heating, dehumidification, humidification, air purification, noise reduction, and energy-saving fresh air.

2. No dedicated machine room required, saving 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, without a cooling water or chilled water system, thus saving on auxiliary equipment such as chilled water pumps, cooling water pumps, cooling towers, fan coils, and piping.

Investing in preparation has reduced the construction cost. 3. Convenient transportation and easy installation: The unit design features two structural types: Standard and Purification models. Standard models with cooling capacity below 140kW are designed as an integrated structure, while those above 140kW are split into separate units for easier transportation and installation. Purification models are modularly designed, with configurable functional sections as needed, featuring simple and versatile configuration. The volume of each functional section

Small, lightweight, and customizable to site conditions, easy for transportation and installation. 4. Cold bridge-free frame, low air leakage rate: Each air handling function segment features a cold bridge-free aluminum alloy frame, with panels made of polyurethane high-pressure foam insulated boards (outer panel: electrostatic spray painted steel plate, inner panel: galvanized steel plate). The frame and panels are equipped with special sealing and thermal insulation strips and an exclusive outdoor rainproof structure design, ensuring outdoor operation reliability and efficiency.

With required corrosion and rust resistance, vibrant colors, and a stylish appearance. 5. The units are equipped with a renowned fully enclosed screw compressor, ensuring smooth operation, reliable performance, and high refrigeration efficiency: customized heat recovery units can also be provided upon customer request, promoting energy saving and environmental protection.

6. Equipped with a direct-drive low-noise axial fan and a rear-tilted centrifugal blower, along with effective vibration isolation measures, ensuring the unit operates smoothly and reliably with low noise and minimal vibration.

7. A variety 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 for high efficiency and energy savings.

9. Standard units are equipped with intelligent instrument control and can be optionally fitted with industrial-grade programmable logic controllers (PLCs) to meet customer requirements. Purification units are standardly configured with PLC control, operating under optimized programs. They also feature self-diagnosis and fault alarm functions. The controller is equipped with a standard RS485 communication interface, facilitating remote control from a different location or connection with an intelligent control system, ensuring optimal equipment performance and reducing operational costs.

10. The unit's return air can be in various forms, including horizontal air distribution, side air distribution on both sides of the unit, upward air distribution, and downward air distribution, making it particularly suitable for改造old building air conditioning systems (simply reroute the existing return air ducts to the roof to connect to the main unit). Additionally, replacing the main unit that has reached the end of its service life is also very convenient, alleviating any concerns for the users.

11. 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 ExibeibibmbllBT4Gb. There are also products with the explosion-proof marking ExibeibibmbllcT4Gb. Please contact our technical department for confirmation before placing an order.
