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

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恒温恒湿型(H). The恒温恒湿型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 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 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, 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 construction space and civil engineering investment costs: The units are all-air systems, without cooling water or chilled water systems, thereby saving on auxiliary equipment such as chilled water pumps, cooling water pumps, cooling towers, fan coils, and pipelines.

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

Compact, lightweight, customizable to 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 insulation strips and a unique outdoor-type waterproof structure design, ensuring outdoor operation of the unit.

With required anti-corrosion, rust-proof, and corrosion-resistant properties, vibrant colors, and stylish appearance. 5. The unit employs a renowned fully enclosed screw 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.
