The unit is divided into two sections: the compression and condensation section, and the air treatment section. The compression and condensation section is assembled in a modular manner, while the air treatment section is designed with modularization based on function. The casing is constructed with a cold-bridge-free aluminum alloy frame and a polyurethane sandwich panel with double-sided steel plates. The combination method of the unit is flexible and diverse, allowing for easy installation, 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 in areas with不便 access to water or water scarcity, as well as for full-air conditioning systems in comfort spaces like hospitals, malls, supermarkets, restaurants, and office buildings.

Roof-Type Explosion-Proof Air Conditioning Unit Product Features

1. Comprehensive Variety & 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Type (H). The恒温恒湿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 customizable with cooling capacities ranging from 12kW to 490kW to meet the requirements of different high air volume and space air conditioning applications.

Products are categorized into standard, purification, and fresh air series based on applicable usage locations, and various functional sections can be optionally added for easy realization of multiple functions such as cooling, heating, dehumidification, humidification, air purification, noise reduction, and energy-efficient 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.

Investment preparation 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 is an integrated structure for cooling capacities under 140kW and a split structure for capacities above 140kW, facilitating transportation and installation. The purification model is modularly designed, allowing for the configuration of various functional sections as needed, featuring simple and versatile setup. The volume of each functional section

Compact, lightweight, and customizable according to on-site conditions; easy to transport and install. 4. Cold bridge-free frame, low air leakage rate: The air treatment sections use a cold bridge-free aluminum alloy frame, with panels made of polyurethane high-pressure foam insulated sandwich boards (outer panel: electrostatically coated steel plate, inner panel: galvanized steel plate). The frame and panels are equipped with special sealing insulating 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 renowned fully enclosed scroll compressor, ensuring smooth operation, reliable performance, and high refrigeration efficiency: Upon customer request, non-standard heat recovery units can also be provided for energy-saving and environmental protection.

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

7. Various refrigeration components and control devices are from internationally renowned brands, featuring high system reliability and stable performance.

8. Both evaporators and condensers are copper tube-aluminum fin heat exchangers, designed and optimized by computer, and manufactured on a dedicated heat exchanger production line, ensuring high efficiency and energy savings.

9. Standard units feature intelligent instrument control and can be optionally equipped with industrial-grade programmable logic controllers (PLCs) as per customer requirements. Purification units are standardly configured with PLC control, operating under optimized programs. They also have self-diagnosis and fault alarm functions. The controller is equipped with a standard RS485 communication interface, enabling remote control from a distance or connection to an intelligent control system for optimal equipment performance and reduced operation costs.

10. The air handling unit's return air can be in various types such as horizontal supply, side supply to the left and right of the unit, upward supply, and downward supply, which is particularly suitable for the retrofitting of air conditioning systems in old buildings (simply redirect the original return air ducts to the roof for connection to the main unit): Additionally, replacing the main unit that has reached its service life is also very convenient, eliminating any concerns for the users.

11. Units can be treated for explosion-proof and corrosion resistance according to specific application requirements. They are widely used in industries such as oil, chemical, metallurgy, and pharmaceuticals. The explosion-proof marking for the units is ExibeibibmbllBT4Gb. There are also products with the explosion-proof marking ExibeibibmbllcT4Gb. Please contact our technical department to confirm before placing an order.
