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 segmented by function. The housing is constructed with a cold-bridge-free aluminum alloy frame and a polyurethane sandwich panel structure with double-sided steel plates. The combination of the unit is flexible and diverse, allowing for easy installation 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 limited water resources, as well as for comfort-oriented locations like hospitals, malls, supermarkets, restaurants, and office buildings, where a full-air air conditioning system is required.

Roof-mounted 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 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 the needs of various high-airflow and different-sized air conditioning locations.

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 including 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, thereby saving on auxiliary equipment such as chilled water pumps, cooling water pumps, cooling towers, fan coils, and piping.

Investment-ready, reducing the construction cost. 3. Easy transportation and installation: The unit design includes two structural types: Standard and Purification models. The Standard model has a total structure for cooling capacities under 140kW and a split structure for capacities above 140kW, facilitating transportation and installation. The Purification model is modularly designed, with configurable functional sections as needed, offering simple configuration and versatility. 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 handling sections use cold bridge-free aluminum alloy frames, 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 and insulation strips, and feature a unique outdoor rainproof structure design, ensuring the unit operates reliably outdoors.

With required corrosion and rust resistance, vibrant colors, and a stylish appearance. 5.
