Roof Mount 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 applications.

Products are available for customization with cooling capacities ranging from 12kW to 490kW, catering to requirements for various high air volume and different space 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 has 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 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 comes in two structural forms: standard and purification types. The standard type units with cooling capacity below 140kW are designed as an integrated structure, while those above 140kW are designed as split structures, which are convenient for transportation and installation. The purification type units are modularly designed, with configurable functional sections as needed, featuring simple configuration and flexibility. 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 treatment sections use cold bridge-free aluminum alloy frames, with panels made of polyurethane high-pressure foam insulated sandwich panels (outer panel: electrostatically sprayed steel plate, inner panel: galvanized steel plate). The frame and panels are equipped with special sealing and insulation strips, as well as a unique outdoor-type rainproof structure design, ensuring the unit's outdoor operation is secure.

With required corrosion and rust resistance, vibrant colors, and aesthetic appeal. 5.
