1. Overview of New Full-Airflow Rooftop Explosion-Proof Air Conditioning Units

The units are widely used in industrial large-scale factories, effectively solving the issues of excessive indoor space occupation and noise from large units. The units come in various types such as constant temperature and humidity, clean type, and heating and cooling, with a cooling capacity range of 7.8KW to 208KW.

This product is suitable for water-scarce areas.

2. Installed on the roof, easy to install, does not occupy indoor space.

3. Features sufficient outdoor overpressure, facilitating air duct ventilation and significantly reducing indoor noise.

4. Comprehensive variety and specifications to meet diverse requirements.

5. The large cooling capacity unit frame is made of interrupted cold bridge aluminum alloy profiles, which cause cooling capacity leakage and condensate water due to the significant temperature difference inside and outside the unit.

6. All major components are imported, featuring superior performance.

7. Evaporators and condensers utilize enhanced heat transfer technology for energy-saving.

Section 2: Detailed Description of New Type Explosion-Proof Rooftop Air Conditioning Units

Roof-top air conditioning units are particularly suitable for a variety of applications including supermarkets, banks, hotels, office areas, industrial settings, and airport terminals. The units can be installed either on the roof or on the ground. In addition to providing thermal and humidification treatment for the room air, they also offer additional features like filtration and noise reduction. Moreover, they can easily bring in fresh air from the outside. The unit features the following characteristics:

Silent Operation: Optimized air flow channels minimize noise and vibration, with additional noise from the channels further reduced. The use of superior sound-absorbing materials inside the channels also reduces the overall noise of the unit. To isolate the main noise source – the fan – vibration dampeners are installed underneath, ensuring the unit operates in ultra-quiet conditions.

Transparent Control: A large, high-definition LCD screen clearly displays all operational parameters and fault inquiries for the equipment.

Energy Regulation: Larger units are equipped with multi-compressors for operation, enabling automatic energy adjustment to 0/50/100 based on energy demand.

Variable speed operation: The unit can be equipped with a variable speed axial flow fan as needed. The microcomputer automatically controls the fan speed based on the outdoor temperature, ensuring that the condensing pressure is not too high during the day when temperatures are higher, and the unit operates with very low noise at night when temperatures are lower.

Durable: The unit housing is made of galvanized steel with powder coating and has passed at least 2000 hours of salt spray testing in compliance with ASTMB117-95 standards, ensuring resistance to all harsh environmental conditions. The external fasteners are made of stainless steel.
