The modular rooftop air conditioning unit is one of the most competitive products of Shenling. After many-years' continuous improvement, this series of unit are getting increasingly perfect with the features of high energy-efficiency ratio, low noise, high static pressure, high control accuracy, safety, reliability, little vibration, high degree of corrosion resistance, good sealing performance, excellent rainproof and dust proof performance, beautiful appearance etc. Besides, due to the modular design, the unit not only can meet different requirements, but also is easy to install.

1. Diverse specifications
Various types: refrigerating-only type, electric heating type, constant temperature and humidity type, heat pump type, fresh air type and clean type, etc
2. Free combination of multiple air handling section 
Sections: cooling, heating, humidifying, dehumidification, air purification, noise reduction, heat recovery, graded control of air flow rate and cooling capacity.
3. Multiple ways of placement
The air handling sections not only can be placed indoors, but also be fixed outdoors. The air handling sections can be in the same layer with the condensation and compression sections, but also can be not in the same layer. The unit has anti-sun exposure, anti-corrosion, anti-rain and other properties.
4. Superior Components
The main parts we use are all famous product with superior quality and high performance. The high efficiency scroll or screw compressors can work stably; The centrifugal fans have strictly passed the dynamic & static balancing adjustment test and are equipped with effective vibration isolation measures which can effectively reduced the noise.
5. Intelligent control　
The microprocessor control and liquid crystal display can not only control the temperature and humidity, but also have the functions of malfunction self-diagnose and malfunction alarm. Moreover, due to the simplified operating environment and user-friendly operation guild，you can set up the operating time any way so as to realize automatically monitor.
6.Multi- protection    　
Units are equipped with multi-protections，such as high/low pressure protection, short circuit protection, motor overheating protection, etc. All of those can ensure the unit operating safe and reliably.
7. Special treatment 
As the specific requirements of the operating occasions, the units can be design as anti-exploded and anti-corrosion. It can be widely used in the occasions which exist or possible exist Ⅱ A、Ⅱ B grade, T1 ~ T4 flammable gas or explosive mixture of steam and air in the industries of petroleum, chemical, metallurgical, military, medicine, etc.
