The integral rooftop air conditioning unit is one of the key 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, convenient installation beautiful appearance etc. The integral rooftop air conditioning unit can be wildly used in villas, stations, shopping clubs, workshops, industrial plant and other civilian or industrial establishments.

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. 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.

3. 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.

4. 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.

5. Unique design
For the evaporator and condenser, we use enhanced heat transfer technology,, so the unit is high efficiency and energy saving; Besides, the unit can achieve centralized control with can timely control the matching condition of the energy of the unit and the load of the air conditioning room, so that the unit can operate in the best situation. The energy saving effect is remarkable and the operation cost is low.

6. 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.
