GRAD air cooled scroll chiller comes with an intelligent defrosting system which features timely and completely defrosting performance. So the heat dissipation can be avoided to a great degree. Other automatic control functions cover energy management, anti-freezing inspection, and so on.

Feature of air cooled scroll chiller
1. The chiller comes with high-efficiency and low-noise scroll compressor and low-speed cooling fan, making the operation really silent.

2. Due to the small size of the chiller, this air conditioner can be installed at various places like the floor, roof, balcony, and so on.

3. It can be used for both cooling and heating.

4. The heat exchangers at both the air side and the water side are made of highly efficient thermal conductive pipe.

Application
Air cooled scroll chiller has found wide application in the central ACs of these following places: hotels, shopping malls, office buildings, exhibition halls, airports and many other public facilities. It also meets different requirements of industrial air conditioning systems in many fields, including electronics, pharmaceutical, biological, textile, chemical engineering, metallurgy, electric power and machinery.

Standard operating mode
Cooling: Ambient temperature: 35℃; Inlet water: 12℃, outlet water: 7℃
Heating: Ambient temperature: 7℃DB/6℃WB; Inlet water: 40℃, outlet water: 45℃

Constant Temperature and Humidity Machine
1. Upflow air supply type: It can be configured with a hood.
2. Downflow air supply type: It can work with a raised access flooring system to achieve a better effect.
3. Specially designed for high-sensible-heat places, ensuring constant temperature and humidity indoors. More energy saving
when compared to common air conditioning systems. Suitable for use in high-precision machine rooms and computer rooms
4. High-precision, multifunctional microcomputer controller with setting, display, alarm and central monitoring functions keeps indoor temperature within ±1℃ and relative humidity within ±3%.
5. Medium-efficiency filter keeps indoor air clean.
6. Multiple protection and control systems available

Cooling Conditions
1. Air cooled:
Outdoor dry bulb temperature: 35℃
Indoor air inlet temperature: 23℃
Wet bulb temperature: 17℃
2. Water cooled:
Cooling water in/out temperature: 30℃/35℃
Indoor air inlet temperature: 23℃
Wet bulb temperature: 17℃

VRV System
VRV, short for variable refrigerant volume, is an evaporative cooling system. It meets the load requirements of indoor cooling and heating in a way of controlling the circulating refrigerant in the compressor, as well as the refrigerant flowing into the indoor heat changer.

Main Advantages
1. Economical and energy saving: A high-performance Copeland compressor enables it to achieve an output of wide range and high precision. Besides, it also features high efficiency, energy saving, security and reliability.
2. Easy installing and maintenance: Equipped with an air cooling device, it’s usually installed in balcony, roof or on the ground. There is no need of a machine room or a special base.
3. Our intelligent direct-current central air conditioner RXV-4 adopts the latest driving technology of direct current conversion with a 180-degree sine wave, as well as the R410A environmentally-friendly refrigerant. It meets the requirement of RoHS instruction and offers a precise temperature control, guaranteeing our clients have an amazing and extraordinary experience.
4. It can heat up and cool down quickly. The temperature is kept within ±0.5℃.
5. The maximum length of the refrigerant piping is up to 175 meters. The altitude difference between indoor and outdoor units in the same system is 50 m while between the indoor units is 30m, which is unrivalled in this industry. The first branch pipe is 40m away from the farthest indoor unit.
6. Latest balancing technology between oil and air
7. Thanks to our newly designed turbo blower, our machine operates with little noise.

Applications
It finds wide application in both commercial buildings and resident area, including high-end apartments, duplex buildings and office buildings.
