Air-Cooled Screw Chiller

Product Features

1. Applies low-rotational hot air fan with smooth, and the working noise level is obviously reduced. The unit control system adopts small vibration, easy to install. It is favorable for what there is lack of water supply, and water –cooled tower is not installed.
2. According to load requirements of unit, which have already achieved automatic programmer control with energy-saving.the human machine interface configures a full touch screen, which enables accurate and visual monitoring. Applies step and stepless capacity control with reaching the maximum energy efficient ratio.
3. Equipped with special air-cooled (semi-hermetic) screw compressor imported from abroad, the compressor operates reliably, efficiently, easy maintenance, exact volume control, and a wide range of application. The system adopts the latest asymmetric rotor profile. Build-in pressure drop lubricant to system with low vibration, low in noise, high performance.
4. Complete protection device: to prevent compressor starting frequently, over-current protection, overheat of motor protection, prevent freezing, sight glass in liquid, oil heating protection, phase protection. HV/LV protection, discharge high-temperature protection, safety value, soluble chock, water shut-off protection
