KSTAR fluorine pump free-cooling air conditioner is an efficient and energy saving air conditioner developed by KSTAR, it can fully use of natural cold source to reduce the energy consumption of the unit. Based on the KSTAR standard air cooling unit, it can achieve the cooling function using the compressor system or the fluorine pump system through the refrigerant cycle, no need to add pipe net system and draw into the fresh air. With the integrated design concept, it has the advantages of installation and maintenance easily, high reliability, high efficiency, energy saving and so on. It can be applied in various types of data centers, communications room and other places.

General Features

● High efficiency and energy saving

When the outdoor environment temperature is low, shut down the compressor to fully use of natural cold source and reduce energy consumption;

Fluorine pump free-cooling precision air conditioner use high efficiency and energy saving parts, so it has the advantage of environmental protection and energy saving as the KSTAR other precision air conditioner product.

● High reliability

Use high quality parts which have great performance over time;

Advanced and reliable controller ensures that the unit switches the cooling mode automatically, various protection functions ensure the unit running safely and reliably.

● Easy to use

Highly integrated and modular design, easy to install and maintain;

Intelligent communication ports
