Problems Existing in Untreated Compressed Air:

Compressed air is an important power which is widely used in various area of industry. All air of compressed system is from atmosphere, among which has large amount of dust, vapor, not fully burned hydrocarbon and bacteria.
In addition, lubricant system of air compressor will also produce some pollutants. All of this mixed together will form a kind of corrosive oil sludge which damages device, corrodes pipeline, increases maintenance cost, pollutes environment, etc.

Installation of one set of Domnick Hunter Oil-Xplus filter and PoloStar Refrigerated dryer system can avoid huge economic loss caused by above problems.

Characteristics of PoloStar Refrigerated Dryer:

Precise Control
microprocessor control panel (PD1100 and above models are standard configuration), use conveniently, precision control and easy maintenance.

Simple Installation
PoloStar PD series Refrigerated dryer is the most compact one in similar products, its positioning and installing are very convenient. PD0050-PD0300 model of dryer even can install on the wall.

Easy to Use
PoloStar PD dryer can operate in extremely bad condition; it can work normally under max. air inlet temperature of 60℃ and max. ambient temperature of 50℃.

High Reliability
PoloStar PD series Refrigerated dryer can ensure continuously normal operation. Firmly aluminum heat exchanger advanced scroll compressor, PD2600 and above configuration of condenser and filter all have high reliability, which improve performance of dryer and reduce possibility of maintenance.

Drypack High Efficiency Heat Exchanger
PoloStar PD series Refrigerated dryer adopts advanced Drypack heat exchanger (PD0700 and above model are standard configuration).
