Keltec KRAD-750 – 750 CFM Non-Cycling Refrigerated Air Dryer, Internal Filtration down to .01 Micron, 460V/3Ph Keltec

WHY TREAT COMPRESSED AIR?

The importance of compressed air as a provider of energy for modern industrial processes is widely known. What is often overlooked however is the need to provide quality treatment for this air. In fact, the air entering the system contains moisture, in vapor form, along with environmental contaminants, which are concentrated during compression. When cooled, this moisture will turn into liquid water, causing extensive damage not only to the compressed air network, but also to the finished product. Left alone, these materials would reduce the service life of downstream equipment and contribute to system corrosion. Keltec refrigerated dryers actively remove this condensate and particulate contamination, and achieves extremely dry and clean, compressed air.

The benefits are notable; less system down time, reduced maintenance costs and an improved, finish product.

HIGHLY ENGINEERED

With a pressure drop of less than 3 psi, energy costs are greatly reduced.

 

DESIGNED FOR TROPICAL CONDITIONS

Keltec-Technolab air dryers can effectively operate with 140 F inlet temperatures, due to their use of R134A refrigerant across the dryer range, and through the use of an over sized condenser. With a pressure drop of less than 3 psi, energy costs
are greatly reduced.

COMPACT DESIGN

Every square inch inside the dryer is utilized.

DIGITAL INTERFACE CONTROLLER

8 temperature sensors, enabling complete system monitoring.

ALUMINUM PLATE HEAT EXCHANGER

Very Low Pressure Drop (2psi) Very Efficient (38 F real pressure
dew point)

SCROLL COMPRESSORS

The scroll compressors used are energy efficient and resistant to liquid shock.

INTEGRATED DUAL FILTER SYSTEM

Dual internal filters that filter the compressed air to .01 micron

ELECTRICAL WIRES ARE SEPARATED FROM REFRIGERANT SIDE

There are no electrical wires inside the refrigerant side of the dryer. The electrical box has an external cover which has an access from the outside of the dryers. There is no need to open the dryer panels to enter the electrical box.

ALL WIRES INSERTED INTO PLASTIC CABLE HOLDERS

Wires connected to the electrical box with conduits

EXTRA BALL VALVES

Extra ball valves are brazed in to the refrigerant circuit in order to simplify parts
replacement, without the chance of releasing refrigerant gas from the system.

PRESSURE SWITCHES

Pressure switches are put in to the electrical boxfor easy access.
