KRAD Features:

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.

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.

Easy To Access
The cooling compartments can be easily reached in seconds via the removable panels.

Easy Ducting
Condensers are located at the top for easy ducting.

Pressure Switches
Pressure switches are put in to the electrical box for easy access. There is no need to interrupt the cooling loop in case of pressure switch failure.

Compact Design
Every square inch inside the dryer is utilized.

Digital Interface Controller
Controller has 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
They filter the compressed air to .01 micron.
