Looking for an enhanced tester to verify correct voltage supply to Graham-White’s 994 and 975 Air Dryers as well as cycling the dryers?
Frustrated at having to listen for the pneumatic exhaust of the dryer over the noise of the rail yard?
Do you have a need to eliminate subjectivity when demonstrating to inspectors that dryers are cycling properly?
Do you want the ability to positively demonstrate the proper power connections are in place and working?
How about the ability to verify memory operation without having to vent main reservoir pressure in order to manually cycle the compressor on and off?
At the request of our customer base, Graham-White proudly introduces the 5666-150 redesigned, hand-held, portable, electronic Air Dryer Power Analyzer.
The analyzer will detect and identify the correct constant supply voltage (74 VDC nominal), intermittent (74 VDC Signal) voltage and incorrect reverse polarity for both constant and signal voltages. Additionally, correct cycling and time cycle of the 975 dryer (60 seconds each side) and the 994 dryer (1 minute 5 seconds each side) can be verified using the Power Analyzer test switch without the compressor cycling.
