Air Compressor Oil Coolers Only as Strong as its Weakest Joint
Extreme duty cooler construction eliminates major cause of failure
Compressor dealers have been reporting premature failures of original equipment oil coolers. Almost all original equipment oil coolers are manufactured from “bar and plate” construction. Bar and plate construction has inherent flaws in the manufacturing process. Active solves this problem by manufacturing our extreme duty coolers with extruded tubes.Posted:2012-02-16 11:44:23 by Kevin Montgomery
WARRANTY BULLETIN -- ELECTROLYSIS WARNING
A cooling system can hold large amounts of excess electrical current, which turns the coolant into an electrolyte. If this excess current cannot be discharged by means of a ground, it continuously travels through the system, causing electrochemical reactions with all surfaces it contacts. When it locates a favorable material, it goes to work devouring the material completely. Damage to internal engine components by means of cavitation is one result of electrolysis. Tube to header failures, solder bloom and individual tube or complete core failure will result from an ungrounded radiator. Voltage of zero to .3 is normal. A copper brass radiator can be destroyed in as little as seven days by .5 volts and as little as .15 volts will destroy an aluminum radiator. Electrolysis can be caused by several things: Bad grounds (loose, corroded, broken wire) Alternator over charging Static electric energy looking for a ground Accessories not installed properly (stereo, power amps, horn, lights, air bags, gauges, DVD player, two-way radio, back-up alarm, etc.) Testing for electrolysis A multi or voltmeter capable of reading both AC and DC currents is required to test cooling systems. Attach the black lead to the negative ground of the battery. Dip the positive lead into the coolant touching the coolant only. Read the voltage with all equipment turned off. Read the voltage with the electrical starter engaged. Read the voltage with the engine running and all systems turned on: lights, coolers, fans, heaters, air conditioning, cell phone, two-way radio, including the phone and radio on both standby and transmit. Proper grounding of the radiator to the vehicle frame using a 10 to 12 gauge wire is the key to removing electrolysis from the cooling system. Damage caused by electrolysis is easily identified and radiators damaged by electrolysis WILL NOT be covered by warranty.Posted:2012-01-26 12:22:32 by daveg
