I am interested in recieving everyones perspectives on this subject please .
I picked up a recovery tank from a wholesaler . It was not bought new , just a recycled tank from Fielding Chemicals . If it is returned empty you get charged , if it is full no charge . In Ontario thats the general deal .
In the past I have posed the question to the wholesaler , what is the quality assurance that the tank is resonably clean ? The responce I was given was that there may be some undesirable vapores or an oil film in the tank from an unknown refrigerant or oil . I was never told that these tanks were the sole purpose for containment and transportation back to Fielding Chemical for clean up only . I have also never seen any documentation to support this .
I , and many mechanics and HVAC companies have been using these cylinders for serviceing systems , ie. recovery into and charging back into the same system . Only to be returned when the cylinder was full . Seemed kind of convienient .
Anyway , picked up a cylinder , evacuated the tank to 300 microns , recoverd into the tank and charged from the said tank back into the system . Well , when there was approx 10 pounds left I noticed the delta p on the suction gauge began to drop off . I removed the charging hose from the tank and found a fine dust , or dirt of some kind coat the bottom of my gauges manifold . The tank was poluted with some kind of debrise , dry debrise . No I did not use a dryer in line with my charging hose . Never have . Now I suspect there is debrise sitting in the bottom of the oil crank , or is hopefully getting trapped into the dryer . I left that circuit off untill the service manager can be informed . Does anyone use these cylinders for servicing ? Should the wholesaler not make provisions to state clearly that these cylinders cannot be used for servicing as described >|????? Anyone !!
