    The low negative pressure in the feeding place leads to low air leakage from the input, thus keeps the hot air in the dryer steadier with the temperature and the velocity. Counterflow : Wet material is introduced into the drum on the opposite end that the hot gas enters the dryer and dry material discharges on the opposite end of the dryer as the exhaust vapour

    Dec 04, 2012 If it runs OK on a non-GFI then it is leakage current. The GFI monitors the amperage coming into the unit (L1) and the amperage leaving the unit on the Neutral, if they vary by a few milli-amps then it trips. I think your unit has a moisture sensor (2 metal strips) in the drum area

    The dryer normally operates on a two fan, balanced draught system, whereby the gas inlet is maintained under slightly negative pressure to minimise air in-leakage. When drying (and/or preheating) materials which are unaffected by heat or exposure to a flame, an oil or gas burner can be arranged to fire directly into the drum

    Oct 15, 2010 easiest way to test the RCD is to unplug everything (yes everything) especially water pumps, fridges, freezers, water coolers etc and then test the Dryer - if it trips then you have an issue with the dryer. RCDs measure the current flowing through the active and the current coming back through the neutral, so if you have 10 amps flowing to the dryer then you should have 10 amps flowing through the neutral, they cancel each other - your RCD
