What to do if the air supply downstream is interrupted in Parker PNEUDRI Maxi MX Dryer?
If the air supply downstream of your Parker Dryer is interrupted, leading to a rapid loss of system pressure, the compressor might be switched off; check the compressor. Also, check the dryer fault indicators for any fault shutdown events.
Why does my Parker PNEUDRI Maxi MX Dryer have a high pressure drop?
A high pressure drop in your Parker Dryer, leading to low pressure gauge readings or intermittent operation, can be caused by several factors. The pre/after filtration might be nearing the end of its operational life, so check and replace it if necessary. The dryer could be overloaded or operating at a reduced system pressure; verify the actual inlet conditions against the values quoted at the time of sizing. Also, check the position of all isolation valves to ensure none are partially closed. A pressure loss from the system could be the reason, so check the system for leaks. Make sure that the drain cocks and pressure relief valves are closed. If the dryer or compressor tripped due to a power interruption, check that the “POWER ON” indicator is illuminated; if not, inspect the isolator an...
What to do if my Parker PNEUDRI Maxi MX Dryer has poor dewpoint?
If your Parker Dryer has a poor dewpoint, indicated by water in the downstream piping, several issues could be the cause. First, ensure the dryer is operating within its sizing criteria by checking the actual inlet parameters and environmental conditions against the values quoted at the time of sizing. Confirm that the bypass valve is fully closed and allow sufficient time for the system to 'dry down' if the dryer has recently been started. Check the condensate drains for any faults and ensure the drain hoses are free from kinks and obstructions, and that the drain isolation valves are fully open. If the regeneration column pressure exceeds 350 mbar, replace the exhaust silencers. For timer or valve malfunctions, or if the desiccant is nearing the end of its useful life, contact a Parker d...
