What to do if my Domnick Hunter Dryer has a high pressure drop?

  David ArmstrongAug 3, 2025
  To address high pressure drop in your Domnick Hunter Dryer, resulting in low pressure, first check and replace the pre/after filtration if it's nearing the end of its operational life. Also, verify the inlet conditions against the values quoted at the time of sizing to ensure the dryer isn't being overflowed or operating at a reduced system pressure. Ensure all isolation valves are fully open and inspect the system for any leaks. Confirm drain cocks and pressure relief valves are closed. Lastly, check the dryer and compressor power indicators, isolators, and fuses in case of a power supply interruption.

How to fix poor dewpoint in my Domnick Hunter Dryer?
- A
  Amanda GrahamAug 13, 2025
  If you notice a poor dewpoint, indicated by water in the downstream piping of your Domnick Hunter Dryer, start by checking if the dryer is operating within its sizing criteria, comparing actual inlet parameters and environmental conditions to the original sizing values. Ensure the bypass valve is fully closed and allow sufficient time for the system to dry down after a recent start. Inspect the condensate drains for any faults and make sure the drain hoses are free from kinks or obstructions. Also, ensure the drain isolation valves are fully open. If the regeneration column pressure exceeds 350mbar, replace the exhaust silencers. For timer, valve malfunctions or if the desiccant is near its end of life, contact a Domnick Hunter approved service agent.

  If the air supply downstream of your Domnick Hunter Dryer is interrupted, causing a rapid loss of system pressure, first check the compressor to ensure it is running. If the compressor is functioning, check the dryer fault indicators for any fault shutdown events.
