Compressed Air Dryer Service & Repair

A healthy compressor can still deliver wet air when the treatment train is not maintained.

Service approach

Treat the dryer as production equipment

A healthy compressor can still deliver wet air when the treatment train is not maintained. The assessment looks beyond the reported symptom and checks the conditions that affect dew point, drains and pressure-drop control in refrigeration and supported desiccant dryers.

Scope

What this service can cover

The quotation identifies inclusions, exclusions, parts, travel and items dependent on inspection.

01

Dryer and filters

Condenser, fan, refrigeration performance, drains, filters, dew point and pressure drop reviewed. For refrigeration and supported desiccant dryers, the final scope is matched to dew point, drains and pressure-drop control.

02

Air-quality support

Dryers, filtration, drains, condensate routing and point-of-use risk reviewed. For refrigeration and supported desiccant dryers, the final scope is matched to dew point, drains and pressure-drop control.

03

Cooling and ventilation

Coolers, fans, thermostatic control, room airflow and hot-air recirculation checked. For refrigeration and supported desiccant dryers, the final scope is matched to dew point, drains and pressure-drop control.

04

Pressure and control

Inlet valves, minimum-pressure valves, sensors, loading behaviour and distribution losses assessed. For refrigeration and supported desiccant dryers, the final scope is matched to dew point, drains and pressure-drop control.

05

Complete system checks

Compressor, receiver, dryer, filters, drains, pipework and point-of-use pressure reviewed together. For refrigeration and supported desiccant dryers, the final scope is matched to dew point, drains and pressure-drop control.

06

Service reporting

Machine details, readings, parts, defects, actions and next service trigger recorded. For refrigeration and supported desiccant dryers, the final scope is matched to dew point, drains and pressure-drop control.

When to act

Conditions that justify an inspection or service call

  • The current condition threatens dew point, drains and pressure-drop control
  • Service or inspection history is incomplete for the refrigeration and supported desiccant dryers
  • The same alarm, leak or pressure problem is returning
  • Parts are only ordered after a failure
  • The site needs a planned shutdown and clear work scope
  • Management needs evidence to choose repair, overhaul or replacement
