Explosion Relief Door Service & Maintenance

PSD provides onsite service and maintenance support for explosion relief doors throughout the United States.

While PSD doors are designed to require minimal maintenance, certain components may eventually require inspection, replacement, or recalibration depending on the application and operating environment.

Common Maintenance & Service Needs

Over time, certain components may wear due to:

• Temperature cycling

• Corrosive environments

• Frequent door access

• Harsh operating conditions

The most commonly replaced components include:

• Gaskets

• Springs

• Magnets

• Hardware and fasteners

Service After an Explosion Event

PSD explosion relief doors are designed to rapidly open during an event and withstand activation.

After activation:

• Doors must be manually reclosed

• A visual inspection should be performed

• Gaskets and sealing surfaces should be checked

• Door operation should be verified

The severity of the event determines whether additional service or recalibration is necessary.

Fast Response When Needed

Standard response times depend on scheduling and technician availability, but PSD has responded to urgent service requests as quickly as the next day when possible.

Why PSD Service Is Different

PSD technicians are uniquely qualified to recalibrate and service PSD explosion relief doors properly.

Many PSD doors arrive pre-calibrated and ready for installation, but onsite servicing requires specialized knowledge of the system’s mechanical calibration and operational requirements.
