Access doors are an important part of boiler maintenance and reliability.  If doors for inspection do not exist, or doors are hard to open, then the inspection of an area may be postponed or ignored.  This practice allows problems to go undetected until they become BIG problems.

Many styles of access doors require two people to open, or require frequent repairs to the door frame studs.  This manpower could be better used for other maintenance tasks.

HRST has developed a retrofit "easy open, easy close" door for HRSGs.  The only tool required for opening is a hammer.  (Most boiler people are good with a hammer!)  The door components can be opened quickly and lifted by one person.

We can offer door sizes customized for the specific location in your HRSG.

Compared to 15-20 minutes to enter through the old style door, plus all the maintenance. To sum it all up your door is terrific…"
