EPG's Top Ten List of things to help prevent corrosion in control panels and electrical enclosures exposed to moisture, landfill gas, and other application & environmental factors.
Updated Event Schedule (Postponements and Cancellations)
Change
corrosion inhibitors every year. Each control panel and breakout junction box EPG manufactures has one installed.
Replace
desiccant dryers when color changes from blue to pink. If the desiccant material has turned white, it is no longer protecting the level sensors internals from moisture.
Seal-offs should be installed in each conduit run between riser/sump and control panel. *Seal-offs are ineffective unless the damming fiber and sealing compound are in place so be certain this is done.
Since
electrical conduit threads are straight and do not seal, they should be sealed with
Teflon™ tape. *This does eliminate conduit as a ground so a
separate ground wire must be installed.
Make sure enclosures are
plum and level to insure doors are straight and seal properly. Inspect doors and make sure they are not bent and keep them closed by
securing ALL latches.
During
inspection of control panels and breakout boxes, make note of any signs of water stains, discoloration of fuses, wiring, or terminal corrosion. These are signs that the enclosure has been compromised by moisture and/or gas.
Any evidence of
insect or small animals inside the enclosure should also be addressed.
EPG recommends that control panels be mounted in a secure fashion at least 1
5' from the riser or sump and 36" above grade to the bottom of control panel. If in the design stage, please strongly consider these recommendations.
Reinstall and/or replace
cord restraints and replace
o-rings of Meyer's hubs after any cable repair or maintenance is performed.
Use
water-proof wire connectors where ever wire connectors are needed.

Product Highlight
Three simple yet often overlooked items vital to maintaining performance and longevity of your pumping systems include desiccant dryers, corrosion inhibitors. and conduit seal-offs.
Dryers and inhibitors are expendable and replacing them on a regular basis is easy and economical. Installing seal-offs properly at installation is your first line of defense against migrating gas and moisture and are inexpensive compared to the replacement cost of instrumentation, components, and wiring repairs due to corrosion.
Industry Events
We will do our best to keep this list updated over the next several months. Please note some events have been rescheduled or postponed recently. New rescheduled dates are listed.
