NexGen Isolator Catch Basin Inserts provide positive control containment of deicing fluids just below the surface of the airside-rated grate, mitigating chances for glycol to seep into construction joints. Keeping spent deicing at the surface simplifies collection procedures with mobile collection units, allowing operators to drive over the grates to vacumm them out. A small stinger wand can be inserted in the grate to complete the final clean up. Switching back from surface containment to storm water discharge is quick and easy. From the surface, turn a driver key six times to quickly open the value. Use the Isolator Catch Basin Inserts to get simple, effective control of your spent deicing fluids and ramp into your ELG compliance level.
