Recycling Emission Control Equipment

Recycling Emission Control Equipment from Standby Diesel Generators

Red Fox Resources purchases passive diesel particulate filters (DPFs) from diesel powered backup or emergency standby generators.

Passive DPFs require the exhaust temperatures from the engine to burn off or oxidize the collected particulates in the filter for regeneration and to prevent the filter from plugging up.  Often diesel-powered backup generators only run periodically for testing purposes and rarely run under enough engine load for the exhaust to reach the required temperature for regeneration. This lack adequate operating temperature which causes the filter to plug up with soot and cause the engine to experience high backpressure.

This situation of plugged passive DPFs has led to many passive stationary DPFs having to be replaced with active systems that use an external energy source to burn off the collected soot.  The passive systems being replaced are generally catalyzed with platinum group metals (PGM) and carry a recycle value.  Red Fox buys back these spent passive diesel particulate filters for recycling.
