Rypos’ Ultra Low Emissions Diesel Particulate Filter for Transport Refrigeration Units (ULETRU DPF) offers an immediate and measurable solution that combats climate change on roadways by reducing black carbon and other short-lived climate pollutants by up to 95%.
This cost-effective solution protects the environment and the health of local communities and helps older diesel engines achieve regulatory compliance and extend their useful life. Our Ultra Low Emission Diesel Particulate Filters (ULETRU DPFs) remove up to 95% of DPM from diesel TRU emissions immediately on installation with models compatible with either Thermo King® or Carrier® refrigeration units. Our DPFs allow TRUs to meet CARB Level 3+ and EPA emissions compliance requirements.
