PURItech - Thermal Regeneration Unit for Particle Filter

The thermal regeneration unit is for burning off (regeneration) the soot of a full-loaded diesel particulate filter. Self-cleaning diesel particulate filters with catalytic coating (DPF-System) have to be regenerated, if applicable, in the thermal regeneration unit before cleaning the filter with compressed air. Filters without self-cleaning regeneration (exchange filter), the filter element has to be externally regenerated. If the filter module or exchange filter is loaded with soot, it has to be removed and regenerated in an external  thermal regeneration unit. The unit increases the temperature according to a pre-programmed procedure up to 650C that converts all soot particles into harmless substances.
