Grease Trapper ESP pollution-control unit addresses three chief complaints of restaurant operators: the need for better environmental control, reducing downtime and cost associated with maintenance, and manual cleaning. The unit uses two electrostatic precipitator (ESP) modules and carbon filters to remove grease, smoke, and odors from the exhaust airstream. For solid fuel applications, three ESP modules and two carbon modules handle the load. Air enters the ESP cell and passes an ionizer that positively charges particles in the airstream. Entering the collector portion, particles are attracted to negatively charged plates, removing contaminants. Automated cell wash down replaces manual cleaning.
