Inspection last week inside of the ductwork between the
hood and the Electronic Precipitator. (Taken from the hood)
While Electronic Precipitators work very well when maintained, there are still major issues that need to be addressed. As you can see in the picture above, the ductwork up to the precipitator still needs to be serviced as often as any duct without the unit. The KEC company doing this work obviously did not think cleaning anything past the hood was needed. Even past the Electronic precipitator needs inspections regularly also cleanings are needed less frequently when they are properly maintained. Remember that they will fail and all of the system will need to be cleaned if you fail to keep a proper service contract in place and keep the filters clean and in working order.
