Pneumatic Cleaning System [Item No. KRT-W540-S]
The complete pipe-type heat exchanger is cleaned by periodic impulses of compressed air when in operation. The
process of cleaning takes place as blasts of the various sections that follow one after the other. The detaching of the ash
on the heat exchanger pipes is carried out by very short but strong pressure impulses. The detached particles are
carried by the flow of gas to the de-asher, where most of them are separated off. The system is built into the rear side of
the boiler. The compressor should preferably be installed at a cool spot in the heating room.
How the control system works:
The number of cleaning cycles within one time unit (e.g. per hour) is adapted to the loading of the boiler. One individual,
complete cleaning cycle consists of a series of pressure impulses over all the sections of the heat exchanger.

When this item is used, the compressor listed in the item "Pneumatic Cleaning System" is no longer required.
Reduced Price for Compressed Air Provided by Customer [Item No. KT-WL]
As a result, the compressor listed in the item "Pneumatic Cleaning System" is no longer required. The compressor
provided by the customer has to deliver at least the quantity and quality of air specified and have an adjustable pressure
controller as well as a safeguard against hose rupture (e.g. operating time limiter).
