DERC Air Preheater Cleaner

PLC Controlled Water Jetting of Air Preheaters

Air Preheaters pollute during operation, making the efficiency of the air preheater going down which affects the entire process in a negative way. With this high pressure system it is possible to clean your air preheater full automatic cleaning quick and efficient. The DERC Air Preheater Cleaner is a full electric model, PLC controlled and set with a touchscreen. The Air Preheater Cleaner is designed to clean with high pressure waterjetting in a safe, effective, efficient and ergonomic way. The operator monitors the Air Preheater Cleaner from a safe distance. Your installation will be back in top condition.

Air Preheater Rails

The Air Preheater Cleaner moves along an aluminum rail. The rail has slotted holes in which the carriage moves. The rail is mounted on the in- and outside of the air preheater with two supplied clamps. The electric motor with encoder and the PLC provide an extremely accurate positioning of the carriage of the cleaning manifold.

Manifold & Flows

The Air Preheater Cleaner will be delivered with a high pressure manifold. You can choose a 4- or 5-jet manifold with a maximum working pressure of 700 bar/ 10K. The maximum capacity of the air preheater cleaner depends on the span of the rails. For example a rails of 6 meters with 2 suspension points is 250 l/min by 700 bar working pressure. When the rails are supported on more places, the maximum flow can be larger. For extreme high flows or pressures, we recommend the XXL-version.

PLC Set on Touchscreen

The Air Preheater Cleaner is positioned very accurate (+/- 1 mm). The operator chooses which program to use. There is an automatic program; the Air Preheater Cleaner calculates the steps on the given parameters or the operator defines the steps and cleaning time.

During the proces, the operator can either interrupt, change or restart the program or control the system manually. The logged data has an unique identity and can be downloaded via the USB port. The operator monitors the cleaning at a safe distance, outside “the line of fire”. The PLC automatically controls the process.
