Fouling build-up in heat exchangers and condensers are an ongoing problem with high impact. Excessive consumption of electricity, high budget for maintenance and repair, shortened life spans of equipment and standard over-design of heat exchanging units are just a few examples of the issue related to fouling.
In the ere of environmental consciousness governments corporations are adapting more responsible attitudes towards the consequences of fouling.
Automatic on-line cleaning system are the answer to the problems as only these.
The brush cleaning system consists of two catch baskets and one brush for each heat exchanger tube. Both baskets are permanently fitted to the pipe ends and serve to accept the brushes.
By reversing the direction of the cooling water flow, the brush is pressed through the tube and at the otheer end it is accepted by the basket. When the cooling water stream is diverted again in the normal direction, also the brush will return into the catch basket located at the delivery end, the inner walls of the tubes thus being cleaned now.
The reversal of the water flow direction occurs by means of a reversing armature which can be set to any desired cycle via andelectric actuator and control box. This cleaning interval is fixed by our engineers according to the operating conditions and degree of contamination ot the cooling medium, but dependent on seasons or other influences it may also be changed by the operating personnel.
The cleaning action of the brush makes it possible to remove losse, gelatinous deposits from the internal surface of the tube without any restriction and hard deposits, tending to adhere more strongly, cannot even get the opportunity to form. More over, sludge accumulations or other contamination are precluded.
The benefits of the EQOBRUSH system have been most widely demonstrated by the huge number of worldwide applications. The EQOBRUSH system is accepted in HVAC and industrial applications.
