Inspection, Maintenance & Servicing

Service Scheduling 

BRUSH Service is fully equipped to provide all existing operators with a comprehensive, standard or bespoke support package, that may be adapted to suit each and every individual operator’s need, wherever the installation be situated.


Regular Maintenance

The notion that "prevention is better than cure" lies at the heart of any maintenance programme. Regular maintenance may be categorised into the following terms:

  • Preventative maintenance utilising regular inspection packages bespoke to the customer's planned outage periods and the holding of strategic stock of parts.
  • Predictive maintenance utilising specific maintenance based on regular inspections and assessments of equipment condition and replacement material requirements.
  • Life-cycle maintenance utilising maintained stock of parts and exchange of strategic parts.
