A very specialized approach is required when carrying out heater revamps in existing installations. This work often takes place in an operational factory setting and can resemble downtime maintenance activities. The work activities for heater revamps in existing installations demands a very specialised approach. Ovens are often adapted in an operating factory, making the conditions of the work activities look like the work activities of a maintenance downtime. The technical implementation, however, in such small surface areas requires a specific approach and thorough planning to the finest detail.  

MOB has a wealth of knowledge in heater revamps and has successfully carried out a number of complex heater revamps project in recent years:
