Aftermarket + Service


IMI ​Critical Engineering has always prided itself on best in class customer support of our products. Our reputation was built on solving customer's problems, resulting in IMI Critical businesses developing the products we have today to provide the robust, reliable and efficient service expected in the harshest of environments.

Our products are designed for the most extreme of environments – extremes of temperature, pressure, erosive media and severity of operation. Our engineers in IMI CCI, IMI Remosa or IMI Z&J in particular act as consultants partnering with customers through the design stage. It is crucial that we therefore support commissioning with our field service technicians – whenever and where ever your project is in the world.

We have our own in house field service technician team, backed up with planners, co-coordinators and health & safety to ensure true 24 hour service capability, 7 days a week across the world.

With 15 manufacturing plants supported by service centres across the world, we can provide OEM parts to meet your outage or turnaround requirements. With portable workshops, we can set up on site to ensure outage or refinery turnarounds are safely managed to time and cost.

Our field service technicians can also support service and repair on any installed valves and they are regularly asked to replace, upgrade or repair competitor's valves due to performance or reliability issues. We have a team able to engineer upgrades or replacements to meet your existing installation and configuration. This is critical for major refinery projects, where existing infrastructure to support the valves must be used.
Sector overview​:​



IMI CCI have over 250 field service technicians across the world. These are also supported by our world renowned Valve Doctors® for any plant operation issues you have. 

Since our acquisition of IMI Bopp & Reuther and IMI Zikesch we have built even further on our capability. We can provide aftermarket services for every valve, across all phases of a valve's lifecycle, anywhere in the world. We have also added over 100 additional service technicians to the IMI CCI team along with four additional manufacturing facilities and an efficient back office, providing fast and effective support.  We are able to assist your from the building and commissioning of the plant through regular maintenance and any retrofits, as may be required. This is why we have trademarked our slogan "We Solve Flow Control Problems​", it's a simple statement but it captures perfectly our commitment to solving your plant issues.

Since 1955, IMI Remosa has been operating in the field of industrial maintenance and specifically within refineries and petrochemical plants. With its proven experience in these areas, we are an excellent source of problem solving as a consultant for engineering, retrofitting and repair work for any type of valve installed in FCC Units and Expander Power Recovery Units. This capability allows the replacement of the internals, along with the modification of the valve inside geometry, without removing the valve from the line.

IMI Z&J has a field service team which will oversee the installation and commission of what are the largest valves in the world. We are experts in refinery turnarounds with technicians based out of our manufacturing locations in Duren, Germany and Houston, USA. Our expertise will ensure your plant is optimised whether it is delayed coking in petrochemical, blast furnaces in iron & steel mills or the glass industry.
