Your Challenges

Heat exchangers of all types and sizes form an integral part of any industrial operating facility and require periodic servicing to restore heat transfer performance and normal production levels.

How We Support Your Business

We have substantial experience in planning, managing and executing all aspects of heat exchanger maintenance from the pulling of bundles and expert cleaning of them to providing all manner of repairs, reinstating the exchangers back in service and leak testing them to ensure asset integrity. This one-stop approach enables our customers to handover the total work scope to one contractor without any interface issues.

The CR3 Difference

We continually invest in the latest equipment and technology. As evidence of this, we are one of the only contractors in Asia to have bundle pullers capable of extracting bundles up to 125 tons in size.
