About Us

Twenty years ago, a Dutch entrepreneur established a company called On-Line Cleaning BV which focused on cleaning Steam Boilers while they are in operation. On-Line Cleaning BV grew to have operations in the rest of Europe, the United States of America and Asia.

It has 28 offices in America and a presence in Germany, Italy, Spain, Denmark within Europe; and operates in Singapore, Malaysia, Thailand and Australia. Subsequently the company was and its patents was sold to a Consortium of American and European investors.

In 2014, a similar operation was established in South Africa together with local investors which operates as Xstream Cleaning Technologies (Pty) Limited also known as (XCT).

We are experts in controlled detonative cleaning in the centre of the contaminated/build up areas. This allows removal of fouling and other deposits immediately, to increase the installations efficiency. Safe and secure operation are crucial fundamentals to making sure clients plants operate effectively and efficiently.

Industrial installations, mines, power and cement plants experience daily challenges in keeping production at consistent levels. XCT is a leading provider in Africa of industrial detonative cleaning solutions. The methods ensure the safe and effective cleaning and de-fouling of boilers, combustion chambers and other industrial equipment, while the plant remains fully operational.

XCT cleans boilers as well as remove clinker build-up while the industrial boiler is running on full load. Due to this technology, a power station can avoid huge and costly downtime. The equipment is developed and assembled in-house and is therefore exclusive to XCT.
