  • Contract was completed in under 1 day.

Tube Tech Comment

Scott Donson, Technical Sales Manager: “Our cleaning techniques are ideally suited to clients who not only need to clean equipment as quickly as possible, but in addition achieve cleanliness standards which equal or exceed those of others who take longer. We were pleased to have been able to solve this cleaning challenge.”

Client Comment

Manager: “I was very pleased with the work that was carried out. Your team were well prepared and embraced our site rules and procedures after the induction with no fuss. I think we found around 25% of the tubes hard plugged at the bottom. Your kit easily cleared what was there (carbonized material) and we have increased the flowrate through the exchanger by around 80m3/hr.”
