Recommendations for installation, operation & maintenance

The T-FIT® Clean range of insulation products is manufactured exclusively from ZOTEK® F42HTLS closed cell Kynar® PVDF foam, produced by Zotefoams plc; the only closed cell clean technology Insulation product designed and manufactured specifically for use in cleanrooms, and used extensively by pharma and biopharm manufacturers to increase cost-effectiveness and eliminate risk within their facilities.

Parts are of a clamshell design comprising ca. 889mm straights, custom-moulded 90° & 45° elbows and equal tees, as well as flat sheets for the safe insulation of valves, reducers, heat exchanges and flanges etc. Straight lengths are supplied with pre-fitted PVDF pressure-sensitive adhesive tape for easy and secure closure; the same tape is supplied and available in separate rolls of ca. 50m.

T-FIT® Clean can be installed with the minimum of fuss, tooling or disruption to any cleanroom operation, and is particulate-free, enabling  installation during production without any downtime or special containment requirements such as tents or hoods.

The high grade PVDF polymer, and the unique closed cell manufacturing process, enable a hydrophobic product that does not require an over-jacket, as well as enabling a clean and inherently bacteria free product (ASTM G21-96) allowing for a minimum cleaning process, utilising standard internationally recognised cleaning products and fluids.

Because of its unique properties and construction, T-FIT® Clean is a fast, easy and hygienic solution for insulating cleanrooms: these same properties enable the constructor an advantage when deciding exactly when to start the insulating process, allowing the benefit of time for early completion of construction, and installing the product in a relatively ‘Clean Room State’.

General Recommendations & Requirements

  • Construction Free area

  • Clean the area and pipes/tubing prior to installation

  • Start installation procedure from Elbows & Tees

  • Prep Elbows minimum 6 hours prior to installation

  • Remove backing tape from straight lengths prior to assembly

  • Use only Zotefoams recommended products when installing

  • On straight lengths snip/slice backing tape every 150mm to reduce excessive wrinkling

  • Apply significant pressure to tape on assembly as ‘pressure sensitive’
