ers. The TWISTO/N-B connection kits are simple and safe to use, yet
faster to install and more cost effective than conventional systems. They
can be used with BARTEC BACAB FT trace heaters in fixed equipment
heating systems for multiple applications (e.g. heating of pipes, roof and
gutter de-icing etc.).
