When I was working with a refrrigeration company (until 1996) we used
that product on the drain lines inside walk-in freezers. It was so
superior to regular plastic covered heat tapes that there was really no
comparison. Back then, several A/C-refrigeration supply houses here had
it and sold it by the foot, although the price/ft was about twice as
much as buying it by the roll. Try one of them if you have any near.
