Turbotec Products

From Graces Guide

1978 Turbotec was established as a wholly owned subsidiary of Spiral Tubing and sold its first coaxial condensers to the heat pump industry and expanded the applications of its tubing into new exchangers for the biomedical industry and bendable connectors for plumbing applications.

In 1981 Spiral Tubing Corporation merged into Thermodynetics, Inc. The company conducted an initial public offering (TDYT) on July 16, 1981. The $3.3 million raised allowed the company to construct a 40,000-sqaure-foot facility in Windsor, Connecticut.
