Located at 101 Frazee Ave, Dartmouth, (Halifax Regional Municipality), Nova Scotia, Thermo Dynamics Ltd. (TDL) is a Canadian company engaged in the research, development, production, distribution and installation of solar thermal equipment. Our specialization is liquid, flat plate, glazed collectors with aluminum/copper absorbers. TDL is a fully integrated solar thermal company with the ability to convert raw aluminum and copper into a high technology solar fin with a highly selective surface for superior thermal performance.   Since 1981 TDL has manufactured solar energy products for domestic and exports markets. In 1988, TDL expanded its plant from 2,000 square feet to 12,000 square feet. This was necessitated due to TDL's decision to increase its production facilities and purchase new equipment for manufacturing. One of the substantial acquisitions made during this expansion was the Sunstrip™ solar fin rolling mill.  In 2002, TDL designed and built a state of the art 10,000 square foot manufacturing facility in Burnside Industrial Park, Dartmouth.

The new production facility included a solar radiant floor heating system. To learn more about the design, visit the TDL factory page.  TDL is one of the largest solar manufacturer in North America. Canadian solar technology and the products that TDL manufactures are state-of-the-art world wide. The TDL solar fin is recognized as one of the best solar fins in the world. TDL solar collectors and residential solar systems (derived from the Sunstrip™ solar fin) are competitive with comparable products.   TDL offers a range of products from solar fin for the assembly of solar collector absorber plates, finished solar collectors (glazed, LFP type) and complete solar water heating systems for single-family residential and large-scale commercial applications. TDL has also developed heat exchangers for application in solar water heaters, and the Solar Pump™, a unique photovoltaic-powered pump for solar water heaters and other solar-powered pumping operations.
