While water is an economical and thermodynamically efficient heat transfer fluid, it has several important limitations, including corrosion potential and lack of freeze protection.
Properly inhibited heat transfer fluids help overcome these challenges while maintaining the beneficial heat transfer properties of water. Properly formulated fluids provide an effective balance of corrosion protection, freeze tolerance, and long-term system performance.
Heat transfer fluids can be manufactured using inhibited ethylene glycol, inhibited propylene glycol, inhibited ethyl alcohol, or inhibited 1,3 propanediol depending on the application requirements.
Houghton Chemical manufactures and supplies a full line of heat transfer fluid solutions, including SAFE-T-THERM®, WINTREX®, and GeoSafe®, serving HVAC, industrial, food and beverage, water treatment, geothermal, data center, and mission-critical cooling applications.

Fun Facts
Did you know that when watching your photo magically appear, it was a partly made possible by Houghton Chemical?
Houghton Chemical was Polaroid’s sole provider of photograph solvents. Due to Houghton’s quality procedures and safety standards, Polaroid would not accept a solvent delivery from any other company.
Did you know that the Houghton logo was one of the early designs of Joe Selame? Joe lived in Chestnut Hill, MA and was the neighbor of Houghton’s 2nd generation president, Proctor Houghton.
Joe went on to design many popular images for companies such as: Goodwill Industries, CVS Pharmacy, and Eastman Kodak.Â
At one time the Houghton Chemical tank farm, like most others, was painted white. In 1968, Joe Selame, designer of the Houghton logo, proposed the idea for a colored tank farm.
Proctor Houghton and fellow employee Barbara Daly, spent hours determining each tank’s ideal color.
The pastel tank farm has been a historic landmark ever since.
Did you know that since 1960, Houghton Chemical has been doing business at 52 Cambridge Street in Allston (Boston), MA?
We have seen many changes in our immediate neighborhood during the last 50 years.
The DoubleTree hotel was built on the old Coca Cola plant. The Mass Turnpike and exit 18 was constructed outside our window. The CSX rail yard, once the hub of rail transportation in Boston, was shut down and dismantled.
Did you know that over the years Houghton Chemical has helped make sure the flights out of Logan airport run on time? During the winter season, Houghton Chemical has been on call 24 hours a day to make sure deliveries of wing deicer arrive on time to Logan airport.
While the rest of New England is digging out from yet another snowstorm, Houghton Chemical is hard at work.
Do you know where Houghton Chemical’s product names come from? Both our GeoSafe® and SAFE – T – THERM® brand names are the result of an employee contest.
WINTREX® was an old antifreeze name purchased from Monsanto and reinvented to create one of the products in our Heat Transfer Fluid department.
Pah|Nol® is the first trademarked Houghton Chemical brand name. It was created in the 1950’s by Phillip Alan Houghton.
The first three letters, ‘PAH’, represent our founder’s initials.
The ‘NOL’ comes from the last 3 letters of methanol, which was the principle ingredient in automotive antifreeze at the time.
