Danfoss Marks 50 Years For T2 Expansion Valve

Danfoss recently marked the 50-year anniversary of production of its T2 expansion valve. First manufactured and delivered to customers in 1966, the T2 has served as a fundamental part of Danfoss’ expansion valve program and proven itself as a staple in a variety of refrigeration and air conditioning applications worldwide.

“In the years since its initial release, the T2 has been a game-changer for Danfoss, thanks to its tremendous success in the market,” said Stephen Gugliotta, senior vice president, automatic controls at Danfoss. “No valve has surpassed or outperformed the T2 due to its energy efficiency, quality, and reliability. Danfoss estimates the T2 has saved approximately 157,000 GWh in the thousands of applications where it has been installed. To put this in perspective, the energy saved could power Italy for six months, Denmark for nearly a year, or Argentina for over a year.””

The T2 remains the single most produced Danfoss expansion valve with production locations in Denmark and China. Features and benefits include:

  • large temperature range that covers both refrigeration and air conditioning systems;
  • interchangeable orifice assembly for easy stocking and service; and
  • stainless steel bulb and Danfoss patented bulb strap for fast and easy installation.

With the T2’s history as a safe and reliable choice for Danfoss customers, it has served as the foundation for further expansion valve innovation. The TU expansion valve, launched in 1995, was the first of its kind made of stainless steel. Incorporating innovative bi-metal connectors that eliminate wet-wrapping during installation, the TU is a compact and lightweight valve.

“Danfoss has developed many innovative products, technologies and solutions in its endeavor to help meet the world’s growing challenges in infrastructure, safe food supply, energy efficiency and climate-friendly solutions—and the tale of the T2 has been a vital contributing factor,” said Gugliotta.
