International. The Danfoss TU stainless steel thermostatic expansion valve is celebrating 25 years on the market, a solution for more demanding refrigeration applications.
The company revealed that since its launch in 1995, more than 15 million valves have been sold, a product that has been implemented in different spaces, from refrigerated shipping containers and trucks/trailers to ice machines and ice cream machines.
In addition, the flexible valve design allows customization for a wide variety of applications, sizes, refrigerants and connections. A more recent innovation allows each valve to be OEM/custom laser etched with its exact configuration, ensuring that the correct version is always used. A newly developed low GWP bulb load also helps to significantly reduce CO2 emissions.
The TU features a heat-resistant stainless steel housing and its bimetallic connections make it easy to weld, without the need for time-consuming wet wrapping.
While the valve was first designed in response to the original Montreal protocol agreement, the hermetically sealed construction also makes it ideal for today's refrigerant transition challenges, such as handling A2L refrigerants without leaks. The TU Valve remains a key part of Danfoss' work to qualify the broadest possible component portfolio for all viable low-GWP alternatives.
The TU valve anniversary celebration embodies Danfoss' passion and unique expertise in designing high-end expansion devices, including other iconic valves such as T2 and ETS Hummingbird, which meet the strictest regulatory and application requirements.
"The TU is one of the crown jewels of our thermostatic expansion range," says Arpit Sharma, Danfoss' global product portfolio manager for expansion valves.
"Manufacturers love it for its high degree of quality and reliability exhibited in the field. And, like all Danfoss expansion valves, it has a very narrow set point accuracy, meaning that even systems in harsh environments can also be energy efficient."
"It is fitting that a valve that Danfoss developed to protect the environment is still at the forefront of reducing the direct and indirect impact of the refrigeration industry, today and in the future."
