New video: This is us

Who is SANHA? This simple question is now answered by a new company video showing the highlights of the Essen-based manufacturer of piping systems and fittings in English. The video can be found at

Piping Systems for Sub- and Transcritical Systems

Sanha offers two different piping systems for cooling and refrigeration which cover all requirements in the sub-critical and transcritical area: The NiroTherm stainless steel press system for glycol applications and the RefHP high-pressure brazed fittings for CO2 cooling systems.

Thermal expansion: Water's unique properties

Water does not behave like other liquids. It is the only liquid to expand when it changes phase, taking up more space when it freezes. But people are not always aware that it expands again in its liquid phase, at temperatures above 4 ℃. This can lead to movement or "thermal expansion" of the piping system. We show you what you need to keep in mind.

Second construction phase for the Biology Department

Preserving Food, And The Planet

From fridges and freezers to air conditioning systems and heat pumps, scientific breakthroughs in cooling technology have changed the way we live. But progress has come at a cost. It wasn’t until the 1980s that scientists discovered that CFCs, once thought the ideal refrigerants, were depleting the ozone layer. A few years later, their popular...

Dorian - Helping to Preserve our Naval Heritage

In May 1940, as more than 338,000 troops lay trapped on the beaches of Dunkirk, the British Government orchestrated their rescue, codenamed Operation Dynamo.
