Cryogenics and Industrial Gases

Liquefied gases are used in a wide range of applications, including metal processing, medical technology, electronics, water treatment, energy generation, and the food industry, among many others. Today, more and more of these industrial gases are delivered to customers in liquid form at cryogenic temperatures, enabling them to be stored on site for later use.

In order to maintain their extremely low temperatures, cryogenic liquids are often stored in double walled tanks consisting of two cylindrical vessels, a stainless steel inner tank (the pressure vessel) and an outer jacket in carbon steel. The air in the space between the inner and outer vessel is known as the annular space, which is evacuated by means of a pump to create a vacuum and provide vacuum insulation.

The vacuum insulation is arguably the most critical element in a cryogenic tank, making vacuum gauges, vacuum measurement, and vacuum control a top priority. Televac® offers a wide range of analog and digital vacuum gauges for cryogenic applications including our 2A thermocouple micron vacuum gauge, our 2A VacuMini thermocouple micron vacuum gauge, the small and portable Vacuguard vacuum controller, and the easy to use MX2A active vacuum gauge.
