Engineers working with Asynt have created CryoSyn, a liquid nitrogen generator that removes the need for costly and inconvenient deliveries of liquid nitrogen.

The technology has huge implications for industrial, medical and laboratory applications, removing the need for liquid nitrogen tanker deliveries, which as well as being inconvenient, drive up costs and create potential problems with evaporation and contamination. The control system used gives operators all the information necessary to ensure an efficient and consistant supply of liquid nitrogen and nitrogen gas are always available. From the process to flow and alarms, including automatic operation, trend graphs, service alarm and service records page, there is no other liquid nitrogen system quite like this!

Interest in the generators, which convert gas to liquid via a cooling mechanism, has grown since Homerton University Hospital (United Kingdom) bought one for its fertility centre, where liquid nitrogen is used to freeze and store sperm, eggs and embryos.

Another advantage of the generators, which pay for themselves in two years, is the ease they afford those working in remote or hard-to-reach areas.
