Cryofridge, a Frappa group brand, has taken a pioneering step in the onboard refrigeration market by entrusting Crouzet Automation with the control of its indirect nitrogen cryo-units.

The coach-building group Frappa supports haulage professionals by providing all their refrigerated transport equipment needs. This French company is constantly updating its offer for a road haulage market that is still feeling the effects of the credit crunch and suffers from a poor image as a noisy polluter that nonetheless provides an essential service. Combining vision and innovation, it capitalises on a wealth of experience in this field to produce ever more ingenious, greener solutions.

In 2010 the Frappa group, via its Cryofridge brand, diversified into indirect nitrogen refrigeration with the Silencio system. The principle: nitrogen circulates in an exchanger and cold is distributed through the insulated space. The benefits: the system is quiet (all electric), meaning that deliveries can be made in urban areas both day and night without disturbing the residents. It is also eco-friendly (no CO2 emissions), unlike more conventional refrigeration systems that use fuel to power the refrigeration unit, which runs with a fan and a heat engine. Cryofridge uses this technology in its single or multi-temperature trailers (one or two compartments in a single trailer), and generates both “positive” refrigeration (keeping food fresh) and negative refrigeration (freezing and deep freezing).

To manage this system, Cryofridge was until recently using an electronic card developed for the aerospace industry, which was rigid, complicated to use and to program. The development team was keen to migrate to a more flexible solution that would be easier to program and set up. They also wished to not only provide temperature control and nitrogen level functions, but also offer drivers a user-friendly, intuitive human-machine interface.
