Lower temperatures and cut emissions


New Brisbane-based system changes the way refrigerated vans and trucks cope with tougher emission and safety regulations

By Gary Worrall

A new system developed by Brisbane company Crisp Air is changing the way refrigerated vans and trucks cope with tougher emission and safety regulations.

Managing Director and Chief Executive of Crisp Air Rob Hooper says the new system captures excess energy from the engine and stores it to be used when the engine is switched off.

Hooper says the system can either store the energy as electricity or as chilled air in a solution to absorb heated air.

Hooper says the systems have been tested with an ambient temperature of 38 degrees on an empty van intended to reach -20 degrees, which is actually harder than cooling a loaded unit.

While the systems are currently only offered on vans of up to 12 cubic metres due to electronic management system restrictions, Hooper says the system will eventually run on any refrigerated unit.

Although the system currently uses the vehicle’s excess energy, Hooper says solar power will be used in the future.

Technology is not yet efficient for use on trucks or vans, with storage cells a key issue to be overcome.
