Cooling tunnels

Back to overview

POWER PLUS

In POWER PLUS cooling tunnels, all kinds of biscuits and chocolates are guided through a number of cooling zones via a conveyor belt and cooled. The POWER PLUS has the same specifications as the POWER III but is also easier to fully clean. This via hinged bottom plates.

All tunnels are custom made. The length of the cooling tunnels is determined by the speed of your transport and the required cooling time of your product(s).

Our Prefamac Benefits

The correct cooling

With more than 30 years of experience, Prefamac can guarantee you the right cooling for your product: the number of zones and their individual capacity, the ideal energy-saving insulation, an air or water-cooled system, convection cooling or radiation cooling, and also the possible options that increase the ease of use. And after 20 years, our tunnels still require a minimum of maintenance, due to their extremely strong construction.

We are TOP in customization

Do you have certain requirements for a specific working height, or inclined and descending cooling units, a non-standard location for the drive, or a very long cooling tunnel at a top speed? We are happy to help you with our experience in co-design and co-creation.

Everyone his or her choice

The POWER PLUS is available in all possible carpet widths: 620-820-900-1050-1200-1300-1400-1500 and 1600 mm. For 400 or 500 mm it might be better to choose a different type of Prefamac tunnel. And do you want to extend your tunnel into the future? This can also be discussed with Prefamac.
