Interior: High-density polyurethane (PU) foam, the currently best insulating material on the market

Exterior: Sheet steel in various finishes and designs

The currently best thermal insulation is provided by high-density polyurethane foam, also called PUR.
We use this kind of foam for our sandwich panels which helps you to save money from the very first day. We make sure that cold rooms remain constantly cool at low energy costs. Further features of PUR: Free of toxic emissions, odourless, resistant to chemicals, fungi, and microbes.
Additionally to the proven tongue and groove system, the integrated eccentric turnbuckles provide for precise and fast assembly of the individual elements.

Dimensions and insulation properties

Since it is much more expensive to generate cooling energy than heat energy, insulation is the key for cost savings. According to the requirements there are various panel dimensions to cover all necessary temperature ranges. In case of extreme temperature differences, the insulation should be increased by adding an extra vacuum insulation.

The cooler consists of individual wall, ceiling and floor panels which are securely and precisely joined on site by means of the proven tongue and groove system. Eccentric turnbuckles which are embedded in the foam serve as locking devices for the panels. The interlocking connection of the elements avoids weak areas in the insulation. To ensure good insulating properties even after many years, the PUR foam core needs to be protected against humidity and water vapour. The steel plates on inside and the outside take care of this protection. In this connection, particular attention needs to be paid to precise element and cell corners.

Pfeuffer coolers provide not only cooling features but also meets fire protection requirements (fire class B3 to B1).

OUR EXPERT ADVICE:

Customers who are focused on long-term efficiency are well advised to choose thicker insulation. In the long term, thicker insulation will not only save energy but also money. Furthermore, the thicker insulation will ensure that products are not damaged in case of a power failure.
