4D variant, whereby the outer segments usually remain firmly positioned and only the two middle segments can be opened like a sliding door. An effective solution for distribution traffic with frequent withdrawals in the freezer area so that the entire partition wall does not always have to be opened.


With our longitudinally adjustable GRP trolley, the SHIFT 4D mat curtain can be used over the entire length of the vehicle in order to adapt the loading area to be cooled. The SHIFT 4D mat curtain has four equally large, horizontally adjustable insulation segments and is a very good compromise between loading width, good insulation and easy handling. The seal is made by integrated additional magnets.


Upon request, the mats can also be manufactured with integrated polycarbonate or with rigid foam as a "solid" panel.

Trolley + STORR track

In order to use the SHIFT mat wall along the entire length of the vehicle, the transverse rail is simply screwed to our GRP trolley. The SLIDE trolley required for this is made from a high-strength, but very light fiberglass square tube.

The trolley is designed for the STORR aluminum track for attachment directly above in the corners.

Track stoppers

The use of the wall can be restricted with the rail stoppers *.

3-channel STORR track

The 3-channel STORR track guides the trolleys of the individual mats and ensures that they can be opened quickly and easily.

The locking bolts grip in the defined locking points and fix the mats, on request also available with end magnets instead of locking bolts.


Regardless of whether slide or fixed mounting in the rear area, the aluminum extrusion profile guides the mats easily and with ball bearings. Special positioning aids facilitate fixing in the desired configuration.


We determine the locking position based on the communicated vehicle width. Special constellations are possible if required.

Contact magnet seal

In order to optimally seal the mats from one another, the overlapping areas arranged one behind the other are equipped with contact magnets to keep the mats as closed as possible. This reduces unwanted air circulation to a minimum.


As an installation kit for installation in 30 & 40mm SHIFT SLIDE walls. Voltage either

12 or 24 volts. The air flow rate is around

800 cbm/h.


Operating instructions and a 2-pin socket with protective cap for connection to a spiral cable are included in the scope of delivery. When using fans, we seal the segments with additional expanders instead of the standard magnets.
