In brief
Prices and stock levels are in the B2B shop. Sets of cold room fittings are put together to order.
The ZD-2231 is a pressure relief valve with a heating element, designed for ceiling mounting in a chamber with a volume from 75 to 5000 m3. It works at a pressure of around 100 Pa and has a built-in temperature alarm sensor.
Ceiling mounting is chosen where the walls are entirely taken up by shelving, or where a wall passage would fall somewhere exposed to trolley impacts. A valve under the ceiling is simply out of the way of traffic.
This convenience comes at the cost of service access. Inspecting a part mounted under a freezer's ceiling needs a lift or a ladder, and often fencing off the area for the duration of the work.
How to match the fittings to the panel thickness and the weight of the door – we explained it in the selection guide for this category.

Ask a questionThe wall and ceiling versions are separate part numbers: ZD-2230 and ZD-2231. Swapping one for the other is not something to do on your own – for ceiling mounting, order the ZD-2231.
Condensate drainage is settled at the installation design stage, together with the routing of the power cables.
