Pressure relief valve (75-5000 m3, -30/0°C, ceiling mounting) ZD-2231 – how to choose the right one

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.

Where it works

  • Chambers with every wall fully fitted out
  • Freezer rooms with heavy trolley traffic along the walls
  • Installations planned together with ceiling-level routing
  • Facilities monitoring temperature on a controller

Ask a question
Can the wall version be mounted in the ceiling?

The manufacturer keeps the two versions as separate codes, the ZD-2230 and ZD-2231. Since the distinction is made in the catalogue, this is not a swap to make on your own.

How is condensate drained when mounted in the ceiling?

The catalogue datasheet does not describe this. It is a question to settle at the installation design stage, together with the routing of the power cables.
