Pressure relief valve (75-5000 m3, wall mounting) ZD-2250 – how to choose the right one
The ZD-2250 is a pressure relief valve without a heating element, designed for wall mounting in chambers with a volume from 75 to 5000 m3. Operating pressure is stated at around 100 Pa, and a temperature alarm sensor is included.
Omitting the heater reduces energy consumption but limits use to chambers with positive temperatures. In a freezer room the same valve would ice up and stop passing air.
When choosing, it is worth confirming the chamber's operating regime – the absence of heating is the most important piece of information here.
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
- Positive-temperature vegetable and fruit cold stores
- Maturing chambers and refrigerated vestibules
- Installations where lower energy draw matters
- Fit-outs with the valve in an easily accessible wall

Ask a questionWhat temperature does the unheated version suit?
The unheated version is intended for chambers at positive temperatures, while the heated versions cover the -30/0°C range. For sub-zero temperatures, the choice therefore falls on the ZD-2230 or ZD-2231.
Can a heating element be added later?
Heated and unheated versions are separate codes. It is safer to choose the right version from the start than to plan a modification.
