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.
Doing without heating lowers both the price and the power draw, but narrows the application to chambers with a positive temperature. In a freezer, the same part would ice up and stop letting air through.
The catalogue name here has no temperature range, unlike the heated versions. That is a cue to confirm the chamber's operating regime when choosing - 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 manufacturer does not give a lower limit for this item, but does list the heated versions as designed for -30/0°C. For sub-zero temperatures, the choice therefore falls on the ZD-2230 or ZD-2231.
Can a heating element be added later?
The catalogue splits the versions into separate codes and does not describe retrofitting. It is safer to choose the right version from the start than to plan a modification.
