Pressure relief valve (16 W, 0/-30°C) ZD-21216 – how to choose the right one
The ZD-21216 is a pressure relief valve for a 220-240 V supply with a 16 W draw, intended for operation in the range from 0 to -30°C. The manufacturer allows it to be mounted in either the wall or the ceiling of the cold room.
A draw of sixteen watts sets it apart from the other valves in this bracket, which run on forty watts within the same temperature range. For a device powered around the clock, the difference translates directly into the annual bill.
Freedom to choose the mounting plane can be decisive in cold rooms where the walls are taken up by shelving or the condensing unit. Wall-only items then force a redesign of the interior.
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
- Freezer rooms operating in continuous mode
- Installations where only the ceiling plane is left free
- Sites that account for energy consumption per device
- Replacing a valve with a higher power draw

Ask a questionIs 16 W enough to keep the valve from freezing up?
The manufacturer gives the power draw and the operating temperature range, but does not break the consumption down by individual functions. If the cold room goes below -30°C, the selection needs to be confirmed before purchase.
What volume is the ZD-21216 suitable for?
The datasheet does not give a volume range, unlike the ZD-2220 or ZD-2230 families. When selecting, it is worth providing the cold room's dimensions so we can match it against items specified by volume.
