over-under pressure relief valve
I am looking for a high capacity air pressure equalisation valve for a freezer tunnel.
Nowhere I can find such a valve, has anybody experience with this?

What capacity do you need? Why not mount more little ones?
Is much safer (in case of failure of one big valve)
We always use those of Fermod

Hi Philip
if this is a coldstore the fermod relief valves will be fine. But if you are blast freezing I would sugest making you own relief valves as the amount of these valves required would be just silly.
make up a heated frame and fit this to the freezer wall, with a rubber flap that can be sucked inwards, once the pressure is equalized the flap will self seal. Also I would advise starting the fans in stages to minimise the chance of pulling down the ceiling.
Kind Regards. Andy.
