How cold you talking about? I dive mine in 38-40 (Fahrenheit- sorry, don't know metric conversions!) water all the time w/ the stock Apeks first stages- no problems so far!

Apeks DSTs with enviro deal would be my choice.
And I dive pretty cold. Remember a Rebreather reg is less affected by large gas volume cooling like OC regs are so I would think most regs will work OK in cold water.

Dean,

Any environmentally sealed Apeks that can be modified for fixed IP to work in a constant flow configuration.

DS4's can be had for cheap...

Can't do much better than the stock Apeks DS4s.

DS 4 works well for me, and i dive in 4 degree C cold water.

Does anyone use scuba pro first stages ,can the ip be disabled on them .. how ?

I use some Scubapro MK25's on my stages.

The IP is controlled by adding or removing these little metal shims and all you can do is get close on the IP.

The IP on the MK-25 has spiked on me a couple of times...huge spikes! so I personally would never use one on my Rebreather!!

I would sell the scubapro regs and get you some Apeks. The IP is easier to set and they nice solid regs.

I use scubapro Mk20/25's and Mk2's for everything..OC and CC. Work great in cold water (have had them under ice, etc). Being a piston reg, you can't fix the IP, at least very eaasily. I use a stock Mk2 piston feeding a needle valve and it works great.
