Cold water reg?

[superkingkong]

Hey guys,

am i right to say that, as long as it's a env sealed diaphragm regulator, then it's classified as a cold water reg?
please correct me if i'm wrong, thanks.

It doesn't have to be a diaphram reg. Atomic regs are piston, and they have a sealed version.

Which reg are you looking at?

Here is what I know about environmental sealing - I don't know what I don't know on the topic, but I trust someone will come set me straight when I go astray.

Some people call diaphragm regs sealed because water does not come in contact with the inside parts. Some diaphragm regs have an extra seal, and those are what I would call environmentally sealed regs. For example, compare the Zeagle Envoy with a DS-V.

A common way to seal piston regs is to pack christolube (sp?) around the piston. Messy, but you might not care if you don't take one apart. One a sealed atomic, for example, you can often see tiny bits of the lube coming out from around the seal.

Sherwood regs are a different story - dry bleed seal system.

So, the answer to your question is probably, as long as their definition of sealed and yours are the same

I hope I didn't screw that up too badly.....

oh, i'm not looking at any reg in particular. i'm just wondering, what is the difference between a normal reg and a cold water reg....

If the reg meets EN250 norm you can rest assure that it's a cold water reg.

Is this mark appears on the manual or the unit itself?

thanks.

That's a new one for me. What's the EN250 norm??

I'm not sure of the designation (EN250?), but there is a European standard for regs that are suitable for use in cold water. The data sheet for your reg ought to give the minimum temperature rating. Often 10C for regs that are not rated for cold water use.

I dive an Apeks XTX 100 which has en environmentally sealed diaphragm and other features to help transfer heat from the surrounding water to avoid freezing up as the breathing gas expands. It is rated for cold water use.

I like my reg, but there are lots of other good regs out there.

Best to my knowledge the reg will have the mark

[superkingkong]

thanks for the info

wondering if the oceanic delta4 is suitable for cold water ? :P
