Is this statement also good for Trimix (TX12/45) at 330 under the above condition?. This is in consideration of the specific heat of the gas mixtures. >> No, Greg, that is not what I said. In fact, an MK10 set to 145psi at 200 feet under ice would would have a higher potential for freeze-up than I would be comfortable with. My choice would be an MK14 set to 125psi. As for the differences with tri-mix, you tell me. You are the thermal engineer. Safe diving, Dale -- Send mail for the `techdiver' mailing list to `techdiver@aquanaut.com'.
