He said no need because the scrubber gives off enough heat and in the Arctic the DW's stay at 78 or so degrees from body heat and heat from the scrubber. I mentioned that I need to warm up my scrubber before a dive. Phil says it is likely because I am not using Soda Sorb brand. The DW's do not need to run scrubbers until the hatch closes. </div><div id="yui_3_16_0_1_1490748517635_2547" dir="ltr">Hank</div></div></body></html>
