My understanding is that the absorbent </span>actually generates heat. Maybe once it is going it is fine by generating its own heat. </div><div id="yui_3_16_0_ym19_1_1487190620308_4967">Hank</div> <div class="qtdSeparateBR"><br><br></div><div class="yahoo_quoted" style="display: block;"> <div style="font-family: HelveticaNeue, Helvetica Neue, Helvetica, Arial, Lucida Grande, sans-serif; font-size: 12px;"> <div style="font-family: HelveticaNeue, Helvetica Neue, Helvetica, Arial, Lucida Grande, sans-serif; font-size: 16px;"> <div dir="ltr"><font size="2" face="Arial"> On Wednesday, February 15, 2017 11:37 AM, hank pronk via Personal_Submersibles <personal_submersibles@psubs.org> wrote:<br></font></div> <br><br> <div class="y_msg_container"><div id="yiv9051897145"><div><div style="color:#000;background-color:#fff;font-family:HelveticaNeue, Helvetica Neue, Helvetica, Arial, Lucida Grande, sans-serif;font-size:12px;"><div id="yiv9051897145yui_3_16_0_ym19_1_1487183234485_4559">Sean,</div><div id="yiv9051897145yui_3_16_0_ym19_1_1487183234485_4559">You were correct, I pre heated the sub to 20C and the performance improved, after 10 minutes or so the scrubber performance really improved. When I travel to my dive site, I will turn on the scrubber while the sub is hot inside and it can get warmed up before I dive. I put a PWM controller on the fan but it performs best at full speed.</div><div id="yiv9051897145yui_3_16_0_ym19_1_1487183234485_4559">The new Radial scrubber alone keeps up just fine (1700 PPM ) with the sensor at the front of the sub and the circulation fan running about 1\4 throttle.</div><div id="yiv9051897145yui_3_16_0_ym19_1_1487183234485_4559">I will likely need both scrubbers going with a passenger.</div><div id="yiv9051897145yui_3_16_0_ym19_1_1487183234485_4559">Hank</div></div></div></div><br>_______________________________________________<br>Personal_Submersibles mailing list<br><a ymailto="mailto:Personal_Submersibles@psubs.org" href="mailto:Personal_Submersibles@psubs.org">Personal_Submersibles@psubs.org</a><br><a href="http://www.psubs.org/mailman/listinfo.cgi/personal_submersibles" target="_blank">http://www.psubs.org/mailman/listinfo.cgi/personal_submersibles</a><br><br><br></div> </div> </div> </div></div></body></html>
