I was going to ask you guys that very question, is it worth trying to keep the sub warm.    My understanding is that the absorbent actually generates heat.  Maybe once it is going it is fine by generating its own heat.   Hank

 Sean,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.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.I will likely need both scrubbers going with a passenger.Hank
