Heating & Cooling Items

High tech comes to Am Sci & Surp!! It is here in the form of a Peltier junction, a thermo-electric device that translates electric power into heat, and perversely, into cool. Apply current @ 3-12 VDC to the gizmo and it extracts thermal energy from one...

To heat what is anybody's guess, but it's a U-shaped heating element, 8-3/8" x 2-5/8" x 1/4" dia with a 107 Ohm Resistance and rubber grommets above the 3/16" wide power terminals. When CJ heated it up to 120F, those grommets got gooey, so he says use...

From Therm-O-Disc, this thermal cut-off switch is N/C (normally closed) by definition. (Thermal cut-offs are what keep your coffeepot from burning your house down.) This one shuts down between 221°F (105°C) and 248°F (120°C) and...

This dipped, nominally 10K Ohm thermistor is on a heatshrunk and tubed 27” lead with a 6mm 2-pin Molex connector. Resistance drops as heat increases (NTC). AC takeout.
