Expo Engineered Electric Drum Heater
SRX Model, with a 3-position adjustment (full max wattage, 1/2, and 1/4) and also an "infinite" control knob to dial between the max range selected and zero. (PWM? SCR?)
Max load: 3,000 W
Voltage: 240V

Looks like it could easily be dialed into whatever heat input you'd like, and even coupled with a temp controller to cycle on and off. I'm wondering how low the effective turndown ratio is, and if it could be used to stabilize fermentation temps, as well as mash temps. At 3,000 watts, it should be able to get strike water up to temp in a reasonable amount of time as well. If that proves to be unreasonably slow, I could insulate directly over this, and/or add a 2nd heater. I would guess that the heating element goes all the way around the drum for minimal heat flux density, but it's not clear from the information I can find. Heating on the sides of the drum would encourage good circulation in the mash tun as well.
Any experience or expertise is appreciated. Opinions and conjecture also welcome!
