Tourbillon Posted June 9, 2017 Posted June 9, 2017 Shimizu mentions using hot water circulating though a heater to dry articles. I have plans to build a small dry box (more like a tower) using a heater core or something similar at the bottom to warm it. Primary use would be drying granulated BP and small stars. Any thoughts on how well this would work? I have a design figured out, just curious if anyone's been down this road. Thanks!
lloyd Posted June 9, 2017 Posted June 9, 2017 Tourb, I use a totally-enclosed "oil bath" heater. It's built like a water radiator, but filled with oil, and equipped with heater elements in the oil to heat it. It's STILL not safe unless re-wired with the proper wiring types, and positioned outside the drying chamber, with baffles and filters to prevent combustible dusts from reaching it. But in your case - if water were the heat-carrying medium - I'd see no reason why you couldn't put the radiator right inside the drying chamber. Lloyd
Tourbillon Posted June 9, 2017 Author Posted June 9, 2017 The heating assembly would be placed a few feet from the dry box. A supply and return line would be run from the heating unit to the dry box. The water would be temperature controlled and adjustable. The way I have it figured now max water temp would be 140 degrees to as low as needed. My thinking is if I set the water temp (120 for example) and barring any outside energy (sun) the box should not rise above that temperature.
Arthur Posted June 10, 2017 Posted June 10, 2017 I like the idea. Perhaps add a baffle to prevent any falling powder/dust from falling onto the heater core for corrosion prevention.
OldMarine Posted June 10, 2017 Posted June 10, 2017 I have an old solar water heating system I removed from a customer's house a while ago and have been pondering a use for it. I think I've found it!
