Electric bell-type glass annealing oven is a bell type design where the whole oven raises and the heat is retained in the oven preventing the exposure to excessive heat. Proper annealing is assured by one hour heating time from room temperature to borosilicate annealing point of 585 deg.C. The unobstructed oven bed provides easy positioning of glassware.
Electric boilers use electric heating elements to heat water for in-floor radiant, hot water baseboard and radiator heat systems. It provides an efficient electric heat. These boilers are available as compact wall-hung units. They typically contain two or more immersion-type resistive heating elements mounted in a common enclosure through which water flows.
Electric Box Kilns is a rugged extra heavy duty apparatus. The apparatus have heat seal door construction with door jambs and hinges that are fabricated of steel plate with two heavy duty door clamps, bolt hinges and a peep sight with cover. It has microprocessor temperature controller with digital display, provided with selector switch to shut off automatically at a predetermined temperature or maintain a preset temperature for any required length of time. These are durable, energy efficient multilayer interior lining, up to 7″ thick, consisting of energy efficient 2600o F rated insulating firebricks.
