- Light thermal mass heater: Comparing to conservative type brick furnace, there is lots of reduction in heat-up time, power consumption, and footprint. - Stable gas generation: Tube type retort integrated in round heater can generate cracking gas stable. - Safety feature: Excess temperature protection, over pressure, thermocouple burnt alarm, etc can maintain the system safe. - Save footprint, easy operation: Operation switch install on front panel. Insulator got thinner and can realize less footprint.
