The Yasui Rotating Burnout series features uniform heat transfer, due to the displacement of air created by the rotating shelves, within the flask chamber.
Accurate temperatures ensure a safe burn-out during stone-in-place casting.
The Variable Power Heating System automatically and precisely maintains set temperatures throughout the cycles, (20 Programs, with 4 Ramps and 4 Holds each). Internal Dewaxing System collects wax outside the flask chamber. The Afterburner device neutralizes all fumes, odors and pollution produced during overnight burn-out cycles. The narrow door design creates minimal heat loss.
Rotating Burnout Furnace #37 (77-0145) is for gold only. Rotating Burnout Furnace #13+ (77-0146) is for both gold and platinum.
Our RBF (Rotating Burnout Furnace) distributes the heat uniformly due to the minimal difference of temperature between the heater surface and the chamber as well as due to the displacement of air caused by the rotation. In this way, all the flasks are heated at the same temperature regardless of distance from the heating coil.
As the door is not wide like normal burnout furnaces, the heat lost is much less and that temperature does not fall much.
One burnout cycle can be programmed in 4 steps. Optimum heating power is automatically calculated and applied corresponding to each temperature zone, so that PRECISE TEMP. CONTROL IS ACHIEVED. Low power is for the beginning steps and higher power for the ending steps. Such a careful control has been developed for preventing flasks from the possible overheat at each step.
The RBF13+ can reach temperature up to 950 centigrade and is ideal for casters who cast both gold & platinum.
Various information is obtained from the control panel, such as present step no., present burning out temperature inside the furnace etc.
Burnout cycle will perfectly proceed by the preset time. For instance, if you plan to start CASTING AT 9:00 AM next day, flasks would be ready at 9:00 AM by presetting time today. Maximum preset time is 9 days 23 hours 50 minutes.
4 kinds of different burnout cycles can be memorized on the controller.
The value of precious stones inside the furnace is beyond comparison with the value of the furnace. RBF13+'s overheat protection device on the front panel can prevent the precious stones safely from overheating. Should the temperature exceed the setting value, the power is immediately shut off.
On power failure during burnout cycle time under automatic burnout mode, present burnout STEP is memorized. And when power is recovered, the burnout cycle can be automatically restored and started from the step number where power failure occurred.
