A NEW high-tech electric furnace released by B&L Tetlow incorporates very accurate vertical uniform heat chambers with a variation of less than 5°C. The furnace sets a new standard in accuracy, according to Tetlow manager Roger Brockway.
Capable of providing continuous heat at 1200°C with intermittant heat at 1250°C, the new model has a working chamber 250mm x 200mm x 395mm deep.
The furnace features a vertical parallelogram door designed to keep the hot face of the door away from an operator and avoid blasts of excessive heat.
A self aligning door seal minimises heat losses and increases the uniformity of heat within the chamber.
The furnace is controlled via a DCV fired solid state relay that achieves a good and tight control.
The relay, in conjuction with a Shimaden FP21 digital controller, is capable of rapid multiple switching in order to prevent temperature over runs.
