Laboratory Furnace LE

实验室电炉 LE

Application：

LE Furnaces are suitable for laboratory testing in which exact temperature distribution， controlled increase and decrease of temperature， and controlled cooling are important， and where it is also desirable that the heating elements are not in the interior space with the samples. The LE is especially good for heating material for the heat treatment of metal， various tests of sintering， calcination， determination of the softening point or of material sintering， combusting samples， enamel firing etc. The LE standard design features heating spirals which are placed in silica glass tubes to protect the spirals from corrosion by aggressive materials which can be released during treatment of the charge. It also includes an HT60B controller and a slide valve for opening the air supply， an airing flue and a special rust-resistant coating.

Standard design of the LE furnace includes:

- manual door opening downwards with a safety limit switch

- HT60B programmable controller

- heating elements inside protective silica tubes

- slide valve for opening the air supply

- airing chimney flue

Optional accessories for additional charge include:

- upgrade to PID controller HT 40P

- exhaust ventilator with a draft damper (only with HT40P controller)

- enhancement of the controller with RS 232 or RS 485 PC communication line (Monitoring SW Ht Monit optional)

Benefits of the LE furnace line include:

- reduced jacket temperature

- dynamic temperature curve regulation at DIN 17052-1

- low power consumption

- very reasonable price

用途

-用于所有种类的实验室测试，如医疗、口腔病学、卫生学、陶瓷学、玻璃制作等。熔炉适用于一些技术测试，这些测试注重温度的分布、温度德控制和发热元件和样品同时在内部空间时的冷却控制。熔炉特别易于进行在金属的加热过程对物质的加热、不同的烧结实验、煅烧、软化点的确定、物质的烧结、样品的燃烧和彩烤等等
