Laboratory furnaces LE -Economy Line经济型马弗炉LEApplicationLE lab furnacesare suitable for testing technology where the exact distribution of temperature, the 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. This especially applies to 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's rust-resistant coating ensures the long life of the furnace. The heating spirals are placed in tubes of silica glass. This partially protects the spirals from corrosion by aggressive materials which can be released during use. A programmable controller and the master switch are located on the front side of the furnace. Included in the standard design: -          manually opening of the doordownwards  -          HT60B controller-          heating elements in silica tubes-          slide valve for opening the supply of air-          airing chimney Accessories for additional charge: -          controller HT 40P-          exhaust ventilator with draft damper (for HT 40P controller)-       RS 232 or RS 485 interface for connection with PC 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-         主要结构描述 -优质不锈钢外壳，框架结构-门由耐火材料填充、坚固耐用-高温室由绝缘的耐火材料组成-电热丝被石英管包围，并安装在电炉两侧-门上加厚矿物纤维耐火层-烟囱被安装在炉子后侧-加热石英管包埋在耐火材料中-门上装有安全开关-采用单相电源-冷风扇装备的熔炉- K型热电偶被安装在背面 标准设备包括 - HT60B控制器-手动向下开门 可选附件（需要另行计费） -电脑连接端口R 232/485-排气风扇或者烟囱-监控软件和温度循环的记录-气体保护装置  优点-实现不锈-吸引人的设计-顶部绝缘材料(低功率消耗,在被要求的温度上快速开始)-可编程的高精确度的温度控制-固态继电器SSR (流畅和无声的运转,周围机械装置的最小干扰)-完美的车间操作，保证硬件和使用中的安全  可选型号： 类型控制器最高温度容积外部尺寸(wxhxd)内部尺寸(wxhxd)输入重量电压LAC °CLmmmmkWkgVLE 05/11HT40B11005470x330x455170x130x2301,8kW18230LE 09/11HT40B11009,4490x370x515190x170x2902,3kW23230LE 15/11HT40B110014,4550x370x565250x170x3403kW30230LE 05/11HT60B11005470x330x455170x130x2301,8kW18230LE 09/11HT60B11009,4490x370x515190x170x2902,3kW23230LE 15/11HT60B110014,4550x370x565250x170x3403kW30230
