Product Specification

This electric heating mantle uses Alkali-free glass fiber as insulation material.The procedure is as follows:1.to make the insulation heating rope you should wrap the Cr20Ni80 alloy wire with this insulation material through the wrapping machine,covering machine,braiding machine.2.then making the heating mantle according to different dimension of flasks with international standards by Pure manual knitting method .

Exclusively using special mold to finalize the design by vacuum filtering the Aluminum silicate wool and to add glue and to dry to make the hemispherical thermal insulator .

Shell is made by one-time injection molding and iron sheet static plastic spray process .with beautiful appearance and anti-corrosion .as adopting spherical heating mode , can make the heating area of the container up to more than 65%, warming up swiftly , high temperature , easy operating , and wear well .

Comes with flask clamp hole(reversal clockwise screw).

This instrument is the ideal instrument for labs of colleges and universities ,science researching institution ,chemical industry to heat in experiment .

Usage

PTHW type heating mantle carry out constant temperature heating by electron voltage regulation . Operating procedure : connect the power supply , open the switch , green light indicates the power , and red light represents heating .when you adjust the knob colckwisely, the temperature will raises at what you need and keep the heating condition, but this needs the thermometer to assist measuring . When first heating , you can adjust the temperature at the high level or the highest level ,when get the temperature needed or the liquid boiling , you can reduce the heating temperature by adjusting the knot to keep warm also can extend the service life . When short time no use ,you can adjust the knot to 0 to stop heating . When long time no use ,please turn off the power .

Attention

1. instrument should be earthed well .

2. At first usage ,it is normal when some white smoke and peculiar smell escapes from the instrument ,because the inner insulation material is made with some oil and other compound. At this time ,you just should put it in the tip-off place .you can use it after a few minutes smoke will disappear .

3. The heating mantle whose capacity is more than 3000ml will make noise like “creak” , this must be related to the different structure of the heating wire or controlled silicon pressure regulating the pulse signal. Please rest assured to use .

4. In case of power off , please check the fuse first at the back and above and see to it that whether it gets changed.

5. Don’t use this instrument without any beaker.

6.There will be inductive electricity passing through the thermal insulation layer and transmit to the shell when the instrument is placed in a humid environment or some liquid run over . so ,earthing is necessary and pay attention to tip -off. If electricity leaking is very serious , please don’t use it .in order to avoid any danger, put it under the sun or dry it in a oven .

7.Long time no use ,please keep it clean and reserve it in a dry and without any corrosion air place .

When there is some change and difference about the specification which is caused by products or products reform related to the specification , pardon that we won’t inform you.
