1.Features of HLH-30
1)HLH-30 can heat up to 1000℃.
Ultra-compact halogen line heater HLH-30 is a condensing infrared heating device that uses a rod-shaped halogen lamp.
The product concept “a small thing.” It is microminiature with condenser miror width 30mm and height 34mm.
The condenser mirror surface adopted a complex curved surface of an ellipse and a circle to overcome the downside due to miniaturization.
HLH-30 is being done small to the limit while maintaining high performance, so it’s extraordinarily small, the best heating temperature is about 1000 ℃.
2)A perfect clean heating is realized, heating in a clean room or vacuum chamber is also possible.
The water-cooled type can be used by a vacuum chamber.
When it is placed in a vacuum chamber, there is gas emission which is slightly from inorganic glue in an early stage, so vacuum treatment is needed beforehand.

3.Focus and Line size of HLH-30
If HLH-30 is separated from a focal length (20mm), it can also perform heating which gave width.
Irradiation intensity is even, but the temperature of the center of the higher heat of the peripheral portion is run away.
Refractory bricks are irradiated with HLH-30W/f30/L152 from a rated distance of 20mm.
The image below is a thermal image taken with a thermography camera.
The thermal image is divided into 10 parts of the condenser mirror range (152mm x 35mm) of the halogen line heater HLH-35,
Divide the maximum temperature of each divided range by the maximum temperature of the entire range to quantify the temperature distribution of the heat-resistant bricks.
Since it is a rod-shaped lamp, the irradiation intensity is uniform, but the heat incident on the object to be heated is dissipated to the outside, and the temperature in the center, where heat dissipation is small, rises.
4.Temperature rising time of HLH-30
【Please note】
In infrared heating, the heating temperature changes depending on the infrared absorption rate of the object.
When it is irradiated for a long time, it becomes high temperature.
5.Voltage and lifetime of HLH-30
As shown in the above figure, if user lower it by 10% from the rated voltage, design life will be lengthens to 3 times.
If user lower it by 20% from the rated voltage, design life will be lengthens to 9 times.
