[ HLH-35A/f∞/L82 ]
1.Features of HLH-35
1)HLH-35 can heat up to 900℃.
The ultra-compact halogen line heater HLH-35W/f∞ is a linear infrared heating device that uses a rod-shaped halogen lamp.
The product concept “a small thing.” It is microminiature with condenser miror width 35mm and height 36mm.
The condenser mirror surface adopted a complex curved surface of an ellipse and a circle to overcome the downside due to miniaturization.
HLH-35 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)Used side by side, plate heating is possible.
Irradiation power density reached 35w/cm2 to be used side by side, it is heated up to 1000 ℃ near a wide area.
Even with the same parallel light type, HLH – 60W with a light recovery type hood is superior in case of relatively long irradiation distance or single use.
However, in the case where the irradiation distance is relatively short and plural units are arranged in parallel to perform surface heating, we recommend this parallel light type line heater unit HLH – 35 W / f ∞.

3.Focus and Line size of HLH-35
HLH-35W/f∞/L316 irradiates refractory bricks from a distance of 30mm.
The image below is a thermal image taken with a thermography camera.
The thermal image is divided into 10 areas of the condenser mirror range (316mm x 35mm) of the halogen line heater HLH-35,
Divide the maximum temperature in each divided range by the maximum temperature in 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-35
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-35
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.
