For heat shrink of wire harnesses, use the Halogen Ring Heater HRH Series.

1. Easy heating, high temperature with the hood! The conversion efficiency from electricity to radiant energy is high, and within the halogen lamp hood, it can reach high temperatures of 650°C. 2. Instant heating, reduction of heating time. HRH transmits a large amount of heat at the speed of light, allowing for miniaturization of the equipment and shortening of heating time. Previously, idling took 30 minutes, but this can be reduced to zero. There is no time lag in heating, eliminating wasted waiting time. Since the temperature rises quickly, the power can be turned off during idle times. This saves energy and reduces electricity costs. The electricity usage cost is calculated as 2kw x 0.5h x 12.16 = 12.16 yen per day. Over a year (operating 250 days), this results in a cost reduction of 3040 yen. Additionally, the annual CO2 emissions are reduced by 100 kg! *The electricity usage cost unit is calculated at 12.16 yen/kWh. *The CO2 emission factor is calculated at 0.4 kg-CO2/kWh. 3. Heating through glass is possible. Quartz glass has almost no absorption in the visible light and near-infrared range, with a transmittance of 93%. There is only 7% reflection. Heating operations can be performed even in a vacuum or inert gas atmosphere through the glass.

Detailed information

Heat shrink for wire harnesses Issues There was no good method for heating from all around, which was problematic. ⇒ Improvement points Shrink heating was done using a halogen ring heater. Since it heats from all around, it shrank beautifully. Yield improved and rework was reduced.
Resin rod welding Issues There was no good method for evenly heating from the surroundings, which was problematic. ⇒ Improvement points A halogen ring heater with a ring hood was used. The resin rod inserted from the inlet was welded on the opposite side.
Heat Staking and Shrink Fitting of Cylindrical Workpieces Issues There was no good method for uniformly heating from the surroundings, which was problematic. ⇒ Improvement Points A halogen ring heater with a ring hood was used. This allowed for uniform expansion and smoother fitting.
Soldering of cylindrical workpieces Issues There was no good method for heating circular shapes at high temperatures, which was problematic. ⇒ Improvement points A halogen ring heater with a ring hood was used. Heating was achieved quickly and smoothly.
Heating the upper part of the test tube Issues There was no good way to safely observe the heating process, which was problematic. ⇒ Improvement Points Used a halogen ring heater with a ring hood. Was able to heat the test tube safely. Increased research speed.
Heating of Pipes Issues There was no good method for heating pipes to high temperatures. ⇒ Points for Improvement A halogen ring heater with a ring hood was used. It heated up quickly and became smoother.
Heat sterilization Issues I was struggling because there was no good method for dry sterilization. ⇒ Improvement points I used a halogen ring heater with a ring hood. Since it only needs to be inserted from the inlet, the work speed has increased.
