Total Engineering of Light and Heat by Miyakawa Such needs as “Raise temperature in a short period” or “Make the heating space compact” are growing in recent days and it is “the Halogen Heater (near infrared)” that realizes these targets. Miyakawa has been working for over 15 years on the research and development of the “Halogen Heater” to turn it to practical use for the industrial energy. Now, we feel proud of being able to provide with its technology and knowhow accumulated for long years.

FEATURES 1> High Efficiency

4> Long Life

More than 85% of input electric power is converted into the infrared. The reason for this high efficiency is that the radiated energy from directly heated metal at high temperature is utilized without the generation of useless energy.

Halogen heaters are designed for long life – more than 5,000 hours at an average rate except certain types - due to halogen cycle effects (the function that reins in wearing of tungsten heater by sealing halogen gas in). Reduction of output to the life end

2> Concentration of Energy The energy can be concentrated by optical methods

point is as low as several percent. Thus, handling is easy and economical.

5> Heating in vacuum There are types which can be installed in vacuum. When using the out-of-vacuum types, if the container Time[sec.]

As tungsten heater with low heat capacity is used, heat-up and cool-down are almost instantaneous and output control is done electrically with perfect freedom. And as concentration and diffusion of energy are possible by optical methods such as mirror and lens, this is highly controllable heat source.

In narrow places or places where other heat sources are hard to bring in, the installation is possible. And handling is very easy, because structure and function are simple.

Option Black coating type (far-infrared ray heater) Coated by special ceramic coating on the surface of heating element, this type converts almost 100% of visible radiation output and 70∼80% of near and middle infrared output to far-infrared ray. Compared with the amount of far-infrared ray generated by regular halogen heaters (clear type), the amount is 2 ∼3 times and peak output wave length becomes 3µm∼4µm.

Vacuum specification QIR heater As ceramics or cement are used on the base portion of normal QIR heater, gas and fine particles are discharged when used in vacuum, causing certain troubles.

QIR

heater

is

constructed without using these materials. As a result, the heater can be used in vacuum without fail. However, as service conditions vary depending upon degree of vacuum and temperature of QIR heater’s sealed part, if the heater is used under specific condition, please consult with the Manufacturer.

White coating type (equipped with reflection coating) By white-coating outside surface of heating element, infrared is emitted effectively in a single direction. By doing this, reflector and other attachment can be omitted, then downsizing and space-cutting of system can be

realized.

Near infrared ray

(1,000µm) are collectively called infrared ray. As shown in the left figure and the following table, they are divided into three categories. These three, that is, near, middle and far infrared rays have major characteristic respectively.

Relative radiation strength (%)

Middle infrared ray

Near infrared ray (i.e. halogen heater) is the highest in energy efficiency and its big characteristic is that its energy is concentrated to around 15J/cm2. Therefore, high temperature

Far infrared ray

heating is possible and the compact system can be composed. Black-coating tube, an option of halogen heater, radiates far infrared ray effectively and its buildup time is very quick, several tens of seconds, compared with general far infrared rays. That is a big advantage in use. Wave length (µm) Group

CAUTION about safety of the halogen heater

Do not cover halogen heater in use with flammable object (paper, cloth or plastic for example) or move them closer to halogen heater.

It may cause a fire.

Do not drop, scratch or direct unreasonable power to halogen heater.

Broken pieces of glass

may fly apart, causing physical injury because inside pressure of halogen heater is high. Use confirmable appliances such as socket, electric source and others.

In case of

nonconforming, it may cause overheating or short life. If lighting direction of heater is designated, never fail to use the heater in designated direction.

Otherwise the appliance may overheat or be transformed, causing extreme short

life. Never fail to turn the power off when installing, uninstalling, checking or cleaning the heater. Otherwise, it causes breakage of the heater or electrical shock.

As halogen heater is at high temperature while it is lighting or immediately after switched off, never tough it with bare hands.

It causes burn injury.

Do not touch halogen heater directly with bare hands even in cold condition.

If lighting it up

with hand grease on its surface, glass deteriorates and the heater life becomes short.

If the

heater becomes tainted, wipe it out cleanly with alcohol etc. and use it (When handling halogen heater, use clean gloves.) In order to prevent contact failure, dropout from fixture or fall-down, install halogen heater surely to socket or mounting terminals. Do not use halogen heater at more than specified voltage.

Using at more than specified

voltage will result in extreme short life or heater may be broken depending on conditions. Check if socket and contact portion are not damaged and confirm there is no deformation, rust or taint.

They may cause faulty lighting or cause of overheating.

Do not use where water drop or rain falls. dusty surroundings.

Do not use in high temperature, high humidity and

They may cause overheating and breakage.

Rush current Resistance at room temperature of tungsten used in halogen heater is around 1/10 of that of operating time. Therefore, at the moment voltage is applied to halogen heater, large rush current flows in. To answer to it, it is necessary to take into consideration for current circuit design such as heightening the impedance of heater circuit. Temperature of sealing portion and life time Sealing portion is made of molybdenum foil and quartz glass. As when temperature of sealing portion rises over 350℃, life time becomes short quickly, so keep temperature of sealing portion below 300℃ in use. ★

Specifications and appearance may be revised for improvement without prior notice.
