Total Engineering of Light and Heatby 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)” thatrealizes these targets.
Miyakawa has been working for over 15 years on theresearch and development of the “Halogen Heater” to turnit 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 isthat the radiated energy from directly heated metal
at high temperature is utilized without the generationof useless energy.

Halogen heaters are designed for long life – morethan 5,000 hours at an average rate except certain
types - due to halogen cycle effects (the function thatreins 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 iseasy and economical.

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

6> Downsizing
Big feature of Halogen heater is light weight andpossible downsizing. In narrow places or places
where other heat sources are hard to bring in, theinstallation is possible. And handling is very easy,
because structure and function are simple.

OptionBlack coating type (far-infrared ray heater)
Coated by special ceramic coating on the surface ofheating element, this type converts almost 100% ofvisible radiation output and 70〜80% of near andmiddle infrared output to far-infrared ray. Comparedwith the amount of far-infrared ray generated byregular 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 portionof normal QIR heater, gas and fine particles aredischarged when used in vacuum, causing certaintroubles.

Vacuumspecification

QIRheaterisconstructed without using these materials. As aresult, the heater can be used in vacuum without fail.
However, as service conditions vary depending upondegree of vacuum and temperature of QIR heater’s
sealed part, if the heater is used under specificcondition, 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 beomitted, then downsizing and space-cutting ofsystem can berealized.

Vertical type

Allowable

using

angleof

Halogenheateris±4°against horizontal plane. If used over this limit,
extreme short-life or other faults occur. This vertical
type is recommended for use over allowable angle. If
there are any unclear points with regard to use
conditions, please contact with the Manufacturer.

The Manufacturer will comply with the customers’ demands with regard to dimensions and ratings etc
of all products regardless the quantity..

Comparison of energy distribution and efficiency, etc.
Energy distribution of the infrared rays
Electromagnetic waveｓ with wavelength of 0.8µm to 1mm

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 rayNear infrared ray (i.e. halogen heater) is the highest in energy
efficiency and its big characteristic is that its energy isconcentrated 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.

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

Otherwise the appliance may overheat or be transformed, causing extreme shortlife.
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 theheater becomes tainted, wipe it out cleanly with alcohol etc. and use it (When handlinghalogen 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, rustor 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 isnecessary to take into consideration for current circuit design such as heightening the impedance of heatercircuit.
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.
