Hi-Heater heating instantaneouslyMiyakawa is a proposal-oriented business organization where“light and heat” are handled from engineering point of view.
Miyakawa provides not only manufacture and sale of Heaters but also make proposals on developmentof facility relevant to “light and heat” that will fulfill customers’ satisfaction.

Various conditions

With the combination of compact body and a variety of blowing nozzle configuration, the heater meets
customer’s various needs such as local heating and wide area heating.
Technical strength that Miyakawa is proud of【3 points】
1. Long life thanks to improvement of durability performances
Coil-stopper mechanism is our own technology that improves durability performances. The technology can suppresschange of coil shape that causes open heater.
2. Sensor to prevent extreme temperature rise is fixed to heater body
It prevents from overdriving of heater, when temperature-controlling thermocouple fails, heater opens ortemperature regulator is out of order.
3. Wide variety of hot air blowing nozzle can be designed and manufactured
There are 2 kinds of nozzles to manipulate hot air, that is metal processing and glass processing. If a desired nozzle
configuration is designated, the manufacturer will design and manufacture it.

Various kinds of the heaters
Other than the standard Hi-Heater, we have ①Micro Hi-Heater, ②N2 Hi-Heater (exclusive use for nitrogen),③Burring Hi-Heater (exclusive for burring) and ④Slit nozzle.

There are various types of controller from cheap edition to the all-in-one-type in which temperature, air pressure
and air flow can be controlled. The manufacturer designs and manufactures controllers that meet the customers’
needs. The details can be downloaded from the manufacturer’s home page. Information materials from ① to ③
below are available for the customers’ review.

● Observe such work sequence strictly, that is, flowing air
prior to putting electrical source and shutting it about
60 seconds after turning off the electric source.

● Kind of gas
The gas which can be use for this basically “air”.
Use gas which does not contain oil-mist moisture.
When using nitrogen, consult with the manufacture.

● In case of using commercially available temperature
controller, actual temperature may not be stable.
It is recommended Miyakawa’s exclusive controller to be used.

● Pressure and flow
Air pressure that suits Miyakawa’s Hi-Heater is therange of 0.1Mpa to 0.3Mpa. With regard to flow,
please refer to “Relation between hot air discharge
rate and temperature” graph.

● Heater life could be extremely short if it is fixed to movablepart such air-cylinder. Check once with the manufacturer.
● If calm condition (no wind) continues for long period or highloading voltage is applied to the heater at low flow
(0～10L/min) atmosphere, blow opening of stainless tube
begins to become red. If this state continues for 1～2minutes,
the heater breaks (opens).
Be careful about the stainless tube not to become red heat.

● Rise time of Hi-Heater
It reaches to preset temperature in 30～60secs.

Consult with the following 3 patterns with regard to thecriterion whether the heater is used in good condition.
In case of the standard output type, there are 4 openings
on the stainless tube.
Color shade seen through these holes are the criterion.
Hot air of 600～700℃ is flowing.
(goes red to the 3hd hole from rightside)
Color of stainless tube is normal.
*As hot air temperature becomes high,tube turns red from the right side of far

Hot air at hotter than 900℃ is flowing.
Head of stainless tube begins to glow.

●Measurement condition
Voltage:100V Type name of the measured unit: ASH-1AH(100V 350W)
Flow: 15L/min Measuring position: At 2mm for tip of blow opening.

Central part of stainless tube glows.

Background information for selectionof Hi-Heaters (Refer to 3 and 4pages)
Before use of the Hi-Heaters, please
select 5 items on the right.
If you have any questions.
Please contact with the manufacturer.

1) Voltage

2) Output

Select either
One of
100V or 200V

Select between
100W～3KW

5) Temperature sensor
Select from T, T2 and T3 type
T type “Temperature-regulating thermocouple” which is built in nozzle tip
T2 type “T Temperature-regulating thermocouple” and “Overheating-prevention
thermocouple” (This is fixed to heater body and it prevents fromover-driving of heater, when T fails, heater opens or temperature
regulator is out of order.
T3 type Body temperature of heater is monitored by thermostat and overheatingof the body prevented.

3) Nozzle configuration
Select from basic configurations-A, B, C, D, P.
Dimensions are modifiable in case of B, C and D.
In case of standard output type-B: 2mm diametercan be modified to 3mm and 4mm.
In case of standard output type-C:27mm×0.5mm
can be modified freely.

4) Base configuration
Two type of basic
H and F

The manufacture provides with special order items. Please indicate desired nozzle configuration① Quartz nozzle 90°bent② Quartz nozzle 45°bent (slit width:10mm×2mm)③ Quartz nozzle Circle type facing blow
④ Metal nozzle 30°bent (φ2mm)⑤ Metal nozzle 45°bent (φ2mm)⑥ Metal long nozzle⑦ Metal flat nozzle porous hole type
⑧ Metal slit nozzle (0.15mm×100mm) * blows hot air like air curtain.

*Details about metal slit nozzle can be downloaded from the home page.
