The Air-Heater - Typ LE-6565/2 |
|
Area of application:
Air heaters are usually used in the industrie range for the up-sprayed by hot glue.
Example:
Manufacturers of diapers and similar products use such air heaters, to the up-sprayed hot glue.
The splicing tape on a diaper is thus realized.
At present these air heaters are
available with three power ranges:
• 945 Watt
• 1050 Watt
• 1200 Watt
The voltage is designed according
to your specifications.
To avoid damage, please observe
the following instructions.
|
|
a) Heating
When ordering please note your local voltage. Excess-voltage can shorten the life of the heating elements.
The ratio of voltage and output is shown below:

We recommend that orders are placed for air heaters with your local rated voltage;
the appliances will then work for years without damage to the heating elements.
b) Control
The air heaters are fitted with two temperature feelers (Pt100).
1. For limiting; this protects the heating core from overheating
2. For control; this controls the thermostat which controls the temperature in the heating unit outlet
It must be noted that because of the tension releas in the air at the point of application, the temperature difference between the air outlets and the point of application is greater, the greater the difference in pressure between these two points.
In addition there is the temperature loss through radiation from the air pipes between the air heater and the point of application. For this reason the thermostat must always be set higher by the amount of this temperature loss.
Never attempt to,
increase the temperature by switching off the feeler for limiting the temperature.
By doing this you risk destroying the heating core.
However, you can switch off the feeler for controlling temperature and carry out temperature control using the feeler for temperature limiting.
Maximum control setting: 350oC.
