MISTRAL / MISTRAL SYSTEM: 24/7 under control.Sometimes there is no space for a separate blower. There are many reasons for integrating blowers and air heaters

in a compact device – a hot air blower. With its brushless motor the MISTRAL / MISTRAL SYSTEM is intended for

long-term, continuous use in heavy industrial environments. The demand for controllable and adjustable industrial

hot air systems is constantly growing. With the MISTRAL SYSTEM the heating performance can precisely be controlled

via the normal industry standard control signals.

Air heater

LHS 15

The tiny air heater provides hot air up to 1202 °F. All prominent features of Leister air heaters are also offered with this

tiny heater: long-life heating element, reliable protection systems, standard interfaces. Simply summarizing - the same

Leister quality as usual. This makes it a perfect tool for applications in Semiconductor, Electronics, Automotive and

other industries.

Combination possibilities- Leister air heater at maximum heat power and without nozzle with Leister blower at

50 Hz, 4.9 ft hose length and unimpeded air outflow.- Hot air temperature 0.12 in after air outlet, measured at the hottest point.- Air flow at 32 F°, 14.7 psi compliant with DIN 1343.

Frequency converters: More power for your blower.

Spectrum of Leister’sAIR RADIATION HEATER

Heating is achieved by the absorption (A) of the radiationin the material.

A certain percentage of the complete intensity of theradiation can be transmitted (T) and reflected (R) depen-ding on material properties.

100% = A + R + T

Infrared (IR) light is electromagnetic radiation with a wavelength between 0.7 and 300 micrometres. IR wavelengths

are longer than that of visible light, but shorter than radiation of microwaves. Bright sunlight at zenith provides an

irradiance of just over 1 Kilowatt per square meter at sea level. Of this energy, 527 Watt is infrared radiation, 445 Watt

is visible light, and 32 Watt is ultraviolet radiation. Infrared radiation can be used to head up material.

Infrared radiation (IR): Invisible but helpful.

Features

• IR radiation is effectively absorbed by most materials• Designed for continous operation in industrial environments• The small heater footprint allows integration into small spaces

in machines• Standalone operation without air supply is possible• Can be used to evacuate humid air in drying processes by

reversing the airflow through the AIR RADIATION HEATER• Modular design allows multiple AIR RADIATION HEATERS

to be used to cover large areas • Ideal in combination with either hot air or ambient air

and radiation

By combining heat absorption and heat convection, the new AIR RADIATION HEATER from Leister takes large-area

drying and targeted heat input applications to next level. On request, the infrared heater comes in combination with

hot air, supplied by a Leister air heater. The AIR RADIATION HEATER is designed to maximize your heating process

in terms of energy efficiency, resulting in higher productivity.

A nifty combination: The AIR RADIATION HEATER from Leister.

Typical applications

• Platic welding • Remelting• Coating • Activation of surfaces• Hardening • Joining• Softening • Triggering chemical reactions• Selective desiccation • Soldering

Whereas hot air blowers and middle wave infrared systems achieve a powerdensity of 10-20 W/cm2, short wave IR or halogen systems achieve a powerdensity of 100-300 W/cm2. If the application requires a higher power density, a laser is used. A laser system, however, achieves a power density of 100’000W/cm2, thanks to its high focusability. With laser, process heat is applied at highprecision and can be applied locally.

The techniques also differ with regards to heat input. With hot air, the processheat is applied on the surface. Infrared or laser radiation apply the heat on onespecific layer of the surface or within the material, depending on the wave lengthand absorption properties. In this case it is important that the radiation is notheavily reflected by the material.

Compared to infrared radiators, laser provides more power per area. Furthermore,laser can be used for delicate patterns. This solution is especially interestingwhere process heat is used on limited areas of the surface layer. The finepatterning of the laser radiation can be realised by shading the beam with a mask.

Hot air and infrared radiation are frequently used for industrial process heat. If high power density or fine patterns

are required, these techniques are reaching their limits. It is for these applications that laser may be an option.

Laser for Process Heat: High power density applied with high precision.

Most industrial processes require energy. Bringing energy into processes requires power and time. In the following

there are some simple basic calculations that can give first estimations on required heating power. Additional

application test are always recommended and supported by Leister.

Useful formulas: Help yourself.

The following formula are meant as rules of thumb. They can be employed as first estimations to plan equipment.

The calculated values serve as approximate values. Losses are not considered.

To increase pressure the blowers have to be combined in series.

To increase air flow the blowers have to be combined parallel. The

characteristic curve of the combination is given by addition of the

To avoid backpressure the crosssectional area of the outlet has to

be at least of double size compared to a single blower.

The example on the right shows the characteristic curves of a
