Industrial microwave generators
Microwave generators are used to create microwave energy. This energy is then used in many ways, in many sectors and for different purposes. Most of the time, microwaves are used in thermal processes for their ability to heat. Our microwave generators are available at all powers and their characteristics can be adapted to your needs.
What is a microwave generator?
A microwave generator is a sophisticated, mostly electronic, piece of equipment designed to generate and send microwave energy. The microwave energy is mainly used to heat products or generate plasma, and is very useful for many applications in various sectors such as industry, food processing, surface treatment, science…
Microwave generators are available as standalone solutions or can be integrated into complete microwave systems as required.
How does a microwave generator work?
Microwaves are always created by a magnetron or by a solid-state microwave generator.
Microwave radiations are used in heating and drying processes thanks to the dielectric loss properties of materials. The quick polarity reversal of the electromagnetic field creates vibration and rotation of the polarised molecules inside the material. This phenomenon is the origin of the heat generated.
Why use a microwave generator?
Microwave generators can be a perfect solution to improve thermal processes in different sectors. They also represent an energy source than can be used for scientific and industrial applications.
Microwave generators are ideal to improve heating and drying processes. For the food industry, they allow food products to be quickly tempered or defrosted; but they can also be used in the industrial sector to heat or dry different kinds of materials (ceramics, wood, powder, textiles…) and for chemical processes such as vulcanization or polymerization.
Microwave energy also has advantages sought in the scientific field, especially to generate plasma. In addition, SAIREM microwave generators can be used for the production of PECVD synthetic diamonds.
What is solid-state microwave technology?
Solid-state microwave power generators (SSPG) are the next revolution in the microwave technology field. Although they are still limited to a few kW in power, they offer many advantages compared to previous magnetron technology, such as delivering a stable and narrow microwave signal at 915 MHz and 2,45 GHz, and offering an almost unlimited lifespan.
SAIREM is at the forefront of this technology with several solid-state microwave generators already available on the market.
Are microwave generators safe?
Microwaves are a form of electromagnetic radiation, which may suggest they are dangerous. But, as they are non-ionizing radiations, their effect does not last over time. Furthermore, SAIREM systems, and all microwave systems in general, are closed and fitted with sensors to prevent microwave leakage.
For the most sensitive areas of application such as laboratory research, SAIREM provides additional security by means of a wall-mounted alarm which will detect any microwave leakage in the immediate vicinity of a microwave system and sound an alert should any occur.
Why choose a SAIREM microwave generator?
Our microwave generators are designed to operate independently or remotely controlled, with a minimal footprint and good signal stability. They can deliver anything from hundreds of watts to up to hundreds of kW with significantly reduced power loss. SAIREM microwave generators work at all authorized ISM frequencies, although most of them are designed at 915 MHz and 2450 MHz.
The reliability of the microwave generators offered by SAIREM, both as standalone and integrated units, is recognized and appreciated by many OEMs and research laboratories worldwide. Their modern design allows them to be easily integrated and used in a wide variety of environments.Contact us
The history of microwaves
Microwaves, which are part of the electromagnetic spectrum, were discovered by James Clerk Maxwell in 1864, and were first shown to exist in 1888 by German physicist Heinrich Hertz. They have since been used in a number of critical applications, first in radars, then for heating applications, and finally as a foundation of modern wireless telecommunications.
