Microwave Disinfection and Heat Treatment Chamber

Modern thermal disinfestation technologies make it possible to effectively eliminate insects, larvae, and mites without the use of chemicals. One of the most advanced solutions is the microwave (MW) chamber, which uses electromagnetic energy to evenly heat materials and products.

This type of chamber is used in the woodworking, agricultural, food, and even logistics industries, where complete pest elimination is required while preserving the structure and properties of the material.

It is an innovative, high-tech solution for destroying wood-boring insects and parasites that damage furniture, antiques, and building materials. Wood allows the microwave field to pass through it, and the microwaves act directly on the insects.

The technology is based on the generation of high-frequency electromagnetic waves that penetrate deep into the treated material. Unlike traditional heating, where heat is transferred from the outside, microwave radiation heats the material from within by causing water and protein molecules to oscillate. This destroys insects at all stages of development — including eggs and pupae.

One of the main applications of microwave chambers is combating wood-boring beetles, woodworms, and house fungi in timber. Microwave radiation effectively kills larvae and eggs located deep within the pores of the wood — areas where chemical insecticides cannot reach. This treatment is used for furniture and antiques, beams, logs, joists, parquet boards (even in packaging), musical instruments, decorative elements, sculptures, as well as museum and church artifacts.

Wooden objects such as dressers, cabinets, and nightstands often contain metal parts or inserts. It is worth noting that metal does not affect the process, and there is no need to remove it. The microwave chamber allows valuable items to be restored without damaging the surface or changing the color of the wood.

The method is fully approved by European standards DIN EN 113-1:2021, DIN EN 113-2:2021, as a safe way to protect wood from biological damage.

A separate area of application is the fight against bed bugs in mattresses — especially in the hotel industry.
Microwave treatment allows safe and effective disinfestation without the use of chemicals, preserving the structure of the material and minimizing ecological risks to zero.

Bed bugs are among the most difficult household pests to eliminate. Their eggs and larvae are resistant to most chemical treatments, and those hidden in cracks or mattresses often survive aerosol applications.
Microwave disinfestation solves this problem completely: the entire mass of the mattress or upholstered furniture is heated to 70–80 °C, which guarantees the destruction of bugs, larvae, and eggs — without damaging the fabric or filler.

The process is absolutely safe, requires no ventilation, and can be performed inside a microwave chamber — ideal for hotels, hostels, hospitals, nursing homes, and sanatoriums.

Microwave chambers are also used in the food industry for the thermal disinfestation of raw or processed bulk products such as:

• tea and herbal blends,
• grain, nuts, cereals,
• dried fruits, spices.

During microwave treatment, all types of insects (beetles, moths, mites) and their larvae are destroyed.

The main advantage is sterilization without loss of aroma or taste.
Microwaves do not damage the structure of the product and do not require preservatives.
This extends shelf life and improves sanitary conditions without the use of toxic gases or chemical fumigants.

Beekeepers often face problems such as wax moths and the Varroa mite.
Conventional thermal or chemical disinfection is not always safe for bees or hives and can damage wax and wood.

Microwave sterilization of hives and frames ensures the elimination of pathogens without the use of aggressive substances. When heated to 70–90 °C, all stages of wax moths and disease pathogens are destroyed, while the structure of wax, propolis, and wood remains intact. The method is environmentally safe, suitable for reuse of beekeeping equipment, and helps maintain sanitary conditions in the apiary.

According to the international ISPM 15 standard, export wooden packaging and pallets must undergo heat treatment to eliminate pests. In a microwave chamber, this process occurs quickly and evenly.

The microwave chamber is also indispensable for the conservation of museum artifacts, paintings, manuscripts, and books infested with insects. The radiation does not damage paper or paint, while completely eliminating pests. The process is harmless to personnel and requires no chemical isolation of the area.
