IMP-VP Vacuum Pressure Impregnation System

IMP-VP Vacuum Pressure Impregnation System is designed to provide a high-quality impregnation process for your wood products.

ISVE wood impregnation plants are designed to maximise penetration of active ingredients in different timber species to use CLASS 4-5. A technology that allows the active and protective ingredients to better penetrate the wood fibres ensuring superior protection against fungus and other pathogens. These plants are built with high quality that guarantee a long-lasting service life.

They consists of an autoclave where the wood is treated. Loading timber into the autoclave is simple and efficient thanks to the unique trolley and door timber mechanism After the first vacuum stage, the impregnating solution is flooded into the autoclave and forced under pressure into the cell structure of the timber. The combination of the initial vacuum and high-pressure stages guarantees a total penetration of the active ingredients.

ISVE IMP-VP system is designed to be easy to use and maintain. It is equipped with a user-friendly interface that allows you to control the impregnation process with ease and it is also designed to be energy-efficient, which helps you save on energy costs.

Don’t miss out on the benefits of our wood impregnating systems.

Staff Ligna 2023

ISVE at LIGNA 2023!

We are excited to have once again taken part in this 2023 edition of LIGNA, the world’s leading trade fair for woodworking technology and the wood industry.

A true international showcase of innovations and the stage for world novelties, this is a great opportunity for companies like ISVE to showcase their wood and recycling products and technologies.

Our company’s focus for this edition is to inform visitors of the changes in our plants aimed increasingly at sustainability.

Come and visit us until Friday 19 May 2023 at stand M22 in hall 025, where our staff will be happy to show you our types of machinery and their particular functioning.





The equipment supplied to the fire-retarding and preservative impregnation plant built by ISVE for a major Swedish customer included a salt mixer.

This system is equipped with various automations for dosing products during both loading and unloading, and can also be interfaced with other machinery, such as conveyor belts and screw conveyors.

This silo designed by ISVE consists of:a 3 cubic metre AISI 304 chamber to receive the salts to be mixed; an horizontal mixing reel an unloading screw; a screw conveyor to transfer salts into the respective mixing tank.

However, this mixing system is also used in other industrial sectors, from chemicals to plastics, but also pharmaceuticals and foodstuffs, with the appropriate modifications and certifications.

The technological evolution of ISVE vacuum dryers continues. After the differentiated temperature control on each individual plate for electric machines (ISVE POWER CONTROL), our company has developed internally with its own resources and technology, the new entirely wireless sensor technology.

The entire range of ISVE dryers will abandon wired sensors and use this technology to control the humidity and temperature of the wood being dried.

The advantages of this choice include:

Easier preparation of the wood pile, which can also be done away from the machine; Number of probes that can be easily implemented by the customer without any particular limitations; Thanks to the specific design of the sensor, moisture control can take place at different points in the pile, either in the centre or on the periphery; Very high reading reliability.

The international installation of BurnBlock vacuum pressure plants with dedicated automation for fire-retarding treatments continues.

The 9-metre long plant has been installed and tested in New Zealand and is ready for production. These machines are characterised by a high performance of automation, capable of certifying the penetration of the impregnating solution with three levels of control, in order to guarantee the correct level of fire-retardant product per cubic metre of wood treated
