Pulsemaster Conditioner:

Unique Features

Pulsemaster Conditioner

The operating principle of the Marx solid-state generator involves the discharge of capacitors in series. The stored energy is discharged into a well-defined load, namely the treatment chamber. This series switching results in a fast rise time of the pulse, which is essential for effective PEF treatment. The rapid rise time is a unique feature of our design.

Furthermore, Pulsemaster has developed innovative switching power supplies using advanced capacitor charging technology, significantly enhancing the reliability of our systems compared to similar products. The advantages include improved operator safety, enhanced modulator reliability, and superior pulse-to-pulse control.

Power Range

Power supply unit

Our robust Marx solid-state typology provides better pulse control and reliability. We offer a range of robust PEF systems covering power ranges up to 100kW per system. The compact, modular design of these systems facilitates easy integration and power upgrades. They are user-friendly and maintainable thanks to modular design with field-replaceable units.

Our engineering experts have extensive experience in designing and building over 70 PEF systems since 2009 for various applications in the food industry. Our pulse generators are proven in food industry and research applications.

Marx Solid-State Typology Pulse Generators


Our Marx solid-state, high voltage pulsed power systems are key for commercial PEF applications. This technology scales from pilot-scale batch units for research to large-scale food processing systems, as evidenced by over 70 systems installed globally since 2009.

Highest Quality Engineering

High Quality Pef Engineering

All PEF systems used in the industry for French fries and crisps, built according to Marx solid-state typology, are derived from Pulsemaster’s team of German engineering experts. Our designs meet regional installation and control system requirements and adhere to certification standards. Each system is built with high-quality German and Dutch engineering for continuous operation.


The pulse generator unit can be installed up to 20 meters away from the treatment tank unit with the transport belt and treatment chamber. This setup allows the pulse generator unit to be placed outside the production hall in a climate-controlled corridor, with the treatment tank unit and treatment chamber inside the production hall.

Robust, Modular & Hygienic Design

All our systems are robust, featuring proven solid-state components for the pulse generators and a design approved by UL and CE. The input power options are versatile. Our modular design incorporates field-replaceable units, facilitating power upgrades. For instance, you can upgrade your existing 50kW system to 100kW. If desired, we can adapt and customize our systems to meet your specific requirements.

PEF Systems

for Science and Research

Pulsemaster manufactures a variety of systems specifically designed for science and research organizations, tailored to meet their unique research needs. Under the brand name Solidus, we produce PEF pilot-scale batch systems that cater to our customers’ research requirements. The Pulsemaster Solidus PEF pilot-scale batch unit is capable of treating both solids and liquids for research purposes.

We offer the versatile Solidus pilot-scale batch unit for either purchase or trial rental. It utilizes a cell disintegration method based on pulsed electric fields, a non-thermal cell membrane permeabilization treatment that enhances process optimization in the food industry. The Solidus PEF batch system enables the assessment of PEF’s impact on plant cell viability in intact solid plant tissues or whole organs, such as potatoes, sugar beets, and carrots. Moreover, the application of the Solidus batch unit extends beyond solid fruits, plants, and vegetables. It can also treat intact animal tissues, such as pieces of meat and fish, to optimize curing time, drying, marination, and tumbling processes.


The design of these custom-made pulsed electric field systems is both compact and modular, facilitating easy integration and power upgrades. The science systems are user-friendly and also simple to service and maintain, thanks to their modular design featuring field-replaceable units. A sufficiently large PEF chamber is included to accommodate large solids, such as potato tubers, and its size does not limit the range of electric field strengths that can be utilized. The PEF treatment chamber is fully encapsulated, and the electrode system is properly grounded. In the engineering of the Solidus PEF pilot-scale batch unit, off-the-shelf components and standardized parts are utilized whenever possible. The electric field strength is adjustable via the output voltage, and the specific energy is calculated based on the number of pulses applied.
