SAIREM

What SAIREM does

SAIREM SAS is a privately held French industrial equipment manufacturer founded in 1978 and headquartered in Décines-Charpieu near Lyon, France, with a wholly-owned US subsidiary (Sairem Corp) near Atlanta, Georgia. The company specializes in industrial microwave and radio frequency (RF) thermal processing technology, and is one of the few operators globally mastering both microwave frequencies (915 MHz and 2.45 GHz) and RF technology (27.12 MHz and a wider 1–300 MHz range). With over 100 employees and more than 5,000 installed machines operating across 70 countries, SAIREM serves enterprise customers in food processing, advanced industrial materials, laboratories, and plasma-based semiconductor-adjacent applications.

The product portfolio is organized across three ranges. The Food range (NutriTemp tempering/defrosting, NutriPure pasteurization, NutriDryer drying, NutriXtract extraction) addresses processors of meat, seafood, fruits, vegetables, prepared meals, pet food, and spices, with documented outcomes such as reducing defrost cycles from 24–48 hours to under 10 minutes. The Industrial range (InnoThermo heating, InnoXtract extraction for cosmetics/pharmaceuticals, InnoDryer drying) targets manufacturers of silica aerogel, ceramics, polyurethane foam, and polyamide powder. The Laboratory range (MicroChem, LaboTherm, LaboBox, LaboPyro) supports research applications. SAIREM also produces generators (EvoMag 915 MHz magnetron, GMP 2.45 GHz magnetron, EvoMicro 2.45 GHz solid-state) and plasma sources (PlasmaSpin vortex, PlasmaThin surface, PlasmaVac low-pressure, plus the Aura-Wave ECR and Hi-Wave collisional self-matching sources used with solid-state generators for PE-ALD and other semiconductor-relevant processes). The technology architecture rests on volumetric heating — inducing dipole rotation to achieve rapid, uniform temperature rise with minimal energy loss — supported by 12 active patents and ISO 9001 certification held since 2014.

SAIREM generates revenue through a mix of one-time industrial equipment sales, equipment rental for on-site piloting, and recurring professional services covering simulation, feasibility studies, test-center commissions, installation, operator training, remote diagnostics, and after-sales support. The go-to-market is direct enterprise field sales augmented by a global network of sales representatives and technical partners, with test centers in France and the USA acting as de-risking assets for customer evaluation. Customer concentration is dispersed across food processors (Czech, Finnish, UK), date cultivators in Tunisia, an insect-proteins processor, a waste/biomethane operator, a French aerogel manufacturer, and a vapor-deposition equipment designer. The company is leadership-led by CEO David Vennin and CTO Jean-Marie Jacomino and is privately held under SAIREM SAS with no disclosed institutional investor or funding history.

Core offering

SAIREM designs and manufactures industrial microwave (2.45 GHz, 915 MHz) and radio frequency (27.12 MHz, 1-300 MHz) equipment for thermal processing applications, including food tempering/defrosting, pasteurization, drying, extraction, and material heating systems. The company also produces magnetron and solid-state generators as standalone products, and develops microwave plasma sources (vortex, surface, low-pressure ECR and collisional configurations) for semiconductor, deposition, and surface treatment processes. Equipment is custom-built to industrial customer specifications and supported by simulation, testing, installation, training, and after-sales services.

Product overview

SAIREM offers a comprehensive portfolio of industrial microwave and radio frequency equipment organized into three product lines: Food range (NutriTemp, NutriPure, NutriDryer, NutriXtract), Industrial range (InnoThermo, InnoXtract, InnoDryer), and Laboratory range (MicroChem, LaboTherm, LaboBox, LaboPyro). The portfolio also includes industrial generators (EvoMag at 915 MHz, GMP at 2.45 GHz magnetron-based, and EvoMicro solid-state at 2.45 GHz) and plasma sources and systems (PlasmaSpin vortex source, PlasmaThin surface source, PlasmaVac low-pressure source, Aura-Wave ECR source, Hi-Wave collisional source). SAIREM also provides accessories and spare parts. The company is one of the few firms mastering both microwave and radio frequency technologies, providing volumetric heating solutions for tempering, pasteurization, drying, extraction, heating, decontamination, and plasma processes across food, industrial, laboratory, and plasma application segments.
