Product catalog summary
Construction:
Vacuum ovens are available in four sizes ranging from 20 to 240 liters. The control panel is located on top to minimize space usage. The inner casing is made of thick stainless steel (4 mm) and is reinforced for the 120 and 240-liter models to resist corrosion. The outer casing is made of electro-galvanized steel with a light grey epoxy paint finish. There is no contact between the inner and outer casings to prevent thermal bridging, ensuring low surface temperatures. The optimized thermal insulation consists of 70 mm glass wool, asbestos-free. The door features a thick toughened glass window (8 to 15 mm depending on the model) and a removable silicone gasket for easy cleaning or loading.
Heating:
Heating is provided by stainless steel shielded flat resistors distributed around the stainless steel chamber for optimal temperature uniformity. Solid-state relays ensure contactless and interference-free power supply. Optional heating can be provided by one or more heating shelves (except on XF020).
Pressure Measurement:
Internal pressure is indicated by a needle vacuum gauge ranging from 0 to -1 bar. An optional piezo-electric sensor allows digital pressure display with a resolution of 1 mbar.
Regulation, Control, Safety:
Temperature is measured by a Pt100 probe. The electronic PID controller C3000 displays the set and measured temperatures digitally. An independent adjustable safety thermostat (level 3.1) cuts off heating in case of main regulation system failure, protecting the oven and its contents.
C3000 Controller Details:
The FRANCE-ETUVES C3000 PID controller offers functions such as temperature measurement with a Pt100 Ω probe, set and actual temperature display, delayed start (1 min to 99h59 min), temperature ramp, holding timer (0 to 99h59 min), repeat loop, end-of-cycle buzzer, and overtemperature alarm.
Equipment:
Multiple position shelving allows convenient loading/unloading. Vacuum ovens come with a perforated stainless steel tray and two supports.
Performance:
Temperature range is from 20°C above ambient to 200°C max (300°C optional). The electronic regulator displays with 0.1°C precision, and regulation stability is better than ± 0.2°C. The Pt100 probe inside the chamber ensures temperature measurement close to the treated product's temperature.
Technical Data:
The XF line includes models XF020, XF050, XF120, and XF240, with varying internal volumes, dimensions, and weights. The ovens operate on a 50 Hz 230 Volts single-phase electrical supply, with heating power ranging from 800 to 3015 Watts at 200°C, and up to 4320 Watts with the 300°C extension option.
Options and Accessories:
Options include maximum temperature extension to 300°C, piezo-electric vacuum gauge, additional safety thermostat, weekly automation with a digital timer, and more. Accessories include extra shelves and a pump unit.

FRANCE ETUVES 2014-05 www.france-etuves.com Etuves à vide V acuum Ovens Les étuves à vide France Etuves sont faciles d’emploi et rassemblent des équipements fonctionnels et pratiques. Elles conviennent pour les applications de séchage doux de produits sensibles, de traitements thermiques de matériaux risquant de s’oxyder, de séchage rapide de poudres et granulés, aussi bien dans les laboratoires que dans les industries pharmaceutiques, cosmétiques, plastiques, électroniques, chimiques ou agro-alimentaires. France Etuves vacuum ovens are easy to use and have functional and practical equipments. They are suitable for various applications: mild drying of delicate products, thermal treatments of oxydable materials, speed drying of powders and granules, both in the laboratories and pharmaceutical, cosmetic, plastic, electronic, chemical or agri-food industries. PERFORMANCES : - Plage de température : 20°C au dessus de la température ambiante à 200°C maxi (ou 300°C en option). - Précision d’affichage du régulateur électronique 0,1°C. - Stabilité de la régulation meilleure que ± 0,2° C. - Mesure de température : une sonde Pt100 placée à l’intérieur du volume utile, ce qui permet d’afficher une température la plus proche possible de celle du produit traité. PERFORMANCES: A highly versatile range of compact vacuum ovens. These vacuum ovens enable heat sensitive materials to be dried at low temperature. More stable samples can be dried at higher temperature up to 200°C or 300°C as an option. You can use our vacuum ovens for any laboratory or industrial application. Designed to operate from room temperature +20°C up to 200°C (300°C in option). Final vacuum of 10-2 mBar, depending on the vacuum pump used. Temperature time fluctuation: less than ± 0,2°C. - Les étuves à vide existent en 4 volumes de 20 litres à 240 litres. - Leur tableau de commande est placé sur le dessus pour un encombrement minimal. - Le caisson intérieur est en inox de forte épaisseur (4 mm), renforcé pour les modèles de 120 et de 240 litres, particulièrement résistant à la corrosion. - Le caisson extérieur est en tôle électrozinguée revêtue de peinture époxy de couleur gris clair. - Le caisson extérieur est séparé du caisson intérieur inox pour éviter tout pont thermique et garantir des températures superficielles réduites. - L’isolation thermique optimisée est constituée de 70 mm de laine de verre et excluant tout produit contenant de l’amiante. - La porte est constituée d’un hublot en verre sécurit épais (de 8 mm à 15 mm selon les modèles). - Le joint en silicone est facile à démonter pour nettoyage ou pour chargement. CHAUFFAGE : Le chauffage est assuré par des résistances plates sous blindage inox, réparties autour de la cuve inox pour procurer la meilleure homogénéité de température possible. Des relais statiques assurent la mise sous tension du chauffage sans contact et sans parasite. En option, le chauffage peut être réalisé par un ou plusieurs plateaux chauffants (sauf sur XF020). - Four sizes from 20 to 240 litres. - The inner casing is made of corrosion resistant stainless steel, with rounded corners. - The outer casing is made of sheet steel, finished in a tough stoved epoxy paint (colour light grey). - No contact between inner and outer casing and an optimised insulation minimise heat dissipation. - The walls are insulated with glasswool, low external temperatures and excellent thermal stability. - The door is a thick toughened glass plate. - The silicone rubber gasket provides a good seal between the door and the oven body. - The insulation and the gasket are asbestos-free. - The door is hinged on the right hand side. HEATING QUALITY: The chamber is heated by large area heaters strapped to its outer surface. No-wear switching (solid state relay) is used for activating and deactivating the heating elements.
