Catalog of industrial drying ovens of the SNOL series with operating temperatures up to +300°C or +500°C from the manufacturer TULA-TERM. In the product card, you will find current prices, technical specifications, selection criteria, and delivery options across Russia. ## Purpose and Application Industrial drying ovens (low-temperature furnaces) are stationary equipment with forced convection, designed for drying, aging, tempering, and other heat treatment of materials in an air environment at temperatures up to +500 °C*. This is basic equipment for thermal sections in industry and science. TULA-TERM has over fifteen years of experience in the design and production of low-temperature furnaces and drying ovens. We know all the specifics of technological processes, so our equipment ensures uniform heat distribution throughout the chamber volume and is equipped with a convenient control system. Our models are versatile equipment that, depending on the application, can be called a "drying oven" or a "low-temperature furnace." In some manuals, the operating temperature range of our equipment (up to 500 °C)* is referred to as "medium-temperature," and accordingly, such furnaces (ovens) may also be called "medium-temperature furnaces." *Maximum temperature +500°C is available for models with the /5 index. Models with the /3 index operate up to +300°C.* Main areas of application by type of technological process: - **Convection drying**. A heat and mass transfer process for removing liquid from solid materials or mixtures by evaporation in a stream of heated air (up to 500 °C). In this context, the equipment is a drying oven. - **Artificial aging**. Heating to accelerate the precipitation of dispersed phases from a supersaturated solid solution, which increases hardness and strength (e.g., aging of duralumin). In this case, it is a low-temperature furnace. - **Quenching, homogenization**. The reverse process of aging. In this case, it is a low-temperature furnace. Technically, it is the same design. Our catalog also features [specialized models of chamber furnaces for intensive use](https://tula-term.ru/oborudovanie/kamernye-nizkotemperaturnye-elektropechi-soprotivleniya-sno "specialized models of chamber furnaces for intensive use"). ## Key Criteria for Selecting an Industrial Drying Oven To ensure a high-quality and fast result, the following conditions are important: - Ratio of chamber volume to load. The working chamber volume should significantly exceed the load volume. The recommended minimum gap for air circulation is 300 mm. We advise against saving on volume and recommend buying an industrial drying oven with a larger working space: the more free space, the more uniform and faster the process. - Matching power to load mass. Power is selected based on the mass, material properties, and required productivity. Our engineers will perform an accurate thermal calculation. - Presence of a forced convection system (fan). Ensures uniform circulation of hot air and prevents the formation of "cold zones." - Chamber material. For most processes, especially those involving moisture or aggressive environments, a chamber made of AISI 304 stainless steel is recommended. For many drying processes not involving corrosive environments (wood, textiles, some building materials), a carbon steel chamber with coating (И1) is sufficient and significantly cheaper. - Temperature control accuracy. A modern programmable controller allows setting and maintaining the required modes. - Control system. A user-friendly interface and the ability to integrate into the overall technological process increase operational efficiency. Answers to other frequently asked questions about operation and configuration are provided in the [special support section](https://tula-term.ru/servis-i-podderzhka/chasto-zadavaemye-voprosy "special support section"). ## Popular Models of SNOL Drying Ovens We offer a wide range of industrial drying ovens with a fan (forced convection) under the SNOL brand. The equipment is manufactured in accordance with TU 3443.001-92992216-2014, GOST 51837-2001, and other regulatory documents.

We are also ready to develop a custom solution for your technical specifications. If necessary, we provide an extended warranty on the equipment. ## Design and Configuration The oven is a rectangular metal housing with a chamber made of AISI 304 stainless steel (or other material per the customer's technical specifications). Standard volume ranges from 200 to 4000 liters. **Design includes:** - Heating unit (tubular electric heater) in a steel sheath. Designed for quick replacement without special tools. - Forced convection system (fan) for uniform heating throughout the volume. - Viewing window with illumination for visual process control (optional). - Input for a control thermocouple (ТХА). Sensor replacement does not require disassembling the housing. - Independent emergency thermocouple for overheat protection. - Optional: humidity sensor, programmable controller, explosion-proof design (Вз). **Standard configuration:** - Drying oven — 1 pc. - Operational documentation — 1 set. - Spare parts kit (according to the list) — optional. - RS485/USB adapter (for models with a digital interface) — optional. Standard color scheme: housing — RAL-7032, doors — RAL-5010. Color changes per the RAL catalog are available at an additional cost. ## How to Order an Industrial Drying Oven?
