Industrial Furnaces and Heat Treatment Plants

Construction and Design Variants

The many years of cross-industry experience of the SCHWING heat treatment experts and the outstanding technical competence and resources of the SCHWING Group enable almost any furnace design or construction method.

The SCHWING systems are controlled by professional open and closed loop control technology (PLC control with process data recording), which is characterized by high operator comfort, individual configurability as well as complete charge and process documentation.

In the customer-specific plant design, the requirements of application-, industry- and country-specific standards, such as DIN EN 1539, AMS 2750 in the aviation industry or CQI-9 in the automotive industry, or the guidelines of the US FDA for pharmaceutical and medical products, are taken into account in particular.

Chamber Furnaces

for batch processes

Chamber Furnaces

Chamber furnaces are characterized by a compact, simple design. For batch operation, the products are fed in and out of the oven chamber through one and the same opening (front loader).

Multi-Chamber Furnaces

for multi-stage processes

Multi-Chamber Furnaces

Multi-chamber furnaces consist of adjacent or successive furnace chambers which, in the case of separable chamber systems, can also be operated at different temperatures.

Deck Furnaces

optional with integrated lifting system

Deck Furnaces

The space-saving deck furnace enable multi-stage heat treatment of products in superimposed process chambers by front-loading per chamber or by means of an integrated lifting/conveying system.

Toploader Furnaces

vertical loading and unloading

Toploader Furnaces

Toploader furnaces are chamber furnaces with a furnace lid that can either be opened sideways (chest furnace), pushed open or lifted for vertical loading and unloading (e.g. by crane). Side loading/unloading is also possible.

Drawer Furnaces

compact for smaller batches

Drawer Furnaces

The products are placed on a pull-out drawer door and, when it closes, are moved into the process chamber. This design is suitable for smaller batches and, in the case of multiple oven chambers, for treatments with different temperatures.

Hood Furnaces

absolutely barrier-free

Hood Furnaces

In a hood furnace, the entire furnace chamber slips over the products like a hood. This chamber furnace design allows 360° access to the products or components.

Bogie Hearth Furnaces

optional with roller systems

Bogie Hearth Furnaces

Large products or complex components are moved into and out of the chamber furnace on a manually or electrically operated trolley with specific holders, supports, racks (bogie hearths) or roller systems for component rotation. Can be loaded by crane or forklift.

Rotary Plate Furnaces

for different dwell times

Rotary Plate Furnaces

The products are placed on a rotary plate in the chamber furnace. The rotary movement ensures uniform product temperature control and, in addition to a first in / first out mode of operation, also enables different product dwell times with targeted loading/unloading.

Continuous Furnaces

including integrated conveyor technology

Continuous Furnaces

In a continuous furnace, a transport system automatically conveys the products through one or more furnace chambers, enabling a discontinuous/continuous flow of products through different temperature zones, for example.

Special Furnaces

Individual developments and functional combinations

Special Furnaces

Individual customer and application-specific requirements are an integral part of our industrial furnace solutions of any design and dimension. The combination of different designs also enables particularly space-saving, multifunctional heat treatment plants.

SCHWING Chamber Furnaces

Our chamber furnaces are industrial furnaces and cooling systems operating with circulating air for batch operation at temperatures up to 600 °C. They are characterized by high energy efficiency as well as a compact and space-saving design. The construction of our chamber furnaces is individually designed according to process requirements, i.e. depending on the type of treatment, temperature profile and component size or geometry, etc.

The desired process temperatures can be generated by any suitable heat source (electricity, gas, oil, steam, thermal oil, etc.). The basic design goal is to use heat sources that are as low in CO2 as possible. All of our chamber furnaces provide maximum uniformity of the circulating air based on the application.

SCHWING Continuous Furnaces

Whether continuous flow production with high quantities or discontinuous series production with several production stages: SCHWING’s industrial furnaces and heat treatment systems operating with circulating air support every manufacturing process with precise, even complex temperature profiles up to 600 °C. Our furnace systems can be operated with almost any heat source, and our goal is to use energy sources that are as low in CO2 as possible.

For the most precise air circulation and temperature accuracy possible, we use in our continuous furnaces

  • direct and indirect air routing, air distribution and nozzle systems
  • production-specific furnace door or feeder systems as well as
  • conveying technology for the respective production process.

Customized special furnaces from SCHWING

Since 1969, SCHWING has been known for the development, construction and operation of individual furnace systems and thermochemical plants: The “Thermal Cleaning” division (SCHWING Technologies), for example, is a globally recognized expert in the construction of thermal cleaning systems for the international plastics and fiber industry. The “Process Technology” division develops and manufactures application-specific gas-solid reactors up to 1100°C for customers in the chemical industry. The “Fluidized Bed Heat Treatment” division focuses on fluidized bed systems for the paint/lacquer, automotive, aviation/aerospace and medical technology sectors, among others.

Based on this profound know-how and experience, the heat treatment specialists at SCHWING Thermal Solutions design any desired circulating air heat treatment system according to the specific application and customer requirements:

Only physics defines our limits.

3P Model for Heat Treatment Plants

The SCHWING Thermal Solutions heat treatment team concentrates special industry experience, specific application competencies and sound technical know-how.

When planning and designing our industrial furnaces and heat treatment plants, the proven “3P Model for Heat Treatment Plants” helps to reliably specify the respective customer requirements from the perspective of the product or application objective, of the thermal process and of the individual installation or integration situation and to implement them in successful heat treatment solutions:
