The two small models for each temperature are tabletop types, while the large model is a floor-standing type. These can be customized to suit the customer's needs. For example, a catalytic afterburner can be attached for the degreasing application of binders.

The RHF series is a chamber furnace that uses silicon carbide heaters, available in four different chamber volumes and three maximum operating temperature combinations of 1400°C, 1500°C, and 1600°C (a total of 12 models). It features a robust construction, high-performance heating elements that enable rapid heating (reaching 1400°C in under 40 minutes), and long service life.

The CWF series is a tabletop type research general-purpose chamber furnace. It can reach a maximum temperature of 1300°C and is available in five different sizes. In the CWF-B, air flows in through the intake port located on the door, and the chimney quickly exhausts waste gases, promoting the incineration of samples. The CWF-BAL is equipped with a built-in scale, making it ideal for thermal gravimetric analysis (TGA) and loss on ignition (LOI) tests, where monitoring weight changes during heating is necessary. These are essential for quantifying organic components in cement, lime, calcined bauxite, and refractories. For ashing samples that are primarily composed of organic materials, the AAF-BAL is recommended.

The main body of the TS furnace is divided into two parts and is secured with hinges at the rear. A gas damper at the end provides smooth opening and closing operations. By allowing the furnace to be split, it becomes easier to equip it with an end flange that makes insertion into undivided furnaces difficult when using containers such as reactors, and it also simplifies the replacement of working tubes. The TS series is designed with flexibility in mind. By using slide-in accessory working tubes and adapters, a single furnace can accommodate tubes of various diameters, and the working tube itself can be easily replaced to meet the physical or chemical requirements of the process. An optional working tube package allows users to use the TS for heat treatment under vacuum or modified atmospheres.

The FST (1 Zone) and FZS (3 Zone) are split tube furnaces that can operate at temperatures up to 1300°C and can be used both horizontally and vertically. The split heating modules make it easy to load working tubes and reaction vessels with fixed end flanges. The separable structure also allows for increased cooling rates of samples. Cooling grooves are incorporated into the housing to promote convective cooling of the outer casing. The upper half of the furnace body is equipped with a handle, and a one-touch clamp allows for safe locking and unlocking. The furnace body is made of ceramic fiber modules, and high-quality APM wire heating elements are embedded in insulation held by ceramic ridges. When the furnace body is opened, a safety switch is activated, cutting off power to the heating elements, ensuring the safety of the operator.

The split-type heating module makes it easy to mount the working tube and the reaction vessel with a fixed end flange. Due to its separable structure, it can also enhance the cooling rate of the samples. The control thermocouple is mounted in the center of the heating area. Cooling grooves are incorporated into the housing to promote convective cooling of the external casing. The split furnace body consists of high-grade insulation plates and vertically installed molybdenum disilicide heating elements. When the furnace body is opened, a safety switch activates, cutting off the power to the heating elements, ensuring the safety of the operator. To allow for installation on self-owned equipment, it is standard without a stand. It can be made self-supporting with an optional L-shaped stand.

High-grade insulation made of fiber plates has a low thermal conductivity, achieving reduced energy consumption and improved heating rates. The insulation material and the heating element made of molybdenum disilicide are built into a rectangular housing. The heating element is installed vertically and is easy to replace. When oxygen is present at high temperatures, molybdenum disilicide forms a layer of oxide, protecting the heating element from further thermal and chemical corrosion. The HTRV series, equipped with a wide range of accessories, provides a perfect system solution for advanced heat treatment at high temperatures. It is designed as standard without a stand for installation on your own equipment. An optional L-shaped stand is available for independent use.

High-quality insulation materials with low thermal conductivity enable low energy consumption and rapid heating. The insulation material and molybdenum disilicide (MoSi2) heater element are housed in a rectangular casing. The heater element is suspended vertically, making it easy to replace. At high temperatures and in the presence of oxygen, MoSi2 forms an oxide layer (SiO2) that protects the heater element from thermal and chemical corrosion. The 3-zone tube furnace (HTRH-3) achieves higher uniformity compared to single-zone products. These models are equipped with dedicated thermocouples and temperature controllers for each heating zone, making them particularly convenient for preheating gases necessary for reactions within the system. The HTRH does not come with a working tube built-in. The working tube can be selected as an additional accessory. The length of the working tube varies depending on the application and whether a modified atmosphere or vacuum is used.

The F series has a wide range of applications and is equipped with a rich variety of accessories. It features a high-quality 5mm APM wire heating element embedded in insulation, held in place by a ceramic ridge. The low heat capacity insulation made of ceramic fiber enables reduced energy consumption and improved heating rates. The control thermocouple is of high-grade type S. Additionally, when precise temperature control and uniformity are required, the heating area can be subdivided into up to eight zones.

The new TF tube furnace series from Carbolite Gero incorporates high-quality heating elements and innovative insulation design, achieving the best performance and high versatility while keeping both the housing temperature and power consumption low. The TF series is designed with flexibility in mind. By using slide-in accessory work tubes and tube adapters, a single furnace can accommodate tubes of various diameters, and the work tube itself can be easily replaced to meet the physical or chemical requirements of the process. With the optional work tube package, users can utilize the TF for heat treatment under vacuum or modified atmospheres.
