CARBOLITE

Carbolite is a manufacturer of laboratory and industrial furnaces, ovens, and incubators, with a history dating back to 1938 in the United Kingdom. The company is known for its thermal processing equipment designed for applications requiring precise temperature control and uniform heating. Carbolite's product portfolio includes box furnaces, tube furnaces, muffle furnaces, and custom-built systems, serving sectors such as materials testing, ceramics, metallurgy, and research laboratories. The furnaces are engineered with features like gravity convection for natural air circulation, which ensures consistent temperature distribution without forced airflow, making them suitable for heat treatment, ashing, sintering, and other processes where sample integrity is critical. Key technical specifications across the range include maximum temperatures from 1,100°C to 1,700°C, chamber capacities from 0.18 to 1.27 cubic feet, and power ratings from 2,400 W to 9,000 W. Temperature stability is typically maintained within ±5°C, and units operate on standard 200–240 V AC supplies. Carbolite furnaces incorporate robust insulation materials and heating elements designed for longevity under repeated thermal cycling. 3G Electric supplies a selection of Carbolite natural gravity convection box furnaces, including models such as the RHF1408-230SN, HTF1710-230SN, ELF1123-230SN, CWF1113-230SN, CWF13036-230SN, CWF1223-230SN, CWF1105-230SN, and CWF1313-230SN. These units are available with datasheets providing detailed dimensional, electrical, and performance data to support specification and integration into existing workflows. 3G Electric offers logistics support for global shipment, ensuring that procurement specialists and plant engineers can source these furnaces with documented compliance to operational requirements.

Frequently asked questions

Common questions about CARBOLITE from 3G Electric.

What temperature ranges are available for Carbolite box furnaces supplied by 3G Electric?

Carbolite box furnaces available through 3G Electric cover maximum temperature ratings from 1,100°C to 1,700°C. For example, models like the ELF1123-230SN and CWF1113-230SN are rated to 1,100°C, while the CWF13036-230SN reaches 1,300°C, and the HTF1710-230SN achieves 1,700°C. This range allows selection based on application requirements such as ashing, heat treatment, or sintering.

What is the typical temperature uniformity specification for Carbolite gravity convection furnaces?

Carbolite natural gravity convection box furnaces are specified with a temperature uniformity of ±5°C across the chamber. This is achieved through natural air circulation without forced fans, which minimizes sample disturbance and is suitable for processes requiring consistent thermal profiles, such as annealing or material testing.

What electrical supply is required for Carbolite furnaces from 3G Electric?

The Carbolite furnaces listed by 3G Electric operate on standard 200–240 V AC single-phase power. Specific models may have voltage requirements within this range; for instance, the RHF1408-230SN accepts 200–240 V AC, while others like the CWF1113-230SN are specified for 240 V AC. Always verify the exact voltage rating on the datasheet for the chosen model.

What chamber capacities are offered in the Carbolite box furnace range?

Carbolite box furnaces available from 3G Electric have chamber capacities ranging from 0.18 cubic feet (e.g., CWF1105-230SN) to 1.27 cubic feet (e.g., CWF13036-230SN). Intermediate sizes include 0.28, 0.35, 0.46, and 0.81 cubic feet, providing options for small-scale laboratory work to larger batch processing.

How does natural gravity convection work in Carbolite furnaces, and what are its advantages?

Natural gravity convection relies on the principle that hot air rises and cool air sinks, creating a natural circulation pattern within the furnace chamber. This eliminates the need for mechanical fans, reducing noise and potential contamination. It is ideal for applications where gentle, uniform heating is required, such as drying, ashing, or heat treatment of powders or delicate samples.
