KAAS CupelPro CF Series – High-Temperature Cupellation Furnace

Models: CF-50; CF-100
Brand: KAAS
Product Type: High-Temperature Cupellation Furnace
Application: Ash refining, pyrometallurgical assays, precious-metal analysis, laboratory testing and high-temperature sample processing

---

Overview

The KAAS CupelPro CF Series High-Temperature Cupellation Furnace is designed for laboratory experiments and production applications involving ash refining and pyrometallurgical assays.

With a rated temperature of up to 1200°C, the furnace provides a controlled high-temperature environment for cupellation processes and other applications requiring stable thermal conditions.

The furnace features a durable zinc anneal sheet-steel cabinet lined with alumina fire bricks and insulating refractory bricks, with additional Vermiculite insulation to support effective heat retention.

A K-type thermocouple provides accurate temperature sensing, while the electronic automatic temperature-control system supports stable furnace operation.

The furnace is also equipped with a pneumatic rising door operated by foot control, allowing convenient operation while keeping the hot furnace door away from the operator. An integrated observation window allows users to continuously monitor the cupellation process without opening the furnace door.

The CupelPro CF Series is available in CF-50 and CF-100, providing different muffle sizes and cupel capacities for different processing requirements.

Furnace Construction

Cabinet

The KAAS CupelPro CF Series uses a cabinet constructed from zinc anneal sheet steel.

The furnace is mounted on a console fabricated from zinc anneal sheet steel, while the external surface is finished using electrostatic spraying for a durable industrial appearance.

Refractory Lining

The hot face of the furnace chamber is constructed using alumina fire bricks, backed by insulating fire bricks.

The furnace is additionally supported by Vermiculite insulation board to improve thermal insulation and help retain heat within the chamber.

This refractory construction is designed to support operation at temperatures of up to 1200°C.

---

Temperature Control System

The CupelPro CF Series uses an electronic automatic temperature-control system with a K-type thermocouple.

The thermocouple measures the furnace temperature while the control system manages the heating process according to the required operating temperature.

With a rated temperature of 1200°C, the furnace provides the high-temperature environment required for cupellation and pyrometallurgical assay applications.

---

Pneumatic Door System

The furnace is equipped with a pneumatic rising door operated by foot control.

This arrangement allows the operator to control the furnace door using a foot-operated mechanism rather than manually handling the door.

The rising-door design helps keep the hot furnace door away from the operator during operation, providing more convenient handling when working with high-temperature processes.

---

Observation Window

The CupelPro CF Series includes an observation window that allows users to monitor the cupellation process without opening the furnace door.

This provides continuous visual observation during processing while maintaining the furnace's closed operating environment.

 

---

Cupel Capacity

The two models provide different cupel capacities according to the size and quantity of samples being processed.

CF-50

50 × 6a, 7a, 7as

Suitable for applications requiring a smaller cupel-processing capacity.

CF-100

100 × 6a, 7a, 7as

Provides a larger cupel capacity for applications requiring higher-volume sample processing.
