Its semi-automatic operation and the ability to hold samples from 2 to 5 liters make it ideal for laboratories and industrial processes alike. The easy-to-use digital interface streamlines workflow and enhances usability.
FAQs of NACCTF - High Temperature Horizontal Tube Furnaces:
Q: How is temperature accuracy and uniformity maintained in the NACCTF-HTF tube furnace?
A: This furnace uses a sophisticated PID digital controller and high-quality Kanthal or MoSi2 heating elements to deliver precise temperature regulation. Its 120 mm ceramic fiber insulation and alumina ceramic chamber work together to maintain a uniform temperature with an accuracy of 1C and uniformity of 5C throughout the heating zone.
Q: What are the primary uses of this horizontal tube furnace in laboratory and industrial settings?
A: The NACCTF-HTF furnace is ideal for high-temperature applications, such as sintering, annealing, material testing, heat treatment, and thermal analysis. Its robust design supports both research experiments and industrial manufacturing processes requiring controlled thermal environments up to 1700C.
Q: When should the furnaces over-temperature protection feature be utilized?
A: Over-temperature protection is automatically engaged whenever the internal temperature exceeds the preset threshold, safeguarding both samples and equipment. Users should always enable this feature during operation, especially for prolonged or unattended heating cycles.
Q: Where can this furnace be installed and what installation requirements should be considered?
A: Designed for laboratory and industrial environments, the NACCTF-HTF should be installed in a well-ventilated area with access to a stable electric supply (220V/380V, 50/60 Hz). Ensure adequate clearance for airflow, routine maintenance, and safety checks. Its dimensions (800 x 500 x 450 mm) and weight (approx. 60 kg) should also be considered for spatial planning.
Q: What is the process for setting up and using the digital controller and timer?
A: To operate, input your desired temperature and timer duration on the digital controller. The PID system then manages heating using the selected setpoint and displays real-time values. The timer allows programming from 0 to 999 minutes, after which the furnace will automatically shut off or enter standby mode as programmed.
Q: How does the air cooling system benefit the operation of the furnace?
A: The integrated air cooling system promotes quicker cooldown periods and protects core components from heat-related damage, improving the longevity of the heating elements and insulation. This also enhances safety by maintaining manageable surface temperatures during the cooldown phase.
Q: What are the advantages of using Kanthal or MoSi2 heating elements in this furnace?
A: Kanthal and MoSi2 heating elements provide excellent thermal stability, durability at high temperatures, and resistance to oxidation. These materials ensure reliable, long-term operation and consistent performance even during repeated high-temperature cycles up to 1700C.
