Controlled Atmosphere Muffle Furnace 1300°C (16x16x16″ 64L)

PA L64/14 is an atmosphere muffle furnace, mainly used for material synthesis in lab or research institute. The furnace structure was built in dual steel case, sealing type, which makes it could be working under Vacuum, Nitrogen and other inert gases atmosphere situation, and the chamber insulated with 1600# high quality alumina lining board and equip a 310S box inside prevents corrosive gas from erosion the chamber, heating elements are powerful SiC rods, the temperature is controlled by Shimaden digital controller with accuracy ±1°C and many segments programmable up to 1400°C.

Product Overview

Atmosphere Muffle Furnace provides an environment for various purpose in many heat treatment experiments, providing the controlled temperature and atmosphere specific projects require. The controlled atmosphere ensure to complete tasks that require suitable temperatures. This is the best way to ensure the successful outcome of your project because it is sealed tightly to ensure the proper environment.
One of the main components of the atmosphere furnace is the correct mixture of gases. The precise measurement of each gas is essential to the success of your project. You can use a separate chamber to mix the gases, which are then pumped into the furnace chamber where the work will be completed when they are done mixing. It is essential that the separate chamber that holds the gases does not receive any outside air because it could throw off the gas mixture and render your project useless.

Main Features
  • Tmax 1400°C
  • Dual steel structure, air tight chamber
  • Multiple gas inlets and outlets with stainless steel ball valves
  • Dual door design, sealing with silicon gasket
  • 310SS box inside prevents corrosive gases from erosion the ceramic fiber chamber
  • Equip a water circulation device for furnace cooling
  • SiC heaters heating from 2 sides
  • Precise PID controller with progrmmable 32 segments
  • Long life type S thermocouple
  • CE standard
Safety Measures
  • Built-in ammeter and dual voltmeters for easy monitoring and troubleshooting.
  • Overheat protection shuts down the furnace if temperature is outside of acceptable range (refer to controller’s manual) or when the thermocouple is broken or malfunctions
  • Power failure protection resumes furnace operation right after the point of failure when power is reestablished
  • Microprocessor based self-tuning PID control provides optimum thermal process with minimal overshoot

Application Notes
  • However, toxic or explosive gasses are not recommended for use with atmosphere muffle furnace without necessary safety controls and supervision.
  • Small cracks may appear on the surface of the refractory ceramics over extended use. This is a normal occurrence and the cracks may be repaired with alumina coating
  • Ultimate vacuum level for PQ Atmosphere muffle furnace is around 20000 Pa with hose barb connections. Please keep in mind that our PQ atmosphere furnaces are NOT designed to be vacuum furnaces, the vacuuming part is mainly for users to pre-vac the chamber, before putting in inert or other protective gases, if you have special request on vacuum level, please order our professional vacuum furnaces.
