CE Industrial Vacuum Muffle Furnace Up To 1600C With Diffusion Vacuum Pump Unit

Industrial Vacuum Muffle Furnace Up To 1600C With Diffusion Vacuum Pump Unit

Overview for High Vacuum Muffle Furnace

PV L216/17 is an controlled Atmosphere VACUUM furnace, the furnace chamber structure was built in sealing type, which makes it could be working under Vacuum, Nitrogen and other inert gases atmosphere situation, and the chamber insulated with 1800# high quality alumina lining board, heating elements are powerful MoSi2 rods, the temperature is controlled by high precision SCR (Silicon Controlled Rectifier) digital controller with accuracy ±1°C and many segments programmable up to 1600°C (in air 1700C).

Controlled Atmosphere Furnace provides an perfect 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.

Programtherm designs and produces a variety of controlled atmosphere furnace models based on customer’s needs, and Programtherm atmosphere furnace makes your heat treatment more successful.

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

Technical Specifications

Application Notes

• However, toxic or explosive gases that may generate from the sample during the heating are not recommended for use with this high temperature 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 PA Controlled Atmosphere muffle furnace is around 90000 Pa with hose barb connections. Please keep in mind that our PA 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
