Product Overview

Controlled Atmosphere 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.
Programtherm design and produce a variety of controlled atmosphere furnaces based on customer’s needs, and programtherm atmosphere furnace makes your heat treatment more successful.

Application Notes
  • However, toxic or explosive gasses are not recommended for use with controlled atmosphere 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 Controlled 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.
