his GCF1200 series controlled atmosphere muffle furnace is made of the highest quality parts, equating to precise, reliable results each and every time you use it. Sweden’s famous Kanthal heating elements inhabit its core, embedded within rugged Mitsubishi alumina fiber insulation. The impressive heat generated is contained in a double-walled, steel internal housing. Besides this, a high temperature silicone gasket seals the furnace door. But it goes beyond that. A built-in, stainless steel, water-cooling panel protects the door’s sealing gasket when the furnace is under heavy use.
A Eurotherm 3204 5 on-board process recipes (48 parameters per recipe) digital controller offers perfect temperature control. On top of that a 28-segment, self-tuning, PID control provides optimal thermal processing, while minimizing overshoot. One exciting option, you can directly control and monitor the furnace from your PC, through an RS485 digital communications port and USB adapter. You can even save or export test results. A built-in ammeter and dual voltmeters allow for easy monitoring and troubleshooting, while a type K thermocouple ensures a long lifespan.
Multiple gas inlets and outlets are included. Each has a stainless-steel ball valve. Inbound and outbound gas flows are controlled by a flow meter. Outlets can even be ignited in order to burn off gas. One important feature, multiple atmosphere processes are possible in a single cycle. This furnace comes with two safety features: overheat protection and power failure protection. It and all of our furnaces are CE compliant.
The benefits of an controlled atmosphere furnace
An atmosphere furnace provides the perfect environment for various procedures in many laboratories, providing the controlled temperature and atmosphere specific projects require. The controlled atmosphere is desired to complete tasks that require exact temperatures with no room for error. 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.
Proper temperature control is vital to the success of your project as well. Temperatures that are too high or too low will cause problems with the process and could cost your company a significant amount of money. Across International furnaces come with built-in 28-segment PID digital temperature controller for accurate monitoring and consistency.
