If you want the best atmosphere muffle furnace for your application, this GCF1400 series model is your best bet. It’s imbued with the highest quality alumina fiber insulation, which contains Mitsubishi Silicon carbide (SiC) heating elements. This is housed in a double-walled, steel, internal housing that traps the heat within. It isn’t only high-quality components that puts this furnace above the rest. A Eurotherm 3204 with 5 on-board process recipes (48 parameters per recipe) digital controller delivers precise temperature control. It’s precise but also user friendly. A built-in, RS485 digital communications port and USB adaptor allows you to control or monitor operations straight from your PC. You can even save or export test results.
This furnace is so advanced that multiple atmosphere processes are possible within a single cycle. Since mixing gases within the chamber is so important, the furnace comes with gas inlets and outlets with stainless-steel ball valves. These outlets can be ignited to burn off gas. To ensure airtightness, the furnace door is sealed with a high temperature silicone gasket. But that’s not all. A built-in, stainless-steel, water-cooling panel helps protect the gasket when the furnace is under heavy use. Another feature, a built-in ammeter and dual voltmeters allow for easy monitoring and troubleshooting, while it’s type S thermocouple ensures a long lifespan. Note that each furnace is welded and tested for airtightness before it leaves our facility. Safety features include overheat and power failure protections. 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.
Multiple gas inlets and outlets with stainless steel ball valves. Flow meter to control inbound and outbound gas flows. Outlets can be ignited to burn off gas.
Furnace chamber is welded and oil leak tested to ensure air tightness. Furnace door is sealed with high temperature silicon gasket.
Built-in stainless steel water-cooling panel protects door sealing gasket when furnace is under heavy use.
Microprocessor based self-tuning PID control provides optimum thermal process with minimal overshoot.
Multiple atmosphere processes in a single cycle are possible (ex: binder burn out in air and parts sintering under rough vacuum or inert gas environment.)
Built-in ammeter and dual voltmeters for easy monitoring and troubleshooting.
