Modifying the Atmosphere in an Oven

Concerns about sample oxidation are not restricted to furnace users, they are just as important to those working with samples in air convection ovens. It is for this application that Carbolite’s engineers designed the HTMA (High Temperature Modified Atmosphere) Ovens.
Three sizes 28, 95 and 220 litre capacity are each available with three choices in maximum temperature; 400°C, 500°C and 600°C. Each of which can be supplied with either; fully manual control of the temperature and electronically switched inert gas supply valves, or alternatively with a programmable controller that is able to run temperature profiles that are fully integrated with the automatic control of the gas supply valves.

Gas flow rates are regulated via flow meters which independently control the process gas and the purge gas flows.
