High Temp Door Gaskets – Expand Max Temp to +230C to 300C
Teflon Gasket for high temp applications (230°C+) Installed or sold separately. Prices and part numbers for the individual TFO oven models will be listed on the quote.
Increase Capacity. Extra Stainless Steel Shelves
Prices and part numbers for the individual TFO oven models will be listed on the quote.
How Much Product Can I Put Inside The Oven? Less is more. We recommend 50% capacity. Resist temptation. Over crowding the oven will inhibit air flow and cause inconsistent, longer drying time.
How Much Weight Will The Shelves Hold? The shelves are made of 304 stainless steel, we estimate about 50 to 75 lbs. max, depending on the oven you are using. Ask us about ways to increase shelf weight limit.
Can I Place Product Directly On Oven Floor? Yes.
Inert Atmosphere / Dry Air Purge
The N2 purge allows for an inert atmosphere within the oven’s interior. Generally, the purge cycle should force a volume of gas equal to 5 to 10 times the volume of the oven. The atmosphere within the oven is a mixture of room air and the purging gas until the purge cycle is completed. For this reason, the purge cycle should be finished before heat is applied to the chamber. Failure to properly complete a purge cycle may result in oxidation. A slight positive pressure should be maintained while running up to the set point temperature and throughout the heating portion of operation. Gas atmosphere should be maintained until the work load is below the temperature at which oxidation will occur. Oxidation is generally detectable by a discoloration seen in the product. 125C is considered the highest / safe temperature. Most materials can be removed from the oven at this temperature without discoloration. Requires a customer supplied N2 Source. The N2 purge system includes a flow meter, solenoid valve and event switch for operation the Watlow Controller. Part Number 9990023
The power exhaust provides rapid evacuation (return to ambient) of the oven. The power exhaust mounts to the top of the exhaust vent on the top of the oven. The power exhaust plugs into the switched 220V outlet on the back top of the oven.
