Therser Wellman supply both gas-fired and electrically heated Pit Furnaces, suitable for a wide range of industrial applications and over a wide range of load shapes and sizes.
As the name suggest, the main body of the furnace is located in a pit, with the top of the furnace being the load/unload opening. Typically the top of the furnace sits just above shop floor level for ease of loading and unloading. Product is lowered into the furnace either directly or by way of jigs and fixtures for support whilst in the furnace.
Most are applied with protective/reactive atmospheres to prevent oxidization (In process) or enhance metallurgical properties within parts.
Typical applications include all types heat treatment processes in raw materials or component parts and in particular are used for long parts, loaded vertically where a full height, floor level, furnace would not be practical. Products from 3 to 6 metres long are common for this type of furnace.
Our Pit Furnaces can also be designed to meet the high performance demands within thermal processing standards such as AMS 2750G, GE and Rolls Royce standards, to name a few.
All of our robust and energy efficient furnace designs would be built around your process requirements/needs to give a solution tailored to getting the best out of your process.
