Pit Furnace

Gas Fired/Electric Pit Type Furnace by Smelter

Our pit furnaces are designed and manufactured for very small to very large workpieces. Pit furnace is available with or without retorts in customized dimensions and variations to carry out the complete heat-treatment process.

Pit furnaces are used in various applications like gears of wind power generation and bearings in the railway industry for gas carburizing and nitriding.

Types of Pit Type Furnace

Low Temperature Pit Type Furnace

Pit type air circulation furnaces are installed with the opening at ground level or just above it. These are low-temperature furnaces with operating temperatures up to 600°C.

High Temperature Pit Type Furnace

Pit type sealed retort furnaces are of a cylindrical design vertically erected with a positive sealing mechanism on top in order to contain and preserve heat and atmosphere during a process cycle.
