Industrial Pit Furnace with Multiple Retorts and Cooling Towers

S.M. Engineering provides custom designed horizontal retort furnaces for a number of industries, suitable for processes where a controlled or protective atmosphere is necessary. Our retort furnaces feature re-circulating fan with unique sanseal cover design to evenly distribute temperature and atmosphere, low-watt density for longer element life, and 80/20 nichrome ribbon heating elements. They are equipped with a state of the art atmosphere safety system with automatic as well as manual nitrogen purge, and a maximum heating temperature of 1800 °F.

We offer a host of available options including additional retorts, multi flow meters, additional cooling towers, temperature chart recorders, along with high and low temperature controls and SCR power control for power conservation. Our furnaces feature shells that are composed of .188” thick reinforced hot rolled steel, and can accommodate materials up to 48" in diameter, and 48” in width. Complete furnace systems can be provided with lead times of 12 – 18 weeks.

S.M. Engineering is a leader in furnace design and construction, offering premium quality and optimal functionality to our customers. We adhere to all applicable industrial and safety standards, and stand behind our products with warranties and training.
