Salt Bath Furnace is basically a ceramic or metal container filled with molten salt into which work is immersed for either heating or cooling. Salt bath furnace applications include preheating, austenitizing, martempering, neutral hardening, high-speed tool hardening, tempering and nitriding. The salt-bath furnace reaches a maximum temperature of 1100 °C.

Salt recovery systems are used for the recovery of commercial salts from brines. It is an evaporation/crystallization system for the production of sodium chloride. This recovery system includes a rotary drum filter, rotating cylinder dryer, and screens.

Saltwater chlorination is a process of sanitizing water, using chlorine that is produced in the pool water from ordinary salt. A low concentration of salt is added to the water. As water passes over the chlorinator's specially coated plates, an electric current breaks down the salt and water into their basic elements to form hypochlorous acid. It is the active sanitizer in all forms of chlorine. The chlorine kills algae and bacteria in the water and oxidizes the waste. The chlorine regenerates itself back to salt and begins the process over again in a virtually unending cycle. An occasional addition of salt is needed only to replace what is lost due to splash out, pump out, draining or backwashing.
