MDI Inc. Our Company!
See all MDI Sewage Products
Mercury Displacement Industries Incorporated, better known in the industry we serve as MDI, was incorporated in Michigan in 1975. The primary product line is switch gear components including mercury type contactors, tilt switches and liquid level float controls.
Contactors are rated from 30 to 100 Amperes and are commonly used in various heating, lighting, and many other industrial applications including high voltage ultraviolet type loads. The contacts are encased in hermetically sealed stainless steel tubes to provide reliable switching for millions of operations. All basic units are UL, CSA, and CE approved.
The liquid level control floats are manufactured with mechanical or mercury switches. The float material is High Impact Polystyrene for normal alarm, sump pump or water applications, For sewage, 1 or 2 H.P. or high temperature, 86°C (186°F) requirements Acrylonitrile Butadiene Styrene, (ABS) float material is provided.
MDI has 40 to 50 employees and markets products through distributors, representatives or direct to OEM accounts throughout the world.
