DEMA History
Bela and Hermann Deutsch founded DEMA in 1956 soon after they formed their first company, Standard Machine and Manufacturing. DEMA was born out of customer requests for a device to dilute chemicals accurately and automatically. During DEMA’s first year the “proportioner” was introduced to the institutional cleaning market. Large chemical companies approached DEMA to build various products that would allow them to correctly dilute their cleaning chemicals. Since the beginning DEMA has introduced thousands of different proportioner models, with the primary goal of offering our customers the most reliable, safest and accurate way of dispensing concentrated chemicals. In addition to our complete range of chemical dispensing equipment, DEMA has also designed and manufactured a line of solenoid valves, injectors and other fluid control devices to meet many industrial applications.
During DEMA’s early years our focus was water driven dispensing equipment. As technology advanced, DEMA entered the electronic dispensing market, and now produces a broad range of electronic dispensers for kitchen, food service, laundry, industrial and specialty applications. These dispensers are designed to meet the needs of our worldwide customer base, specifically holding quality and safety at the highest standard and helping to lower the total cost of equipment ownership.
DEMA is committed to the complete satisfaction of our customers throughout the world. DEMA has expanded our facilities in Missouri, Pennsylvania, the Netherlands, and Australia plus added warehouses and representative offices in Brazil and China. All of our expansions have led to better service and satisfaction for our growing global customers.
DEMA is continuously updating our product range to meet the needs of our global customers. From 2 people in 1956 to more than 300 employees today, DEMA continues to grow and maintain the status as a leading provider of chemical dispensing and fluid control equipment.
