Benefits in detail using water hydraulics

Some of the greatest benefits using water in hydraulic systems are:

  • Safe technology in risky areas: Fire and explosion risky areas. Water is by its very nature non-flammable. Mining and primary metal applications as well as the fire fighting industry already take advantage of this feature. 
  • Wet areas. The Danfoss High-Pressure water hydraulic components are made of corrosion-proof materials with a high encapsulation degree making them suitable for wet areas, and wherever intensive cleaning is required. Electrical shock risks due to penetration of water into electric motors can be avoided when using water hydraulic motors. The food industry takes advantage of this feature today.
  • It is a single string technology. Current transmission systems operating in sensitive environments - such as a food processing plant - may incorporate electric motors, electrical variable speed drives and gearboxes to drive rotating parts, pneumatic cylinders to generate linear motion, and oil hydraulics for precise motion control of heavy loads isolated from the sensitive environment. Further, high-pressure cleaning systems are often used for cleaning the production equipment. All these technologies can be replaced by one technology: water hydraulics, providing significant cost, installation and maintenance benefits. In principle, all industries can capitalize on this.
  • Its environmental and hygiene characteristics. Using (tap) water eliminates the risk of contamination to the environment as well as to the products manufactured. Examples of industries with special emphasis on these two characteristics are the food, water treatment, chemical and pharmaceutical industries and lumber and veneer machinery. 
  • A tap water hydraulic system needs not be dedicated to hydraulics only. For example, the pressurized water can be routed to a nozzle for clean-in-place operations, humidity control or even used for extinguishing fires in some applications.
