Danfoss High Pressure Pumps (formerly Danfoss Nessie) offer their unique water hydraulics product programme and other high pressure water solutions. – The Danfoss High Pressure Pump (Nessie) product programme covers more than 40 patents!
For the complete and compresensive range range of Danfoss High Pressure Water equipment including pricing and availability please go to our dedicated High Pressure Water Equipment website.
The Danfoss HPP range main focus is on many distinct solution areas with targeted products and expertise.
These areas are:
Fire fighting:
Using high-pressure water mist for fire fighting systems is the most efficient way to extinguish fires. The low quantity of water required means consumption can be reduced to one seventh of the volume used by conventional sprinkler systems.

Reverse osmosis:
Reverse osmosis is the process of turning sea water into drinking water. Typical desalination applications are on yachts and remote areas (eg islands). The Danfoss duplex/super duplex pumps generate the pressure needed to send the incoming salt water through the membranes and as a result drinkable water is separated from the salt water.

Wood processing:
Using high-pressure water mist to lubricate and to cool saw blades in a saw mill prevents resin from sticking to the blades and reduces friction, which means increased productivity and lower energy cost. Sawdust levels are reduced too, resulting in a better working environment. High-pressure water mist is also used for humidity controls in drying kilns.

Humidification:
High-pressure water mist can be used in a variety of humidification applications, such as humidification in open space, in air handling units and for adiabatic cooling.NOx control and turbine efficiency:
High-pressure DI water mist can be sprayed into the air intake of diesel engines for ships or gas turbines for power generation to reduce the NOX pollution and to increase the efficiency of the turbine.

Industrial cleaning:
Solenoid valves for general usage are used in a number of industrial cleaning applications like automatic car wash systems, stationary high-pressure washers, snow-making machines and parts cleaning. Cylinder and motor functions can be performed with ordinary tap water as the hydraulic fluid. Combining that with their internal system house, representing a strong technical and application knowledge, you have come to the best place for high-pressure water solutions.

Danfoss RTe ATEX Explosion proof pressure and temperature switches
Durable, reliable, and easy to adjust – Danfoss RTe pressure and temperature switch offers the same features as the RT – but now has EEX approval for use in areas with high risk of explosion
Trusted and approved
For many compressor manufacturers, the Danfoss RT switch is a trusted component, renowned for its safety and reliability. With a manual reset feature, the RT is recommended for safety shut-offs – often where other controls have failed. The customers were requesting an EEX-approved version of this product for use in situations where explosions are a risk factor – and now the introduction of the RTe is set to meet their demands.
The RTe has CE and ATEX approvals:
•CE EX II 2 G EEX ia IIC T5
•CE marked, according to EN 60947-4/-5
•CE marked, according to PED 97/23/EC category IV, safety equipment: RTE6AEW, RTE6AEB, RTE6AES
•CCC, China Compulsory Certificate
Mehrer Kompressoren, a large German manufacturer of piston compressors, was one of the first companies to adopt the RTe. Mehrer were already using Danfoss RT switches, but needed EEX-approved switches for situations where flammable gases and vapours are present in their production processes. Danfoss responded to its customer’s needs by developing the EEX-approved RTe with specifications such as metal housing, which make it ideal for handling explosive gasses safely.
The RTe is available as a temperature switch (thermostat), a pressure switch as well as a differential pressure switch. For further technical specifications please see data sheet below.
Mehrer adopted the EEX-approved RT in favour of their previous switch, supplied by another manufacturer, because it is easier and quicker to install. It requires considerably less time to wire and make adjustments.
Danfoss always try to respond to customer demand: with the RTe, a new and improved product has been added to the portfolio and it has already received positive feedback from customers, among them Mehrer Kompressoren who is satisfied with both the process and the product.
