Application Description

General Industry

If you can´t find you application below, then you can select "General Industry". Here a switch will be selected to provide accurate operation and reliable alarm and safety functions in industrial applications for neutral medias like water, oil, air or steam.

Hydraulic power pack

Hydraulic power packs are stand-alone devices, as opposed to a built-in power supply for hydraulic machinery. Some power packs are large, stationary units and others are more portable. They have a hydraulic reservoir, which houses the fluid, regulators that allow users to control the amount of pressure the power pack delivers to a valve, pressure supply lines and relief lines, a pump and a motor to power the pump. The pressure is controlled by either switch or sensor.

Water pump

Pumps are used to move water from one position to another, in some cases the main purpose is just to move the water and in other cases the pumps are also used to build up a desired pressure. Pressure switch or sensors are to start the pump if the pressure in the system falls below a preset value. If there is more than one pump in the set the switches can be used to start the next pump in case more water is needed in the system. Can also be used to stop the pump if there is no pressure in the suction line to protect the pump from dry running.

Hydrofor/Pressure tank

Because wells rarely have positive pressure, equipment is required to draw the water from the well. Well systems generally consist of the well itself, a pump, a pressure switch for automatic activation of the pump and a pressure tank. The pump sends water from the well to the pressure tank for temporary storage. The pressure tank then holds the water until it is needed in the house. Pressure tanks generally come in three different forms, those with an air-filled bladder, those with a wafer between the water and the air inside and those with no bladder or wafer at all. The pressure tank provides immediate access to well water without having to manually turn on the pump. The pressure tank/pressure switch combination allows the pump to operate automatically in an intermittent way, running only when needed. This also reduces the amount of time the pump is running, thereby extending the life of the pump.

Booster

Booster set pumps systems are needed where the main water supply does not provide sufficient head or flow for the total demand. The purpose of the application is to maintain a constant water pressure, even if the water demand changes during the day. A switch is needed to control the pressure .

Irrigation systems

There are various types of irrigation techniques and they differ in how the water obtained from the source is distributed within the field. In general, the goal is to supply the entire field uniformly with water, so that each plant has the amount of water it needs, neither too much nor too little. The different types of irrigations systems are: Drip-, sprinkler-, center pivot-, lateral move- and subirrigations systems. The pressure switch is controlling the water pressure.

Air compressor (1-phase switch)

The Air Compressor industrial sector includes a huge range of equipment from very small units used for medical and dental uses through to very large industrial compressors operating in the kilowatt power band. Small units are self-contained and operate at the site of use. Larger units can be either centralized (e.g. To supply a factory with many end uses) or self-contained (specific to one piece of equipment). From a safety perspective a pressure switch is needed to monitor control the system pressure. In this section we offer 1-phase switches.

Air compressor (3-phase switch)

The Air Compressor industrial sector includes a huge range of equipment from very small units used for medical and dental uses through to very large industrial compressors operating in the kilowatt power band. Small units are self-contained and operate at the site of use. Larger units can be either centralized (e.g. To supply a factory with many end uses) or self -contained (specific to one piece of equipment). From a safety perspective a pressure switch is needed to monitor control the system pressure. In this section we offer 3-phase switches.

Steam boilers

A boiler or steam generator is a device used to create steam by applying heat energy to water. Although the definitions are somewhat flexible, it can be said that older steam generators were commonly termed boilers and worked at low to medium pressure (1–300 psi/0.069–20.684 bar; 6.895–2,068.427 kPa) but, at pressures above this, it is more usual to speak of a steam generator. A boiler or steam generator is used wherever a source of steam is required. The form and size depends on the application: mobile steam engines such as steam locomotives, portable engines and steam-powered road vehicles typically use a smaller boiler that forms an integral part of the vehicle; stationary steam engines, industrial installations and power stations will usually have a larger separate steam generating facility connected to the point-of-use by piping. A pressure switch is used for providing accurate operation and reliable alarm and safety functions.

Boiler room

In boiler rooms, accurate monitoring of steam/hot water installations, heat exchangers and water treatment equipment for feed water is vital. Danfoss pressure controls offer reliable surveillance and accurately regulation.

District heating

District heating substations require automatic surveillance of water pressure and temperature to ensure a reliable supply of uninterrupted district heating.

Marine

When talking about marine a whole ship comes to mind. A ship includes most of the applications found on shore just concentrated on a limited space. The applications span from sewage water to treatment of the exhaust gas. Although Danfoss has products suited for many of these applications, we are concentrating on the equipment placed in and around the engine room and propulsion system. Switches are used in marine applications on engines, propulsion, air compressors, boilers, fuel treatment, oil separators, incinerators. Thrusters and power packs.
