Danfoss controls for use in hazardous areas
In Ex areas, where people’s lives and high-value materials are at stake, safety, robustness and reliability requirements leave no room for compromise.
By working in partnership with Danfoss Industrial Automation, you can be confident that you will get precisely the controls needed to achieve optimum safety.
Our comprehensive range of intrinsically safe solenoid valves, switches, pressure transmitters and temperature sensors is designed and approved to be used in environments where there is a danger of explosion. Our products cover countless applications within the heating, marine & engine, hydraulic and vacuum industries. Solenoid Valves
Danfoss solenoid valves are designed for explosion-risk environments; i.e., where flammable liquids and gasses are produced, transported or tapped. They are delivered as a part programme, with a separate valve and coil, and can be quickly and simply assembled without tools, providing optimum product flexibility and availability.
Approved for use in Zone 1 in accordance with directive 94/9/EC (ATEX 100A) EN50014 and EN50028.

Switches
The Danfoss RT-E series, pressure, differential pressure and temperature switches, are designated for industrial refrigeration and general industrial application in explosive zones.
The range includes solutions for refrigeration systems with ammonia, hydrocarbons and other applications where flammable gases, vapours, mists and dust are likely to occur.
RT-E pressure and temperature switches for use in explosive zones incorporate an SPDT changeover switch, where contact position depends on the pressure or temperature values of the system.
Approved in accordance with 94/9/EC, ATEX directive, explosive
zone 1, for surface equipment, category 2.

Pressure Transmitters
The Danfoss Eex pressure transmitter programme offers reliable pressure measurement, even in harsh and demanding applications. It covers a 4-20 mA output signal, absolute and gauge (relative) versions, measuring ranges from 0-1 to 0-600 bar, and zero point and span adjustment with a wide range of pressure connections.
Some models are also available with integrated pulse snubber for protection against cavitation, liquid hammer or pressure peaks.

Temperature sensors and transmitters
Danfoss temperature sensors are designed for heavy-duty applications and are based upon decades of global experience within the marine industry and in refrigeration plants - among the toughest environments.
The range includes different versions with measuring ranges from -50°C to 800°C.
MBT 5113 and MBT 5116 for measuring and regulating exhaust gas in stationary and marine equipment like diesel engines, turbines and compressors, among others.
MBT 5250 and MBT 5252 for measuring and regulating temperature in piping systems and refrigeration plant on ships – or at all points where reliable, robust and accurate equipment is required.
These temperature sensors include Pt-sensing elements which are passive components and therefore classified as a simple apparatus. As such they cannot be approved according to the ATEX directive.

Eex installation
For safe installation of MBT 9110 transmitters in hazardous areas, the following points must be observed:
- The module must only be installed by qualified personnel who are familiar with national and international laws, directives and standards that apply.
- The transmitter is approved to be mounted in a metal enclosure Form B according to DIN 43729 that is providing a degree of ingress protection of at least IP 6X in accordance with EN 60529.
- The ATEX transmitter can be mounted in the standard B-head or in a heightened lid, but only the transmitter is ATEX approved and marked according to this.
