Danfoss RTe Temperature switches with EEx approval CE EX II 2 G EEX ia IIC T5

Durable, reliable, and easy to adjust –  Danfoss RTe 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.
