DST P40I titanium pressure transmitter for in corrosive environments and aggressive media

DST P40I pressure transmitter for use in desalination systems, seawater cooling, and chemical processing

For use in corrosive environments, Danfoss offers the robust DST P40I pressure transmitter made of Titanium and with ceramic pressure sensing element. DST P40I is optimized for use in applications such as desalination systems, seawater cooling, and chemical processing. The transmitter housing is made from high-strength Titanium Grade 2, which is exceptionally resistant to a wide range of acids, alkalis, Sodium Chloride, and polluted water. The pressure sensing element is made from ceramic AI2O3 96% with superior chemical immunity. The pressure transmitter works following the piezo resistive principle, and the Wheatstone Bridge is printed directly on the inside of the ceramic diaphragm to ensure fast response time and a high degree of precision in measurements. DST P40I has been designed and tested to be highly resistant to continuous vibrations and cavitation in reverse osmosis desalination pump systems.

Danfoss solutions for brine mining

As global demand for lithium, magnesium, and food-grade salt surges, brine mining is emerging as a less environmentally disruptive alternative to conventional mining. But brine valorization is only economically viable if energy use and system complexity are kept in check.
Danfoss APP pumps and iSave ERDs form the foundation of ultra-energy-efficient SWRO and OARO systems. They deliver the precise, stable high-pressure performance needed to make brine valorization commercially and environmentally feasible.

Desalination

The global water challenges call for innovative solutions. Desalination is fast becoming a leading technology to transform sea water into clean fresh water for multiple purposes.
