NES Cathodic Protection Rectifiers
We are the exclusive authorised distributor of NES Nová Dubnica products in Australia. NES is a European leader in power electronics, manufacturing high-quality cathodic protection rectifiers, impressed current power supplies, and switching drainage units from their facility in Slovakia since 1992.
Through our exclusive arrangement with NES, Australian asset owners, contractors, and corrosion engineers can now access the full NES product range with local support, engineering expertise, and integration with Datacell's DataScape monitoring platform.
Whether you are protecting buried pipelines, storage tanks, marine structures, or reinforced concrete, NES equipment is engineered to meet the demands of challenging Australian environments.
Product Range
SZK Series — Air-Cooled CP Rectifiers
Switchmode impressed current cathodic protection rectifiers in a robust steel enclosure. Available in a wide range of output voltages and currents to suit pipeline, tank, and structural protection applications.
SZKO Series — Oil-Cooled CP Rectifiers
Oil-cooled cathodic protection rectifiers for high-duty-cycle installations and environments requiring superior thermal performance and reliability.
Switching Drainage Units (SDU)
Automatic and manual switching drainage units for stray current mitigation on DC traction networks. Fully compatible with VEC electrolysis committee requirements for the Victorian rail network.
AC/DC Switching Power Supplies
High-efficiency IGBT-based switching power supplies with output ripple optimised for cathodic protection and galvanic plant applications. Efficiency up to 92%.
Remote Monitoring Integration
All NES rectifiers can be integrated with Datacell's DataScape platform via Modbus RTU/TCP, enabling 24/7 remote monitoring, alarming, and trending from a single dashboard.
Custom & Special Power Supplies
NES designs and manufactures custom power supplies for special applications including electroplating, DC/DC converters, battery chargers, and DC UPS systems.
