Enough is enough: why you shouldn’t put up with poor rectifiers any more


You wouldn’t keep a car which kept breaking down, so why do so many tower owners battle on with sub-par rectifiers?

In an industry where towercos are spending as much as 60% of their opex on fuel consumption, capex-heavy investments such as deploying solar power or switching from lead acid to lithium batteries can help them to make gains and improve margins as they decrease their reliance on an unpredictable fuel supply chain. However, as much as towercos might spend on their power systems, they have still had to put up with unreliable rectifiers which have struggled to cope with the dust, heat and humidity at many locations. According to Mattias Karlsson, Vice President eSite at Flexenclosure, as many as 20% of rectifiers can fail each year in off grid and poor grid locations across Africa, Asia and the Middle East, adding costs through downtime, replacements and man hours across the maintenance cycle.
