What happens if you decide not to choose OPP?

This is what can happen when you do not specify the right equipment for the African climate.

There are two very important things you must consider when you invest in Power Factor equipment for your African business.

  1. Temperature
  2. Altitude


You know yourself it’s not unusual for outdoor temperatures in Southern Africa to reach 50 degrees. But inside your electrical control room, temperatures can become intense, and inside the cabinets it’s gets warmer still. Without proper cooling, ventilation circuits overheat and in extreme cases (as you see above) the components actually melt.

That’s why we insist on installing forced air ventilation on all our equipment as standard. And on our larger units we fit dual forced air systems. For your unit, it’s like having it’s own air-conditioning system and guarantees this will never happen to you.


Most major towns and cities in Southern Africa are at least 1000 metres above sea level, some are close to 2000.

This is the the single most important consideration in your choice of Power Factor Correction Equipment.

The reduced air pressure at higher altitudes means that low grade capacitors will actually split open and spill acid. That’s why we only use Vishay High Specification Capacitors. They’re amongst the best in the world.

In the table below you can see a comparison of all the companies available to you. We’ve compared all for the Key Performance Indicators that are most important in making your choice.
