Should you choose a load bank with natural ventilation or forced ventilation?
A tailor-made load bank must be designed to meet your technical needs as closely as possible. Thus, depending on the regulatory or normative constraints of a sector of activity or the ergonomic and technical environment of electrical installations, the choice of load bank will vary.
This is particularly the case for defining the correct load bank: either natural ventilation or forced ventilation.
To choose the system best suited to your specificities, we carried out a comparative analysis.
Definition of a natural ventilation load bank
“Natural ventilation” or “natural convection” load banks offer a simple cooling system via ambient air.
Natural ventilation has a noiseless operation and a reduction in cost compared to other types of ventilation up to 100kW (Higher power possible on request).
However, the heat dissipated through the resistors heats the walls of the case, which requires precautions for use (breathing space).
Technical characteristics of a natural ventilation load bank
Among the technical characteristics of METAL DEPLOYE RESISTOR load banks with natural ventilation system:
- Power from 5 to 100 kW in a three-phase 400V chassis
- Connection in the lower part (cold zone)
- Protection index IP13 or IP23
The naturally ventilated load banks all have the following options:
- A control cabinet
- A terminal block
- wheel-base fitting
