RARA manufactures load banks, ranging from small portable units for testing generators to multi-megawatt<br />

designs for larger applications. Regular load testing, along with correct battery maintenance, is the best way of<br />

ensuring the reliability of standby power systems. It is routine for all newly-installed generating sets to have a load<br />

test during the commissioning process in order to prove the performance of the set and all its ancillaries-cooling<br />

system, exhaust system, switchgear and protection schemes.<br />

APPLICATIONS<br />

- Custom designed for your particular system<br />

- Several stages of assembly depending on shipping needs<br />

- Many sizes and applications available<br />
