MAN Diesel & Turbo, France has acquired two 4500 KW resistive load banks and two 4.5 MVA integrated stackable step-down transformers from Crestchic, a Burton-on-Trent based business. The load banks and transformers are now used to test up to 6300 KW marine diesel engines, which MAN manufacture at their St Nazaire site in France. During testing, the engines are linked to a generator and the genset output is then tested. The engines are tested at 110% and for extended periods: one engine is initially run for 60 hours, then the genset is set up on the test bench and various load tests are run over the course of approximately one month.

This arrangement offers several benefits for MAN, including distinct advantages over their previous practices of using an MV directly connected 3MW HV resistor load bank, and of hiring test packages for larger-scale tests. The Crestchic load banks and transformers are available whenever MAN needs them, and have customised timing and control systems that were designed specifically to meet their requirements and to be compatible with other components used on the test bench. The Crestchic products also allow MAN to comply with noise level regulations — which was not the case with their previous solution — and have generated considerable cost savings compared with their previous rental costs.

Purchasing from Crestchic also allowed MAN to eliminate live element technology, which can cause earth leakage and short circuits in resistor elements, from its test bench. The technology involved was not available from any other French load bank suppliers. The design of Crestchic’s products, and the fact that their footprint could be reduced through stacking, were other key advantages.
