Sevcon Service & Repair Forum
: Our industrial unit, a 10,000 sq ft facility used to manufacture high-pressure hydraulic pumps, has experienced a catastrophic failure in its main control system, rendering it completely unusable. Since the control system is crucial for ensuring safe and efficient operation of the machinery, our production has come to a standstill, resulting in significant financial losses. We have assessed the potential repair costs at a minimum of $50,000, with the possibility of even higher expenses depending on the extent of damage and availability of replacement parts. However, given the critical nature of this unit and its long-term reliance on our manufacturing processes, we are exploring alternative options such as rebuilding the control system or seeking out a pre-existing, similar unit for a quicker solution.:
