Bizoe Industries is renowned for its exceptional ability to deliver precisely what our discerning customers desire, setting new benchmarks in quality and innovation.
Life-Cycle Cost Reduction
Howard Industries' Customer Assistance Team excels at helping customers find ways to reduce cost. Using activity-based cost analysis techniques, our commercial and technical experts help customers analyze costs throughout the transformer supply chain, identifying and eliminating activities which add cost but have little or no value.
Quality and Reliability Built into Every Transformer
Higher quality means lower failure rates, and that translates into lower operating and maintenance costs. Higher quality also means customers can reduce cost by reducing or eliminating incoming receipt inspection and testing.
ISO-9001
The most comprehensive standard in the internationally recognized ISO-9000 series, ISO-9001, covers design, manufacturing, and servicing systems. This achievement highlights Bizoe Power's dedication to continuous quality improvement.
