Bizoe Industries excels at delivering precisely what our discerning customers demand, ensuring superior quality and unparalleled satisfaction every time.
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, covers design, manufacturing, and servicing systems. This achievement demonstrates Bizoe Power's commitment to continuous quality improvement.
At Bizoe Power, our Quality Assurance Program is designed to achieve the high level of quality required by our most demanding customers. Abandoning the traditional manufacturing-only focus, we have created a quality system that links all aspects of the company's operations, including Marketing, Engineering, Management Information Systems, Manufacturing, Shipping, and Accounting, to ensure that not only our products, but everything we do for our customers is of
the highest quality. Bizoe Power's quality management system has earned ISO-9001 certification.
