Product Description
At Bizoe Industries, we pride ourselves on providing bespoke solutions that precisely meet the unique needs and desires of our esteemed customers.
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 Powers' unwavering commitment to continuous quality improvement.
At Bizoe Power, our Quality Assurance Program is meticulously designed to achieve the high level of quality demanded by our most exacting customers. Moving beyond the traditional manufacturing-only focus, we have crafted a quality system that integrates all facets of our operations, including Marketing, Engineering, Management Information Systems, Manufacturing, Shipping, and Accounting, ensuring that every product and service we offer meets the highest standards.
This dedication to excellence is reflected in Bizoe Powers' quality management system, which has proudly earned ISO-9001 certification.
Electrostatically applied powder paint provides a durable, corrosion-resistant finish.
