What is the lead time for standard and custom-built load banks?

Yes. VILVA supports customized load-bank solutions for projects with non-standard electrical, mechanical, or functional requirements. Depending on the application, customization can cover rated voltage, power capacity, loading steps, dimensions, control and display configuration, cooling method, installation structure, and other project-specific requirements.

The customization process begins with requirement analysis and solution design, followed by parameter calculation, material selection, production, assembly, commissioning, inspection, aging testing, calibration, and delivery. This allows the load bank to be developed around the customer's actual test equipment, operating environment, installation space, and acceptance requirements rather than forcing the project to fit a standard model.

For a customized quotation, customers can provide the required voltage, power, AC/DC type, loading method or steps, dimensions, installation environment, control requirements, quantity, and intended application. VILVA can then evaluate the technical requirements and propose a suitable configuration, including further customization where required.

VILVA provides after-sales technical support throughout the equipment service period, including troubleshooting and technical assistance for equipment operation and maintenance. Its customized-service process includes after-sales support and a lifetime maintenance system designed to help maintain stable equipment operation.

For overseas projects, initial troubleshooting can be carried out remotely based on the equipment status, operating conditions, alarms, and test data. Depending on the nature of the issue and project requirements, further technical service arrangements can be evaluated to support equipment recovery and commissioning.

To speed up troubleshooting, customers should provide the equipment model, fault description, alarm information, operating conditions, and relevant photos or videos. VILVA can then assess the issue and determine the appropriate technical-support approach.

Warranty coverage depends on the product configuration and the terms agreed for the specific order. VILVA provides after-sales support and maintains a structured lifetime maintenance system for its equipment.

For certain VILVA equipment programs, a standard full-unit warranty is provided, with separate warranty coverage for core components. However, warranty duration and coverage should be confirmed against the quotation, product model, and final sales contract rather than treated as a universal term for every load bank.

Warranty support is intended to reduce operational risk after delivery. Before ordering, customers can confirm the warranty period, covered components, exclusions, response process, and after-sales responsibilities for their specific project.

VILVA has project experience across data centers, power generation, UPS, energy storage, EV charging, and industrial power testing. Reference project cases can be provided upon request. The company also provides testing equipment and solutions for EV charging and new-energy applications, including a dual-standard EV charger testing project for manufacturers in Belarus. These projects demonstrate VILVA's ability to handle both standard equipment supply and application-specific testing requirements.

For customers evaluating a solution for a specific industry or project type, relevant case information can be discussed according to the application. Customers can share their equipment type, testing capacity, site conditions, and acceptance requirements so that VILVA can recommend a suitable reference solution.

VILVA operates under an ISO 9001:2015-certified quality management system and has obtained relevant CE, CQC, and CCC certifications listed on its official website. The company is also recognized as a National High-Tech Enterprise and a Specialized, Refined, Special and New Enterprise.

For export projects, the applicable certification and compliance documentation depends on the specific product, model, destination country, and market-access requirements. VILVA's products are exported to markets including the United States, Germany, Canada, and Southeast Asia, demonstrating experience in serving international customers.

Customers can provide the destination market, equipment model, and applicable standards in advance. VILVA can then confirm the available certificates and technical documentation for the selected equipment rather than applying the same certification package to every model.

VILVA uses core components from established brands, depending on the equipment configuration. These components are selected to provide reliable operation, electrical compatibility, and stable performance in demanding testing environments.

At the same time, VILVA independently develops and manufactures its alloy resistors in-house. This gives the company greater control over key components, product quality, accuracy, and supply availability, while reducing dependence on external suppliers for critical resistive elements.

This combination of internationally recognized components and in-house manufacturing capabilities supports VILVA's approach to stable, reliable load-bank production. The exact component brands and configuration can be confirmed according to the specific model and project requirements.
