Operating principle
Designed to meet the most demanding situations, the 10-foot containerized load bench enables rapid intervention thanks to an immediately available test solution. Its compact, transportable format guarantees rapid commissioning and total flexibility, whether for multi-site operations, rental requirements or emergency situations. The container provides a fully secure test environment. Its optimized vertical ventilation ensures efficient heat dissipation, while limiting human and material risks during testing.
Equipped with the Advanced control system, the load bench is used to control and record the tests performed. Recorded data facilitates documentation of tests, proof of plant conformity and compliance with regulatory requirements.

Navi Advanced system
Intelligent control of your load banks
Designed for the most demanding environments, the Navi Advanced system is the integrated control unit developed by Delta-Résistel to optimize the control, supervision and operation of your load banks.
Thanks to its architecture combining an industrial PLC and an intuitive touch interface, Navi Advanced offers precise management of electrical tests while simplifying the user experience. Compatible with resistive, inductive and capacitive loads, it enables comprehensive testing of gensets, UPS, data centers, batteries or critical infrastructures.

Simple, powerful, scalable operation
The system integrates several control modes to suit every need:
- Manual mode for direct selection of power in kW, kVAR, kVA or power factor
- Automatic cycle mode for repeatable, self-contained test sequences
- Integrated measurement module with real-time display and CSV export of test data
- Optional advanced modes: automatic ballast, DC battery discharge, automatic power regulation or step control
