Rack-mounted load bank 21 kW

DATA 021

The 21 kW rack-mountable load bank is a key piece of equipment for data center commissioning. For your Data Center projects, this bench is designed to faithfully reproduce the energy and thermal behavior of computer rooms or servers under real operating conditions.

Its efficient design makes it easy to integrate in clean rooms or in confined spaces awaiting server racks.

  • Certified equipment for critical sectors

  • Uncompromising technical support and maintenance

Technical specifications

Operating principle

Its main role is to simulate a controlled electrical load in order to test the robustness and resilience of critical data center systems, including power supplies (UPS, PDUs, generators) and cooling systems. By generating heat dissipation equivalent to that of some or all of the servers in operation (“ Room Load Test”), the bench can also be used to assess the capacity of air-conditioning infrastructures to maintain optimal conditions (“ Thermal Load Testing“).

Thanks to precise power regulation (up to 21 kW), different load scenarios can be reproduced, from nominal operation to stressful situations (consumption peaks, temperature rises). This makes it possible to anticipate potential failures, validate back-up procedures and optimize energy management.

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.

Delta Resistel Load Bank remote control system

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
