A true picture of the performance of your installations

Delta-Resistel resistive/reactive load banks combine resistive and reactive loads to accurately replicate the real-world operating conditions of electrical installations. They enable equipment (generators, inverters, data centres) to be tested under varying power factors, simulating the stresses associated with inductive loads.
Designed for demanding environments, our load banks guarantee reliable, accurate and representative testing, ensuring the performance, stability and compliance of your critical installations.
An ideal solution for testing under real-world conditions, whether during commissioning or maintenance.

4 key features of the range:

• Adjustable power factor
• Simulation of real loads
• Precise and modular control
• Robust and secure design

Reliable solutions for electrical testing and maintenance.

Delta-Resistel resistive load banks are designed to ensure the performance, reliability and safety of your electrical installations. Used for testing generator sets, uninterruptible power supplies (UPS) and power distribution systems, our equipment simulates real-world loads to validate the proper functioning of your installations under controlled conditions.

Thanks to a robust design and high-quality components, our load banks offer optimal heat dissipation, high load accuracy and ease of use, making them suitable for maintenance operations as well as factory or on-site testing.

Delta-Resistel offers a comprehensive range of solutions, from portable load banks to high-power systems.

Optimised to meet the requirements of the industrial, commercial and energy sectors, our resistive load banks are the ideal solution for testing, monitoring and securing your electrical equipment whilst ensuring compliance with current standards.

3 key features of the range:

• Quiet operation
• Robust design
• Features

Secure your infrastructure before your servers arrive

Before installing servers and critical IT equipment, the reliability of the electrical and cooling infrastructure must be flawless. Commissioning using load banks is a key step in ensuring the future performance and availability of your data centre. These full-scale tests enable you to validate electrical and thermal performance, anticipate risks, and secure the facilities before integrating sensitive, high-value equipment. The result: a data centre that is ready to operate and reliable from day one.

3 key features of the range:
– Tests carried out as close as possible to the servers’ final location
– Ease of implementation
– Flexibility and modularity

Liquid-cooled load banks

Energy requirements in data centres are on the rise; new servers incorporate increasingly powerful central processing units and graphics cards, thereby reaching power densities where air cooling is no longer sufficient to cool the racks properly. That is why, today, nearly 40 % of data centres have adopted liquid cooling technology in one form or another. Our liquid-cooled load banks enable you to meet these new testing and validation requirements for data centre infrastructure under realistic conditions that reflect actual operation.

3 key features of the range:

• Quiet operation
• No heat emission
• Reduced auxiliary power requirements
