400 kW Air Cooled Load Bank

Key Features

Surgical Precision & Instant Proof

Stop forcing approximate load steps or guessing if a unit met spec. With 1kW step resolution and Class 1 (0.1% accuracy) 4Hz data logging, you get absolute control over your test parameters and capture critical transient drops standard loggers completely miss. You deliver pinpoint power accuracy while building an unassailable data trail for your clients.

Zero-Touch Mass Deployment

Eliminate the time-draining headache of manual IP configuration and field setup. Powered by the VCS 2.0 platform, the 400 kW air cooled resistive load bank features automatic network discovery that connects up to 240 units instantly across star, daisy-chain, or hybrid networks including Crestchic liquid cooled load banks. It even automatically balances load distribution across mixed-voltage units, letting you scale massive commissioning tests in minutes instead of hours.

Instant, Audit-Ready Compliance

Turn hours of tedious post-test data wrangling into a single click. Live visual tracking displays color-coded ISO 8528-5 frequency bands during the run, allowing operators to spot and correct potential failures before the test ends. Once complete, the platform automatically generates polished, client-ready PDF reports certified against ISO, IEC, NEMA, and ASHRAE standards.

Intelligent Loop Monitoring

This is more than just a heater; it is a diagnostic tool. The built-in 10 inch HMI and PLC system provide real-time monitoring of flow rates, temperature differentials (Δt), and system pressure.

Maximize Testing Efficiency with Modbus TCP/IP Automation

Modbus TCP/IP is the global industry standard for open industrial protocols. C2CPS units equipped with VCS 2.0 expose all internal registers directly over a standard Ethernet connection. This allows your centralized Building Management System (BMS), Supervisory Control and Data Acquisition (SCADA) system, or Programmable Logic Controller (PLC) network to issue control commands and read real-time telemetry from your entire load bank fleet simultaneously.

Dual-Action Control & Monitoring

• Automate Testing Sequences: Execute complex, step-by-step transient response tests instantly without manual intervention.
• Dynamic Load Stepping: Inject precise target kW or kVA load steps instantly to simulate real-world grid anomalies.
• Tolerance Safeguards: Set exact, real-time voltage and frequency boundaries to protect critical facility infrastructure.

High-Speed Telemetry 

• Electrical Metrics: Capture synchronized 3-phase voltage, current, frequency, and active/reactive/apparent power.
• Safety Diagnostics: Pull instant alarm faults to isolate and resolve system issues before they cause downtime.

The Engineer’s Perspective

• Sub-Millisecond Data Resolution: Traditional manual logging misses brief transient voltage dips. Modbus TCP/IP captures high-speed electrical changes instantly, which is critical for Tier III and Tier IV data center certification.
• Reduced Hardware Footprint: Standard Ethernet connections eliminate costly, specialized proprietary wiring, converters, and specialized intermediate gateway blocks.
• Native Hardware Interoperability: Because Modbus TCP/IP is universally recognized, it integrates seamlessly into existing Honeywell, Schneider Electric, Siemens, or Rockwell Automation systems without custom driver development.

The Executive’s Perspective

• Drastic Labor Cost Reduction: Eliminates the need for multiple technicians to stand in front of individual load banks with clipboards, reducing field testing labor costs by up to 70%.
• Human Error Elimination: Automated data collection produces clean, unmanipulated, and mathematically accurate compliance reports for end-user sign-off.
• Unmatched System Scalability: Clients can scale their testing infrastructure from a single 500kW load bank to a massive multi-megawatt aggregated fleet simply by plugging into an existing network switch.
• Future-Proof Infrastructure: Equipping units with VCS 2.0 ensures compatibility with upcoming AI-driven facility orchestration platforms and automated microgrid controls.
