Rack-Mounted Liquid-Cooled Load Bank for Data Centre
Purpose-built for rack-level CDU commissioning and liquid-cooled data centre testing.
What rack-mounted liquid-cooled load bank does
19-inch standard rack-mount form factor — slots directly into a 42U server rack. Replaces liquid-cooled servers for commissioning purposes. Applies a pure resistive IT load on the electrical side while transferring heat directly into the CDU liquid circuit on the cooling side.
Rack-mounted liquid-cooled load bank = Resistive heating + Direct liquid cooling.
Simulates server power consumption for electrical testing, and precisely transfers heat into the liquid cooling loop for rack-level cooling testing.
One unit completes power testing + CDU validation simultaneously.
Rack-mounted liquid-cooled load bank & CDU system integration
Slots into standard 19" server rack — replaces servers for commissioning.
Standard rack-mount form factor fits directly into 42U server cabinets. No special installation required — connects to existing CDU liquid return circuit and PDU.Connects directly to CDU return circuit for thermal load testing.
Factory-configured CDU fittings match your specific CDU model. Applies thermal load to the CDU return line to validate capacity, ΔT, flow rate, and alarm response.Enables centralised multi-unit management without complex wiring.
TCP/IP for remote multi-unit management over network. PC cluster control software available for synchronised loading across multiple rack positions.Guarantees reliable on-site operation even without network access.
On-site operation via local PLC controller and touchscreen HMI panel. Full manual control is available, with no network dependency during commissioning and testing.Rack-mounted liquid-cooled load bank manufacturer — Batterlution

CDU acceptance testing
Validate CDU performance before server deployment. Slots into the server rack, connects to CDU liquid return circuit, applies thermal load at real liquid-cooled server density.
PDU / UPS / generator load testing
Validate electrical distribution before go-live. Connects to the PDU, applies rated resistive load, validates electrical distribution and backup systems.
CDU transient performance testing
Simulate dynamic thermal profiles characteristic of real IT loads. Tests CDU control response under dynamic conditions and cooling chain transient bottlenecks.
Full-load endurance testing
Validate long-term CDU and cooling chain performance. Maintains high-density thermal load continuously over extended run periods.
Rack-level power density testing
Test cabinet power capacity at real server heat density. 4–6× higher power density than air-cooled load banks in the same U-space.
Partial load transfer testing
Validate N+1 and 2N cooling redundancy. Monitor switchover performance and thermal margin under partial load conditions.

Common Question
What does this unit replace in the commissioning sequence?
It replaces liquid-cooled servers at the rack level for CDU acceptance testing, and also performs the same PDU/UPS/generator load testing as a standard rack air-cooled load bank. In a liquid-cooled data centre, this unit replaces two separate pieces of equipment.
How does it connect to the CDU?
The unit connects to the CDU liquid return circuit via fittings configured to your specific CDU model at the factory. Specify the CDU make and model at enquiry — the connection configuration is confirmed before order and built into the unit. No adapters required on site.
Does it need active communication with the CDU to operate?
No. Standard commissioning does not require active communication with the CDU — the load bank generates thermal load and the CDU responds automatically. The optional Modbus CDU link is used when engineers require coordinated load-step testing or precision regulation accuracy measurement.
What power range does each unit support?
Standard configuration supports 30–50 kW per unit. The 6–50 kW range covers most rack-level CDU test requirements. Multi-unit parallel is supported for higher total thermal load. Maximum total power is confirmed at quotation.
How does this compare to the floor-standing liquid-cooled load bank?
The rack-mount unit is designed for rack-level CDU commissioning — it replaces servers inside the data hall. The floor-standing liquid cooled load bank is designed for full electrical plus cooling chain commissioning — larger thermal loads, outdoor or plant room installation, simultaneous power system and chiller testing.
What certifications does the unit carry?
Units are designed to IEC 60947-1 and IEC 60947-4-1. CE certification is available as standard. UL certification is available on request. ISO 9001 quality system applies to all units. FAT report included with every shipment.
What is the lead time?
Lead time will be confirmed during the quotation process based on your CDU specification and customisation requirements. Please contact us with your specification to receive an accurate delivery timeline.
How do I request a quotation?
Send the CDU model, target power, rack specification, and communication protocol requirement. Batterlution confirms configuration and issues a formal quotation within 48 hours. No obligation, and custom configurations are standard practice.
