L1000 Liquid Cooling Distribution Unit

The ThermalWorks L1000 CDU provides precise flow and temperature control for both liquid and air-cooled deployments. With a high delta-T design and a highly efficient heat exchanger, it ensures full separation of the primary and secondary loops. The L1000 eliminates the need for tempering valves, reduces pump energy, and offers the fastest system recovery after a power event—making it ideal for mission-critical environments.

KEY FEATURES
  • Dual power feeds
  • Three built-in pumps for secondary fluid
  • Programmable Logic Controller (PLC) provides integrated controls
  • Brazed Plate Heat Exchanger enables high efficiency heat transfer (2x more efficient than competing CDUs)
  • Integrated fluid filtration for filter replacement
  • Primary and secondary fluid piping
  • Flow monitoring for primary and secondary circuits
KEY FEATURES
  • Multi-pass microchannel coils
  • Variable speed fan features an electronically commutated motor (ECM) to support high air flow levels while minimizing energy consumption.
  • Radial and axial air flow options.
  • Variable flow control valve for glycol fluid.
  • Programmable logic control (PLC) panel
  • Optional air diffuser precisely directs airflow to ensure even mixing and avoid hotspots.

Reliable, Smart, and Efficient Cooling Infrastructure

Redundant Power
& Pumps

Dual power feeds eliminate the need for external ATS, while three hot-swappable pumps ensure uninterrupted operation.
Smart Integrated Controls

Each CDU has a PLC with a 7” display, supporting BACNet, Modbus, and automated setpoint adjustments.
High-Efficiency Heat Transfer

A variable flow control valve scales cooling capacity without manual rebalancing, maintaining system stability.
Durable, Corrosion-Resistant Piping

Non-corrosive Aquatherm SDR11 primary piping and 316-grade stainless steel secondary piping ensure long-term reliability.
Advanced Flow &
Remote Monitoring

Flow monitoring is included for both circuits, with optional remote central monitoring available.
