A125 / A145  Precision Air Handler

The ThermalWorks A125/A145 Precision Air Handler provides high capacity air cooling with high delta-T and energy efficient operation for data centers. Each Air Handler features custom ultra-efficient micro-channel coils, an efficient ECM fan, variable flow valves and onboard programmable controller that enables direct control of any unit in an array.

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

Adaptive Cooling with Maximum Efficiency

Efficient Heat Transfer for Data Halls
Multi-pass microchannel coils maximize heat transfer from air to a glycol-based cooling loop, ensuring optimal performance.
Energy-Saving Variable Speed Fan
An electronically commutated motor (ECM) adjusts airflow levels for efficiency, with radial and axial options to suit diverse data hall configurations.
Self-Balancing Glycol Flow Control
A variable flow control valve scales cooling capacity without manual rebalancing, maintaining system stability.
Smart Adaptive Controls
A programmable logic control (PLC) panel dynamically adjusts fan speed and flow valve position for real-time optimization.
Targeted Airflow to Prevent Hotspots
An optional air diffuser ensures even air distribution, eliminating temperature inconsistencies.
Reliable Dual Power Sources
Redundant A and B power inputs (3-phase 400/460 VAC, 50/60 Hz) ensure continuous, fail-safe operation.
