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.

Key Features

Multi-pass microchannel coils
Variable speed EC fans
Variable flow control valve for glycol systems
Programmable Logic Controller (PLC)
Optional factory-installed master control panel (MCP)
BACnet/IP and Modbus compatibility
