Room-Level PAC 30-50kw DTCRA Series

DTCRA / DTCRC Series Precision Air Conditioner Air-cooled and chilled-water precision air conditioner for large data centers.

The DTCRA series includes air-cooled DTCRA and chilled-water DTCRC models. Air-cooled units cover 25–100 kW, while chilled-water units cover 30–200 kW. Modular combination enables flexible capacity matching, with down-supply and top-supply air modes available. It is applied in large data centers, central data centers, substations, and heavy-load equipment rooms. It supports customization for heating, humidification, and multiple supply/return air modes, and features large air volume, small enthalpy difference, high sensible heat ratio, EC fans, electronic expansion valves, R410a, and full alarm protection (power, water leakage, T&H over-limit, component protection). A 7-inch color touch screen, RS485/Modbus, group control up to 32 units, and remote monitoring are provided as standard.

Product Feature

Modular Flexible Capacity Matching

The modular unit design allows multiple modules to be freely combined for customized cooling output. Down-supply and top-supply air modes adapt to different data center air duct layouts. Air-cooled and chilled-water versions are available for different site resource conditions.

High-Performance Core Components

High-reliability scroll compressors provide low-noise and low-vibration operation.
Optional aviation-composite corrosion-resistant EC fans improve efficiency.
Electronic expansion valves deliver precise refrigerant flow control. PTC heating and large-capacity electrode humidification ensure stable temperature and humidity adjustment.

Powerful Group-Control Intelligence

A 7-inch high-precision color touch HMI supports group control of up to 32 units for centralized scheduling. A complete alarm diagnosis system is provided. Local display and remote monitoring linkage facilitate unified O&M management in large data centers.
