Features

Introduction:

 

CRA Row-Based Air-Cooled Aircon is installed in close proximity to heat sources, minimizing the length of the cold airflow path and accurately handling the sensible heat generated by servers.

 

Application:

 

Small-to-medium-sized Data Centers

Modular Data Centers

Cabinet Row Cooling (or heat) Channel Retrofitting

Medium-to-high heat-density Communication Equipment

Computer Rooms

 

Features:

 

The key components are selected from well-known brands.

A fully EC variable frequency design, automatically adjusting cooling and airflow output.

The humidification component has zero power consumption and is energy-efficient.

 The "full cabinet-style straight or U-shaped" evaporator has a large area and low air resistance.

 The high-return air temperature design significantly improves energy efficiency.

Three operation modes automatically switch and adjust in real-time.

 The pump cabinet system is designed in series, highly integrated, and more energy-efficient.

 The pump cabinet is integrated on the outside, eliminating the need for separate space.

 It integrates efficient energy-saving algorithms and supports group control, rotation, and cascading.
