Product Overview
The Air-Cooled CRAC Unit is a precision environmental control equipment specifically designed for data centers, server rooms, and mission-critical environments. CRAC (Computer Room Air Conditioner) is a specialized air conditioning unit for electronic equipment rooms, designed to maintain temperature, humidity, air cleanliness, and air circulation to support year-round cooling requirements. Unlike conventional comfort air conditioners, CRAC units are primarily designed to reduce room temperature (featuring high sensible heat ratio), typically achieving a sensible heat ratio of over 90%.
The Air-Cooled CRAC Unit employs an air-cooled direct expansion (DX) refrigeration cycle, with an outdoor air-cooled condenser that rejects heat directly to the atmosphere via refrigerant. The system requires no cooling towers or chilled water piping, offering easy installation and independent system operation - making it particularly suitable for water-scarce regions or facilities where cooling water systems are not feasible. The units utilize R410A or R454B environmentally friendly refrigerants, delivering temperature control accuracy of ±1℃ and humidity control accuracy of ±3% to ±5%.
Applications

Key Features
Precision Environmental Control
Equipped with high-precision sensors and intelligent controllers for real-time monitoring and regulation of temperature and humidity, maintaining environmental parameters within the optimal range for equipment operation. Supports integrated multi-function control including heating, humidification, dehumidification, and air filtration.
High Sensible Heat Ratio Design
Optimized for high-density data center environments with a sensible heat ratio ≥0.9, dedicating the majority of cooling capacity to directly reducing air temperature while avoiding energy waste from excessive dehumidification.
High Reliability
Built with rigorously tested, high-quality components, engineered for 24/7 continuous operation with long service life and low maintenance requirements. Critical components support redundant configuration to ensure system availability remains intact in the event of a single point of failure.
Smart Control & Management
Equipped with true-color touchscreen displays, multi-level password access control, and self-diagnostic system functions. Comprehensive monitoring and display of key parameters including power supply voltage, frequency, cooling capacity, airflow, and temperature/humidity trends. Supports group control of multiple units with advanced features including scheduled rotation, fault-based rotation, cascading, and demand synchronization. Compatible with Building Management Systems (BMS), with communication protocols flexibly configurable based on project requirements.
Flexible Deployment
Supports multiple airflow configurations including upflow and downflow to accommodate various room layouts such as raised-floor underfloor supply and ceiling return air. Outdoor condensers can be selected based on project needs, supporting installation in compact spaces.
