VTS Group Data Center Units - Engineered For Mission-Critical Performance

The rapid expansion of digital infrastructure has fundamentally transformed the HVAC landscape. Data centers today demand more than cooling capacity — they require execution certainty, operational reliability, and scalable performance.

VTS Group Data Center solutions are designed precisely for these environments. The portfolio includes CRAH units and Fan Wall Units, engineered to deliver efficient, intelligent, and high-density cooling performance for modern data centers. 

CRAH UNITS – COMPACT PRECISION COOLING

VTS CRAH (Computer Room Air Handler) units provide:

• Nominal airflow: 2,875 – 36,000 CFM (4 900 m³/h - 61 000 m³/h)
• Cooling capacity: 20 – 250 kW
• Dry air operating conditions and chilled water parameters tailored to the project requirements

These compact vertical units deliver maximum cooling capacity with a minimal footprint. Their design allows for:

• High-efficiency airflow with reduced power consumption via EC fan sets
• Optimized chilled water flow using a pressure independent control valve
• Intelligent plug & play controls for precise temperature regulation
• Easy maintenance access without requiring a raised floor

The plug-and-play design simplifies transportation, installation, and commissioning - critical factors in fast-track data center projects. 

FAN WALL UNITS – MODULAR SCALABILITY

For large data halls and hyperscale applications, VTS Group Fan Wall Units provide:

• Nominal airflow: 30,000 – 90,000 CFM (51 000 m³/h - 153 000 m³/h)
• Cooling capacity: 200 – 600 kW
• Dry air operating conditions and chilled water parameters tailored to the project requirements

Key features include:

• Modular design with built-in redundancy
• High cooling capacity with minimal power consumption
• Reliable performance for taller racks and high heat loads

The modular concept enables scalability and redundancy management for up to 16 units, ensuring reliability in mission-critical environments.  

KEY COMPONENTS – ENGINEERED FOR RELIABILITY

At the core of every VTS Data Center unit are carefully selected, high-performance components designed to ensure long-term stability and efficiency:

• High-efficiency EC motors and fan arrays – providing precise airflow control, reduced energy consumption, and redundancy-ready operation.
• Optimized chilled water coils – engineered for high heat transfer efficiency, stable ΔT performance, and compatibility with elevated chilled water temperatures.
• Advanced Plug & Play control system – enabling intelligent temperature regulation, redundancy management, and seamless integration with BMS systems. 

INTELLIGENT CONTROL & ENERGY OPTIMIZATION

Both CRAH and Fan Wall units incorporate an advanced Plug & Play Control System, offering:

• Delta T regulation between supply and return air
• Supply air temperature precision control
• Room or return air control strategies
• Integrated standby and emergency operation modes
• Redundancy management for up to 16 units
• The integrated Energy Valve ensures pressure-independent chilled water flow while enabling energy measurement and eliminating the need for manual hydraulic balancing.

Advanced Sensors Provide:

• Real-time fan power consumption monitoring
• Calculated EER/AER values
• Continuous airflow measurement
• Filter contamination detection for proactive maintenance

This intelligent ecosystem supports stable operation, performance transparency, and energy optimization — key requirements in high-performance data center facilities.

LOGISTICS OPTIMIZED FOR SCALE

Recognizing the importance of transport efficiency in large deployments, VTS units are engineered for container and truck logistics:

• CRAH units: optimized packaging with 10–12 units per truck or container
• Delivered in two transport packages (heat exchanger cube + fan cube)
• Fan Wall cubes optimized for standard container transport
• Special base frame enabling safe forklift handling without crane lifting eyes

This approach minimizes logistics costs while accelerating on-site deployment.

BUILT FOR TODAY’S DATA CENTER INFRASTRUCTURE

VTS Data Center units combine:

• Modular scalability
• Plug&Play controls
• Optimized chilled water management
• Logistics efficiency

The result is a practical, deployable cooling platform designed for environments where uptime, precision, and operational certainty are non-negotiable.
