Vertiv CoolLoop RDHx Rear-Door Heat Exchangers

High-Density Cooling for AI-Ready Server Racks and Data Centers

The Vertiv™ CoolLoop RDHx Rear-Door Heat Exchanger delivers efficient chilled-water cooling for high-density IT equipment, AI computing infrastructure, enterprise server rooms, and modern data centers.

Designed to remove heat directly at the server rack, Vertiv CoolLoop RDHx helps reduce hot spots, improve thermal management, and minimize the floor space required for traditional cooling equipment.

Available in active and passive configurations, CoolLoop RDHx supports cooling applications ranging from approximately 5 kW to 85 kW per rack, depending on the selected model and operating conditions.

Mainline Computer Products, Inc. provides Vertiv cooling and critical infrastructure solutions to businesses, government agencies, educational institutions, and data center operators.

How Vertiv CoolLoop RDHx Works

The rear-door heat exchanger replaces or integrates with the rear door of a compatible IT rack. Hot exhaust air from the servers passes through a chilled-water heat exchanger, where heat is transferred from the air into the facility's water-cooling circuit.

The cooled air is then returned to the surrounding environment, helping maintain more consistent room temperatures and reducing the cooling burden on the facility.

This rack-level cooling approach is particularly valuable for high-density IT deployments where conventional room air conditioning may be insufficient or inefficient.

Features and Benefits

• High-density cooling: Supports demanding IT heat loads, including AI and high-performance computing applications.

• Active and passive configurations: Select fan-assisted cooling or passive operation using existing server airflow.

• Energy-efficient operation: Removes heat at the rack, potentially reducing the burden on conventional room cooling systems.

• Space-saving installation: Rear-door mounting preserves valuable data center floor space.

• Scalable cooling: Modular configurations accommodate changing equipment loads and infrastructure requirements.

• Chilled-water integration: Connects with compatible facility chilled-water infrastructure.

• Hybrid liquid cooling: Complements direct-to-chip liquid cooling by removing remaining air-side heat.

• Monitoring and control: Select active configurations support Vertiv Liebert iCOM monitoring and controls.

• Reduced maintenance requirements: Designed with limited moving parts for reliable operation.
