PRASA’s Cooling Technology Solutions
Pioneering Efficiency with RDHx, DCLC and LIC Cooling Solutions
SUSTAINABLE DC COOLING SOLUTION
RDHX (Rear Door Heat Exchanger Solutions)
Rear Door Heat Exchangers (RDHx), is the most effective air cooling technology in high-density environments. It can cool up to 74 KW of heat load inside a single 52U rack.
RDHx systems work by removing heat from the exhaust air of IT equipment through a heat exchanger mounted on the back of the server rack. In this process, chilled water (the “liquid” component) absorbs heat from the exhaust air, cooling it before recirculating it back into the data center.
KEY FACTORS TO CONSIDER INCLUDE:
- HEAT LOAD:
RDHx is most effective in high-density environments with substantial heat loads, providing efficient cooling directly at the equipment level.
- SERVER DESIGN:
RDHx suits any of the shelf air-cooled servers with the latest CPU/GPU processors.
PRASA has successfully implemented over 4-5 MW of RDHx cooling capacity, showcasing its commitment to innovative, efficient data center cooling solutions. With Power Usage Effectiveness (PUE) values between 1.35 – 1.4, PRASA’s RDHx deployments have demonstrated significant energy savings and optimized performance for data centers.

SUSTAINABLE DC COOLING SOLUTION
DCLC (Direct Contact Liquid Cooling)
Direct Contact Liquid Cooling (DCLC) represents a leap in efficiency and performance for high-density data centers. Also known as Liquid-to-Liquid Cooling, DCLC operates by channeling coolant directly over server components, such as CPUs, GPUs, and memory, effectively managing temperatures while supporting heat loads up to 80kW per rack.
PRASA has successfully implemented this technology for nearly 2 MW of IT load, operating efficiently for several years.
WHY DCLC?
DCLC minimizes environmental impact and reduces operational costs. Heat is transferred away from critical components and dissipated through an integrated heat exchanger, achieving Power Usage effectiveness (PUE) ratings between 1.2 to 1.3. DCLC systems are optimal for scalable deployments, providing unmatched thermal
control even in demanding climates and environments.
DCLC System Types:
SINGLE-PHASE DCLC:
Single-phase Direct Contact Liquid Cooling (DCLC) utilizes a two-liquid system to manage heat. The primary liquid in this setup is warm water, which absorbs heat directly from the server components. The secondary liquid is a mixture of water and glycol, which acts as a coolant to transfer the absorbed heat away from the IT hardware.
TWO-PHASE DCLC:
Two-phase Direct Contact Liquid Cooling (DCLC) is an advanced thermal management system that uses two distinct liquids to enhance cooling efficiency. The primary liquid in this system is warm water, which absorbs heat from the IT components. The secondary liquid is a synthetic dielectric liquid, which is engineered to facilitate heat absorption and ensure a more efficient phase-change process.
Types of
Coolant Distribution Units (CDU):
Coolant Distribution Units (CDUs) are critical in maintaining optimal temperature control within data centers, ensuring that servers and IT equipment operate at peak efficiency. Various types of CDUs are available to meet the specific cooling needs and configurations of data centers. These include In-Row or Sidecar, In-Rack, Liquid-to-Air (L2A), and Liquid-to-Liquid (L2L) CDUs, each designed with unique features and tailored to specific cooling requirements.
Liquid to Air (L2A) CDUs:
Liquid-to-Air (L2A) Coolant Distribution Units (CDUs) e iciently transfer heat from a liquid coolant, such as
water or a water-glycol mixture, to the surrounding air.
Liquid to Liquid (L2L) CDUs:
Liquid-to-liquid (L2L) Coolant Distribution Units (CDUs) transfer heat between two distinct liquid cooling loops, with facility water used to extract heat from the equipment in server racks and rows.

Liquid Cooling for AI Workloads
In today’s dynamic technological landscape, artificial intelligence (AI) is catalyzing an unprecedented demand for high-performance computing (HPC) solutions. The rapid adoption of AI applications, powered by advanced machine learning (ML) and deep learning algorithms necessitates significant computational resources to process vast datasets and execute complex operations. This computational intensity, while critical for innovation, generates substantial heat within data center environments, posing challenges to traditional cooling systems.
Conventional air-cooled systems often fall short of addressing the high heat density produced by AI-driven
workloads. As a result, forward-thinking organizations are turning to innovative liquid cooling technologies to
meet these demands effectively. Liquid cooling solutions utilize advanced methods such as submerging
hardware components in dielectric fluids or delivering targeted coolants directly to heat-intensive components. These approaches not only enhance heat dissipation but also improve overall system performance, energy efficiency, and reliability.
