Data Centers: Liquid Cooling Systems
Server Cabinet Cooling Solutions
Data center cooling solutions are essential for maintaining reliable performance as computing power and rack densities rise. They remove heat from servers, storage, and networking equipment, keeping temperatures stable and protecting sensitive hardware. Server cabinet cooling manages heat within or near racks, reducing thermal stress while supporting consistent airflow and efficient heat transfer. Common methods include in-row cooling units, rear door heat exchangers, and fan-assisted airflow systems that capture and remove heat at the source.
Advanced techniques like Direct Liquid Cooling (DLC), or Direct-to-Chip cooling, circulate liquid coolant through tubes and cold plates in contact with high-performance electronics such as CPUs and GPUs. By removing heat directly, DLC provides superior thermal control compared to air systems, boosting performance, improving energy efficiency, and lowering operational costs. Integrated sensors and controls monitor temperature, pressure, and flow to prevent hotspots. Properly designed data center cooling solutions extend equipment life and support scalable, high-density computing environments.

Pipes & Accessories
Pipes and pipe accessories are fundamental to data center infrastructure, forming integrated networks that transport cooling water, glycol solutions, and other process fluids required to maintain stable temperatures. Properly sized and routed systems support efficient flow, reduced pressure loss, and reliable operation of chillers, heat exchangers, and cooling towers. Solutions may include high-purity PVDF or PP piping, sanitary stainless steel pipe, fittings, and custom stainless manifolds that provide layout flexibility while supporting smooth direction changes, secure connections, and maintenance access.
Material selection is critical in data center environments, with options such as stainless steel, PVC or CPVC, FRP piping, and sanitary products chosen for chemical compatibility, corrosion resistance, and thermal performance. Accessories including manual valves, compact actuated valves, hangers, supports, and expansion joints, help manage stress and vibration. Together, these piping systems and accessories create a durable framework that supports continuous cooling, energy efficiency, and long term reliability in mission-critical facilities.

Air Handling (Duct Work)
Air handling and ductwork are critical in data centers for maintaining proper airflow and temperature control across server rooms and critical infrastructure. Duct systems distribute cooled or conditioned air from CRAC units, chillers, or AHUs to ensure even cooling, prevent hot spots, and protect sensitive equipment from overheating. Properly designed ductwork optimizes airflow efficiency, reduces energy consumption, and supports stable environmental conditions for high-density computing.
In addition to cooling, duct systems help manage airflow, filtration, and humidity, contributing to overall data center reliability. Materials such as galvanized steel, aluminum, and FRP are chosen for durability and corrosion resistance. Well-planned duct layouts, combined with dampers and diffusers, allow precise airflow management, supporting uptime, operational efficiency, and long-term protection of mission-critical data center assets.

Hose & Hose Assemblies
Tubing and hoses are essential in data centers for connecting equipment and circulating cooling fluids within tight spaces where rigid piping may be impractical. They provide flexibility for routing water, glycol, and other process fluids between pumps, heat exchangers, chillers, and server racks, making installation, maintenance, and system modifications easier. Proper selection ensures reliable performance under pressure, temperature variations, and continuous operation.
Materials such as stainless steel, PVC, and reinforced rubber are chosen for chemical compatibility, durability, and leak resistance. Hoses often feature quick-connect fittings or flexible couplings for rapid replacement or adjustment. By enabling efficient fluid transfer, reducing vibration and stress on rigid components, and supporting modular system designs, tubing and hoses contribute to operational reliability, thermal stability, and uptime in mission-critical data center environments.

In-Rack Manifold
Custom-engineered manifolds enable direct liquid cooling in demanding, mission-critical environments where reliability, safety, and performance are essential. Designed for high-density IT infrastructure, these solutions are built from high-performance polymers that offer excellent chemical resistance, durability, and long service life. The result is a consistent, efficient coolant flow that supports stable rack-level cooling and helps protect critical equipment.
Each manifold is tailored to the specific rack layout and cooling requirements, ensuring uniform coolant distribution to every server tray. This balanced flow reduces the risk of thermal imbalances that can degrade CPU and GPU performance or limit system capacity. Precise flow control, minimal pressure drop, and configurations matched to rack density work together to maximize cooling efficiency, support scalability, and deliver long term system reliability in continuously operating environments.
