The rise of AI and high-density computing has pushed data centre cooling past the limits of air. Liquid cooling — moving heat away from chips and racks with coolant instead of air — is now mainstream, and it needs purpose-built hoses, couplings and pumps. This guide explains the key components and how to choose them. Twin Hydraulics Engineering supplies Gates and HANSA-FLEX liquid-cooling products in Malaysia.
Why liquid cooling?
Liquid carries far more heat than air for the same volume, so it can cool densely packed servers that air simply cannot. Direct-to-chip cold plates and rack manifolds bring coolant close to the heat source, keeping equipment within safe temperatures while saving energy and floor space.
The core components
Cooling hoses
Cooling hoses must be flame-resistant, low-contamination and compatible with the coolant. Gates Data Master hoses use zinc-free, peroxide-cured EPDM and meet UL94 V-0, with MegaFlex versions for high-flow source lines and Eco versions in halogen-free materials. Colour coding (blue for supply, red for return) keeps installations organised. See our cooling hoses.
Quick-disconnect couplings
Couplings let technicians connect and disconnect without spilling coolant or shutting down a rack. OCP-compliant Universal Quick Disconnect (UQD) couplings — from Gates and HANSA-FLEX — offer dry-break disconnection under pressure for zero-downtime maintenance. Browse couplings.
Coolant pumps
Pumps circulate coolant through the loop. Gates data-centre pumps span low-power units up to ultra-high-power 2.5–11 kW pumps delivering around 1500 L/min, with a high power-to-volume ratio for tight spaces. See coolant pumps.
Choosing the right setup
Match hose size and pressure rating to your flow, select couplings that follow the OCP standard for cross-compatibility, and size the pump to the total loop flow and pressure drop. Accessories such as valves, fittings and clamps complete a reliable circuit — see accessories.
