Precision cooling (CRAC/CRAH) manufacturers and suppliers in Singapore

A UPS and precision-cooling specialist for mission-critical loads. On power it offers Kohler decentralised parallel architecture (DPA) systems from 10 to 500 kVA with hot-swap modules, up to 96% online and 99% eco-mode efficiency, plus maintenance and consultancy; on cooling it runs three CRAC/CRAH lines (Smart Cooling, Smart In-Row, Smart Nano) plus liquid-cooling infrastructure — CDUs, rear-door heat exchangers, fan-wall units and direct-to-chip components — with CFD analysis and leak and environmental monitoring.

A critical-power and precision-cooling house for data centres, server rooms and telecom facilities. On power it designs and sizes N+1 UPS systems with load assessment, battery-monitoring, harmonic active filters and heat-load and CFD testing of the power-and-cooling envelope; on cooling it supplies floor-standing, ceiling-mounted (CCMU) and fan-array room units plus in-row and in-rack direct cooling holding temperature within about 1 degree C, with cooling-load calculation, rack-density review and airflow assessment.

A Singapore deep-tech liquid-cooling firm using proprietary oblique-fin cold-plate technology: custom cold plates, two-phase cooling, a Liquid-Cooled Compute Pod (LCCP) and integrated liquid-cooled racks with in-house CFD, claiming 25-50% energy savings and PUE below 1.06. Its liquid cooling has been deployed at Digital Realty's SIN11 data centre in Singapore.

One of Singapore's most established M&E and MEICA (multi-discipline systems-integration) groups, delivering integrated energy solutions across cooling, solar, cogeneration and heat recovery plus integrated facilities management, and holding the BCA ME05 L6 electrical register grade. Sectors served: data centres, semiconductor, pharma, F&B and chemicals manufacturing, infrastructure (airports, ports, water and waste-to-energy) and marine. HQ at Tuas View Crescent.

Holds unrestricted BCA L6 across ME01 (ACMV), ME05 (Electrical) and ME15 (Integrated Building Services). Builds and maintains M&E for data centres (Tier redundancy, liquid cooling), advanced manufacturing and semiconductors, cleanrooms and pharma labs, with LV/HV maintenance, transformer and HT switchgear testing and AI-driven chiller and energy optimisation.

A Singapore M&E contractor whose mechanical scope spans ACMV, chillers, mechanical ventilation, ducting, plumbing and sanitary and fire protection, plus explosion-proof air-conditioning and smoke control; designs to Green Mark. Sectors: defence, healthcare, transport, education, industrial and retail.

An ACMV and mechanical-ventilation ductwork specialist installing MV duct systems for car parks, toilets and basements of large commercial and retail buildings.

Registered ME01 (ACMV) L5, ME15 L5, ME05 L3 and ME06 L2, and a BCA GB01 Licensed Builder. Designs, installs, tests and commissions central chilled-water, DX and VRV systems with fire protection, plumbing and sanitary, and BMS; projects include Fairmont Singapore.

Registered at top grade ME15 L6 and ME01 (ACMV) L6, plus ME05 (Electrical) L5. Installs split, VRV, AHU and PAHU units, ductwork and mechanical ventilation, and both air-cooled and water-cooled chilled-water systems with BMS and smart-building controls. Among the top-graded dedicated ACMV houses in the set.

An Asia-wide mission-critical infrastructure integrator with Singapore operations pairing power protection with advanced cooling: immersion cooling, liquid-cooling systems and thermal management for HPC and data centres, plus modular and prefabricated MEP, an in-house workshop and installation, testing and commissioning.

Registered ME01 (ACMV) L6 and ME15 L5: ACMV installation, ductwork fabrication, duct cleaning and maintenance across residential, commercial and industrial.

A Singapore-headquartered immersion-cooling technology provider (a subsidiary of Firmus Technologies) and NVIDIA partner; its HyperCube system immerses NVIDIA-based servers in synthetic fluid with a claimed roughly 50% electricity reduction versus air.
