UPS systems manufacturers and suppliers in Singapore

A Singapore Master Systems Integrator managing design, testing and commissioning of smart-building networks, unifying BMS/IBMS, M&E and ELV (security and access) into a single-pane platform with cybersecurity and vendor-neutral, open integration.

A diesel-generator supplier packaging open-frame, silent, trailer-mobile and containerised sets from 20 to 1,100 kVA with installation, maintenance and load testing; states containerised heavy-duty units are used in data centres.

Supplies and installs LV and MV busduct, primary power-distribution equipment and cabling infrastructure, and supplies HV switchgear; also cable containment and EV-charging works.

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.

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.

Professional Engineers and Licensed Electrical Workers specialising in HV and LV testing and commissioning: switchgear, protection-relay testing, cable diagnostics, transformer and earthing verification.

A BCA ME05 L6 specialist electrical contractor covering design, installation, testing and commissioning and maintenance to SS/IEC standards with EMA licensing, serving the data-centre sector.

Part of the LKH group; supplies and installs busway and busduct from LV to HV up to 128 kV (Schneider sandwich busway, Tecobar cast-resin MV to 22 kV, Duresca and MGC HV busbar) with in-house design, testing and commissioning, and lists data-centre projects. A value-added distributor of power-distribution products, cabling systems and EMC and shielded-room solutions.

An LV switchboard and switchgear manufacturer: modular main switchboards, distribution boards, ATS and static-switch panels, and data-centre PDU/UPS components, built to IEC 60439-1 and SS 293.

Operates a switchgear plant in Singapore and is on the BCA ME05 L6 register. A subsidiary of Japan's Meidensha.

A standby diesel-generator packager and integrator handling installation, maintenance, load-bank testing and temporary power from 45 to 3,000 kVA on Cummins, Volvo Penta, Perkins and MTU engines; certifies to SS 535 (NEA-approved, ISO 45001) and cites a data-centre installation.

The urban and smart-infrastructure line of ST Engineering. Its Cloud & Data Centre Solutions entity holds BCA ME05 L6 for large power and electrical scopes in the data-centre segment, and its AGIL Smart Energy Building line delivers integrated building management, energy-decarbonisation dashboards and integrated security management (AGIL Secure) for smart-estate and campus deployments.

An SGX-listed total power-distribution solutions provider manufacturing LV/MV and instrumentation cables and supplying power-distribution products across industrial, commercial and marine, with switchboard arms in the group.

Carries one of the fullest L6 stacks on the BCA ME register — ME01 (ACMV) L6, ME05 (Electrical) L6, ME11 (Mechanical Engineering) L6 and ME15 (Integrated Building Services) L6 — as a specialist in integrated M&E installation.

A critical-power and UPS provider delivering single- and three-phase UPS for data centres and enterprises with 24x7 onsite support, preventive maintenance, and lithium-ion and lead-acid battery management.
