Solutions

The Full Mechanical & Electrical Scope.

Engineered for environments where downtime is not an option — drawing on a network of specialist capabilities that mission-critical facilities depend on.

01 — PowerPower & Energy
Power Aftersales Service

Power & Energy

The backbone of any critical facility.

Primary and standby power engineered for continuous operation, with the monitoring and maintenance to keep it reliable across its full life.

  • Standby & Prime Generators

    Yuchai diesel & gas gensets; containerized and site-built configurations, sized to facility load.

  • Solar PV Systems

    Rooftop and ground-mount design and installation, delivered with Powerbrain; 50+ MWp installed.

  • Fuel Monitoring Systems

    Real-time fuel level, consumption, and theft detection, powered by Ramus instrumentation.

  • Engine Maintenance & Overhaul

    Authorized spare parts and overhaul for IHI / Niigata land and marine engines through Ramoco.

Aftersales Service — IHI / Niigata Engines

Reliability does not end at commissioning. Engine systems are backed by a structured aftersales program delivered with the manufacturer.

  • 8 certified Indonesian engineers trained in Niigata Power Systems, Japan.
  • 20+ years combined experience in maintenance, overhaul, and troubleshooting — marine and land-use engines.
  • Dedicated Niigata engineers from the Customer Support Center for the Indonesian region — troubleshooting, supervision, and overhaul.
  • Annual courtesy visits to each customer in Indonesia by the principal.
  • Open communication channel between manufacturer and customer for any clarification or troubleshooting.
  • Case-by-case field reports — photo details, findings, and manufacturer recommendations.
02 — CoolingPrecision Cooling & HVAC

Precision Cooling & HVAC

Cooling that performs under load.

Cooling is where most of a facility's electricity goes. Getting it wrong costs money every month.

Air Cooling

  • Chiller Plants & VRF Systems

    Midea, Broad, and Hisense for high-density and commercial cooling loads.

  • Chiller Optimization & Retrofit

    Plant automation, VSD retrofits, pump rewinding. On one 3×550 TR plant, we took efficiency from 1.10 to 0.77 kW/TR.

  • Cooling-as-a-Service

    The client pays nothing upfront. Powerbrain finances, installs, and operates the cooling system; performance is contractually guaranteed and backed by an insurance-grade performance bond, measured against the IPMVP standard.

Liquid Cooling (Data Center & High-Density Compute)

  • Maglev Active CDU

    Midea's integrated maglev chiller and CDU in a single chassis. Saves over 50% floor space. PUE below 1.2.

  • Industrial-Grade CDU

    Up to 2,600 kW cooling capacity, built for 24/7 continuous operation across hyperscale rack environments.

  • Liquid-Cooling Terminals

    Direct chip and processor-level cooling for extreme thermal loads at the rack.

  • Air-Fluid Synergy

    Midea's hybrid architecture coordinating precision air conditioning with rack-level liquid cooling.

03 — MonitoringMonitoring & Security

Monitoring & Security

Total visibility over critical infrastructure.

Critical infrastructure requires constant visibility. We integrate instrumentation and surveillance into a unified operational view.

  • Flow Metering

    Emerson and Endress+Hauser meters for chilled-water and process monitoring, integrated by Ramus.

  • Surveillance Systems

    KINGSAT surveillance solutions through Ramus.

  • Smart Control & Monitoring

    Centralized monitoring of power, cooling, and fuel systems.
