Power Generation Solutions by PT Elbrus Power Sistem

Authorized Distributor for Rehlko (formerly Kohler) Industrial Generator Sets in Indonesia

Reliable power is not a convenience — it is the foundation that keeps hospitals running, data centers online, factories producing, and critical infrastructure functioning without interruption. As the official authorized distributor for Rehlko (formerly Kohler) Industrial Generator Sets in Indonesia, PT Elbrus Power Sistem brings a globally trusted power generation brand to the local market, backed by certified engineering expertise, genuine components, and responsive after-sales support that international manufacturers alone cannot provide.

Since our establishment in March 2021 — when we began as the MTU Rolls-Royce System Integrator for the Indonesian market — we have built our reputation on precision, accountability, and long-term partnership. In 2024, that reputation led to our appointment as Rehlko’s authorized distributor, further strengthening our position as a dependable power solutions provider for organizations that cannot afford downtime.

Why Choose Elbrus as Your Power Generation Partner

Choosing a generator set supplier is not simply a matter of comparing specifications on a datasheet. It is a decision about who will stand behind that equipment for the next ten, fifteen, or twenty years of its operating life. Many buyers in Indonesia have experienced the frustration of purchasing generator sets through unauthorized channels — only to discover, months or years later, that genuine spare parts are difficult to source, warranty support is unclear, and technical documentation is incomplete or outdated.

PT Elbrus Power Sistem eliminates that risk. As an authorized distributor, every unit we supply comes with a verifiable chain of accountability back to the manufacturer, full access to genuine Rehlko components, and a local technical team that understands both the equipment and the operating conditions unique to Indonesia — from tropical humidity and voltage fluctuation to the logistical realities of remote industrial sites. Our engineering team is trained directly on Rehlko systems, meaning that installation, commissioning, and troubleshooting are handled by people who know the platform inside and out, not by generalist contractors learning on the job.

We are also certified under ISO 9001 (Quality Management), ISO 14001 (Environmental Management), and ISO 45001 (Occupational Health and Safety) — an assurance that our processes, from procurement through project delivery, meet internationally recognized standards. For procurement teams and project managers who must justify vendor selection to their own stakeholders, this certification provides the documentation and accountability that unauthorized resellers simply cannot offer.

Our Generator Set Range

Rehlko generator sets are engineered across a comprehensive range of capacities, allowing PT Elbrus Power Sistem to match the correct solution to virtually any application — from a small commercial building to a hyperscale data center. Below is an overview of the three primary capacity tiers we supply, install, and support across Indonesia.

Small Scale: 20 – 500 kVA

This tier is designed for offices, residential complexes, retail outlets, restaurants, and small-to-medium commercial facilities that require dependable backup power during utility outages. These units are compact, relatively quick to install, and cost-effective for facilities where power demand is moderate but continuity is still important — such as maintaining refrigeration, security systems, lighting, and essential business operations during a blackout.

Medium Scale: 800 – 2,500 kVA

Manufacturing plants, hospitals, hotels, shopping centers, and larger commercial developments typically fall into this range. At this capacity, generator sets are frequently configured not just for emergency backup, but for prime power applications — supporting continuous or semi-continuous operations where grid power is unreliable or unavailable. Facilities in this category often require more sophisticated load management, synchronization with existing electrical systems, and more rigorous commissioning procedures, all of which our engineering team is equipped to handle from design through handover.

Big Scale: 2,800 – 4,500 kVA

At the top of the range, these generator sets are built for Tier 3 and Tier 4 data centers, heavy industrial facilities, mining operations, and critical national infrastructure — environments where even a few seconds of downtime can result in significant financial loss or safety risk. Projects at this scale typically involve multiple units configured in parallel for redundancy, along with advanced control and monitoring systems. PT Elbrus Power Sistem has direct project experience at this capacity tier, including the successful supply and installation of two 3,750 kVA Rehlko diesel generator sets for a Tier 3 uptime data center project in Bali.

What We Provide: Beyond the Generator Set Itself

A generator set is only as reliable as the ecosystem supporting it — the controllers that manage it, the documentation that guides its maintenance, and the team that installs and services it. PT Elbrus Power Sistem delivers a complete package around every unit we supply.

Industrial Generator Sets: We supply backup, prime, and continuous power generator sets for industrial applications, available in diesel, natural gas, and LP gas configurations. This flexibility allows clients to select the fuel type best suited to their operational environment, budget, and sustainability goals, without compromising on reliability or performance.

Genuine Controllers and Monitoring Systems: Every generator set we deliver is equipped with Rehlko’s advanced control systems — the component that continuously monitors voltage, frequency, temperature, and operating conditions to ensure the unit performs reliably and shuts down safely if a fault is detected. These controllers are also what enable remote monitoring, allowing facility managers to track generator health without needing to be physically on-site.

Turnkey Project Delivery: From initial site assessment and load calculation, through procurement, installation, and commissioning, our team manages the entire project lifecycle. This turnkey approach is backed by Rehlko’s global manufacturing network of over 800 distributors and 10,000 dealers worldwide, ensuring that even large or complex projects have access to the parts, technical resources, and engineering support required for on-time delivery.

Genuine Spare Parts and Maintenance: Long-term reliability depends on using genuine components and following a disciplined maintenance schedule. We stock and supply authentic Rehlko spare parts and provide scheduled preventive maintenance, on-site servicing, and rapid technical response — minimizing the risk of extended downtime due to counterfeit parts or delayed service.

Technical Documentation and Consultation: We provide complete, up-to-date product literature, specifications, and technical documentation to support procurement decisions, engineering reviews, and regulatory compliance requirements — an essential resource for project managers who need to present clear technical justification to stakeholders or government bodies.

Industries We Serve

Over the course of our project history, PT Elbrus Power Sistem has delivered generator set solutions across a diverse range of sectors in Indonesia, each with its own operational demands and risk tolerances.

• Data Centers — supporting Tier 3 uptime requirements with high-capacity diesel generator sets configured for redundancy and rapid failover, where even brief interruptions can affect thousands of connected users and services.
• Government and Defense — including generator set and UPS installation projects for state-owned enterprises and government institutions, where procurement accountability and certified equipment are non-negotiable requirements.
• Manufacturing and Industrial Facilities — providing reliable prime and standby power for continuous production lines, where unplanned downtime translates directly into lost output and revenue.
• Aviation and Transportation — supporting critical infrastructure and communication systems for organizations including international airline operators, where system reliability intersects directly with passenger safety and operational continuity.
• Mining and Energy — delivering rugged, dependable power solutions for remote and demanding operational environments where grid access is limited or nonexistent.
• Telecommunications — supporting IP communications, network infrastructure, and data switching systems that require stable, uninterrupted power to maintain connectivity.

Choosing the Right Fuel Type

Rehlko generator sets are available in three primary fuel configurations, each suited to different operational contexts:

Diesel remains the most widely used option for industrial and commercial applications in Indonesia, offering strong power density, wide fuel availability, and proven long-term reliability across a broad range of environmental conditions.

Natural Gas generator sets are increasingly favored by facilities with access to a stable gas supply, offering lower emissions and, in many cases, reduced fuel costs for continuous or prime power applications.

LP Gas (Liquid Propane) configurations offer similar emissions advantages to natural gas while providing greater flexibility for sites without direct pipeline access, using stored propane as an alternative fuel source.

Our engineering team works directly with clients to evaluate fuel availability, operating costs, emissions requirements, and site logistics before recommending a configuration — ensuring the final decision is based on the specific realities of each project, not a one-size-fits-all recommendation.

Frequently Asked Questions

What is the difference between prime and standby generator sets?

A prime generator set is designed for continuous or variable power supply in situations where utility power is unavailable or unreliable, and is built to run for extended periods, sometimes as the primary power source for a facility. A standby generator set, by contrast, is intended purely for emergency backup — it activates automatically when utility power fails and is not designed for continuous long-term operation. Selecting the correct category is critical, as using a standby-rated unit for prime power applications can significantly shorten its operational lifespan.

How do I choose the right generator capacity (kVA) for my facility?

The correct capacity depends on your total electrical load, including the startup or inrush current required by motors, compressors, and other equipment that draw significantly more power at the moment of activation than during normal operation. Underestimating this figure is one of the most common — and costly — mistakes in generator selection. Our engineering team conducts a detailed load assessment and sizing consultation for every project, ensuring the generator set you select genuinely matches your facility’s real-world power requirements rather than a rough estimate.

Does PT Elbrus Power Sistem provide installation and after-sales service?

Yes. As the authorized Rehlko distributor in Indonesia, we provide complete end-to-end service — from engineering consultation and site assessment, through installation and commissioning, to preventive maintenance and genuine spare parts support. Our relationship with clients does not end at delivery; it continues for the operational lifetime of the equipment.

What fuel types are available for Rehlko generator sets?

Rehlko generator sets are available in diesel, natural gas, and LP gas configurations, giving clients the flexibility to choose the option best suited to their site conditions, budget, and environmental goals.

How long does it take to install an industrial generator set?

Installation timelines vary depending on generator capacity, site readiness, and project complexity — a small commercial unit may be installed and commissioned within a matter of days, while a large-scale, multi-unit data center project can take several weeks to months from procurement through final commissioning. During the initial consultation, our team provides a realistic project timeline based on your specific scope.

Can Rehlko generator sets be configured to run in parallel?

Yes. For applications requiring higher total capacity, redundancy, or phased scalability, multiple generator sets can be configured to operate in parallel using synchronized control systems. This configuration is commonly used in data center and large industrial projects, where system redundancy is essential to maintaining uptime even if one unit requires maintenance or experiences a fault.

What ongoing maintenance does an industrial generator set require?

Routine maintenance typically includes regular inspection of fuel, oil, and coolant systems, filter replacement, battery testing, and periodic load testing to confirm the unit will perform correctly when needed. PT Elbrus Power Sistem offers scheduled preventive maintenance programs using genuine Rehlko parts, helping clients avoid the unplanned downtime that often results from deferred or improperly performed servicing.
