Low-noise, High-efficiency Power Solution for the Rental and Events Market

ELCOS Power Generators, headquartered in the province of Cremona, Italy, has designed, produced, and assembled power generation systems for over 50 years. Serving both domestic and international markets, ELCOS specialises in customisable generator sets from 1 to 4150 kVA for emergency, self-generation, and cogeneration applications. The company supports the rental power sector, delivering flexible and dependable energy solutions.

Project Scope

ELCOS’s customer required alternators capable of maintaining exceptional performance in constantly changing conditions. Each rental deployment presents unique challenges, from environmental factors to load variability, demanding equipment that offers durability, quick adaptability, and minimal maintenance.

Solutions Development

To meet these requirements, ELCOS selected STAMFORD S5 alternators, paired with Scania DC16 078A 02 43 Stage V engines, for its mobile generator fleet.

The solution features a 700 kVA Twin-Power configuration, consisting of two fully redundant, synchronised units housed within a compact, highly mobile enclosure. To maximise efficiency and performance, the system is cooled using inverter-driven electric fans, significantly reducing noise levels while optimising thermal management. This configuration delivers a versatile, plug-and-play power source that complies with the most stringent low-noise emission requirements and enables rapid on-site deployment through quick-coupling connectors.

Technical Specifications

The STAMFORD S5 low-voltage alternator features enhanced thermal management through its CoreCooling™ high-efficiency airflow system and is equipped with the AS440 Digital AVR. Selected for its robust design and proven reliability, the S5’s compact footprint and ease of servicing make it an ideal solution for the demanding conditions of rental and temporary installations.

• Redundancy and synchronisation – Clearly emphasises operational continuity and backup capability.
• Cooling technology – Highlights inverter-driven electric fans as a key advantage for both noise reduction and efficiency.
• Compactness and mobility - Effectively links high power density to ease of transport and rapid deployment.
