SL-50 kVA

JAVAC Silent Diesel Generator – SL Series (15–250 kVA)

Built for quiet power, reliability and durability

The JAVAC SL series represents the latest generation of silent diesel generators for professional applications. Designed for intensive and long-term use, these generators combine power, silence and reliability in one compact and low-maintenance design.

Whether it concerns a construction site, an industrial installation, an off-grid energy system or an emergency power solution — the SL series delivers constant, stable power wherever and whenever you need it.

Onze generatoren hebben een 3-weg brandstofklep, waarmee eenvoudig kan worden geschakeld tussen de interne en een externe dieseltank. De aansluitingen zijn duidelijk en gebruiksvriendelijk.

Powerful engines – from Baudouin to Isuzu

Each generator is equipped with a speed-regulated Baudouin F-13260 Cassis engine (1500 rpm) for power ranges from 50 to 250 kVA. For lower power outputs (15–40 kVA), Hyundai (OEM) or Isuzu engines are used.

All engines are 1500 rpm water-cooled and are known for their long service life, low fuel consumption and exceptional reliability, even under heavy loads or extreme conditions. The combination with a high-quality Stamford alternator with AVR regulation (UK technology) guarantees perfectly stabilized voltage — ideal for sensitive equipment, lighting and electronic tools.

Built robustly for real jobsite work

The housing of the JAVAC SL series is made of high-quality galvanized steel, carefully treated against corrosion and finished with a weather-resistant industrial coating. This durable construction withstands dust, rain, mud and heavy jobsite traffic, allowing the generator to be placed outdoors without additional protection — all year round.

The fully enclosed and reinforced casing protects the internal components against moisture and mechanical impact, while the vibration-free silent block mounting contributes to a longer service life of both the engine and the alternator.

For easy placement, each unit is equipped with sturdy lifting eyes and practical forklift slots, allowing relocation and positioning to be carried out quickly, safely and efficiently.
This makes the SL series the ideal choice for temporary installations, construction and industrial sites, or off-grid energy setups where reliability and mobility are essential.

Smart energy concept – safe, efficient and future-oriented

The built-in Deepsea controller (UK) continuously monitors all critical parameters such as voltage, frequency, current, oil level and coolant level, etc. All important parameters — fuel level, oil and coolant status — are displayed not only digitally but also mechanically via analogue gauges on the control panel, ensuring the user always has direct visual feedback.

Each generator is equipped with CEE sockets, individually protected by automatic circuit breakers against short circuits and overloads. The entire electrical circuit is additionally secured by an industrial main RCD with adjustable sensitivity (30–200 mA), adaptable to the application and environment. On the exterior of the housing, a grounding point is provided as standard, allowing you to easily connect the generator to an external grounding rod or ground loop — for maximum safety in accordance with AREI standards.

In the event of any deviation, the system intervenes automatically — through a warning or safe shutdown — to protect the engine, alternator and connected devices. This ensures that the SL series delivers reliable operation with maximum safety, even during long-term or unattended use.

Nanomag technology – keeps performing where others fail

The exclusive Nanomag technology makes the SL series resistant to sudden peak loads. Where conventional alternators often drop out or show voltage loss, the SL series continues to perform stably — even when heavy machinery such as crane motors, welding machines, compressors or pumps are switched on.

Nanomag responds extremely quickly to current and voltage fluctuations, without overloading the engine or electronics. The result: constant performance and maximum operational reliability, even under the toughest conditions.
