Stephill SSDP70 Super Silent Three Phase Diesel Generator | Perkins Engine
The Stephill SSDP70 Super Silent Three Phase Diesel Generator is engineered for demanding professional applications where dependable power, low operating noise and straightforward control are essential.
Suitable for industrial sites, commercial premises, agricultural operations and standby-power installations, the SSDP70 combines a reliable Perkins diesel engine with a high-quality Mecc Alte alternator and a robust acoustic enclosure.
Important Delivery and Offloading Information
Due to the size and weight of this generator, suitable mechanical offloading equipment will be required at the delivery address.
The customer must arrange access to a:
- Forklift
- Telehandler
- Crane or suitable lifting equipment
Offloading equipment and labour are not included with delivery. The site must be accessible to the delivery vehicle, and the customer is responsible for safely unloading and positioning the generator.
Super-Silent Acoustic Enclosure
The SSDP70 is housed inside a close-fitting acoustic cabinet designed to reduce operating noise while protecting the generator’s internal components.
The enclosure is manufactured from Zintec steel, helping provide resistance against corrosion and demanding outdoor conditions.
Large access doors allow convenient entry for servicing, inspection and routine maintenance. An optional skid base may also be available depending on the selected configuration.
Perkins Water-Cooled Diesel Engine
The generator is powered by a professional 1500rpm Perkins water-cooled diesel engine.
Low-speed 1500rpm operation is particularly well suited to standby and continuous-duty generator applications, helping provide:
- Smooth operation
- Reduced engine wear
- Improved durability
- Lower operating noise
- Dependable long-term performance
The engine protection system includes automatic shutdown for high engine temperature and low oil pressure.
Deep Sea DSE6110 Controller
The integrated Deep Sea DSE6110 controller provides simple push-button starting and stopping.
A two-wire remote-start facility is also included, allowing the generator to be activated by compatible external equipment or an appropriately configured Automatic Transfer Switch.
The lockable control-panel door helps prevent unauthorised access and protects the controls when the generator is unattended.
Mecc Alte AVR Alternator
The SSDP70 uses a maintenance-free brushed Mecc Alte alternator with Automatic Voltage Regulation.
The AVR system maintains the output voltage to approximately ±1%, helping provide a stable electrical supply for connected equipment.
The alternator also benefits from Mecc Alte Total Winding Protection and is covered by a limited three-year manufacturer’s warranty, subject to the applicable terms and conditions.
Three-Phase and Single-Phase Power
The generator provides both:
- 400V three-phase output
- 230V single-phase output
An Earth Leakage Circuit Breaker is fitted to the 400V/230V output to provide additional electrical protection.
Each socket is individually protected against overload, while a hard-wire connection facility allows the generator to be incorporated into suitable fixed installations.
Installation and connection must be completed by a suitably qualified electrician.
External Fuel-Tank Connection
A three-way fuel valve allows the generator to be connected to an external bowser or bulk fuel tank.
An additional fuel-transfer pump may be required depending on the location, height and configuration of the external tank.
Suitable Applications
The Stephill SSDP70 is suitable for:
- Industrial premises
- Commercial buildings
- Agricultural operations
- Workshops and factories
- Construction and infrastructure projects
- Emergency backup power
- Temporary site power
- Equipment hire
- Fixed standby installations
- Remote-start and ATS applications
