FlexEgen — Acoustic Generator Enclosures
Power Generation Environments for:
- Diesel generators
- Gas generators
- CHP (combined heat and power) systems
- DRUPS (diesel rotary UPS) systems
- Multi-generator power plants
DeliversA complete operating environment for power generation equipment.
FlexEgen is an engine-agnostic acoustic enclosure for diesel and gas generators. The enclosure is designed around the genset — ventilation, exhaust routing, fuel and acoustic treatment all sized to the engine. Standard UK build includes a bunded floor.

FlexEgen assembly
FlexEgen factory assembly — Cummins QSK engine being built and tested on the production line.
Three formats
One FlexEgen platform. Three structural base formats.
Every FlexEgen is the same acoustic enclosure family — chosen base format depends on fuel autonomy, site civils and installation method.
Dropover
Enclosure drops directly over a customer-supplied genset and bunded base. Minimal structural steel — maximum integration with existing equipment.
Integrated fuel tank
Structural base tank doubles as fuel storage and chassis. Bulk fuel autonomy in a single lift, with bunded containment built into the enclosure.
Skid base frame
Heavy-duty structural skid for craning and re-deployment. Sits on a slab or concrete plinth — engineered for transport and rapid relocation.

Scope
Standard, optional and what we never do
Standard
Included on every FlexEgen unit.
- Acoustic-rated enclosure shell (standard: 85 dBA @ 7.5m)
- Weatherproof cladding and structural base frame
- Ventilation louvres sized for combustion and cooling air (with airflow calculations)
- Exhaust system penetration / interface point
- Fuel line interface point
- Access doors for maintenance and servicing
- Roof bracket for muffler / silencer mounting
- Bunded floor (standard on all UK projects)
- Thermal insulation and corrosion protection
- Documentation package and lifting / transportation provisions
Optional extras
Specified per project, costed as add-ons.
- Enhanced acoustic package — down to 60 dBA @ 1m
- Electrical interface package — external cabinet(s) for cable connection, load bank, BMS/SCADA, ATS
- Enhanced fuel package — internal bulk tank, fuel level monitoring, bund leak monitoring
- Internal infrastructure, electrical building services, fire/safety, and security packages
Exclusions
Out of scope — owned by other trades.
- Power cabling termination — NEVER our scope
- The generator set itself
- Fuel storage beyond the interface point
- Exhaust silencer / piping beyond the penetration
- Control or ATS panel (unless separately specified)
WE NEVER TERMINATE POWER CABLING — THAT STAYS WITH THE ELECTRICAL CONTRACTOR / INTEGRATOR.
