Greenhouse Greenhouse Cogeneration / CHP Benefits
Cogeneration / Gas engines are highly efficient at
providing the stimulus for the growth
of plants, whilst in parallel providing

product support. CO2 can be scrubbed and used to
promote plant growth.
Whether your requirement is for the supply of a single gas
engine generator or a complete turnkey power generation
facility, we can meet that need. Our ability to add value by
offering an end-to-end service, from initial proposal to
reliable long-term maintenance, has led to us becoming a
multi-national company with operations in ten countries
across the globe. Our company prides itself on integrity,
delivering only the highest quality products whilst providing
a reliable accountable localised service.
