Install a Cochran Economiser... Achieve up to 95% efficiency* and fuel savings in excess of 6%. With payback in
under a year.

The use of an Economiser can greatly reduce fuel consumption by utilising boiler flue gases to heat water for
process services or to preheat boiler feed water. Cochran design and manufacture Economiser systems complete with
all associated equipment to raise feed or returns water from a heating system.
Cut fuel consumption, reduce emissions, save money
Cochran's compact Economiser units transfer the heat held in the boiler's exhaust gases into the feed water BEFORE
it enters the boiler, increasing the boiler's overall thermal efficiency. Improving thermal efficiency cuts fuel
use, resulting in significant cost savings and reduced emissions.
In fact, the capital cost of fitting a Cochran Economiser is usually recovered within 12 months.
Whilst they are normally fitted to natural gas-fired boilers, specially designed units may also be fitted to Liquid
Fuelled Boilers. Each unit is supplied complete with all the associated equipment required.
For both new and existing installations
Cochran's Economiser units can be supplied to fit every make and model of boiler, new or old. Each unit is supplied
complete with all necessary valves and gauges.
The Economiser's controls are interlinked with boiler feed water regulating valve to ensure a flow of water through
the economiser at all times.
Whether boiler-mounted or installed in a standalone format, every Cochran economiser is lagged and clad to maximise
efficiency. Ideally, economiser units should use a vertical gas flow. If site conditions require a horizontal gas
flow, then additional vent and drain connections are fitted.
Benefits of Cochran Economisers
-
Environmental: An economiser substantially reduces overall emissions and consumption of global
resources.
-
Cost Savings: Our Economiser will reduce a boiler's overall fuel consumption by more than 6%.
-
Flexibility: Units can be constructed to suit the geometry of the site and can be fitted to
suitable heat sources.
-
Retrofit: Whilst today almost every Cochran boiler is supplied with an Economiser already in
place, we design, build and retrofit units to fit every make of boiler, no matter how old it is.
-
Maintenance: Our Economisers have ease of maintenance and reliability designed-in.
-
Efficiency: Every Cochran economiser delivers an increase of 5% in efficiency, increasing to 6%
at turndown.
