For many years, SEP has included in our range what we call the ‘Duplex compressor station’, which as far as we know is a unique offering (not the only unique product in our range, either).
Over the years its principles of operation have effectively remained the same, but like many of our products the design has evolved – to meet more customer requirements, minimise the overall size, reduce the number of components, improve visual appearance, and keep costs reasonable. Our volume of enquiries and shipments for this specialist piece of equipment are increasing, so we thought it would be useful to summarise some key features.
How a Duplex Compressor works:
- Two pumps, two switches, two motor switch sets – one compact unit
- AUTO: control panel alternates the cut-in of the pumps, or runs both together when pressure is very low
- MANUAL: can select either pump to run exclusively
Benefits of a Duplex Compressor:
- Alternating wear on pumps during normal auto-maintenance operation
- Double power output for first-fill or re-fill from empty (or low pressure)
- Switch to manual, enabling maintenance of either pump
- Automatic backup in case of failure of either pump, pressure switch, contactor or thermal overload
- LED indicators for pumps running, at-pressure or tripped
- In-person training offered at SEP or, for large/local projects, on-site
Optional extras:
- Power supply failure relay, to send signal to external monitoring panel
- Pump run-time counters to allow periodic manual monitoring of each pump’s usage
- Automatic timer drain on air receiver to ensure no build-up of water
- Integrated pressure switch to send signal to external monitoring panel
- Wall-mounting configuration (floor-mounting is standard)
Our unique duplex compressor station is designed and built at our own factory, so in line with most of our products, we can be as bespoke as you need – the optional extras are no problem, and we can currently build the duplex using any of the same pumps we use on our other models (SEP0.7S/OFQ, SEP1.5S, SEP1.5S/OFS, SEP1.5S/OFQ, SEP1.8S, SEP1.8T).
