ABAC’s Alup Energy Box converts
the heat generated by most air
compressors into hot water up to
70ºC, for industrial processes or
washroom use. Replacing the energy
normally used to fuel boilers or
heaters, it saves on fuel costs.

It provides an easy-to-install
packaged system that can be fitted to
any make of oil injected rotary screw
compressor up to 90kW. It recovers
energy from the oil circuit on the
compressor via a heat exchanger,
giving a quick return on investment.

The company says that with a
relatively small 37kW compressor,
for example, the energy available for
recovery can be up to 29.9kW which
may equate to annual heating costs
of over £6000 (based on 4000
operating hours). Operating with
larger compressors or for longer
periods can result in greater savings.
