Compressors certified for 100% energy recovery
September 1st 2009 The latest range of air
compressors from Atlas
Copco are said to be Carbon
Zero. They have advanced heat
recovery systems that, the company
says, recover 100% of the electrical
energy input in the form of hot
water. They can, as a result, reduce
energy costs for a wide range of
industries.
The TÜV institute (German
Technical Monitoring Association)
earlier this year supervised tests on
Atlas Copco's oil-free screw
compressor series ZR 55 – 750 with
built-in energy recovery systems.
Tests showed that, under specific
design conditions, 100% of the electric
energy consumed could be recovered
for heating water.
The Carbon Zero innovation
provides effective heat transfer,
within specific design conditions, of
relative humidity so that a
considerable proportion of electrical
power input can be recovered in the
form of hot water at 90°C. This
provides benefits for industries
employing hot water or steam within
process operations such as food and
beverage, pulp and paper, chemicals
and power plants.
By using the compressor output
hot water either directly, or as preheated
boiler feed water, the
consumption of process heating fuel
and its associated carbon dioxide
emissions can be dramatically
reduced or, in some cases, eliminated. More articles from Atlas Copco Ltd: |
