Over the years we have
been asked to make specialist refrigeration units covering
a wide range of applications such as coffin coolers, maggot
fridges, blood fridges and a unit to preserve a 3,000 year
old peat bog body. Using our expertise in refrigeration we
were asked to design a unit that would recover petrol vapour
from the air that is displaced from the underground tank when
it is being filled by a road tanker. This vapour would normally
be vented to atmosphere but we found that approximately 50
litres of petrol can be recovered per tanker delivery.
This is achieved by quickly
cooling the vapour to below minus 40 degrees centigrade and
condensing it back into liquid, He recovered petrol is then
returned to the underground tank. Units have been exported
to China, India and installed at supermarkets in the UK. Vapour
Recovery units are proving to be cost effective and environmentally
friendly
