To heat an industrial area of 2000 m², 33 air conditioning units was used at full power. Due to heavy fouling on both sides of the units the capacity was not enough and extra heating units was needed to keep the temperature at acceptable level. This meant elevated costs for electricity and a decision had to be made, replace or clean the existing 33 units. After a price comparison the choice fell on the cleaning option.
RESULTS
After cleaning, the inlet temperature could be lowered from 60°C to 35°C and half of the air conditioning units could be disconnected.
