Surface freezing On the entire surface NONE
Bursting of small blood
vessels
Renewed parasitic condensation
Air temperature in the
cooling tunnel
Chill temperatures during
the suction
Often in the bones and in the
fat

Necessary energy 1.5 to 2 kWh/pig 0.6 to 0.8kWh/pig
Costs of the cooling
plant
Maintenance and wearing
off of the plant
50% more expensive than mist
cooling
high
Very low
Wall insulation Thickness 160mm Thickness 80mm
Care and maintenance
Thawing to be done each
weekend, frequently thermal
shocks on the soil,
Repairs necessary every five
years
Care and cleaning simplified
by the positive temperatures.
No frost, no wind, no soil
problems
