As the water in the boiler circuit is at a very high temperature, when automatic blowdowns are performed, the water that comes out must have time to cool down before finally being poured down the drain. A blowdown cooler tank is used for this reason.
ATTSU manufactures the DF compact blowdown cooler in various sizes, ranging from 60 to 2,000 litres.
The DF tank is a compact blowdown cooler designed for use in any installation and steam boiler. ATTSU's DF tanks ensure that the water from the blowdown cools down and is evacuated at low temperatures.
