For Milk Coolers

Improve energy efficiency and dairy farms’ competitiveness, reduce the ecological footprint of milk production are Ecolacteo goals.

Ecolacteo adapts to the milk cooling tank and recovers milk’s heat, normally lost during cooling; the heat recovered is used to preheat the hot water needed for cleaning dairy equipments.

Ecolacteo is a new generation heat recovery system:

– An unmatched level of energy efficiency in heating and cooling
– A hot water production system adapted to dairy farms’ requirements.

An exclusive patended functioning mode which optimize heat recovery, cooling performances and energy performance of milk cooling tank.

Two successive functioning modes during the same cooling cycle:

1/ “Water condenser” mode: The heat recovery system condenses all the refrigerant gas using the cold water from the water tank. It recovers all the heat rejected by the cooling unit to heat up water very quickly to a minimum temperature of 55°C, whatever the ambient temperature. Fans are stopped.

2/ “Desuperheating” mode: when all the water has been preheated, fans are switched on.

The heat recovery system continues heating up the water (gas desuperheating); water can reach a temperature of 65 / 70°C in summer.

The system runs within the operating envelope of the compressors (pressure and compressor temperature);
Water condensation improves the compressor efficiency in summer and avoids high pressure cut-off.

The 26 bars HP safety pressure switch restarts ventilation in case of water circuit dysfunction: priority is given to refrigeration.
