|Free (!) heating of water from milk.|
|Considerable savings when using well or mains water as pre cooling. Up to 50 % less energy consumption when cooling the milk.|
|No maintenance. The Unitech tubular cooler need never be dismantled for cleaning purposes, contrary to a plate cooler or bundle tubular cooler!|
|Easy cleaning, together with the milking machine.|
|Immediate milk cooling slows bacterial growth.|
|Low blend temperature during subsequent milkings. Less chance of bacterial growth.|
|No seals, the milk is only in contact with stainless steel. This avoids pollution or contamination. Very reliable in comparison with plate cooler or bundle tubular cooler.|
|The heated water can be used as drinking water for the cattle. The animals like to drink warm water. They drink more; the milk production remains stable, also during wintertime. Tests on the farm have proven this.|
|Possible subventions for environment friendly solution|
|Smaller cooling unit possible. This means lower investment|
|Short return on investment (only a few years)|
|Suitable for spring water|
|Very long life expectancy|
|No maintenance costs|
The milk is pre-cooled very rapidly with well water to a temperature of about 20°C. This means considerable lower energy consumption when cooling further down to 4°C (green curve).
The milk is cooled immediately (instant cooling ) below the critical limit of 10°C with ice water. The bacterial growth is halted at once (blue curve).
