Farm Equipment - Plate Heat Exchangers
Why Buy Efficient Plate Heat Exchangers?
Energy savings of up to 55%
You can reduce the amount of energy needed to chill milk by up to 55%. This equipment can lower milk temperature from 36°C to anywhere between 16°C and 21°C before it goes to the tank, where it is kept at 3°C.
To be able to use a plate heat exchanger on your dairy farm, you need access to a year-round supply of cold water nearby (well, aqueduct, lake or river).
Typical energy savings
Take the example of a plate heat exchanger installed at a typical dairy farm that has a herd of 55 cows in milk.
| Milk tank compressor*
Some more recent milk tanks use screw compressors, which are considered to be more reliable and quieter.

Annual dollar savings**
The dollar savings estimate is based on the mean rate of 7¢/kWh over a year (2,750 kWh x $0.07 = $192.50).
|
|---|---|---|
| Power consumed 6,200 kWh/year |
Energy savings -2,750 kWh/year (± 45 %) |
$192.50 |
The greater the volume of milk handled, the shorter the payback period for purchase and installation.
Other advantages
- Improved milk quality
- Longer tank compressor life thanks to shorter running time and lower risk of overheating
- Prewarmed drinking water for livestock
