Energy-saving solutions

Natural resources are limited and energy is expensive and thus one of our main focus areas is energy-efficiency. For you as a customer this means that with a milk cooling tank from Wedholms, you can be sure to make a good choice regarding energy consumption and profitability.  Below, you can find out more about our energy-smart options, which will help you to keep costs down and support the environment. Did you know for example, that the heat energy from the milk can be used to heat up the cows’ drinking water or pre-heat cleaning water for the barn?

    CO2 by Wedholms

    With CO2 by Wedholms, we are stepping into a new era of milk cooling where we contribute to the dairy entrepreneur’s ability to achieve the goals for reduced climate emissions while benefiting the operating economy.

    Benefits of CO2 by Wedholms:

    • Reduced energy use (up to 50%)
    • Efficient heat recovery as standard (> 70 degrees Celsius)
    • Benefits the operating economy and the climate
    • Optimal milk quality
    • Plug & play installation

    For a number of years, there has been a technology for recovering CO2 emissions from industry, which is then used as a refrigerant in various industries. We at Wedholms have for several years developed and tested a new milk cooling tank with the goal of using CO2 emissions from industry to cool milk on the farm. We are now shortly before the launch of our unique and patent-protected solution CO2 by Wedholms. We expect to be able to launch the system for robotic dairy farms in 2021.

    The benefits of using CO2 instead of traditional refrigerants are many. First, CO2 has a low climate footprint, making it one of the most environmentally friendly refrigerants on the market today. CO2 is also very efficient as a refrigerant, both in terms of cooling and heat recovery. It is also a natural gas that is not harmful to the user in the quantities used and it is also not explosive like other natural gases. All in all, CO2 is a excellent alternative as a refrigerant on a dairy farm.

    The powerful properties of CO2 as a refrigerant in combination with the technical solution with frequency-controlled compressor means that CO2 by Wedholms provides energy savings of up to 50%. In addition, the system is equipped with efficient heat recovery as standard, which means that hot water is produced for free. Since the temperature of the heated water is above 70 degrees Celsius and the amount covers the double need for the tank cleaning, there is a lot of money to be saved for the dairy farmer while the solution also is very favorable for the climate.

    We believe that CO2 by Wedholms is the melody of the future and we are proud to be able to contribute to a reduced climate footprint in milk production and better profitability on the dairy farm. Welcome to contact us for more information about CO2 by Wedholms.

    Interpac heat recovery

    The Interpac uses the energy generated during the cooling process to heat water to about 40-45° Celsius. This energy would otherwise have been ventilated from the condensers, meaning that it would either have warmed up the milk room or been wasted outside. The warm water can be used for example as drinking water for the cows, if it is mixed with cold water. It can also be stored in a water tank and used for e.g. cleaning or heating purposes on the farm. This will save both energy and money.

    Advantages with Interpac:
    • Short payback time of investment costs
    • Uses excess heat energy from the cooling process to heat water
    • Supplies you with warm water “for free”
    • Your cows can get warmer drinking water, drink more and produce more milk
    • Environmental-friendly
    • Decreases your costs and increases your profitability
    • Can be retrofitted to an existing installation

    The size (amount of plates) of the Interpac is depending on the cooling capacity and if a receiver is installed. The more plates, the more warm water can be produced, but the number of plates has no impact on the temperature of the water.

    When ordering condensing units with several cooling compressors it is possible to order as many Interpacs as there are compressors. If fewer Interpacs are ordered than compressors, the Interpacs are installed on the compressors that start first. If two compressors are connected to the same condenser, either both or none should be equipped with an Interpac.

    To maintain a good function of the cooling system, not all potential energy should be removed from the Interpac, unless the system is equipped with a receiver. The Interpac can be factory-mounted or retrofitted on farm by a certified cooling technician.
