    Cool your milk with recycled CO2 to save energy and money. Read more about DFC953/95 here >>

    We offer powerful milk cooling solutions with focus on quality and cost efficiency. Our product range includes two types of horizontal tanks, the DF953/DF95 and DF953L/DF95L. Both have a robust and versatile construction and a hygienic design, made completely out of high-quality stainless steel. They are available in various sizes, designed to fit any type of milking system. The tanks are placed on a sturdy frame with adjustable legs for easy transportation. Both the legs and the agitator motor can be dismantled to facilitate installation. All our tanks are built with laser-welded evaporators and the unique evaporator pattern secures a slow movement of the refrigerant and thus an efficient cooling. The inner tank is lying only on the thick insulation foam, which secures optimum insulation characteristics with minimum temperature fluctuations. This makes our milk cooling tanks energy-efficient and cost-saving.

    An optimized cooling system lowers your operational costs
    Our cooling systems are of modular design, which means that we offer solutions tailored to customer needs regarding milk quantity, ambient temperature, required cooling time and collection frequency. Thanks to the evaporator, the refrigerant, which is the most environmentally friendly on the market, is lead through a long circulation route to promote even more cost- and energy-efficient cooling. As an option, the heat from the milk can be recovered and used for warming up water for your farm’s daily needs for cleaning or heating; a sustainable and cost-saving solution.

    Here you can read more about our cooling units.

    Vertical milk cooling tanks (Silo) 5,000 to 50,000 litres

    The demand for large-volume milk tanks is continuously increasing, which makes storage space a critical issue. Wedholms’ vertical silo tanks provide an excellent cooling solution when space is limited. The robust silo tanks in stainless steel can hold 5,000 to 50,000 litres of milk and are offered in two diameters for increased flexibility. The vertical design allows flexible placement, ensuring easy access for milk collection as well as service and maintenance. The silo tank is delivered in a complete package, with a separated cooling unit adapted for either conventional or robotic milking systems, as well as an Argos control unit pre-mounted to the silo.

    Read more about the Argos control system.

    Our silo tanks take care of your milk from the very first liter entering the tank, and together with a range of other features, this makes the Wedholms silo tank an ideal choice in combination with your automatic milking system. However, if pre-cooling is used, a silo tank can also be a very good alternative on conventional dairy farms. The silo tanks are designed to save both energy and the environment. Lower energy costs of course also mean a greater profitability for you as a dairy farmer. Thick, high-quality insulation in the bottom, top and side walls of the silo secures optimum thermal protection and improved compressor lifetime. The refrigerant, R134a, is one of the most efficient and environmentally friendly refrigerants available on the market today.

    Did you know that you can use the heat from the milk to warm up the drinking water for the cows or water for cleaning and heating purposes on the farm?

    Argos control system

    To further optimize the milk cooling process, the Argos control system offers an excellent overview and easy access to several critical data, such as milk temperature. Advanced technology allows customized adjustments of functionality, cleaning process, agitation etc., according to local conditions.

    Read more about the Argos control system.

    Further benefits

    There are several features for quick and efficient cooling. For example, each condensing unit is tailor-made for a specific tank size and the silo tanks are equipped with three evaporators, two in the bottom and one on the side wall, with the option to add more evaporator space to the wall. Efficient cooling goes hand in hand with hygiene and quality. This is why the temperature sensor in the bottom of the tank never comes in contact with the milk. Together with our milk outlet with separate cooling, this secures excellent hygiene and optimum milk quality.

    Options
    The Wedholms silo tanks are of a high standard also in the basic version, but there are a number of options and accessories that add to a fully customized solution: ladder with safety cage, self-cleaning outlet for milk sample collection at the manhole, milk level sensor, and energy-saving pre-cooling units, to name a few. The manhole can be placed in various positions around the silo tank.
