  1. Features

    • Saves up to 50% on energy costs by using municipal or well water to precool milk, significantly reducing operating time and wear-and-tear on your cooler’s refrigeration system
    • Durable, rust resistant, type 304 stainless steel end frames and stainless steel compression bolts are maintenance-free with no paint to crack or peel
    • All AT-20 models have snap-in gaskets for ease of inspection
    • Top quality, type 316 stainless steel plates for sanitary milk contact surface
    • Clean-in-place system reduces cleaning time and keeps maintenance costs low
    • The Accu-Therm DFE plate heat exchanger, used with a Mueller chiller, can cool milk to 37°F (2.8°C) in less time. This maintains high milk quality and impedes bacteria growth

Our Paul Mueller Company plate coolers, also known as plate heat exchangers, enable you to reduce refrigeration costs by utilizing your water supply. With our Accu-Therm plate coolers, you can precool warm milk before it enters your milk cooler by using your existing water supply. The warm water, after being used in the cooling process, is then available for animal consumption at your dairy facility. This precooling process can reduce the time and energy needed to achieve the proper temperatures in your bulk tank by as much as 50 percent.

Our Accu-Therm plate coolers consist of a series of stainless steel plates compressed into a sturdy frame. These plates are separated by gaskets that create flow channels on either side. Cool water flows down the channel on one side while warm milk flows up the opposite side. As the warm milk travels through the plates, its temperature decreases by transferring heat to the cool water. This efficient design allows for rapid precooling, ensuring optimal performance in your dairy milk cooling system.
