Our immersion coolers for milk cooling
When it comes to milk cooling, efficiency and reliability are key. Our immersion coolers offer just that: fast and reliable cooling directly in the milk tank. This guarantees outstanding milk quality and extends shelf life.

Advantages of our immersion coolers:
- Efficient cooling: Our immersion coolers ensure a rapid reduction in milk temperature, which inhibits bacterial growth and preserves the quality of the milk.
- Robust construction: The durable materials and solid construction ensure a long service life and reliable operation.
- Simple installation: Our immersion coolers are easy to install and integrate into existing milk cooling systems.
- Energy efficiency: Thanks to state-of-the-art technology, our immersion coolers are energy-efficient, which reduces operating costs.
Why immersion coolers from Lister?
We understand the needs of our customers in the agricultural sector and offer customised solutions for milk cooling. Our immersion coolers are the result of years of experience and continuous innovation. They not only offer excellent cooling performance, but also easy handling and maintenance.
The electronic milk thermostat ensures a constant milk temperature and is infinitely variable. The LISTER milk agitator ensures gentle treatment of the milk, even with very small quantities of milk. The agitator motor is vacuum-proof, protected by a winding thermostat and mounted on ball bearings.
LISTER immersion coolers are equipped with a digital temperature display as standard. An automatic cycle prevents the milk from creaming. Retrofitting of a heat recovery system is possible. The refrigerant used is R134a.
Special feature:
The newly developed freely programmable controller offers flexibility for special applications.
Other possible applications:
- Brine cooler: The housing of the unit is also available in stainless steel for cooling brine, for example.
- Immersion cooler for industry: For cooling water or emulsions. Also ideal for use in distilleries, for example.
