Closed type milk coolers are designed to store and maintain milk at an optimal temperature under conditions of full hygienic protection. These are vertical or horizontal hermetic tanks made of food-grade stainless steel, equipped with a high-efficiency cooling system and automatic washing.
The closed design eliminates contact between milk and the external environment, preventing the ingress of dust, insects, and other contaminants, preserving the initial quality of the product from the moment of milking until shipment for processing.
Advantages:

• Rapid milk cooling to +4°C and temperature maintenance.
• Full hermeticity and protection from external factors.
• High energy efficiency due to modern refrigeration equipment.
• Compatibility with CIP washing systems for automatic sanitary cleaning.
• Robust thermal insulation for minimal heat loss.

Closed type cooling tanks are the optimal solution for modern dairy farms where stable product quality, compliance with sanitary standards, and resource saving are important.

Open type milk coolers are equipment designed for cooling and short-term storage of milk with easy access to the internal reservoir. The design consists of a cylindrical or oval tank made of food-grade stainless steel with an opening lid and a built-in cooling system.
Thanks to the simplicity of the design, such coolers are convenient to operate and maintain, and also allow for visual monitoring of the milk level and condition.
Advantages:

• Rapid milk cooling to +4°C while preserving quality.
• Convenient access for manual washing and inspection.
• Simple construction and easy maintenance.
• Optimal solution for small and medium-sized farms.
• Reliable thermal insulation for minimal heat loss.

Open coolers are often chosen by farmers who value a simple and cost-effective solution for cooling milk at small production volumes, without complex automation and with the possibility of manual control.

In-line cooling is a technology where milk is cooled immediately during the milking process, even before entering the cooling tank. A special heat exchanger (chiller) is used for this, through which milk passes in a thin layer, instantly transferring heat to the cooling liquid (coolant).
This method is especially effective in farms with high yields and in regions with high ambient temperatures. It allows reducing the load on the main cooling tank and ensuring maximum product freshness.
Advantages:

• Instant milk cooling to +4°C.
• Minimization of bacterial flora growth.
• Reduction of load and energy consumption of the cooling tank.
• Increased milk storage life without loss of quality.
• Maintenance of stable temperature even during intensive milking.

In-line cooling is a modern solution for farms striving for the highest milk quality and optimization of energy resource costs.
