Key benefits

Outstanding cooling performance with a small footprint

Thanks to the high air velocity and cooling capacity of the cooling tunnel the products are cooled down quickly and efficiently in a cooling tunnel of the shortest possible length.

Easy access for cleaning and maintenance

Fabricated in stainless steel with easy access for cleaning and maintenance.

Efficient insulation saves energy

The use of effective high-quality insulation and excellent seals saves energy and allows better temperature control in the cooling tunnel for repeatable product quality.

High-efficiency cooling tunnel

Efficient product cooling

High air velocity and cooling power

Our high-efficiency cooling tunnel is designed to operate with a high air velocity in combination with an outstanding cooling power in order to cool down hot products efficiently and quickly. This means that the cooling tunnel can be the shortest possible length in order to save space.

Operating principle

Convection cooling and water-cooled bottom plates

For uniform and efficient cooling results the products are cooled from the top using convection air cooling and from the bottom using water-cooled bottom plates.

Food safety

Stainless steel design version

The cooling tunnel is made of stainless steel ensures high standards of hygiene. As well as parts that come into contact with the product, the cladding, hoods and frames are also made of stainless steel.

High quality sturdy design

Effective insulation and excellent seals

Alongside the precise temperature control, the air velocity and cooling power, as well as the insulation and seals are important for efficient cooling by preventing condensation and air leakages. Bühler's cooling tunnels are characterized by their proven insulation quality and thickness as well as by their air-tight seals on the hoods and the coil section.


Modular setup

The cooling tunnels have a modular design, which enables them to fit the product space requirements.
