Tunnel ventilation

Tunnel ventilation is the ideal solution for hotter climates. The system operates by using negative or positive pressure to create high air speeds and high air exchange rates which produces a desired cooling effect.

A barn equipped for negative pressure Tunnel ventilation will have inlet openings at one end and large exhaust fans on the other end. Fresh air enters the barn through the inlet openings and is removed through the exhaust fans.

During the winter or colder periods, the same concept can be used with fewer air exchanges which is achieved by using smaller curtain openings and fewer fans.

Pad cooling or high-pressure cooling can be added to reduce the incoming air temperature.

Benefits of applying SKOV-SECCO’s Tunnel ventilation:

• Low initial costs
• Temperature stability within the livestock house
• Energy-efficient running cost
• Environmental stability will increase farmers’ profitability
• Cooling through air velocity
• No wastewater from the evaporative pad cooling
• Removal of excess heat and harmful gases
• Dry and comfortable bedding
• Efficient and easy climate control
• Healthy and productive cows

Equip your tunnel-ventilated barn with:

• BF 50 wall fan 
• BF 55 wall fan
• MegaFan DD wall fan 
• High-pressure cooling
• Roll-up curtain 
• Roll-down curtain 
• Pad cooling 
• Boreal Flow recirculation fan
• VHV 55 & 72 recirculation fan
• BF 50 SuperFlow stir fan
• BlueControl climate controller 

Making Tunnel ventilation work effectively requires careful design and high-quality ventilation equipment. SKOV-SECCO has over 24 years of experience in designing ventilation for livestock houses mainly dedicated to dairy, and we have installed many Tunnel-ventilated barns in multiple countries.
