Why HNYZ Group
It depends on the design and the air. We discuss targets with you.
Water, power and chemicals are the main costs.
From the house volume, pig number and peak outside temperature. We calculate the airflow and propose the fan count.
In hot climates, pads cool incoming air by evaporation and are common. In cold climates, heating matters more.
Yes. Controllers can sound an alarm when temperature goes out of range, and monitoring can be added.
Houses need a plan for power cuts: alarms, a generator, or emergency openings. We discuss options with you.
Fan power is a major part of running cost. Variable-speed fans and good design can lower it.
No. Dimensions, materials and configuration are customised to your herd size, climate and local rules, and agreed with you before quotation.
They are typical reference values to help you compare. Final specifications are confirmed with you before quotation.
