VentMax is our proprietary full house ventilation, air scrubber and heat recovery system which delivers a range of financial, operational, welfare and environmental benefits, far in advance of conventional methods.

VentMax delivers a range of financial, operational, welfare and environmental benefits, far in advance of conventional methods. Once installed, VentMax will be run by a fully integrated control management system developed by IPT.

Designed to be quieter than conventional systems and featuring an advanced air scrubbing technology reducing dust, ammonia and odour emissions. Heat is recovered either for storage or to heat in-going air into the building. The shed temperatures are kept consistent regardless of external weather conditions and the building is controlled and managed using a system devised by IPT.

Heating

Heating is performed using the recovered heat from the shed with an expected recovery of 70% (average), with the balance from the ground source heat pumps, however, this can come from another source.

Cooling

Cooling is performed using indirect adiabatic, evaporative, passive (from the ground) and active cooling maintaining a constant shed temperature regardless of outside conditions.

Ventmax Working
1

The VentMax system treats the air coming out of the shed by removing the large particulates of dust through a filter.

2

The air is then passed through the fan

3

It then goes through the plate heat exchanger where the heat is removed

4

After the heat is removed the air is transferred into the incoming fresh clean air supply

5

The air is finally passed through an air scrubber system ensuring any remaining small dust particulates are removed from the air stream

6

The air will then pass over a coil which will either add heating or cooling to condition the air entering the building to maintain the target temperature

How does VentMax work?

The VentMax system treats the air coming out of the shed by removing the large particulates of dust through a filter (1) before being passed through the fan (2) and then plate heat exchanger (3) where the heat is removed and transferred into the incoming fresh clean air supply (4). The air is finally passed through an air scrubber system ensuring any remaining small dust particulates are removed from the air stream. As the air passes through the water fall system (5) where ammonia gasses are removed reducing the levels of ammonia discharged to the atmosphere together with reduced odour emissions. The air is exhausted at high velocity through a stack which can be adjusted in respect of height and velocity to suit local environmental requirements.

The supply air is filtered and will either pass through the plate heat exchanger which has recovered the heat from the dirty exhaust air from the house or will bypass this depending on whether the air requires pre-heating. The air will then pass over a coil (6) which will either add heating or cooling to condition the air entering the building to maintain the target house set temperature.

The air enters the house through directional nozzles which can be adjusted to suit the air flow pattern and distribution ensuring an even temperature and air movement throughout the house while keeping the air movement above bird height so as not to cause any risk of wind chill effect. The exhaust air is removed at eaves height above the supply nozzles removing the need to treat the air in the roof space in the same volumes as in the bird area, reducing energy consumption and effective treated air volume.

Each VentMax unit has a separate supply and exhaust fan which can be controlled individually allowing for greater control over each zone within the shed while maintaining the required pressure within the shed whether that be balanced, positive or negative. Each unit has an UFH manifold which can be individually controlled giving greater flexibility of temperature control from one unit.

The VentMax unit can manage the cooling and heating system as a standalone system or as part of a multiple unit system and can accommodate sheds of any size. The units work best with a ground source heat pump (GeoCube) storing the waste heat from the cooling cycle to be used in the heating cycle, with careful management of the passive and active cooling the system can be very efficient and help to reduce energy consumption.

Heating is performed using the recovered heat from the shed with an expected recovery of 70%(average), with the balance from the
ground source heat pumps, however, this can come from another source.

For VentMax + UFH, an overall ammonia emissions reduction of 40-60% at source (i.e. excluding the water spray chamber) is considered realistic and cautious in comparison with conventional systems. A 60% reduction could be justified if there is evidence to show that litter moisture contents are 25% or lower.

On the basis of a benchmark emission rate of 0.034 kg per bird place per year for broilers:

  • A 40% reduction would achieve ammonia emissions of 0.020 kg per place per year
  • A 60% reduction would achieve ammonia emissions of 0.014 kg per place per year.

Taking the same precautionary view as above on the effect of the waterfall system (i.e. 50% less effective than packed tower scrubbers), a further ammonia emissions reduction of approximately 35% could be achieved.
