VentMax units are designed to reduce emissions from air leaving your poultry house. At the same time they deliver efficient heating and cooling, whilst maintaining a calm, environmentally-controlled shed.

How does VentMax work?

  1. Dirty air leaving the shed passes through a filter to remove large particulates of dust.
  2. The air then passes through a fan and heat exchanger.
  3. The heat exchanger removes excess heat and the heat is transferred into the incoming fresh clean air supply.
  4. The outgoing air finally passes through an air scrubber system to remove ammonia gases, odour and any remaining small dust particulates.
  5. The air is then exhausted at high velocity through a stack.
  6. Filtered incoming air passes over a coil which either adds heating or cooling to condition it before entering the building to maintain the target temperature.
  7. Air is distributed into the shed using high velocity nozzles to ensure it reaches the centre of the shed without causing wind chill at bird level.

Ventmax - how it works
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

7

Supply Air 3.5 cubic metres per second

The air scrubbing and extraction process

The air leaving the shed is treated using a filter to remove any large particulates of dust. It then passes through a fan, and then a plate heat exchanger, where the heat is removed and used to heat the incoming clean air supply.

The outgoing air is then passed through an air scrubbing system to remove any remaining small particulates from the air stream. The scrubbing system also removes ammonia gasses to reduce the levels of ammonia and odour emissions discharged to the environment.

Finally, 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.

Air scrubber features

Temperature-controlled, filtered air

When the supply air enters the building it is initially filtered. It then either passes through the plate heat exchanger to recover heat from the outgoing exhaust air or bypasses this if no pre-heating is required. The air then flows over a coil which either adds heating or cooling to condition it before entering the building, in order to maintain the target house set temperature.

Heating & cooling

Plant control

VentMax has its own control system developed by IPT. This ensures return air temperatures and the house set point are kept consistent, regardless of external weather conditions. Our system’s intelligent monitoring and reporting capabilities offer a detailed analysis of shed conditions, ammonia emissions and plant operation.

When required, our controls can be fully integrated with your own building management system, providing one tool to monitor and operate your facility.
