Air inlets

This advice applies to a temperate /cold climate.Depending on the width of the poultry house a choice is made between: › Flash › X-Stream › 4 Seasons

In the sidewalls Tulderhof places 70 to 80% of the total ventilation capacity.

For poultry houses from 18 meters extra tunnel inlets are often placed in the front wall. These tunnel inlets create a good wind chilling effect when it gets hotter. Up to 30% of the total capacity: Tunnel Twin. For blind spots and air inlets which can’t be placed in the fi rst bays extra air inlets could be placed in the front wall.

On the outside of the barn we advise to place winter doors in front of the Tunnel twins. This increases the insulation and reduces direct daylight.

Position of the air inlets: › The bottom of the air inlet at 1m 50 to 1m 60; › For Tunnel Twin this is 1 m.

Winch motors & Fans

FansIt’s important that the fi rst 30% can be stepless adjustable. This can be done by switching the small fans on and off or with a frequency controlled group.

With young chicks less ventilation is needed. The big fans are a source of air leakage and are not well insulated. Therefore we advise to close them with insulated doors, which are also airtight.

Winch motorsTulderhof advices to ventilate 1/3 or 1/4 and to work with a summer/winter mode. It’s best to place the winch engines in the middle of the house. To obtain a uniform valve position it is advisable to make the wire maximum 40 metres. This because temperature differences can stretch or shrink the wire. Our winch engine works with nylon belts that can be rolled twice. This prevents breakage from the drum. Also to place the engine in the middle you divide the wire length.

Air treatment

For optimization of your ventilation Tulderhof advices the Air Optimizer. Because of its special recirculation and forced air fl ow it will provide much dryer litter.

Houses <= 24 m Houses > 24 m

For poultry houses until 24 metres Tulderhof advices the X-stream I,II, III or Flash. The 4 seasons air inlet could also suffi ce when you want a plywood air inlet. When you have obstacles Flash is the only right choice.

For poultry houses wider than 24 metres Tulderhof always advises Flash. Because of its fl aps this air inlet can steer the air further into the house and bring the air where you want it.

AIR FLOW PATTERNS

Air � ow patterns with di� erent types of air inlets

1 = minimum ventilation

2 = 50% ventilation

3 = maximum ventilation

When the valve opens, the air can only pass above. This way it steers quite straight into the house. After 10 to 15% the valve opens underneath as well. The air is then defl ected downwards, creating a nice rolling effect.

Air inlet with closed bottom

Tulderhof doesn’t really advice this type of air inlets for broilers.

If you still wish this type of air inlet we can supply the Twin.

The throw (air direction) is not affected by the valve (amount of air).

This means that there are many different airfl ows possible.

Nowadays daylight is more and more an issue in broiler houses. Even special segments in the market are created for this. Also with this matter Tulderhof could be useful.

Furthermore our daylight products are KAT-worthy and can be completely darkened. This gives an additional value for your management.

› Ideal solution for mandatory daylight within 12m › Ideal for renovations › KAT-certifi ed

Energy saving?Because of the possibility to completely or partially black out the roof window, there will be less energy costs: light management.

› Excellent light diffusion › Beautiful light incursion › Energy savings › KAT-certifi ed

Flash 3300 & Flash BP

X-Stream

The Flash is an air inlet where the air direction and the amount of air are independent of each other. Advantages from Flash for broilers:

Because the air steering is independant of the position of the valve, the air enters on a different level which provides more oxygen on animal level.

› The Flash can throw to different depths › Splitting of air fl ows › Well insulated because the fl anges are inside

the poultry house

› Spring closing of self opened › 3 in 1 system possible with 1 winch motor › Because of the thickness very well insulated › Made completely from durable plastic

The Jet stream spoiler has vertically converging plates that concentrate the airfl ow 2 meters in front of the inlet. This creates a jet stream.

› The ventilation pattern is guaranteed, even when the underpressure is nog optimal

› The airfl ow to the middle is good, even when the underpressure disappears

› During periods of minimum ventilation, the air is more evenly distributed in the house

› Stepless variable

› Good and easy fl ow › Available in every size › Insulated › Robust

Tunnel Twin

› Creates a good wind chilling effect in summer

› Easy and low cost › Well guided air

Insulated doors

Fans

Tulderhof is supplier of:

› Euroemme fans: ED30, ED36, EM50 › Vostermans: Emi fans

Other fans on request.

› No air leakage › No drafts › Solid › The doors will fi t on most driven V-belts

On your left you see an infrared image of our insulated door for a fan. Result: no cold bridge.

On your right you see a fan without our insulated door, this results clearly in a cold bridge.
