Tulderhof Ventilation BV - Hotraco Group products

The Flash 3300 side air inlet is made of high quality plastic as standard, very well insulated and fully removable. With its completely flexible control, the Flash 3300 is the ideal side air inlet in situations where high demands are placed on air control. Consider for example barns that are wider than 20 meters. Barns containing obstacles. The Flash 3300 also directs the airflow around structural beams.

The X-Stream was born of an innovative redevelopment of the classic side air inlet by Tulderhof. The flap opens in 2 stages: first at the top to send air to the ridge. Then the flap also opens at the bottom, partially deflecting the air downward. This creates a gentle rolling effect. This specific airflow is patented by Tulderhof. This side air inlet is made of durable plastic, the inlet is thicker than normal, and it contains high-quality EPS insulation. Both factors guarantee a high insulation value.

The BL 4500 is a side air inlet with a unique V-shaped flap that creates a jet stream with more mass. This gives the incoming air a longer throw, which allows the air to warm up better. The unique V-shape of the flap of the BL 4500 side air inlet creates a jet stream with more mass. 
The BL 4500 black line side air inlet is available 2 versions: self-opening and self-closing. With the self-closing version, you have even better control over the minimum ventilation with the 1 in 3 system.

BT stands for Black line Tunnel, a tunnel inlet made of PU-foam. De BT-01 has a flange of 40 mm around. Leaving upper or bottom flanges aside, the inlets can be mounted on top of each other. Synchronisation of the inlets is easy with the fine tune screw. The BT series can be self opening or self closing. The self closing version has the big advantage of being completely closed even if the inlets are not synchronised. The force needed to open 5 inlets on top of each other is only 16 kg, only 3,2 kg per inlet. Aerodynamic design gives the BT series 8% more air flow.
