Model HE740 - Exhaust Unit for Pig and Poultry Houses

From

0

The HE740 exhaust unit for poultry and pig houses is the most efficient roof mounted exhaust unit available. The exhaust unit is equipped with a highly efficient fan motor that ensures high air exchange rates at very low energy consumption. In a direct comparison against leading suppliers on the market today, the HE740 exhaust unit offers at least 30 % lower energy consumption at equivalent flow rates. E.g.: 25.5W/1000 m3/h @ 17,500 m3/h.

Two versions - turning baffle or butterfly valve
The HE740 exhaust with butterfly valve completely seals off from rain, birds, insects, rodents and light when not in operation. This unit is for on/off speed control.

The HE740 with turning baffle is for speed control via a 0-10 volt signal, or on/off. This unit can be speed controlled via a frequency inverter.

The HE740 from DACS is a high efficiency and energy saving exhaust unit for livestock facilities. With a specific power input of 25,5 W / 1000 m3/hour, the exhaust unit is “best practice” in the industry and takes a significant lead over competing products. The HE740 will reduce your energy bill significantly and make you stay competitive in an ever changing and challenging market. It is simply power to your pocket!

Immense Savings
A newly developed impeller and a very efficient and aerodynamic motor together saves an immense amount of energy in comparison with traditional solutions - often more than 70 %. The reason for these savings is that DACS (as the only company in the industry) has made an application match combining motor, impeller and chimney in an extreme high performance unit - a very profitable investment.

Butterfly Valve
The advantage of using the HE740 with butterfly valve is that neither water, light, insects and birds can enter the building when the unit is not in operation. This since the butterfly valve on top of the unit seals off 100% when not in operation. The HE740 with butterfly valve should only be operated on/off.
