Windmachine ECO Model

 

THE WORLDS MOST EFFICIENT WIND MACHINE FOR FROST PROTECTION

 

The „ECO-MODEL“ was designed especially for smaller orchards and is able to protect areas up to 3,5 hectares.This technique of frost protection is based on air turbulence and recirculation of rising heat on higher air layer.
Operating on flat areas without appreciable difference in altitude and without drift of cold air the wind machines should rotate 360° (full circle rotation) to protect the maximum of area. The ability to oscillate provides efficient frost protection also in valleys or on slopes, because the cold air mass on the lower level can be moved downwards or respectively out of the valley.
The possibility to angle the fan brings more flexibility to adapt the machine to the area.

 

ALLOY FAN WITH STRAIGHTENING GUIDE VANES  MANUAL START CONTROLS

 

The machine „ECO-MODEL“ needs a setup time of 10 minutes. No building permit necessary.
This portable machine works extremely efficiently and is very quiet.  It can be towed by tractor or by car. “Tow and Blow ECO-MODEL“ is very compact and flexible. The compact construction and high operating position allows to operate in rows of two meters distance and in orchards with hail protection.

 

The „ECO-MODEL“ works with a Honda gasoline engine with 23 HP, which is directly coupled with the propeller.
The motor starts manually by key. The impeller has 8 blades. Thanks to the shroud around the fan, the efficiency is much higher than an open fan. The slim dimension of the tower avoids energy loss on the suction side of the fan. Fuel consumption is five to six liters/ hour.

 

TECHNICAL DETAILS

  • engine: gasoline engine Honda 23 HP, 2-cylinder V-motor "Industry Type" for continuous operation.
  • fan: propeller is made of aluminium casting, shroud with bell mouth suction side, vane sheets at the discharge, air speeds 20 m/s coverage up to 3,5 ha.
  • lift mechanism of the tower completely hydraulic
  • rotation mechanism of the driver by a gearbox
  • four telescoped stabilizer legs to set the machine in operation position
  • noise level: 45 db/a 300 m
  • transport by tractor or car with ball hitch trailer or draw bar eye
  • service, lubrication and fuel-filling is possible on location, with lowered position of the tower

WHAT ARE THE BIGGEST ADVANTAGES OF A PORTABLE TOW AND BLOW WIND MACHINE? 

  • the possibility to work in the same direction as the wind drift to increase the protected area (picture 1) or operating in a full rotation (picture 2)
  • no construction permit necessary
  • no external service costs necessary 
  • spare parts are available worldwide 
  • no loss of ground by a fixed construction or a foundation 
  • no installation necessary 
  • application at the favored place
  • rotation of the tower in optional direction
  • now operation costs
  • high operation safety and CE certified- portable so it can be moved to different crops requiring frost protection at different times of the year

VENTILATION, DRYING, COOLING:  The portable wind machine „Tow and Blow“ can be used for further purposes. For example for cooling or drying of fruits before harvest.
