| MAFA system solutions | |||||||||||||||
| MAFA has a wealth of experience of how best to store and transport pellets. MAFA have taken some examples to show how easy it is to use a Villa-silo in existing surroundings. A transport auger is flexible and easy to operate. The choice of system solution which is best suited for you depends on the brand of burner. | |||||||||||||||

| System solution 1 | |||||||||||||||
|
A simple installation in the cellar of the house where the supply of pellets is kept in an adjacent room. The transport auger is connected directly to the burner which controls the flow. Air pressure is released through the ceiling filter. The filling pipe is located on an external wall of the house to enable the easy filling of pellets from bulk deliveries. An indicator light sensor shows the delivery driver when the storage container is full.

| System solution 2 | |||||||||||||||
 |
MAFA Villa Outdoor is positioned outside the boiler room on a level base. The transport auger feeds the pellets to an ancillary hopper of the type, MAFA Mini. The ancillary hopper is automatically filled and can be seen as a backup in case pellets have not been ordered in time. Air pressure is released by way of a spring-loaded pressure hatch with hanging dust filters. The Villa-silo can be positioned up to 15 meters from the burner.

| Bulk storing of pellet fuel: | |
| Guidelines: | |
| Silo: | A completely tight silo/container. The silo must contain at least c:a 6 m3 to get the best price of pellet fuel. |
| Filling tube: | Use 102 mm tubes with a bulk connection for filling. The filling tube must be placed near where the bulk lorry unloads. If the filling tube is vertically fitted, the distance from ground to the connector must be < 1,3 - 1,5 m. At horizontal fitting the distance must be < 1,3 m. |
| Ventilation: | At least one 160 mm tube for ventilation, preferably fitted with a dust filter. |
| Road: | The same as for an oil tank lorry, that means a passable road, snow ploughed and sanded, at least 4 m free height. |
