JT supplies a range of different spreaders for different use. All of them are produced in stainless steel (S316) and induction bent pipes. There are no sharp edges on the inside that can damage the pellets. The rotor is mounted in a housing with well protected bearings to ensure a long operation (rotation) between lubricating.
Today we have the following selection of spreaders:
Spreader for mounting in wire
This spreader suites cages of steel without joints. For example Procean catamaran feeding system, Bømlo Construction and MC catamaran feeding system.
The spreader can be joined with 75mm and 90mm distribution pipe from a sentral feed system and Betten-automat or a feed canon (if the air amount is big enough). This spreader is assembled in a 25mx25m Bømlo feeding system, attached to a GMT 90mm centralised feed system.

The picture (right) shows a spreader attached to a Bentten-automat with a fan. This gives an excellent spreading of the feed in the middle of the cage.
Spreaders with float

The spreader is attached to a special made float with a 1.25m diameter. It is made with a smooth surface that will not damage the fish. The rope is mounted in 4 integrated spots. The spreader is low-built and will fit almost any bird net.
Spreaders with offshore float
This spreader is made for very exposed sites. It has a very stable construction.

The offshore version is about to be mounted in a 160m plastic ring. It is very stable, a man can easily stand on one of the floats.
Motorised spreader with float
This is a spreader for the big tasks. This model is made for large cages (100-160m) which are placed on exposed sites.
The motorised spreader has a lot of advantages compared with the conventional air run spreader:
it rotates good whatever the weather
- the spreader starts when the pellets enters the distribution valve and stops when the feeding is done. It can be attached to any centralised feed system
- the length of the spread can be varied and thereby the feed can cover the whole cage
- the rotation is independent of the air supply. The blowers can then be fine tuned to ensure a gentle transportation of the feed and the operator does not have to worry about having the spreader rotating
The spreader is here mounted in a 160m plastic cage. The throw of feed is varied automatically, from a small circle step less to a large circle and then back again to a small circle. This way the whole cage is covered with feed. The spreader starts automatically when the feed arrives at the cage and stops when the feeding is finished.
The spreader can be connected to all types of centralized feed systems and can also be connected to a Betten feeder or feed cannon.
Computer controlled spreader
The motorised spreader can be delivered with a computer controlled device.
When the pellets arrive in the cage the spreader starts to move according to the settings by the operator.
All communication is wireless.
Possible ways of controlling the spreader:
Circle spreading. Suits large cages. The through of feed can be varied, up to a diameter of 35m.
--------------------------------------------------------------------------------
Set the spreader to feed up against the wind and keep the feed inside the cage. The direction is controlled by an operator using a wireless connection.
--------------------------------------------------------------------------------
Feed against the current in half a circle or a sector of the circle, change direction when the tide turns.
--------------------------------------------------------------------------------
Control the feed to land where you want it to. Steer it in a small sector, a large sector or several sectors of the circle.
