Biological silage additives can only work if the bacteria reach the forage in a fit and active state!

vario cool
  • Keep mixing and application as close together as possible.
  • Cold water reduces the bacteria‘s activity and ensures that the sugar contained in the carrier will last longer.
  • Tanks integrated into the harvester may heat up due to the heat of the motor, thus reducing the product‘s effectiveness.

The solution

vario cool set: insulated tank, cool box with thermal packs, wire whisk and mixing ball
  • vario cool is a new application concept which ensures the lactic acid bacteria‘s viability.
  • Storing the pouches / bottles in a cool box protects the lactic acid bacteria from heat, as does the insulated tank with thermal packs.
  • A small mixing ball swirling inside the tank ensures that no solution settles on the bottom.
  • A sturdy wire whisk and an application schedule complete the set.

vario cool components

vario cool: 12-Volt immersion pump

12-Volt immersion pump

The 12-Volt immersion pump is to be connected to the control unit. The pump has a forced ventilation and cannot run dry (10 - 15 min).

As mechanical force may break the hose-vent connection, it should be handled with care. Make sure that the pump reaches the bottom of the tank. Do not apply tensile strain to the power cable connected to the pump as otherwise, the sealing gasket between pump and motor may be pulled out thus enabling water to penetrate the motor. On installation, mind the correct polarity of the cables, as otherwise, the pump will not draw in the silage additive. (5 metre hose included in the scope of delivery)

vario cool: pipe filter

Pipe filter

The pipe filter ensures blockage-free operation of flow meter and nozzles and should regularly be opened for cleaning (rinse with cold water).

vario cool: attached pipe filter and flow metre

Flow meter (comes in two sizes)

The flow meter comes with a display range of 3 - 24 l/h or 10 - 100 l/h. If possible, use the supplied hose clips to fix flow meter in uninterrupted sight of driver. In any case, the flow meter needs to be installed vertically (upright). We recommend calibrating the applicator once more after the installation in order to be able to adjust the application if necessary.

vario cool: control unit, attached in the driver’s cab

Electric control unit

For a very exact application, install the electric control unit between pump and power supply. The control unit switches the pump on and off and continuously adjusts the flow rate. It should be installed in the driver‘s cab (use the magnet on the back of the unit to attach it).
Voltages above 12 V may damage the unit!

vario cool: installed pick-up sensor

Pick-up sensor (opener)

The pick-up sensor ensures that the application is interrupted as soon as the pick-up is lifted (if the harvester turns or drives on a road). Includes 3 metre hose, 3 magnets, screws, flat plugs and flat bar (300 mm) for installation.

Attach the magnetic switch for the pick-up at one of the connections (see installation sketch on the upper left side of the last page). If the switch connects, it will power the pump. It will take about 5 seconds for the application to steady. The other connection should be placed in a position which is easily accessible – it is essential for the bridge (cap included in scope of delivery). If the bridge is attached, the pick-up sensor will not work and the pump will run continuously.

Magnet = power connection if pick-up is down = pump is running cap = bridge = bypassing the pick-up sensor = permanent pumping

Nozzle carrier

vario cool e: nozzle carrier
Nozzle carrier (vario cool e)

The bayonet nut on the nozzle carrier allows rapid changing from the nozzles. An integrated non-return valve keeps the applicator from dripping. When operating the pump for the first time, open the non-return valve for airing. To ensure a perfect spray pattern at all times, change the nozzles.

vario cool: nozzles metal and blue
Nozzles:
  • metal (for application rates between 4 and 8 l/h)
  • blue or orange plastic (for application rates between 8 and 17 l/h)
vario cool r: nozzle bar
Nozzle bar (vario cool r)

The nozzle bar may optionally be equipped with up to 4 nozzles. The delivery scope includes 2 blind caps which enable you to close the valve connection in order to obtain an optimum spray pattern. An integrated non-return valve keeps the applicator from dripping. When operating the pump for the first time, open the non-return valve for airing until some of the solution is dripping from the valve and no more bubbles remain in the hose.

vario cool set

vario cool: insulated tank
Insulated tank

The insulated tank protects the lactic acid bacteria from heat. It holds 19 litres, its lid is secured with elastic loops. It is individually installed on the harvester.

vario cool: mixing ball
Mixing ball

Throw the mixing ball into the tank. The constant movement of the harvester will swirl the ball in the solution, thus ensuring continuous mixing.

vario cool box with thermal packs and wire whisk
vario cool box incl. 2 thermal packs

Our vario cool box includes two thermal packs to ensure that the silage additive pouches / bottles can be transported well-cooled, thus prolonging the lactic acid bacteria’s viability. You might want to throw one of the thermal packs into the tank after mixing the silage additive solution.

A wire whisk and an application schedule

complete the set.

In order to avoid jamming of the individual components and to prevent the formation of a biofilm (slime layer containing bacteria, funghi and viruses), clean with cold water after usage!

Assembling vario cool

Install the 3 magnets opposite the magnetic switch on the pick-up. When the pick-up is down, the magnetic field makes contact and the pump runs. If a pick-up magnetic switch is connected, remove the cap with the bypassing cable loop! Please mind the correct cable connection of the immersion pump: Connect red & brown to blue and blue & black to brown!
Install the cables in such a way that they will neither get pinched nor worn through!

Usage instructions

vario cool: freeze thermal packs for 12 h

1.

On the eve of harvesting, put both thermal packs in the freezer along with the silage additive pouches (freeze for at least 12 hours).

vario cool: mix  silage additive

2.

Before starting to chop, mix silage additive with cold water (e. g. directly in the insulated tank or a seperate container).

vario cool: insulated tank with thermal pack and mixing ball

Add mixing ball and a thermal pack to the tank.

Fill to the necessary amount of water.

Close the tank lid and secure with elastic loops, attach tank to harvester and you’re set!

3.

If required, put the remaining silage additive pouches, the second thermal pack and the wire whisk into the vario cool box and take along to the field for later use (don’t forget a canister of water).

4.

The second thermal pack in the vario cool box will keep the remaining pouches cool until they are needed.
