Why Choose Stoll Liquid Inject?


Customise your Stoll Liquid-Inject System

Option 1.

Our first option is our extremely popular do it yourself kit.

This kit is unique from other systems as it allows you to use any existing equipment you may already have including tanks, pumps and rate controllers etc. It enables you to get into an extremely high quality kit for a modest price and really test out the benefits of liquids without a large capital outlay. The kit is very user friendly to operate and is easily set up on any seeder. Furthermore, it is designed to be easily upgradeable in future years if you want to add things such as rate control, auto section control or even variable rate. You may have an old computorspray or trailing sprayrig that you want to modify, or even turn one of the bins on your airseeder into a liquid tank – whatever your application this kit is flexible enough to accommodate your needs. Simply go through our step by step process and choose the components you need – it’s that easy.


Option 2

Our second option is a complete ready to bolt on module housed in our own custom designed stainless steel cabinet. The module is available in standard (STD) configuration or rate control ready (RCR). The STD configuration includes 12V controls to turn the system on/off from the cab and an adjustable throttling valve to set your operating pressure - you then drive to a set speed to ensure your application rate stays constant.

The RCR configuration has the additional features of an electric regulating valve and specially chosen electromagnetic flowmeter. This module is ready to accept an existing rate controller or GPS control / auto boom system such as GS2 or Trimble EZ-Guide 500 / EZ-Boom etc

Both modules include the following:

  • Hydraulically driven stainless steel hypro pump with cab mounted low pressure alarm.
  • Large capacity 1 ½" 316 series suction filter.
  • 1 ½" self-cleaning pressure filter.
  • 3-way panel mounted ball valve to easily change from your main tank to your flush tank.
  • High flow throttling valve with bypass agitation back to tank.
  • 12V electric plunger valve
  • Agitator tap for our dual venture agitators.
  • Panel mounted large 100mm pressure gauge
  • Distribution manifold to mount onto bar
  • All hoses and fittings to connect to tank and to distribution manifold.
  • Wiring loom with switchbox in cab (STD model only)
  • Mounting lugs to attach to seeder

In addition to the above features the RCR module also includes:

  • 12V electric regulating valve
  • Electromagnetic flowmeter which has no moving parts, internal passage of stainless steel, is highly accurate, and doesn't change its readings when measuring liquid with different viscosities any different making it the best choice when using liquid fertilizers.

We can supply the RCR model with a TeeJet 844e automatic rate controller or can set it up to use with your existing GPS / rate control equipment.

We can also supply the Trimble EZ-Guide 500 or FMX guidance system complete with EZ-Boom and rate control capabilities to do Variable rate fertilizer application.

To price up one of these kits simply choose the STD or RCR module, add your choice of standard or deluxe head manifolds and add your number of tynes.

Option 3

Capstan N-Ject LF System - The Advance System on the Market for VRT

Our third option is our exclusive N-JECT LF system from Capstan (America). Stoll's are the distributor for this product in Australia and it is the most advanced liquid fertilizer delivery system on the market. It uses advanced PWM technology to regulate the flow to the tines rather than a traditional orifice based system. The PWM valves act like a fuel injector in a car, they actually pulse very quickly to regulate the flow.

The pressure in the system remains the same but as you speed up / slow down or want to variably apply fertilizer according to a prescription map the PWM valves pulse faster or slower.

This system is excellent for those who want the ultimate in accuracy or want variable rate capabilities as you have the ability to apply product over a much wider application rate and can even vary the rate across the bar or turn individual sections on/off etc.
