Anderson Injectors

Since their beginning many years ago, Anderson Injectors have met the needs of the small and large cailities with their outstanding American technology and extremely low maintenance and long life. A great product.

The Ratio:Feeder® Feeds: Nutrients, Acids, Bases, Chlorine, Bromine, Herbicides and More

Used extensively in Hog, Poultry, and Animal Houses

Used by Greenhouses, Containers, Golf
Courses, Turf, Landscape, and Agriculture

The Anderson Ratio-Feeder® comprises many different sizes of units. Modular design permits constructing a system for your exact needs. And you can change the configuration in the field. Change from one solution to as many as you would like. Easily! With common tools. Change back. It's easy to have just the unit you need.

The Ratio:Feeder® is a positive displacement, volume proportioning pump. Its design permits wide water flow ranges with minimal pressure loss. And lasting accuracy at all flow rates. Day to day maintenance is minimized by our design. There are NO SLIDING SEALS in the pumping mechanism. There is no metal in contact with the chemical (stainless check balls are used with fertilizers and some acids.). And there is an air gap between the chemical and the rest of the pump mechanism.

Several different series designs so you can choose the features you want or need:

• The Series J-Plus: our intermediate line
• The Series S: the original design
• Andy and Andy Jr. Series Injector Injectors

• The Ratio:Guard^TM: Ph and EC controls for the Ratio:Feeder family. Also works with many other injectors as well.

The Series J-Plus.... an intermediate design!

This newest design now offers programmable input flow constant (Bogey #) so more types of flow sensors can be utilized, turbines, jet, disc, and even paddle wheels. Single or dual output. The dual or second output can be configured separately so chemicals like acids or chlorine that require very small dosing rates will not conflict with the high nutrient feed rates. Many flow ranges available up to 2300 G.P.M. or higher.

Series J-Plus. Optional second output with one acid pumper shown.

All above models are available as "portable" models. Simply add a letter "P" to the end of the model (e.g. DD!00P). Also, each portable model is available with a "rechargeable battery" option. Simply add a letter "B" to the end of the model (e.g., DD100PB). If you order a portable unti without a battery option, it will come with a 110VAC power supply.

RATIO : GUARD^TM pH & EC CONTROLS

Ratio : Guard^TM controller is the ideal complement to your Ratio : Feeder® (or other) injector system. Monitor your EC (fertilizer level) or pH (acid level) or both with these microprocessor controller / monitors. Available models include Model P-1 (pH only) and model E-1 (EC only).

Features Common to Both Models:

• Program is permanently encoded in processor.
• User settings are retained by battery back up.
• Large visible LCD display.
• High and Low Alarm Setpoints with 10 amp. N.O. and N.C. contacts and visual indication of alarm.
• Insertion type probes - easy to remove for cleaning.
• Probe mounted signal conditioners allow long cable runs and greater immunity to interference.
• Easy programming using sealed membrane protected keypad.
• Electronic calibration of pH electrodes - No manual adjustment required.
