Bringing water to the world

Frequently Asked Questions (FAQ)

What features make Reinke different than other brands of mechanized irrigation?

Aside from our top-notch dealer support and service, there are a number of features that are different on our Electrogator II machine, such as:

* Single leg tower - stronger and more flexible to save you money.

* Internal flex joint - better flexibility to reduce the need for repairs.

* High strength steel - lighter and stronger for reduced wheel tracking and better durability.

* V-ring pipe flange seal - never needs to be replaced.

* Double wall tower box with a mechanical interlock system - safer and more reliable than anything else on the market.

* Pipe selection - the widest variety in the industry to give you more choice and better results for your water type.

Why does Reinke design their Electrogator II with a single tower leg?

Many people do not know that the original Electrogators built in the 1960s were designed and equipped with an angle iron, double leg tower similar to what is seen on competitive machines today. In 1975 our engineers found a better way and changed our tower design to incorporate a single channel leg design. With the recent introduction of the Electrogator II we have further improved our tower design by building our single leg tower from roll-formed material creating a "C" channel leg that improves leg strength by an additional 21 percent.

When we consider the overall design of the Reinke system it becomes more apparent why our tower is designed as it is. Reinke systems are designed to cost the least amount of money over the life of the system. Least cost takes into consideration the initial investment, cost of replacement parts and service requirements over the long life of the Reinke system. The single leg design also provides the least disturbance to taller crops as the system moves through the field.

The Reinke tower is able to flex ever so slightly below where the tower stiffener attaches. This relieves ground-induced stresses created from uneven surfaces and crop rows so that the water pipe and overhead structure do not have to absorb them. Stress cracks do not form in the structure and the overall life of the system is extended.

If enough force is induced to cause physical damage to a span, such as catching a tower with a piece of tillage equipment, the Reinke tower has the ability to absorb the damage and bend below the tower bracing, preventing significant damage to the upper structure. Repairs for a Reinke system can be a few hundred dollars compared to several thousand dollars for a competitive system in this same situation.

With the recent introduction of the Electrogator II the single tower leg was changed from a channel type leg to a "C" channel roll-formed leg. Why?

In our constant quest to become more efficient with our manufacturing process we found that a roll-formed leg made from pre-galvanized material would allow us to give our customer's systems more strength and durability without additional costs. Although the earlier channel style legs performed flawlessly, we saw an opportunity to provide producers with a better tower at a better value.

What is unique about the Reinke internal flex joint coupler?

The internal flex joint is a critical part of the strength and durability of a Reinke system. Three-axis flexibility with centerline rotation reduces span structure stress and extends boot life providing a watertight seal when compared to other types of external flex joints. This design allows the span to rotate around the pipe's longitudinal axis for more precise alignment.

Doesn't the internal flex joint create a considerable amount of water restriction for friction loss?

Because the flex joint is internal, it does create a small amount of restriction or friction loss. However it was confirmed by a Clemson University study that this friction loss is minimal. Under certain conditions, the friction loss through the Reinke flex joint will actually be less than some external flex joins under similar conditions due to the centerline rotation of this internal flex joint.

What is the Reinke "V-Ring" seal?

Reinke uses the "V-Ring" seal when joining two pipe flange joints to ensure a watertight seal. Its cross section is triangular shaped with the apex of the triangle facing away from the pipe. Reinke's pipe flanges are formed so they bolt together steel to steel with a triangular void next to the water pipe that accepts the "V-Ring" seal. Water forces the "V-Ring" seal tighter into the void casing a tight seal where the joint remains structurally stable because the forces are carried across the joint with the steel-to-steel contact. How is the "V-Ring" seal superior to the T-gasket as seen on competitive systems? The "V-Ring" seal design provides a no-maintenance feature. Properly installed, the seal is permanent. The seal is entirely encased within the flanges, preventing exposure to damaging UV rays. The seal remains soft and pliable for years. Contrast this to the competitive T-gasket where the UV rays will eventually cause the material to become brittle and crack resulting in leaks and a distorted water pattern. Replacing the T-gasket is an expensive, time-consuming process. An added benefit is that no additional friction loss is created at each pipe joint. Because the "V-Ring" does not protrude into the pipe, the joint is smooth and no additional pressure loss is created. The design of the "V-Ring" seal allows the mating pipe flanges to be bolted steel to steel. This incorporates the strength of each flange into one joint. T-gaskets do not allow steel to steel contact. The required heavier langes with the T-gasket contribute unnecessarily to the overall weight of the system.

Why is it important to have a double-wall tower box on my irrigation system?
The exclusive double-wall tower box supplied with Reinke systems creates a barrier that prevents corrosive moisture from building up inside the tower box and causing damage to the enclosed electrical components. Similar to double paned windows in a home, the double wall feature insulates the tower box and keeps the interior dry. This prolongs the life of the components and saves you unnecessary repairs.

Wouldn't it be better to have a metal tower box base instead of the molded plastic base seen on Reinke systems?

A metal tower box base is open to corrosion and the component fasteners affixed to it, resulting in higher maintenance costs. The plastic tower base allows for the effortless removal of component fasteners, requiring fewer parts and less labor, even after many years of service.

Why does the Reinke tower box design include a mechanical interlock that prevents removal of the tower box cover during operation?

This exclusive Reinke feature which is connected directly to the tower box disconnect switch will not allow anyone to remove the tower box cover without first de-energizing the machine. Once the disconnect switch is turned to the off position the system will stop, power to the tower box is disconnected and the tower box cover can be removed. This very important safety feature will protect anyone opening the tower box from being exposed to dangerous voltage levels.

How many different types of water pipe does Reinke offer?

Reinke is the only manufacturer to offer five different types of water pipe to best accommodate varying water conditions and meet the needs of your operation. The three most influential factors in determining the corrosivity of water include chloride, sulfate and pH level, along with the amount of effluent; thus dictating which type of pipe best fits your needs. As a service to producers, Reinke will analyze your water tests in order to make the most accurate water pipe recommendation to each grower.

How do you determine which type of pipe is best suited for a particular water condition?

Galvanized Steel - this type of pipe provides good protection under most conditions. However, low pH levels can be problematic for this type of pipe. A pH level at or below six will dissolve the zinc, leaving unprotected bare steel.

Chromium Nickel (CN+) Steel - this type of pipe is constructed with highly corrosion resistant steel, coated with an alkyd enamel paint that is very effective in preventing corrosion itself. CN+ pipe can be affected by low pH conditions, but the corrosion resistant properties exist in the material itself and not just in the surface coating, making it stronger and more durable than other types of pipe.

Aluminum - this type of pipe also provides good protection under most conditions, but is best used when pH levels are below seven yet no lower than five.

Stainless Steel - This type of pipe provides the best protection when pH levels are either extremely high or low.

Poly Lined - this type of pipe provides excellent cost effective protection for processed water or water that has a low pH Concentrations of certain salts, oxygen content and temperatures are some other factors that can affect corrosion rates. We recommend that producers provide Reinke with the test results of their water for evaluation before purchasing a system to ensure the best available pipe type is chosen.

Why should I buy an irrigation system with CN+ water pipe rather than galvanized steel pipe?

Along with the corrosion resistance discussed above, many producers choose CN+ because it is the strongest pipe provided by any manufacturer. CN+ has a yield strength rating of 60,000 psi. Reinke high strength galvanized pipe has a 50,000 psi yield strength rating. Therefore, Reinke's exclusive CN+ material has a higher yield strength than systems with galvanized pipe. CN+ is also a more malleable material than galvanized pipe and in areas of uneven terrain may offer an advantage. When spans are required to twist and flex over uneven ground, the CN+ is more able to absorb the flexing without fatigue. Similarly, in areas that are prone to tornadoes; the CN+ pipe often sustains less damage than galvanized pipe. What does this mean to you? It means that with Reinke, your repair costs over the life of the system will be significantly lower than with other machines.

Reinke states that it manufactures its systems with high strength steel. Why is it important to me to purchase a system that is built with these materials?

The use of high strength steel allows Reinke to build your system with the required strength and reduce the overall weight. When compared to competitive systems, a Reinke 160 foot span equipped with 6 5/8 inch water pipe actually weighs up to 1,100 pounds less than competitive machines, yet maintains superb structural strength. Reducing span weight reduces the depth of the wheel tracks and puts less stress on tower motors and wheel gearboxes, saving you time and money.

Isn't all steel high strength steel?

Standard steel is high strength compared to many other materials such as copper, brass, wood, etc. However, with the addition of alloying elements, steel can be strengthened by 40 percent or more. We use what is referred to as "high strength, low alloy steel." This type of steel gives us the additional strength plus the ability to weld and work it like standard steel. The automotive industry developed and uses this type of steel in order to make vehicles stronger yet lighter and more efficient. Reinke is the only irrigation company that is bringing you the latest in steel technology. This Reinke exclusive makes for a better irrigation system and a better irrigation value.

You have mentioned some changes to the Reinke system as a result of the recent introduction of the Electrogator II model. What other changes were made with this new design?

Along with the new improved "C" channel type tower leg, we also reduced the span crown to improve the system's stability. The tower base and legs have been lengthened to maintain appropriate crop clearance. These changes will improve system alignment. By improving the strength of the tower we were able to remove the "X" brace that existed in the previous design. The removal of this support structure improves the sprinkler device spray pattern for systems with sprinklers on shorter drops.

What does this all mean to me as a producer?

Due to our close relationship with agriculture, we know that to remain competitive we must continue our history of innovation in order to satisfy the needs of producers throughout the world for durable, cost-effective irrigation equipment. We are confident that our selection of irrigation equipment will perform as expected and continue to provide a sound return on each and every dollar invested.
