NH3 Manifolds & Splitters

NH₃ manifolds and splitters are used to distribute anhydrous ammonia evenly across multiple rows of an applicator. They ensure each outlet or injection point receives a consistent flow of ammonia, improving nitrogen efficiency, preventing crop striping, and supporting safe, precise fertilizer application.

These components regulate and divide the agricultural Anhydrous Ammonia flow from a central supply line into Manifolds channel NH₃ into many individual ports—often 12, 16, or 21—to feed multiple rows. Splitters divide the flow into 2, 3, or 4 primary branches before reaching secondary distribution points or manifolds. Together, they maintain balanced pressure and ensure balanced delivery across all outlets, even at varying speeds and field conditions.

Choosing the right unit depends on several factors: Number of rows or outlets needed Required flow capacity (based on application rate and speed) System inlet size and compatibility with existing fittings Type of ammonia distribution system (vapor, liquid, or mixed phase) Preferred brand or technology, such as Impellicone or Equa-Flow If you're unsure, matching the manifold or splitter to your toolbar size and intended flow rate is the best starting point.

To ensure performance and safety, the following maintenance steps are recommended: Inspect all ports and fittings before each season for wear, corrosion, or cracking. Clean or replace orifices and internal components that may clog with debris. Check for leaks, frost buildup, or uneven row output during operation. Ensure all hoses and connections are NH₃-rated and properly tightened. Store equipment in a dry, protected area when not in use to reduce corrosion. Regular maintenance helps maintain uniform flow and extends the lifespan of your distribution components.

An Impellicone splitter is a precision-engineered flow divider developed by CDS-John Blue. It is designed to deliver an extremely uniform distribution of anhydrous ammonia across multiple outlets. Its unique internal formation compensates for pressure changes, terrain variation, and speed fluctuations and provides some of the most consistent NH₃ distribution available in agriculture. We supply the CDS-John Blue 6 Port Impellicone Splitter – IPS2-6 and the CDS-John Blue 4 Port Impellicone Splitter – IPS2-4.

No, flow dividers are designed to evenly meter and balance the ammonia flow across multiple outlets. They often include internal mechanisms, such as the Impellicone system, that actively regulate pressure differences to deliver precise, consistent distribution to each port. Whereas splitters route the NH₃ into two, three, or four branches with no internal regulating components.
