Automatic fertilizer injector FERTIGEST

with precise dosingwith controllerVenturi

Short description
Professional fertigation unit with scalable modular architecture, Venturi injection and precise nutrient, pH and EC control.

Detailed description
GESTIMAX is a compact solution for integrated irrigation and crop nutrition management. The unit combines an AISI 304 stainless steel frame with an integrated controller and a 5" color touchscreen for local and remote operation. Fertilizer and pH/EC regulators are injected via Venturi technology without moving parts in the suction system, reducing downtime and maintenance. A cylindrical mixing block ensures homogeneous blending of the nutrient solution before introduction to the main line.

Highlights

• Compact design with AISI 304 stainless steel construction.
• Injection capacity up to 500 l/h per line, expandable to 1000 l/h.
• Integrated controller GXF-5 S16.
• 5" color touchscreen display.
• Remote control via PC software and mobile app with GW600 router.

General specifications
The unit is equipped with a GXF-5 S16 control unit and a 5" color touchscreen for simplified operation. Injection capacity per line is up to 500 l/h, expandable to 1000 l/h. The chassis features a load-bearing structure in AISI 304 stainless steel and is designed for fertigation applications with pH and electrical conductivity (EC) control.
