Mini-Compact Micro Sprinkler Series 866

Mini-compact model 52-866-xx is a highly efficient micro sprinkler without a bridge, designed to irrigate in an inverted position for greenhouses. It can be connected directly to a lateral vine with or without an antileak device to prevent dripping at the beginning or at the end of each irrigation cycle, keeping the entire line pressurized.

Applications:

Suits all applications in irrigation and propagation
Use in greenhouses and nurseries

Details Technical Data Part Numbers

Features:

Excellent performance with uniform water distribution
Trouble free operation even at low pressure
Color coded specially designed nozzle with backup filter
Firm compact construction without a bridge gives a complete 360° circle
Modular design allows for wide range of interchangeable components
Nozzle has a small backup filter for protection against penetration of dirt
Made of durable materials ensuring resistance to most chemicals and fertilizers for long-lived trouble free operation

Benefits:

Allows a large number of micro sprinklers to operate at the same time due to lower flow rate
Uniform growth of root system due to optimal ratio of water in the soil

HIGH UNIFORM BENCH CROP WATERING USING MODEL 52-866-XX

The tables below represent recommendations and solutions to achieve a high level of uniformity within a specific area. This spacing will achieve the best results with high coverage and uniformity, and can also achieve a lower system cost with higher efficiency.

Step 1: Select the microsprinkler flow and application rate
Step 2: Select the bench width
Step 3: Select the microsprinkler spacing

Based on this selection you can determine the application rate in inches per hour
