The Problem
SPRING (RADIATION) FROST
This Typically occurs during the springtime when a combination of cloudless nights with little or no wind, low humidity and low temperatures generate sub-zero conditions for an extended period.

Damage from spring frosts may range from damaged buds or flowers, ruined or poor crop quality and even full vine loss.

The Solution - Overhead Strip Sprinkler systems

How Does it work?
During a radiation frost, vines are continuously sprayed with water above the canopy.
This process creates triple protection:
• Microclimate around the vines
• Release of latent heat
• Thin layer of ice that protects the inner cells of the crop.

Advantages
Compared to other sprinkler systems.
- Low flow strip sprinkler reduces pipe and pump size requirements
- Up to 50% less water usage compared to other strip frost protection systems
- Lower pumping operating cost
- Lower labour and machinery operating costs
- Automatic temperature activated control
