Misting Controller Kits

The Balance Arm Misting Controller is a simple yet effective automated sprinkler/misting controller.

The unit is supplied in a kit which contains everything you need to get started. (NZ$280.00 + GST)

This includes:

  • Balance Arm Controller with Mercury Switch
  • One Solenoid Valve
  • Three Misting Nozzles
  • Power Pack

All the grower needs to do is supply their own 15mm PVC pressure pipe to tap the misting nozzles into as well as any extra misting nozzles that may be required to cover a larger area.

The nozzles need to be arranged in a 900mm x 900mm configuration for good coverage.

Alternatively the grower can just purchase the controller only (NZ$150.00 + GST) and use their own misting nozzles and solenoid valves to set up a professional misting system.

The Balance Arm controller has a sensitive gauze covered spade device which simulates the wetting and drying of a leaf.

When a misting cycle is in progress the spade surface becomes wet and tilts the mercury switch to the “Off” position.

As the spade dries out it becomes lighter it begins to rise and tips the mercury switch to the “On” position. This signals the controller to activate the solenoid valve and another misting cycle commences. The misting cycle continues until the spade device is wet and heavy enough to close the switch again.

The sensitivity of the spade is able to be adjusted to set the appropriate misting intervals.

On warm dry days there will be more misting cycles than on cooler, overcast days. This perfectly simulates the cycle of nature and results in a high quality crop of seedlings.
