I've been trying to work out a way to set up an I/c water spray for the up coming summer...

I had these considerations in mind:
Fully automated system
boost activated
variable run on time after switching event (boost)
Fine mist from the system/ limited water supply (approx 10 litre tank)

I've come up with the following:

Timer/ switching:
Jaycar Special function timer Kit# KC5379 cost $40



This kit features a variable duty cycle, 8 amp on-board relay and a variable switch on voltage user settable 0-5 volts <- the last part is the important bit!

Water delivery System:

The pump I'll be using is a medium pressure (30 psi) fuel supply pump......

Before anyone asks.........YES, DC motors work when submerged in water!

The actual pump I'm using is out of a Navara D40 diesel (in tank lift pump).

Cost $0 (pressure too low - replaced under warranty at work)



Nozzles:

Being a cheap skate...... I'll be using a pair of garden spec micro spray nozzles.

Cost $5!

Uber hi-tech metal ones
