Each MaxCool MCX nozzle assembly is available in 1, 3, and 5 bar set pressures. Figure 5 shows the CV
versus Δp for each set pressure value.
Figure 5: MaxCool MCX CV vs Δp
The minimum ΔP for the MaxCool MCX nozzle is 2 Bar for a nozzle with a 1 Bar cracking pressure
spring, 4 Bar for a nozzle with a 3 Bar cracking pressure spring, and 6 Bar for a nozzle with a 5 Bar
cracking pressure spring. The maximum ΔP is 30 Bar.
Generally, smaller nozzles and higher cracking pressures produce smaller water droplet sizes.
