Re: Best way to reach 450Psi for leak test?
We have used - as posted before - a Haskel boosterpump (air/R134a) for this.
We have an application (complet cycle of leak control, pressurizing, vacuuming, filling harvesters @ 3 units/hour) where we have to charge very fast a precise amount of R134a under a pressure of 20 bar.It's better to keep your mouth shut and give the impression that you're stupid than to open it and remove all doubt.
