AC Service Equipment: Purchase & Installation

Good evening.

Since I've been looking for a climate service device for quite some time now, but unfortunately have no experience with them, I'm asking you all.

What is recommended for R134a systems? Which manufacturers are good, and what features should such a device have for everyday use in a workshop? The usage will not be very high, but it is still needed.

Should you buy used or new?
The price should not exceed €3000.
Of course, a certificate of expertise is available, but it doesn't really make much difference in the buying decision.

Thank you very much .

Hi there!

Should it be used for private or commercial purposes only?

"For personal use, I have a vacuum pump that I use to extract the refrigerant into a recovery cylinder. To fill, after evacuating with an external vacuum pump, I use a pressure gauge system and a corresponding scale to directly transfer the refrigerant from the refrigerant cylinder."

I used to work as an HVAC technician, and generally, stationary systems are only filled like this.

Sorry for the late reply.

The usage is split 50/50. The entire operation is run in a small, independent workshop with limited capacity and air conditioning. The customer base consists of approximately 60-70 vehicles. Since I haven't offered this service before, and that's well known, the demand is currently low. After a repair, I can access equipment from a partner workshop, but that process is quite cumbersome and time-consuming.
Currently, the purchase has been postponed for now.

Sure, here's the translation:

"Vg" is a German abbreviation that stands for "Viel Glück," which means "Good luck." It's often used in emails or text messages to wish someone well before an important event or task.
