Introduction
With the advanced technology of the ATH AC134 eco the use in all air conditioners installed in cars, trucks and
industrial vehicles with R134a refrigerant is extremely easy. It is an easy-to-use and reliable air conditioner. The
processor-controlled AC134 eco enables the management of all functions via electronic scales, have electronically
controlled solenoid valves (measured values in weight or minutes and help messages of the selected cycles), via a
control panel with pressure gauges and a LCD display.
The connection of the AC134 eco with an A/C system allows recovering and recycling the refrigerant that is returned
to the system after evacuating.
The amount of oil that was taken during the recovery of the refrigerant of the A/C system can be measured and
subsequently refilled.
The AC134 eco is equipped with a two-stage high vacuum pump and a pressure measurement group (gauge); this
pressure measurement group let you see continuously the ongoing operations. The pressure of the refrigerant tank
is monitored and regulated electronically.
The tightness-test in the air-conditioning system is performed by the pressure gauge and the LCD display
program of the plant itself.
The AC134 eco is equipped with special connectors to avoid the risk of contamination with other units which are using
R12 as refrigerant.
