With high-precision measuring technology and
a fully automatic service procedure, the new air
conditioning unit ACS 751 from Bosch guarantees
environmentally friendly service work on air
conditioning systems for passenger cars and
The ACS 751 meets all of the requirements of
the technically demanding US standard SAE J-
2788 that covers air-conditioning units and has
the corresponding certification.
Almost all air-conditioning systems fitted in
modern vehicles still operate with the R-134a
Even with the introduction of the new R1234yf
refrigerant, it will be a number of years before any
changes are seen in the Australian market, as
vehicle manufacturers can continue to
manufacture new cars using the conventional
refrigerant until 2016.
Servicing air-conditioning systems with the
R134a refrigerant will therefore be part of the
everyday work in vehicle workshops for many years
This is why Bosch has updated its range of air
conditioning equipment for the servicing of
vehicles using the R134a refrigerant.
With their high precision measuring technology
and ease of use, the new ACS 751 servicing unit
enables repair shops to perform air-conditioning
servicing tasks in a cost-effective and
environmentally friendly manner.
There is even a status display, which can be
read from a distance, to provide ongoing
information about the test sequence using both
optical and acoustic signals to improve workshop
Recently, the introduction of the carbon tax has
led to significant price increases for the R-134a
refrigerant, meaning technicians should use it
With the ACS 751, workshop profitability is
improved by maximising recovery of the refrigerant,
allowing cost-effective refilling of the air
New air conditioning servicing units from
Bosch feature vibration-resistant precision scales
that offer the highest levels of accuracy to ensure
exact metering and filling results, thereby ensuring
that almost all of the refrigerant can be recaptured.
The increased cost of R-134a will also make
the cheaper refrigerent blends more popular and
increase the possibility of R-134a contamination
during the recovery process.
To prevent this problem Bosch has introduced
an optional refrigerant identifier to its air
conditioning product range.
The ACS 751 is also ready for the growing
number of hybrid and electric vehicles.
POE compressor oils with lower electrical
conductivity are used in the electric compressors of
hybrid and electric vehicles.
These special oils must not be mixed with the
standard oils used in the conventional belt-driven
The hybrid oil function of the ACS751 ensures
that mix-ups are impossible and that the correct
type of clean oil is fed into the vehicles
