In June 2005, the Society of
Automotive Engineers (SAE) started a research program to
reduce the emissions of R-134a. The program, called I-MAC
(Improved Mobile Air Conditioning), was tasked with cost
effectively improving R-134a systems while
reducing refrigerant emissions.
The I-MAC members have pledged to design smaller systems with
fewer leak points and improve service equipment. As a result
of this program, the SAE recently approved tighter standards
for automotive A/C recovery, recycle and recharge equipment.
The new standard, SAE J-2788, requires that all service
equipment manufactured after December 31,2007, must recover
95% of the refrigerant and recharge to within 1/2 ounce.
For years, R-134a was cheap and
plentiful. Today it’s a different story- refrigerant is much
more expensive and not always available. The Robinair 34288
recovers up to 20% more refrigerant, which means it will cost
less to recharge the system. The best charge accuracy that
could be claimed by older generation service machines was +/-
1 ounce, a 3% error on a two-pound system. That same charge
accuracy on a 14-ounce system is over
twice the error (7%).
Early R-134a systems could still provide some cabin cooling
when they were 4-6 ounces (12-18%) low on refrigerant.
However, new designs are so efficient, they do not have
reserve refrigerant, and charge accuracy is critical. The
Robinair 34288 will recharge the vehicle to within 1/2 ounce
of the charge capacity, and you will avoid
the dreaded “come back”. As the shop owner, you will
realize more profits per service by recovering more
refrigerant and charging less. Refer to the ROI worksheet on
the back of this brochure to determine your actual cost
savings. The savings will be obvious.
