and services to arise from these solutions in the near future.

There are signiﬁcant differences in servicing heavy-duty vs.
light-duty MVAC systems.

Brocx outlined
the progress of the
SAE HFTC6 Committee heavy-duty
A/C service standard. "There are
significant
differences in servicing
MVAC systems in
the heavy-duty industry. Larger capacity systems with
greater internal vol-

ume are typical. Service often needs
to be provided onsite at remote, offroad locations. Also, leak detection
and repair are major tasks, since the
larger size systems make leaks harder
to test for, isolate and repair."
"In 2016, the committee's focus
has been on identifying and promoting best service practices as well as
using proper equipment for R-134a
systems," he noted. "Examples include safety considerations; service
equipment and procedures; and refrigerant recovery, charging, lubrication,
recovery and leak detection."
"Throughout the coming year the
committee will compete a draft document (that the MACS Working Group
will help review, before sending it for
balloting at SAE. Thereafter, the committee will update the document to include alternative refrigerants for the
heavy-duty sector, such as R-1234yf.

so let us take the worry out of your air conditioning needs.

Heavy-Duty and Off-Road Sectors Address
Emissions, A/C Service
During the heavy-duty technical
training sessions, several presenters
had commented earlier on meeting the
Phase 2 requirements. They present
particular challenges for the heavyduty OEMs and raise questions. What
technology mix will achieve the significant fuel efficiency improvements
and GHG reductions in combination
with the ultra low NOx targets required? Which of those technologies
meets customers' expectations best
and brand positioning? Which solution offers most attractive total cost
of ownership?
Heavy-duty participants noted that
all areas of the powertrain and transmission, rear axle and other systems
must be considered to meet mandates.
