With the advent of the new high-pressure blended gases, it is
necessary to understand how to correctly perform refrigerant recov-
ery to assure operator safety and prevent premature equipment
failure. Bacharach’s Institute of Technical Training offers these 10
Tips for safe and trouble-free recovery:
■
Always identify the refrigerant you are recovering. This will
minimize cross contamination and help you plan for the equipment
needed while recovering.
■
Pay attention to your hoses. Use the shortest hoses possible for
the job. Long hoses increase the recovery time. Remove all restric-
tions in the hoses. Hoses with ball valves on the ends are better
than hoses that are self-sealing. Remove schrader core valves when
possible from service ports.
■
Do not run your recovery machine with a long extension cord or
a cord of too light a gauge wire.
■
Always recover refrigerant with an in-line filter dryer.
■
Always pump liquid out of the system first; then recover the
remaining vapors. This will speed up recovery rates significantly.
■
With large amounts of refrigerant, use the liquid push-pull
recovery method. This is three times faster than recovering liquid
directly. Refer to the liquid push-pull instructions in your equip-
ment’s manual.
■
When possible recover from both the high and low side service
port on the system you are recovering from. This will speed up your
recovery rate.
■
Climatic conditions affect recovery rates. Recovery rates can be
adversely affected by either extreme hot or cold temperatures.
■
Always purchase the right recovery machine for the job. A recov-
ery machine with a lower capacity than required by the job will
wear out prematurely.
■
When recovering R410 gas, you need a recovery machine with
high pressure and temperature capabilities, able to pull the deep
vacuum necessary for complete refrigerant removal.
Looking for a winning combination of equipment to get the
job done correctly? Bacharach has the equipment you need.
THE STINGER™ – PROFESSIONAL
REFRIGERANT RECOVERY SYSTEM
Small and lightweight,
the
STINGER is a universal recovery
system, recovering all medium
and high-pressure refriger-
ants, including R-410A. It fea-
tures a revolutionary single
valve compressor driven by a powerful 8 amp. motor. The compres-
sor works together with a high performance condenser and two
cooling fans for fast recovery – even on the hottest days. And, the
STINGER’s single purge system prevents cross-contamination of
refrigerants without changing hoses.
THE INFORMANT 2™ –
DUAL PURPOSE
REFRIGERANT /
COMBUSTIBLES LEAK
DETECTOR
The first dual purpose leak
detector, The Informant 2
combines state-of-the-art,
patented sensor technology,
micro-processor controlled circuitry and a unique software design to
offer unsurpassed precision and reliability with instant leak detec-
tion. The Informant 2 features an automatic sensitivity adjustment
that allows it to find leaks quickly, even in contaminated atmos-
pheres. It detects leaks of combustible gases sensible to 50ppm. Its
two-position probe has a tapered end (0.2” diameter) to help detect
hard to reach leak sources easily. Its ergonomic design makes it easy
to hold and operate.
FYRITE PRO® – ELECTRONIC COMBUSTION ANALYZERS
The affordable Fyrite Pro
Analyzer tests and evaluates
the operating efficiency of
residential furnaces and
appliances electronically,
allowing you to service appli-
ances with greater accuracy
and efficiency. From CO-only
tests to O
2
, stack temperature
and air temperature measure-
ments – even complete com-
bustion analyzer measure-
ments such as differential
pressure and draft, as well as combustion efficiency, CO
2
and excess
air calculations – the Fyrite Pro will give you the data you need
instantly. You can even document test results via an infrared printer.
