HIGH TEMPERATURE OPERATION
- Gardner Denver AEON 9000 SP lubricating coolant will operate at
a sustained discharge temperature up to 210
°
F (99
°
C). When unusually high ambient air temperature is
encountered, lubricant life will be shortened, see
Figure 5-7
, page 54.
Air/oil under pressure will cause severe personal injury or death. Shut down
compressor, relieve system of all pressure, disconnect, lockout and tagout
power supply to the starter before removing valves, caps, plugs, fittings, bolts
and filters.
High temperature operation can cause damage to equipment or personal injury.
Do not repeatedly restart the unit after high temperature stops operation. Find
and correct the malfunction before resuming operation.
All materials used in Gardner Denver compressor units are compatible with
AEON 9000 SP Lubricating Coolant. Use caution when selecting downstream
components such as air line lubricating bowls, gaskets and valve trim.
AEON 9000 SP Synthetic Lubricant is not compatible with low nitrile Buna N or
acrylic paints. AEON 9000 SP is compatible with most air system downstream
components.
Material Safety Data Sheets (MSDS) are available for all AEON lubricants from your authorized Gardner
Denver distributor or by calling 217-222-5400.
MOISTURE IN THE OIL SYSTEM –
In environments with normal operating temperatures and pressures
and low relative humidity, the thermal mixing valve controls the oil temperature and prevents moisture
accumulation in the oil. Unusual cooling of the oil reservoir, light duty cycles, high humidity, gross
compressor over-sizing or malfunctions of the thermal mixing valve may result in moisture accumulation
which is detrimental to compressor lubrication and may cause excessive oil carryover in the lubricant or
compressor failure. Please note that the airend discharge temperature must be maintained a minimum of
10
°
F above the pressure dew point temperature in Figure 5-1, page 47
.
Failure to maintain the
discharge temperature will cause moisture formation and compressor damage. The compressor must be
observed to ensure that it is operating properly. The best method for detecting moisture is a disciplined
lubricant sampling analysis program every 2,000 hours of operation. If moisture is observed in the oil
reservoir, drain the moisture and correct the operating conditions to reduce moisture. See “Thermal
Control (Thermostatic Mixing) Valve, page 57, “Water Shutoff Valve”, page 53 and “Compressor Oil
System Check”, page 62, for additional system considerations. If moisture accumulation is observed in
the lubricant, the best option is a higher temperature mixing valve, AEON 9000TH lubricating fluid and
setting the high discharge temperature shutdown to 240
°
F (new controller software may be required), to
prevent water from forming in the oil. Please contact Technical Services in MDC for part numbers,
availability and controller software version verification (S/N required).
