Notice on Using Non-Vilter Oils

CAUTION
Do not mix oils. Failure to comply may result in
damage to equipment.
NOTICE
Vilter does not approve non-Vilter oils for use with
Vilter compressors. Use of oils not specifi ed or
supplied by Vilter will void the compressor warranty.
Due to the need for adequate lubrication, Vilter rec-
ommends only the use of Vilter lubricants, designed
specifically for Vilter compressors. With extensive
research that has been performed, we are able to of-
fer per each specific application lubricating oils. Use
of oil not specified or supplied by Vilter will void the
compressor warranty.
Please contact your local Vilter representative or the
Home Office for further information.

Instrumentation Requirements

Pressure

There are four pressure transducers required to read sys-
tem pressures as listed below:
1. Suction pressure transducer (15.0 - 1000 PSIG)
measures the gas suction pressure into the compressor
housing, which provides the permissive to start at reach-
ing minimum suction pressure, and is used to detect low
suction pressure while running and in the capacity con-
trol logic.
2. Discharge pressure transducer (15 – 1000 psig)
measures the discharge pressure of the process gas in
the separator, which provides detection of high dis-
charge pressure, and may also be used for capacity con-
trol logic.
3. Oil Filter Inlet pressure transducer (15 – 1000 psig)
measures the oil pressure as it enters the oil filter canis-
ters and is used to calculate oil filter differential pressure
to provide detection of high filter differential pressure.
4. Oil Manifold pressure transducer (15 – 1000 psig)
measures the oil pressure downstream of the oil filter as
the oil is injected into the compressor, and provides de-
tection and protection against low prelube oil pressure,
and low running oil injection pressure.
Additional pressure transducers may be required and
installed by the customer for pressure readings at cus-
tomer specified points such as process gas discharge
pressure from the package boundary, cooling water
pressure to and/or from the oil cooler, etc.
