Each
compressor is given a unique number. This is stamped on the
body casting and stays with the compressor for life; it is also
recorded on all related correspondence. |
|
| |
The
compressor is then drained of oil and completely stripped down. |
| |
All
components are inspected and measured for size and tolerance.
|
| |
Components
within the manufacturer’s specified tolerance are recycled;
all others are replaced. |
| |
Valve
reeds and piston rings are discarded regardless of condition.
|
| |
Stator
windings are removed, identified with the compressor and sent
to our electrical re-wind department for testing or re-wind. |
| |
All
cast components – body, heads and end covers – are
put through a unique cleaning process. |
| |
The
compressor is then reassembled by one of our experienced personnel
with checks made at every stage. |
| |
An
electrical bench-test follows, after which the compressor is
charged with the appropriate oil. |
| |
In
our test centre, the compressor is subjected to the most stringent
volumetric tests on a special rig, and its performance –
amps, oil pressure etc – recorded on the test sheet. |
| |
The
compressor then undergoes a leak test with OFN (oxygen-free
nitrogen) before being dehydrated and evacuated in our purpose-built
oven. |
| |
It
is then given a holding charge of OFN, and spray-painted in
the manufacturer’s original colour (unless otherwise requested).
|
| |
Finally,
after a thorough inspection, the compressor is put into stock
or sent to our despatch department. |
| Every
remanufactured compressor – complete with a full service
history – is given a 12-month warranty.
Extended
warranty can also be provided (at no additional cost) for
compressors that are not going to be installed immediately
but kept in a plant room as a ‘standby’. Warranty
can be extended for an additional 12 months after which time
we would expect it to be returned to us for an oil change
and test run. A small charge is made for this service. |
