Atlas Copco 1092571000 Oil Cooler

Descripción

El 1092571000 es el oil cooler Atlas Copco fits to the oil circuit of the XAXS 560 DD7 WUX compressor. The official parts record names the part COOLER OIL, and the unit is a brazed aluminium bar-and-plate heat exchanger that brings the lubricant back to its working temperature before the oil returns to the compression circuit. The 1092571000 is the current version of the part, and it takes the position of the cooler it replaces as one complete exchanger.

In an oil-injected compressor the oil seals the rotor clearance, removes heat from the compression chamber, and lubricates the bearings and the element. The 1092571000 takes the heat out of that oil as the oil passes through the plate passages, where the heat is given up to the cooling flow on the other side of the brazed walls and the oil that returns to the machine stays inside the band the package was designed around.

The cooler is ordered as one part number against the compressor it belongs to. The XAXS 560 DD7 WUX parts list names the 1092571000 for the oil circuit, and the parts list for the serial settles which cooler is fitted. A workshop that records the part number with the model and serial number can renew the position in one pass, and the 1092571000 is matched against that record before the order is placed.

What the Oil Cooler Does in the Circuit

Hot oil leaves the compressor and passes through the 1092571000 on its way back to the element. Inside the brazed aluminium core the oil runs through its own plate channels while the cooling flow runs through the channels next to them, and the two fluids stay in separate circuits across the plate walls. The oil that leaves the cooler is cool enough to seal, lubricate and carry the next round of compression heat, while the heat it gave up is carried away from the machine.

The working temperature of the oil is the reason this part exists. When the 1092571000 is doing its job, the oil entering the element stays inside the band the machine was designed around and the package runs steady through a long loaded shift. A cooler that has lost capacity shows up first as an oil temperature that climbs under a familiar load, which is what puts the 1092571000 on the maintenance plan.

The Heat Path Through the Plates

The photographs of the 1092571000 show a finned aluminium core with fine vertical fins across the face and smooth aluminium end tanks at the top and bottom. Small welded boss fittings sit at the corners of the end tanks as the port connections, and two yellow-capped fittings protrude from opposite ends of the core. The brazed plate construction lets the cooler move the heat of the oil circuit out of the lubricant without mixing the two fluids.

The nameplate riveted to the unit carries the identification data a fitter needs. The plate reads A.C.NO. 1092 5710 00, the machine-year serial ending …-1608001B, a design pressure of 21 bar, an internal volume of 24 l and a maximum temperature of 130 °C. Those figures are the working limits the 1092571000 was proven against before it left the maker, and they are what a workshop checks against the machine records.

Construction Visible on the Unit

Looking at the 1092571000 from the outside, the body is a rectangular brazed aluminium core with a dark finned face and a plain silver border strip along the edges. The end tanks are smooth aluminium caps with the port bosses welded at the corners, and the mounting flanges with bolt holes sit at the top corners of the tanks so the cooler presents to the original mounts without adaptation.

The bar-and-plate build is what sets the handling rule for the part. The brazed joints and the plate walls are the surfaces that keep the oil circuit separate from the cooling circuit, so the 1092571000 is kept clear of knocks and stored with nothing stacked on top of it while it waits for the planned stop. Nothing on the unit needs adjustment before fitting; the core arrives with its end tanks, ports and flanges in place as one exchanger.

The unit is supplied new and uninstalled, still banded for transit, so the 1092571000 reaches the workshop ready to present to the mounts. A flat, dry area with the ports covered is all the part needs between goods-in and fitment.

Dimensions, Weight and Handling

El 1092571000 measures 600 × 300 × 100 mm and weighs 72 kg. The 600 mm length is the run of the core, while the 300 × 100 mm face is the surface to protect while the unit moves through the workshop.

At 72 kg the cooler is a two-person lift with normal workshop handling, and the rectangular core needs a level surface rather than a narrow shelf. A flat, dry area with the ports covered is all the 1092571000 needs between goods-in and fitment, and the core is kept clear of stacked loads so the brazed plates are not stressed before fitting.

The dimensions are also what set the placement in the compressor package. The cooler sits in the bay the XAXS 560 DD7 WUX was built with, and the oil lines meet the ports on the end tanks without adaptation when the 1092571000 is the part specified for that position.

This Cooler and the Other Heat Exchangers on the Machine

The XAXS 560 DD7 WUX parts list groups the oil cooler with the other thermal components of the package. Alongside the 1092571000 the list carries a water cooler 1092571100, an intercooler 1626107101 and a restrictor 1626141201, each named for its own position in the cooling and restriction circuit. The parts list for the serial settles which exchanger is fitted where, so the 1092571000 is confirmed against that record rather than guessed from the family name.

Because the oil cooler is one item among several on the machine, the confirmation step reads the model and serial from the compressor rather than assuming the cooler from the model alone. A XAXS 560 DD7 WUX documented against its serial is the machine the 1092571000 belongs to, and the fitment is confirmed in one pass before the order is placed.

The 1092571000 Replaces the 1092309900

El 1092571000 is the current version of the oil cooler, and it supersedes the earlier 1092309900. The older number was supplied from a BE origin, while the current 1092571000 is supplied from a CN origin, and the two share the same fitted position in the oil circuit. A workshop reading the worn label on the old unit can quote either number, and the parts desk confirms the current 1092571000 as the replacement before the order is placed.

Recording both numbers with the model and serial keeps the renewal clean. When the old label has faded, the machine nameplate and the serial are enough on their own, because the parts list for that serial names the current cooler built into the oil circuit. The 1092571000 is the line booked against, and the packed form and current package details are confirmed with the quotation.

When the Cooler Is Renewed

A cooler is renewed on condition rather than on the calendar. Oil temperature that rises under a load the machine used to carry, a visible leak at a port or an end-tank joint, damage to the core or the plates, or a restriction that shows up as a pressure difference across the oil circuit are the signs that put the 1092571000 on the maintenance plan.

Recorded at a fixed interval, the oil temperature and the condition of the core turn that decision into a trend. A workshop that keeps those readings in the machine file can book the 1092571000 and the stop together, instead of reacting to a high-temperature trip on a loaded machine.

On the day of the change, the oil circuit is drained as required, the lines are removed from the ports with their positions noted, and the old core is lifted out of its bay. The 1092571000 is presented to the same mounts and the same lines, and the joints are sealed before the circuit is refilled. The first loaded run is watched against the oil temperature recorded for the old unit.

Identification and Ordering

Two pieces of information lock the order: the number on the cooler being replaced, which reads 1092571000 for the current version or 1092309900 for the unit it supersedes, and the model and serial number from the compressor nameplate. The serial matters because the parts list for that machine names the oil cooler built into its circuit, and the XAXS 560 DD7 WUX suffix confirms the brazed aluminium unit rather than a different exchanger.

Send both to Seadweer and the parts desk confirms the fitment in one pass, without a second round of questions. Where the old label has worn away, the machine nameplate is enough on its own, because the parts list for the serial settles the match.

Plants that run several machines keep the model, the serial and the cooler number together in one record per machine. That record is what turns the next renewal of the 1092571000 into a single confirmed message, and it keeps the dimensions of the core with the part number for the next fitter.
