Atlas Copco 1092005069 Oil Cooler

Описание

Этот 1092005069 is the water-cooled oil cooler Atlas Copco fits to the oil circuit of the G200-250W compressor. The official record names the part OIL COOLER, and the unit is the water-cooled heat exchanger that brings the lubricant back to its working temperature before it returns to the screw element. Each G200-250W carries two 1092005069 coolers in its oil circuit, and every unit supplied is a complete exchanger built to take the position of the one it replaces.

In an oil-injected screw compressor the oil seals the rotor clearance, carries heat out of the compression chamber, and lubricates the bearings and the element. The 1092005069 takes the heat out of that oil by passing it through a water-cooled core, where cooling water on the other side of the tube walls carries the heat away from the machine instead of letting it return to the element.

The cooler is ordered as one part number against the compressor it belongs to. Because the G200-250W is the water-cooled variant of the G200-250, its oil cooler is not the same unit the air-cooled machine uses, and the parts list for the serial settles which version is fitted. A workshop that records the part number with the model and serial number can renew the position in one pass, and the 1092005069 is matched against that record before the order is placed.

What the Water-Cooled Oil Cooler Does

Hot oil leaves the compressor and passes through the 1092005069 on its way back to the element. Inside the shell-and-tube core, the oil gives up its heat to the cooling water flowing on the other side of the tube walls, and the oil that returns to the machine is cool enough to seal, lubricate and carry the next round of compression heat. The water leaves the cooler warm and is returned to the plant water circuit, while the oil stays in the closed lubricant loop.

The working temperature of the oil is the reason this part exists. When the cooler is doing its job, the oil entering the element stays inside the band the machine was designed around, the thermostat routes the flow as intended, and the package discharge temperature stays steady through a long loaded shift. A 1092005069 that has lost water-side or oil-side capacity shows up first as an oil temperature that climbs under a familiar load.

The Heat Path Through the Core

The photographs of the 1092005069 show a long cylindrical shell-and-tube exchanger with cast end housings at both ends. The tube bundle is made of Cu-Ni 90/10, a copper-nickel alloy chosen for its resistance on the cooling-water side, and the shell is cast aluminium. The two fluids stay in separate circuits across the tube walls, which is what lets the cooler move the heat of a 200-250 kW compressor out of the oil and into the water.

The nameplate riveted to the shell reads HEAT EXCHANGER and carries the part number 1092005069, the serial 1404527, the type YL12.9-00 and the build date 2014.04. The same plate records the test pressure as 1.5 MPa on the tube side and 2.3 MPa on the shell side. Those figures are the working limits the unit was proven against before it left the maker.

Construction Visible on the Unit

Looking at the 1092005069 from the outside, the body is a long cylindrical shell closed by square cast end caps at each end, with bolt heads around the cap perimeters holding the assembly together. A side outlet and an inlet elbow sit on the end housings, and a small threaded port on the shell above the lower housing serves the sensor or drain position.

The cast aluminium shell and the Cu-Ni 90/10 tube bundle give the cooler its two materials, and the riveted nameplate on the mid-shell carries the identification data a fitter needs. Nothing on the 1092005069 needs adjustment before fitting; the assembly arrives with its tube bundle, end caps and ports in place as one unit.

That construction sets the handling rule for the part. The tube walls and the end-cap joints are the surfaces that keep the oil circuit separate from the water circuit, so the 1092005069 is kept clear of knocks and stored with nothing stacked on top of it while it waits for the planned stop.

Dimensions, Weight and Handling

Этот 1092005069 measures 960 × 270 × 240 mm and weighs 51 kg. The 960 mm length is the run of the shell, while the 270 × 240 mm cross-section is the face to protect while the unit moves through the workshop.

At 51 kg the cooler is a two-person lift with normal workshop handling, and the long cylindrical body needs a level surface rather than a narrow shelf. A flat, dry area with the ports covered is all the 1092005069 needs between goods-in and fitment, and the two units for one machine are kept together so the pair is never split across stops.

The length is also what sets the placement in the compressor package. The cooler sits in the bay the G200-250W was built with, and the oil and water lines meet the ports on the end caps without adaptation when the 1092005069 is the part specified for that position.

Air-Cooled and Water-Cooled Are Not the Same Cooler

The G200-250 range is built in both air-cooled and water-cooled forms, and the two versions do not share an oil cooler. The air-cooled G200-250 uses AKG coolers 1614958800 and 1614958900, while the water-cooled G200-250W uses two SERCK 1092005069 units. Ordering against the wrong version puts an air-cooled core against a water circuit, or vice versa, so the model suffix on the nameplate decides which part number is correct.

Поскольку 1092005069 is the water-cooled item only, the confirmation step reads the model and serial from the compressor rather than guessing from the family name. A G200-250 that carries the W suffix, or that is documented as water-cooled in the plant records, is the machine the 1092005069 belongs to, and the two-piece fitment is confirmed against the parts list for that serial.

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-cap joint, damage to the shell or the bundle, or a restriction that shows up as a pressure difference across the oil circuit are the signs that put the 1092005069 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 1092005069 and the stop together, instead of reacting to a high-temperature trip on a loaded machine.

On the day of the change, the oil and water circuits are 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 1092005069 is presented to the same mounts and the same lines, and the joints are sealed before the circuits are 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 1092005069, and the model and serial number from the compressor nameplate. The serial matters because the parts list for that machine names the water-cooled cooler built into its oil circuit, and the G200-250W suffix confirms the SERCK unit rather than the AKG air-cooled pair.

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 1092005069 into a single confirmed message, and it keeps the dimensions of the core with the part number for the next fitter.
