Atlas Copco 1614866108 Oil Cooler

Description

The 1614866108 is the oil cooler Atlas Copco fits to the water-cooled oil circuit of the GA 90 W and GA 110 W rotary screw compressors.

The official parts record names the part OIL COOLER, and the unit is the dedicated heat exchanger that brings the lubricant back to its working temperature before the oil returns to the compression circuit. The 1614866108 is the oil cooler listed for this position in the GA 90–110 W cooler package, and a workshop renews it as one complete exchanger against the compressor it belongs to.

In an oil-injected screw compressor the oil seals the rotor clearance, removes heat from the compression chamber, and lubricates the bearings and the element.

The 1614866108 takes the heat out of that oil as the oil passes through the cooler, where the heat is given up to the cooling water on the other side of the exchanger walls and the oil that returns to the machine stays inside the band the package was designed around. The 1614866108 is what keeps the lubricant at the temperature the GA 90 W and GA 110 W were engineered to run at through a long loaded shift.

The cooler is ordered as one part number against the compressor it is fitted to. The GA 90–110 W parts list names the 1614866108 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 1614866108 is matched against that record before the order is placed.

What the Oil Cooler Does in the Water-Cooled GA Circuit

Hot oil leaves the compressor and passes through the 1614866108 on its way back to the element. The water-cooled design moves the heat of the oil circuit into a cooling water flow that carries it away from the machine, so the oil that leaves the cooler is cool enough to seal, lubricate and carry the next round of compression heat. The 1614866108 is the component that holds the oil temperature inside the band the package was designed around.

The working temperature of the oil is the reason this part exists.

When the 1614866108 is doing its job, the oil entering the element stays inside the working band and the package runs steady under load. A cooler that has lost capacity shows up first as an oil temperature that climbs under a familiar load, which is what puts the 1614866108 on the maintenance plan.

The Cooling System the Oil Cooler Belongs To

The water-cooled GA package carries two heat exchangers in one cooling-water circuit: the aftercooler that cools the compressed air, and the oil cooler that cools the lubricant.

On the GA 90 W and GA 110 W the aftercooler is the 1614663200 and the oil cooler is the 1614866108, and both sit in the same water circuit. The cooling water enters through the inlet pipe, passes through the tube stacks of the aftercooler and the 1614866108, and leaves through the outlet pipe, so the oil cooler is cooled by the same water that serves the rest of the package.

The Water Circuit Through the Tube Stacks

The 1614866108 is built as a tube-stack oil cooler for the water-cooled GA 90 W and GA 110 W, with the oil running through its own passages while the cooling water runs through the tube stacks next to them. The two fluids stay in separate circuits across the exchanger walls, and the heat crosses from the oil to the water without the fluids mixing. The 1614866108 is supplied as one exchanger with its ports and mounting points in place.

The cooler presents to the original mounts without adaptation. The 1614866108 is the part the GA 90–110 W package was built with, so the oil lines meet the ports on the unit as the machine was designed, and a renewal is a straight swap on the planned stop rather than a modified fitment.

How the Oil Temperature Is Controlled

The water-cooled GA oil circuit uses a thermostat bypass valve that regulates how much oil reaches the cooler. While the oil is cold the valve sends most of the flow around the 1614866108 so the machine warms up quickly, and once the oil is warm the valve opens and the full flow passes through the cooler to hold the temperature steady. The 1614866108 works inside this regulated circuit rather than on its own.

The Thermostat Bypass Valve

On the water-cooled GA units the bypass valve closes the oil supply to the cooler at low oil temperature and opens it fully as the oil warms, so the lubricant is brought to its working range and then held there. The 1614866108 is sized and positioned for that regulated flow, and a renewal restores the heat rejection the circuit was designed to deliver.

Because the valve manages the temperature, the cooler itself is a passive exchanger sized for the full warm-flow condition. The 1614866108 is matched to the GA 90 W and GA 110 W oil circuit, and the parts list for the serial confirms the exact unit fitted before any order is placed.

Construction and the Unit as Supplied

Looking at the 1614866108 from the outside, the body is a purpose-built tube-stack oil cooler with its end tanks, ports and mounting flanges in the positions the GA 90 W and GA 110 W were engineered for. Nothing on the unit needs adjustment before fitting; the cooler arrives with its connections in place as one exchanger, ready to present to the original mounts in the compressor bay.

The unit is supplied new and uninstalled, still prepared for transit, so the 1614866108 reaches the workshop ready to fit. A flat, dry area with the ports covered is all the part needs between goods-in and fitment, and the body is kept clear of stacked loads so the exchanger is not stressed before it is installed.

Dimensions, Weight and Handling

The 1614866108 measures 300 × 390 × 1050 mm and weighs 48.5 kg. The 1050 mm figure is the length of the body, the run that sits in the compressor bay, while the 300 × 390 mm face is the surface to protect while the unit moves through the workshop.

At 48.5 kg the cooler is a two-person lift with normal workshop handling, and the rectangular body needs a level surface rather than a narrow shelf. A flat, dry area with the ports covered is all the 1614866108 needs between goods-in and fitment, and the body is kept clear of stacked loads so the exchanger is not stressed before fitting.

The dimensions are also what set the placement in the compressor package. The cooler sits in the bay the GA 90 W and GA 110 W were built with, and the oil lines meet the ports on the end tanks without adaptation when the 1614866108 is the part specified for that position.

This Oil Cooler and the Other Heat Exchangers on the Package

The GA 90–110 W parts list groups the oil cooler with the other thermal components of the package.

Alongside the 1614866108 the list carries the aftercooler 1614663200, the connecting pipes, a ball valve, O-rings and the bolts that mount the coolers, each named for its own position in the cooling and oil circuit. The parts list for the serial settles which exchanger is fitted where, so the 1614866108 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 GA 90 W or GA 110 W documented against its serial is the machine the 1614866108 belongs to, and the fitment is confirmed in one pass before the order is placed.

Application Across the GA 90–110 W Range

The 1614866108 is the oil cooler for the water-cooled GA 90 W and GA 110 W compressors. The same GA parts family spans the GA 90 through GA 160 and their W variants, but the larger water-cooled GA 132 W and GA 160 W use a different oil cooler (1621485008, supplied as two units), so the 1614866108 is confirmed against the model and serial rather than assumed across the whole range.

Recording the model, the serial and the cooler number together 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 oil cooler built into its circuit. The 1614866108 is the line booked against, and the packed form and current package details are confirmed with the quotation.

When the Oil 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 a joint, damage to the body, or a restriction that shows up as a pressure difference across the oil circuit are the signs that put the 1614866108 on the maintenance plan.

Keeping the cooler clean protects its capacity. On the water-cooled GA units the cooling water passes through the tube stacks of the 1614866108, and the circuit is checked as part of the routine service so the oil temperature stays inside its band. A workshop that keeps those readings in the machine file can book the 1614866108 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 1614866108 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 1614866108 for the current version, 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 W suffix confirms the water-cooled unit rather than an air-cooled 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 1614866108 into a single confirmed message, and it keeps the dimensions of the body with the part number for the next fitter.
