Atlas Copco 1614866408 Oil Cooler

Description

The 1614866408 is the oil cooler Atlas Copco fits to the water-cooled oil circuit of the GA 315, GA 355, GA 400, GA 450 and GA 500 W rotary screw compressors. The official parts record names the part OIL COOLER and lists it with a quantity of two, so a renewal is booked as a pair rather than a single unit. The 1614866408 is the exchanger that brings the lubricant back to its working temperature before the oil returns to the compression element.

What the 1614866408 does in the oil circuit

In an oil-injected screw package the lubricant seals the rotor clearance, carries heat away from the compression chamber, and lubricates the bearings and the element. The 1614866408 removes that heat as the oil flows through the exchanger, handing it to the cooling water on the far side of the tube walls. The oil that returns to the machine stays inside the temperature band the GA 315–500 W was engineered around, which is what keeps the package steady through a long loaded shift.

Which compressors use the 1614866408

The 1614866408 fits the water-cooled variants of the large GA range — the GA 315 W, GA 355 W, GA 400 W, GA 450 W and GA 500 W. The parts list for the serial settles which exchanger is fitted where, so the fitment is confirmed against the model and serial rather than guessed from the family name. Where the machine is the air-cooled version, a different cooler is fitted, which is why the “(W)” water-cooled marking on the package matters when the order is placed.

The tube-cooler package on the GA(W)

The GA(W) tube-cooler assembly groups the thermal exchangers of the package into one record. Alongside the 1614866408 the list carries the aftercooler 1614267708, a second oil cooler 1614866508, the supports, bolts, washers, nuts, plates, O-rings and the hose assemblies that connect the units. Each oil cooler in the list carries a quantity of two, so the 1614866408 is confirmed as a pair against that record.

Shell-and-tube design confirmed by the nameplate

The nameplate on the unit reads HEAT EXCHANGER and sets the part apart as a shell-and-tube oil cooler, with fluid on a tube side and a shell side kept apart by the exchanger walls. The marked type is YL8.59B-00 and the built date on the reviewed plate reads 2020.03, which ties the unit to the production run of the GA(W) coolers. The 1614866408 arrives as one exchanger with its end tanks, ports and mounting points in the positions the package was built with.

Nameplate pressure ratings

The nameplate states the design and test pressures for both sides of the exchanger. The tube side is rated for a design pressure of 1.0 MPa and a test pressure of 1.5 MPa, while the shell side is rated for a design pressure of 1.5 MPa and a test pressure of 2.3 MPa. These figures describe the pressure the 1614866408 was built and proved to, and they are taken from the plate as printed, not worked out from a generic figure.

Dimensions and weight

Each 1614866408 measures 1150 mm long, 340 mm wide and 400 mm high, and the unit weighs 50 kg. The long body sits in the bay of the GA 315–500 W, and the oil lines meet the ports on the end tank without adaptation when the part specified for that position is the 1614866408. The size is what sets the handling care: the tube bundle inside is fragile and the ends are protected during transport.

Sharing the cooling-water circuit

The water-cooled GA package runs its thermal exchangers in one cooling-water circuit, and the 1614866408 pair shares that water with the aftercooler and the second oil cooler. Cooling water enters through the inlet, passes through the tube stacks of the exchangers, and leaves through the outlet, so the oil cooler is cooled by the same water that serves the rest of the circuit. Keeping the water flow correct protects the tube bundle on the 1614866408 as much as the aftercooler.

Why the oil cooler is supplied as a pair

The larger water-cooled GA compressors carry the 1614866408 as a matched pair, listed with a quantity of two in the parts record. The pair shares the oil flow so each unit runs inside its rated condition, and a renewal replaces both together to keep the circuit balanced. Ordering a single unit against a machine that runs a pair leaves the second position open, which is why the quantity on the 1614866408 is read before the order is placed.

Identifying the 1614866408

The number on the cooler reads 1614866408, and the nameplate adds the type YL8.59B-00 and the built date 2020.03 to confirm the unit. When the 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 1614866408 is the line booked against as a quantity of two, and the packed form and current package details are confirmed with the quotation.

Ordering a replacement oil cooler pair

Read the number on the cooler being replaced, which reads 1614866408 for the current version, and note the model and serial from the compressor nameplate. Send both to Seadweer and the fitment is confirmed before the order is placed, without a second round of questions. Plants that run several large machines keep the model, the serial and the cooler number together in one record per machine, which turns the next renewal into a single confirmed message.

FAQ

What is the 1614866408 used for?

The 1614866408 is the oil cooler in the water-cooled oil circuit of the Atlas Copco GA 315 W, GA 355 W, GA 400 W, GA 450 W and GA 500 W compressors. It carries the heat the oil picks up from the compression chamber to the cooling water before the oil returns to the element, so the lubricant stays inside the working temperature band.

Which compressors use this oil cooler?

The 1614866408 fits the water-cooled GA 315–500 W range. The parts list for that serial names the oil cooler built into its circuit, and the fitment is confirmed against the model and serial rather than guessed from the family name. The air-cooled versions of these machines use a different cooler, so the “(W)” marking matters at order time.

Why are two oil coolers listed?

The large water-cooled GA compressors carry the 1614866408 as a matched pair, listed with a quantity of two in the parts record. The pair shares the oil flow so each unit runs inside its rated condition, and a renewal replaces both together to keep the circuit balanced. The same package also carries a second oil cooler, 1614866508, and the aftercooler 1614267708.

What do the nameplate pressures mean?

The nameplate on the 1614866408 states the design and test pressures for the tube side and the shell side. The tube side is rated at 1.0 MPa design and 1.5 MPa test, and the shell side is rated at 1.5 MPa design and 2.3 MPa test. These are the pressures the exchanger was built and proved to, read from the plate as printed rather than inferred.

What are the dimensions and weight of each cooler?

Each 1614866408 measures 1150 mm long, 340 mm wide and 400 mm high, and the unit weighs 50 kg. The long body sits in the bay of the GA 315–500 W, and the oil lines meet the ports on the end tank without adaptation when the 1614866408 is the part specified for that position.

How do I order a replacement oil cooler pair?

Read the number on the cooler being replaced, which reads 1614866408 for the current version, and note the model and serial from the compressor nameplate. Send both to Seadweer and the fitment is confirmed before the order is placed, which keeps the renewal to a single clean message instead of a second round of questions.
