\u042d\u0442\u043e\u0442 1623711800<\/strong> is the compact oil cooler Atlas Copco fits to the ZR 110 and ZR 145 oil-free compressors, where the lubrication circuit is kept small to suit a tight machine bay. On an oil-free machine the air path stays dry, and this exchanger only ever touches the sealed oil that cools the gearbox and bearings. The 1623711800<\/strong> is the cooler number quoted for that lube loop.<\/p>\n

A ZR oil-free compressor still depends on oil for its moving parts, and that oil leaves the gears and bearings hot. The 1623711800<\/strong> receives that oil, passes the heat to the cooling side, and returns it to the train at the designed temperature. It is a dedicated lube-oil unit, fully separate from the air the compressor delivers.<\/p>\n

Why a small ZR frame still needs its own oil cooler<\/h2>\n

\u042d\u0442\u043e\u0442 1623711800<\/strong> exists because even a compact oil-free compressor must shed the heat picked up by its gearbox and bearings. Those parts run inside the drive train, not in the air path, so they rely on a closed oil loop for cooling. The 1623711800<\/strong> is the exchanger that closes that loop on the 110 and 145 frames.<\/p>\n

On the larger ZR frames the same job is done by a bigger unit, but the duty is the same: keep the lubrication oil in its working band. The 1623711800<\/strong> is sized for the smaller package, so it fits the reduced bay while still moving the heat the train produces. The part is the production cooler for the position, not a resized substitute.<\/p>\n

The oil-free separation that keeps this cooler on its own loop<\/h2>\n

On the ZR range the rotors run without oil in the compression chamber, and that is what earns the Class 0 air rating. The machine still needs oil for the gearbox and bearings, and the 1623711800<\/strong> cools that sealed lubrication oil. The part works entirely on the oil loop and has no effect on the oil-free quality of the air.<\/p>\n

Because the oil never enters the air path, renewing the 1623711800<\/strong> keeps the machine oil-free on the air side while restoring the thermal control of the mechanical train. That separation is what lets a ZR hold its Class 0 air quality through a cooler change, and it is why this cooler is a dedicated lube-oil unit rather than an aftercooler.<\/p>\n

Supplied as part of a service kit<\/h2>\n

The Atlas Copco parts record lists the 1623711800<\/strong> as the lubrication oil cooler that is carried within service kit 1837036985, rather than as a standalone line on its own. Workshops planning a ZR 110<\/a> or ZR 145<\/a> service therefore receive the cooler as part of that kit, which bundles it with the other items the planned maintenance calls for. The 1623711800<\/strong> is the cooler number to quote when that kit is being prepared.<\/p>\n

Confirming the exact form against the machine serial is the safe step, because the same cooler number points to the kit that carries it. The 1623711800<\/strong> is the production cooler for the position, so a renewal restores the original cooling capacity whether it reaches the bay inside the kit or as the quoted exchange part.<\/p>\n

\u042d\u0442\u043e\u0442 1623711800<\/strong> is the lubrication oil cooler fitted to the smaller ZR oil-free frames, where the gearbox and bearing load is steady but the package is built compact.

Each 1623711800<\/strong> measures 38 cm in length, 15 cm in width and 12 cm in height, with a weight of 5.8 kg. The 38 cm length is the body of the exchanger, and the 15 \u00d7 12 cm face is the compact surface that suits the tight bay of a ZR 110 or ZR 145.

Fitment and replacement planning<\/h2>\n

Replacing the 1623711800<\/strong> starts with reading the number on the cooler being removed, then noting the model and serial from the compressor nameplate. The parts record for that serial names the lubrication oil cooler built into its circuit, so the fitment is confirmed rather than assumed. The 1623711800<\/strong> is the line booked against for the ZR 110 and ZR 145 listed above.<\/p>\n

Plants that run a pair of small oil-free machines keep the model, the serial and the cooler number together in one record per machine. That record turns the next renewal of the 1623711800<\/strong> into a single confirmed message, and it keeps the dimensions of the body with the part number for the next fitter. A clean record also avoids ordering the wrong cooler across a mixed ZR fleet.<\/p>\n

\u0427\u0430\u0441\u0442\u043e \u0437\u0430\u0434\u0430\u0432\u0430\u0435\u043c\u044b\u0435 \u0432\u043e\u043f\u0440\u043e\u0441\u044b<\/h2>\n

Why does a ZR oil-free compressor need an oil cooler at all?<\/h3>\n

The air path of a ZR stays oil-free, but the gearbox and bearings still run on oil for lubrication and timing. That oil collects heat and must be cooled, and the 1623711800<\/strong> is the exchanger that returns it to the train at the right temperature. The part works only on the sealed lube loop, never on the air.<\/p>\n

Which ZR frames use the 1623711800 oil cooler?<\/h3>\n

\u042d\u0442\u043e\u0442 1623711800<\/strong> fits the smaller ZR oil-free frames, the ZR 110 and the ZR 145. The fitment is confirmed against the machine serial rather than guessed from the family name, because the same cooler number also points to the service kit that carries it.<\/p>\n

Is the 1623711800 supplied on its own or inside a kit?<\/h3>\n

The Atlas Copco parts record lists the 1623711800<\/strong> as the cooler carried within service kit 1837036985. Confirm against your serial which form your maintenance plan uses, so the order matches the way the part is released.<\/p>\n

What are the dimensions and weight, and why so compact?<\/h3>\n

Each 1623711800<\/strong> measures 38 \u00d7 15 \u00d7 12 cm and weighs 5.8 kg. The small footprint follows the tight bay of the ZR 110 and ZR 145, where the whole lubrication circuit is built to a reduced envelope.<\/p>\n

Will renewing the cooler change the oil-free air quality?<\/h3>\n

No. The 1623711800<\/strong> cools the mechanical lubrication oil, which is fully separate from the compressed air. Renewing the cooler keeps the ZR at its Class 0 oil-free air quality.<\/p>\n

How do I confirm the 1623711800 is the right part?<\/h3>\n

Quote the number on the cooler you removed and add the model and serial from the nameplate; Seadweer checks the match before the order is placed. Where the old label has worn away, the nameplate alone settles the fitment through the parts list for that serial.<\/p>\n

Genuine supply from Seadweer<\/h2>\n

When you need a 1623711800<\/strong>, send the machine model and serial so the fitment is checked against the build record before the order is placed. Where the old label has worn away, the nameplate is enough on its own, because the parts list for the serial settles the match. The 1623711800<\/strong> ordered this way is the correct exchanger for the ZR 110 and ZR 145 it fits, with the origin and tariff recorded as supplied.<\/p>\n

A confirmed part number also keeps the service kit planning accurate, because the cooler arrives as the item the ZR 110 or ZR 145 service calls for. The 1623711800<\/strong> is the genuine Atlas Copco exchanger for the models it fits, supplied with the origin and tariff recorded exactly as the parts system lists them.<\/p>\n
