For plant engineers and maintenance managers running an Atlas Copco ZR 300-425 oil-free screw air compressor, the intercooler core is one of the components you cannot afford to source from an uncertain supplier. We supply the genuine Atlas Copco 1621700508 (=1621600608) Intercooler Core, sourced directly from Atlas Copco (Shanghai) Trading Co., Ltd.
What We See and Handle Ourselves
Every claim we make about this intercooler core is grounded in the fact that we have physically sold, packed, and shipped this exact part number to compressor operators. When a 1621700508 unit leaves our warehouse, it goes out in an export-grade wooden crate built for a 105 kg heat exchanger core measuring roughly 104 x 42 x 44 cm. That crate is not generic packaging picked off a shelf — it carries a clearly stamped IPPC/ISPM-15 fumigation mark, which is required for any wooden packaging crossing international borders, and it carries the Atlas Copco brand markings that come standard on factory-packed spare parts.
The outbound shipping label attached to every crate we send states the product name and the exact part number, so the customer can verify what they ordered against what physically arrives before the crate is even opened. We check this ourselves before dispatch: label against packing list against the part’s own stamped identification plate. In our own handling of this component, everything about its packaging, marking, and documentation is consistent with what Atlas Copco issues for a brand-new, factory-original part — not a part in generic or unmarked packaging, and not a part with mismatched or altered labeling. That consistency, checked crate after crate, is the basis of our confidence in telling customers this is authentic Atlas Copco part.
Because we handle this part ourselves rather than drop-shipping from an unknown middleman, we can also speak to lead times, crate dimensions for freight booking, and the condition the part arrives in — details that only come from repeated, direct experience moving this specific component.

Function, Failure Signs, and Replacement
What the Intercooler Core Does
The ZR 300-425 is a two-stage oil-free screw compressor: air is compressed in a low-pressure element, cooled, then compressed further in a high-pressure element before final aftercooler. Compressing air raises its temperature significantly, and hot air is less dense and harder to compress efficiently. The intercooler core sits between the two compression stages and functions as a tube-bundle heat exchanger, removing the heat generated in the first stage before the partially compressed air enters the second stage.
By dropping the air temperature before the second compression stage, the intercooler core delivers three practical benefits to the compressed air system:
- Reduces the power required for second-stage compression, since cooler air is denser and easier to compress.
- Protects downstream seals, bearings, and the high-pressure element from thermal stress and premature wear.
- Helps condense out moisture between stages, contributing to drier, more stable compressed air quality.
On a water-cooled ZR pack, compressed air passes through the tube side (or shell side, depending on design) of the core while cooling water flows through the opposite side, carrying the heat away to the plant’s cooling water circuit or a dedicated cooling tower.
Signs the Intercooler Core Needs Replacement
- Rising discharge temperature alarms on the second stage, flagged by the Elektronikon® controller.
- A widening gap between inlet and outlet air temperature readings across the cooler.
- Visible external leakage of cooling water, or water contamination showing up in the compressed air condensate.
- Reduced heat transfer efficiency confirmed during scheduled preventive maintenance inspection or overhaul.
General Replacement Procedure
- Isolate the compressor electrically and mechanically, then depressurize the airend and cooling water circuit fully before starting work.
- Drain the cooling water side and disconnect the water inlet/outlet piping and the compressed air ducting connected to the intercooler housing.
- Remove the mounting hardware securing the cooler core inside its housing and withdraw the old core, noting the orientation and any gasket or seal positions.
- Clean the housing mating surfaces, fit new gaskets or seal kits as required, and install the new 1621700508 genuine core (replace old part 1621600608) in the same orientation.
- Reconnect water and air piping, reinstate power, and run a leak and pressure test before returning the compressor to normal operating load.
This is a task best carried out by a qualified compressor technician following Atlas Copco’s official maintenance documentation and torque specifications for the ZR 300-425 series, since incorrect gasket seating or bolt torque on the cooler housing is a common cause of early leaks.
The Atlas Copco Brand Behind This Part
Atlas Copco is a Swedish industrial group with more than 150 years of engineering history and a leading global position in compressed air and vacuum technology. Its Compressor Technique business area, headquartered in Belgium, engineers and manufactures the ZR range of oil-free rotary screw compressors specifically for industries where air purity is non-negotiable — pharmaceuticals, food and beverage, electronics, and semiconductor manufacturing among them.
The ZR 300-425 platform is part of Atlas Copco’s oil-free water-cooled compressor lineup, engineered around a two-stage screw airend design paired with dedicated intercooling and aftercooling stages, and controlled by the Elektronikon® monitoring and control system that continuously tracks discharge temperatures, pressures, and service intervals. Components such as the intercooler core are designed, tested, and manufactured to Atlas Copco’s own engineering tolerances so that heat transfer performance, pressure rating, and physical fit match the original compressor specification exactly — a level of design authority that only the original manufacturer’s supply chain can guarantee.
This engineering pedigree is why compressor operators specifically request genuine Atlas Copco parts for critical heat-exchange and airend components rather than substituting a generic equivalent: the intercooler core is a precision-engineered part, not a commodity fitting.

You can cross-check the part’s own stamped identification against your packing list and purchase order before installation.
3. What is the lead time and shipping method for this part?
Because of its 105 kg weight and crated dimensions of roughly 104 x 42 x 44 cm, this part typically ships by air or sea freight depending on the customer’s location and urgency. Contact our sales team with your destination port or address for an exact lead time and freight quotation.
4. Does the intercooler core come with installation support?
Yes. Our technical team can provide the reference replacement procedure, gasket and torque guidance, and remote support during installation, drawing on our maintenance experience with the ZR 300-425 platform and its water-cooled intercooling circuit.

Ready to Order?
Unplanned downtime on a two-stage oil-free compressor is expensive, and a failing or leaking intercooler core only gets more costly to run the longer it stays in service. If your ZR 300-425 is showing rising second-stage discharge temperatures or cooling water contamination, don’t wait for a full trip alarm.
Reach out to ACD today with your compressor’s serial number, and our technical sales team will confirm stock availability for Part Number 1621700508, provide a formal quotation, and help you plan a replacement that gets your compressed air system back to full, oil-free reliability with minimal downtime.

Anonymous_buyer –
Great experience with Sekes.
We installed this intercooler core on our ZR 300 last quarter and second-stage discharge temperatures dropped right back into normal range. Packaging arrived intact with clear Atlas Copco marks, and the fit was exact. Great experience with ACD.
Shawn Eng –
Genuine Atlas Copco cooler core.
Our semiconductor cleanroom relies on stable oil-free air, so authenticity mattered a lot to us. The crate, labeling, and part all matched our PO exactly, and our technician confirmed it was a genuine Atlas Copco core before we even installed it.
Verified Buyer –
Sekes shipped fast
Replaced our aging core after a water leak was found during a routine check. ACD shipped fast, the documentation was clean, and our ZR 425 has been running steady since. Would order from them again for our food-grade air system.
