HOLSET · CUMMINS TURBO TECHNOLOGIES
Genuine, OEM and reconditioned spares for Holset & Cummins Turbo turbochargers — H1C, H2A, H3A, HX55, HX60 & HX82 cartridges, wheels, bearings & VGT — sourced beside Alang, shipped to India, UAE, Singapore & worldwide.
A TURBOCHARGING PIONEER
Holset Engineering is founded in Huddersfield, England, beginning a long specialism in turbocharging for diesel engines.
Cummins acquires Holset, pairing the turbocharger maker with one of the world’s largest diesel-engine builders.
The H and HX families grow into the workhorse range fitted across marine, generator, off-highway and industrial engines.
Holset introduces its sliding-nozzle variable-geometry turbocharger — the VGT — setting the benchmark for boost control.
The business is renamed Cummins Turbo Technologies, though the turbochargers are still known worldwide by the Holset name.
WHO IS HOLSET
Holset is one of the most recognised names in diesel turbocharging. Founded in Huddersfield, England in 1952 and acquired by Cummins in 1973, the business was renamed Cummins Turbo Technologies in 2006 — yet the turbochargers are still known the world over as Holset. Its H-series (H1C, H2A, H3A) and larger HX-series (HX55, HX60, HX82), plus the sliding-nozzle VGT it pioneered, are fitted to marine propulsion, auxiliary gensets, offshore and tug engines. Wattmare supplies spare parts across the whole range — from a single seal ring to a complete balanced cartridge.

HOLSET SERIES WE COVER

GLOSSARY
WHERE WE DELIVER
We ship Holset / Cummins turbocharger parts from Alang / Bhavnagar to UAE, Dubai, Singapore, Greece, Turkey & worldwide in 24–48 hours.
Wattmare is a specialist Holset and Cummins Turbo turbocharger spare parts supplier serving India, the UAE, Singapore and the wider global fleet. From our base in Bhavnagar — beside the Alang ship-recycling yard — we supply genuine, OEM-equivalent and reconditioned spares for the full Holset range. Whether you run a compact H1C, H2A or H3A, a high-output HX55, HX60 or HX82, or a variable-geometry Holset VGT, we hold the cartridges, wheels, bearings, seal kits and actuators you need and dispatch them worldwide in 24–48 hours.
Holset was founded in Huddersfield, England in 1952, acquired by Cummins in 1973, and renamed Cummins Turbo Technologies in 2006. In practice the parts market still uses the Holset name. The H-series (H1C, H2A, H3A) covers compact, mid-power turbocharging; the HX-series (HX55, HX60, HX82) covers high-output main-engine and large-genset duty; and the Holset VGT — the sliding-nozzle variable-geometry turbocharger the company pioneered in 1998 — remains a benchmark for boost control. We supply spares across all of them.
For a fast turnaround, a balanced CHRA cartridge drops straight into your existing housings. For a bench rebuild, we supply the compressor wheel, turbine wheel and shaft, journal and thrust bearings, seal rings and backplate individually, or as a major-repair kit. For variable-geometry units we also carry VGT actuators, nozzle rings and sliding-nozzle assemblies.
For class-critical or newbuild work, genuine Holset / Cummins Turbo parts are the safe choice. For routine planned maintenance, OEM-equivalent aftermarket parts cut cost by 30–50%. And for emergency repairs or budget overhauls — especially on older units — reconditioned parts recovered from Alang, inspected, dynamically balanced and certified to OEM tolerance, can save up to 70%. Every reconditioned cartridge ships with an inspection report, balance results, photographs and a 30-day warranty.
Bhavnagar sits beside Alang, where hundreds of vessels and gensets are dismantled every year — many fitted with Holset and Cummins Turbo units. That gives Wattmare direct access to genuine, low-hour Holset parts that are otherwise slow to source, at a fraction of new-part cost and lead time. If you are searching for a hard-to-find Holset cartridge or VGT part, this is one of the fastest sources in the world. Browse our reconditioned marine spare parts range, the wider turbocharger spare parts category, or sister brands like MAN Diesel Turbo and KBB.

FAQ
We cover the marine and high-output Holset range — the H-series H1C, H2A and H3A, and the larger HX-series HX55, HX60 and HX82 — including their HY and HE variants. Parts are available for both fixed-geometry and Holset VGT (variable geometry) versions fitted to Cummins and many other engines.
Yes — the CHRA (centre housing rotating assembly) is one of our fastest Holset lines. We supply balanced, ready-to-fit cartridges for the H1C, H2A, H3A, HX55, HX60 and HX82, as well as the individual compressor wheel, turbine wheel, shaft, bearings and seals if you prefer a bench rebuild.
Yes. Holset was founded in Huddersfield, England, acquired by Cummins in 1973, and renamed Cummins Turbo Technologies in 2006. The turbochargers are still widely known by the Holset name, and we cover both the original Holset and current Cummins Turbo part numbers.
Yes — Holset pioneered the sliding-nozzle VGT. We supply VGT actuators (electric and pneumatic), nozzle rings, sliding-nozzle assemblies, control modules and the matching cartridge for variable-geometry HX and HE units.
Reconditioned Holset parts are inspected, dimensionally measured and ship with an inspection report and photographs. Rebuilt cartridges are dynamically balanced and run-tested. Reconditioned parts are accepted by class societies (Lloyd’s Register, DNV, ABS, BV, ClassNK) on survey; genuine parts carry full certificates.
In-stock items dispatch within 24 hours from Bhavnagar. Typical air-freight transit to the UAE (Dubai, Jebel Ali, Fujairah) is 12–18 hours, Singapore 16–24 hours, Greece and Turkey 20–26, and Northern Europe 28–36.
Yes — compressor wheels, turbine wheel-and-shaft assemblies, thrust bearings, journal bearings, backplates and piston-ring seals are all stocked individually for the H1C, H2A, H3A, HX55, HX60 and HX82 so you can rebuild rather than replace the whole unit.
Genuine parts come from Holset / Cummins Turbo with full certificates. OEM-equivalent are quality aftermarket parts at 30–50% less. Reconditioned are low-hour parts recovered from Alang, inspected, balanced and certified to OEM tolerance, at up to 70% less with a 30-day warranty.
Yes — we assemble Holset major-repair and minor-repair kits to your exact model, containing the cartridge or wheel set, journal and thrust bearings, seal rings, backplate, circlips, gaskets and O-rings for a full overhaul.
Loss of boost or surging usually points to a worn cartridge, damaged compressor or turbine wheel, worn journal/thrust bearings, a sticking VGT nozzle or a failed actuator. Send us a photo and your model number and we will identify the exact Holset parts to inspect.
Send your turbocharger model and the Holset part or serial number (or a photo of the nameplate) on WhatsApp (+91 96647 18068), or use the quote form. We confirm availability and price, usually within the hour — genuine, OEM-equivalent, used or reconditioned.
