Technical Overview

The Howden WRV(H) 204 MK3/MK4 is part of Howden’s WRV(H) series of oil-flooded rotary twin-screw compressors used in industrial refrigeration systems, commonly found handling ammonia (NH3) and other industrial refrigerants in swept-volume/bore configurations such as the 204/110 and 204/165 variants. As an oil-flooded screw compressor, the WRV(H) relies on precisely-fitted mechanical seals, bearings, and gaskets to maintain both refrigerant containment and lubrication oil circulation, making scheduled annual inspection and seal/bearing replacement an essential part of a reliable long-term maintenance program for this compressor family.

A typical annual inspection kit for the WRV(H) 204 MK3/MK4, based on genuine-compatible parts documentation from overhaul specialists, generally includes a mechanical shaft seal kit for the input shaft (with cover O-ring), a comprehensive gasket and seal kit covering the full range of static seals used throughout the compressor body (spring washers, tab washers, bonded seals in multiple sizes, O-rings for pistons, cylinders, bearings, and rotor covers, PTFE rings and sleeves, and retaining rings), an angular contact bearing kit, and a support/journal bearing kit for the inlet and outlet ends of the rotor shafts. Seven Star LLC notes that the exact bill of materials for a specific annual inspection kit can vary depending on the compressor’s precise sub-variant and service history, and recommends confirming the exact kit contents and genuine Howden part numbers against the compressor’s nameplate details before finalizing an order.

Applications

Annual inspection and overhaul kits like this one are used by refrigeration plant maintenance teams to perform scheduled preventive maintenance on Howden WRV(H) screw compressors operating in industrial refrigeration duty — cold storage facilities, food processing plants, and process cooling systems — where unplanned compressor downtime can result in significant product loss or process disruption.

Why Seven Star LLC

Seven Star LLC works with customers across Oman and the GCC to identify the exact kit contents required for a specific WRV(H) 204 MK3/MK4 compressor’s annual service, cross-referencing the compressor’s nameplate and service history against Howden’s genuine parts catalogue before confirming a quotation, helping ensure the correct seals, bearings, and gaskets are on hand for a scheduled maintenance shutdown.

Request a Quote for ANNUAL INSPECTION KIT FOR COMPRESSOR HOWDEN WRV(H) 204 MK3-4

Contact Seven Star LLC to request a quotation for the annual inspection kit for your Howden WRV(H) 204 MK3/MK4 compressor. Our team can help confirm the exact kit contents for your specific compressor variant and support reliable delivery across Oman and the wider GCC region.

Ordering Notes

When requesting a quotation, please provide the compressor’s full nameplate details (serial number, exact sub-variant, and swept volume designation) and its service history, so Seven Star LLC can confirm the correct annual inspection kit contents against genuine Howden part numbers before your scheduled maintenance shutdown.

Preventive Maintenance Value

Performing a genuine-parts annual inspection on schedule, rather than deferring maintenance until a seal or bearing fails in service, significantly reduces the risk of unplanned refrigerant loss, oil contamination, or a catastrophic compressor failure requiring a full rebuild. Seven Star LLC helps customers across Oman and the GCC plan ahead for these scheduled kit replacements as part of a broader refrigeration plant reliability program.

Genuine Parts Assurance

Because oil-flooded screw compressors like the WRV(H) depend on precisely-toleranced seals and bearings to maintain both refrigerant containment and rotor clearances, using genuine or fully compatible replacement parts — rather than generic substitutes — is important for restoring the compressor to its original performance and reliability after a scheduled overhaul. Seven Star LLC sources kit components through verified channels and can advise on which components are safe to substitute with equivalent parts versus which require an exact genuine Howden match.

About brand

This page groups the items Seven Star LLC lists without a manufacturer brand: parts with no maker's name on the nameplate, or parts that were requested by description, drawing or part number only. The listings are mixed. They include panel voltmeters, a temperature transmitter with flameproof housing, a solenoid valve, an industrial speed sensor and an inspection kit for a screw compressor.

Buyers in Oman can send us requests of this kind for identification and sourcing.

What is listed under OEM (Unbranded)

Panel instruments: flush-mounting AC voltmeters and a digital temperature controller
Field devices: a temperature transmitter with FLP housing, a speed sensor, a solenoid valve
Machinery items: an annual inspection kit for a Howden WRV(H) 204 compressor and a mobile water filtration system
Electronics: a control card and a portable power unit

Identification comes first

With no brand to rely on, the specification is the only definition of the part. Our first step is to find out who made the original, using the part number, the markings and the equipment it came from. When the maker can be identified, we quote the item under that maker's name and type code. When it cannot, we quote strictly against the data you supplied and say so in the offer. We do not present an unidentified part as equal to a branded one.

Sending an unbranded part request: what we need

Photos of the part and of every label or stamp on it are worth more than a long description. Add the part number, the main dimensions, and the electrical data: supply voltage, signal type and measuring range. For valves and sensors give the thread or process connection and the material. For items used in a hazardous area, send the marking shown on the housing. For machinery kits, give the machine model, mark and serial number. Plants elsewhere in the GCC can send the same data.

Frequently Asked Questions

What is this inspection kit used for?

It is an annual maintenance kit assembled to service the Howden WRV(H) 204 MK3-4 rotary compressor, supplying the wear parts typically replaced during a scheduled yearly inspection.

What components does the kit typically include?

It typically includes the seals, gaskets, and bearings that are routinely replaced during an annual Howden WRV(H) 204 MK3-4 inspection, sized and specified to match OEM fitment.

Why replace these parts on an annual schedule rather than run-to-failure?

Seals, gaskets, and bearings wear gradually under continuous rotary-screw operation; replacing them on a fixed annual interval helps prevent unplanned downtime, internal leakage, and secondary damage to the compressor rotors and casing.

Is this kit compatible only with the WRV(H) 204 MK3-4 model?

It is specified for the Howden WRV(H) 204 MK3-4 compressor model; buyers with a different WRV(H) frame size or mark should confirm compatibility before ordering, as wear-part dimensions vary by model.

What industries typically use this compressor and its inspection kit?

The Howden WRV(H) 204 MK3-4 is used in industrial refrigeration systems, typically with ammonia, so the inspection kit supports maintenance programs in those heavy-duty, continuous-operation settings.
