Vilter

Some Vilter compressors have been running in the same engine room for fifty years and that kind of longevity is exactly why reliable parts support matters. CAP HVAC supplies OEM-quality aftermarket parts for Vilter open-drive reciprocating compressors, serving contractors, remanufacturers and facility operators across the Americas, the UK and Europe. From the 320 and 350 series to the upcoming 440, 450 and 450 XL platforms, we stock the pistons, connecting rods, cylinder liners, valve reeds and running-gear components that keep these industrial machines in service. Every part is manufactured to OEM specifications with full dimensional and material interchangeability and every order is backed by our 12-month warranty policy. International orders ship on a delivered-at-place basis, with the customer responsible for duties, taxes and customs clearance as the importer of record.

Most in-stock parts ship from our Cleveland, Ohio warehouse within 24 to 48 hours. Lead times for non-stock or made-to-order items are confirmed at the time of quote.

About Vilter Compressors

Vilter is one of the oldest names in American refrigeration, founded more than 150 years ago in Milwaukee, where it changed industrial compression for the brewing industry. The company has been based in Cudahy, Wisconsin since 1995 and Emerson acquired Vilter in 2009. Today, Vilter operates as Copeland’s industrial business under its own brand name.

Vilter machines are known for their durability. It’s routine to find compressors forty or fifty years old still running daily in ammonia plants. That longevity is exactly why CAP HVAC exists for this brand. Plants running 320- and 350-era machines need a reliable source for precision parts long after the original sales channel has moved on and CAP HVAC manufactures to OEM specification so these machines can keep running instead of being forced into early replacement.

Vilter Model Families

320 / 350 Series – Open-Drive Reciprocating

These are industrial open-drive reciprocating compressors, used primarily for ammonia (R-717) refrigeration and historically also applied on R-22 systems. Horsepower varies by cylinder count and operating speed, so exact ratings for a given unit are best confirmed against its nameplate. These are engine-room machines, often decades old, built for continuous heavy-duty industrial service. Common parts include pistons and piston rings, connecting rod assemblies, connecting rod bearings, cylinder liners, suction and discharge valve reeds, valve springs, unloader pins and springs, suction retaining plates and complete valve assemblies.

Parts for the 440, 450 and 450 XL Vilter series are being added to our catalog soon. Contact us to confirm current availability for these models.

Common Applications and Industries

Vilter compressors are workhorses of industrial ammonia refrigeration and CAP HVAC supports the platforms that keep these plants running.

• Food processing: meat, poultry, dairy and produce plants running ammonia refrigeration systems.
• Cold storage warehousing: large-scale industrial cold storage facilities.
• Breweries: Vilter’s original market and still a strong installed base today.
• Ice plants and ice rinks: continuous-duty ammonia compression for ice production and refrigeration.

Why Source Vilter Parts From CAP HVAC

Legacy support is our specialty with Vilter. We keep very old open-drive ammonia machines running by supplying pistons, rings, valves, bearings, shaft seals and unloader components for series the OEM has deprioritized. Buyers in this space value a supplier who can identify parts from a serial number or a worn casting, not just a part number and that’s exactly the kind of technical support our team provides before quoting, which helps prevent wrong-part orders.

Every part is manufactured to OEM specifications with full dimensional and material interchangeability and certifications are available on request. In-stock parts ship same-day or next-business-day from our Cleveland warehouse, while made-to-order items typically take two to six weeks. Every order is backed by our 12-month warranty.

We are a single supplier across brands, including Carrier and Carlyle, Copeland, Bitzer, Vilter, York, Mycom, Sabroe and Grasso, giving facilities running mixed engine rooms one account instead of several.

How to Find the Right Vilter Part

1. Locate the compressor nameplate or serial number. On older machines, this may be worn or partially illegible; send us a photo and we can help identify it.
2. Note the OEM part number, if you have it, from the old part or a parts manual, for the fastest route to an exact match.
3. Send us the details: model, serial number, part numbers, or a photo of the worn part or casting. We cross-reference OEM part numbers to our aftermarket equivalents and confirm fit before quoting.
4. Receive your quote, with pricing, availability and lead time. In-stock parts typically ship within 24 to 48 hours.
