Frequently Asked Questions (FAQs) about Vilter Products

What is Vilter known for in industrial refrigeration?

Vilter is a long-established American manufacturer of compressors for industrial refrigeration, best known for its single screw compressor lines (VSG and VSSG series) and reciprocating compressors. Now part of Emerson, Vilter compressors are widely used in food processing, cold storage, ice production, beverage and chemical processing facilities, particularly in ammonia (R-717) refrigeration systems.

What types of Vilter products do you carry?

We stock an extensive range of Vilter replacement parts including gasket kits for reciprocating compressors and chillers, gate rotor blade and bearing kits for single screw compressors, shaft assemblies, bearing covers, rotor ball bearing installers, compressor oil formulated for ammonia systems, flanges, bushings, suction tees and hardware for a wide variety of Vilter compressor models.

Which Vilter compressor models are supported by your inventory?

Our inventory covers parts for Vilter VSG and VSSG single screw compressors, 325 and 326 reciprocating compressors, 357ES models, 240 and 400 series units and various Vilter chiller configurations. With over 4,493 parts in stock, we carry components spanning much of the Vilter product line. Contact our team if you need help locating a part for a specific model.

What is a gate rotor kit and when should it be replaced?

A gate rotor kit typically includes replacement blades and bearings for Vilter single screw compressors. The gate rotor is a critical wear component that meshes with the main screw rotor to compress refrigerant gas. Over time, blades and bearings wear down, reducing compressor efficiency and increasing energy consumption. Replacing the gate rotor kit during planned maintenance helps restore performance and extend the life of the compressor.

What type of oil should I use in a Vilter ammonia compressor?

Vilter offers compressor oils specifically formulated for use with ammonia (R-717) refrigeration systems. Using the correct oil is important for proper lubrication, heat transfer and long-term compressor reliability. IRPC stocks Vilter R-717 compressor oil in 5-gallon containers for convenient ordering.

Does IRPC ship Vilter parts to both Canada and the United States?

Yes. IRPC ships Vilter parts to customers across Canada and the United States. In-stock items are ready to ship quickly, helping you minimize compressor downtime and keep your refrigeration systems running on schedule.

Can I return a Vilter part if it doesn't fit my application?

IRPC offers a flexible return policy on Vilter parts. If you are unsure whether a specific part is right for your compressor before ordering, contact our team by phone, email or live chat and we will help you confirm compatibility and availability.
