Frequently asked questions about Vilter

What is Vilter known for?

For more than 150 years, Vilter has helped industrial facilities maximize uptime with dependable compression solutions for refrigeration, gas compression and industrial heat pump applications.

What industries does Vilter serve?

Vilter serves industries that demand rugged, continuous-duty compression, including industrial refrigeration, food and beverage processing, cold storage, brewing, oil and gas, renewable natural gas and industrial heat pump applications. Any operation that depends on reliable, high-capacity compression can benefit from Vilter technology.

Key end markets include:

  • Cold storage and warehousing: Large-scale ammonia refrigeration systems for temperature-controlled facilities
  • Food and beverage processing: Compression solutions for meat packing, dairy, brewing and produce handling
  • Oil and gas: Compression for natural gas treatment, vapor recovery and wellhead applications
  • Renewable energy: Systems designed for biogas and landfills
What types of compressors does Vilter manufacture?

Vilter manufactures three primary compressor platforms—single screw, reciprocating and twin screw—each engineered to meet different industrial refrigeration and gas compression requirements. Whether the priority is maximum uptime, low-temperature performance or application flexibility, Vilter offers a solution designed to match the operating demands of your facility.

  • Single screw compressors (VSS/VSM/VSH Series): Designed for exceptional reliability, balanced internal forces reduce wear on critical components to help maximize uptime, extend equipment life and improve part-load efficiency.
  • Reciprocating compressors (VMC Series): Ideal for low-temperature industrial refrigeration applications where precise capacity control and dependable performance are essential.
  • Twin screw compressors: Well-suited for high-capacity industrial refrigeration and gas compression applications that require robust performance across a broad range of operating conditions.

All three platforms are available as standalone compressors or complete packaged systems with integrated controls and supporting components, allowing Vilter application engineers to configure a solution tailored to your specific requirements. 

What refrigerants are compatible with Vilter systems?

Vilter compressors are compatible with a wide range of refrigerants, including ammonia (R-717), carbon dioxide (R-744), hydrofluorocarbons (HFCs) and hydrocarbon-based refrigerants. Ammonia is the primary refrigerant for Vilter's industrial refrigeration product lines, given its superior thermodynamic efficiency and zero global warming potential.
Vilter is also at the forefront of the refrigerant transition. The brand has introduced CO2 transcritical compressor technology for industrial applications, enabling facilities to shift away from high-global-warming-potential refrigerants without sacrificing system performance or capacity.

Is Vilter a part of Copeland?

Yes. Vilter is a brand within Copeland, a global leader in sustainable heating, cooling and cold chain solutions. Copeland acquired Vilter to strengthen its industrial compression portfolio, bringing Vilter's more than 150 years of compression expertise under a company with over 18,000 employees and a presence in more than 40 countries.

How do I determine if a Vilter compressor or heat pump is right for my facility?

The right Vilter solution depends on your facility's refrigerant type, suction and discharge pressure requirements, required capacity range and ambient operating conditions. The easiest way to find out is to contact Vilter.

For complex applications or new system designs, Vilter's application engineering team provides direct technical support. Key factors to evaluate include:

Operating temperature range: Low-temperature applications often favor reciprocating compressors. Mid- to high-temperature applications suit single-screw platforms

Capacity modulation needs: Vilter compressors offer continuous capacity control to match variable load profiles Refrigerant selection: System refrigerant will determine the appropriate compressor model and materials of construction

Is Vilter manufactured in the United States?

Yes. Vilter compressors are manufactured in the United States. Production is based in Cudahy, Wisconsin, several miles from Milwaukee: the same city where Peter Weisel established the original Vilter job shop in 1867. U.S.-based manufacturing supports rigorous quality control standards and enables Vilter to respond to domestic market demand with the precision and consistency its industrial customers require.

Where are the Vilter factories located?

Vilter's primary manufacturing operations are located in the Milwaukee, Wisconsin area, where the company has been producing industrial compressors for more than 150 years. The Cudahy facility serves as the center of Vilter's engineering, production and quality assurance activities.

As part of Copeland, Vilter also benefits from a broader global manufacturing and distribution network. Copeland operates facilities and service locations across the Americas, Europe, Asia Pacific and India, the Middle East and Africa, ensuring that Vilter-branded products and components are accessible to customers worldwide.

What countries does Vilter serve?

Vilter serves customers globally, with industrial refrigeration and gas compression installations across North America, South America, Europe, the Asia Pacific region and the Middle East. As part of Copeland's worldwide network, Vilter has access to distribution and service capabilities in more than 40 countries.

How do I contact Vilter?

You can contact Vilter through the Copeland website at Copeland.com/en-us/brands/vilter/contact-vilter. The page connects you with Vilter's sales, application engineering and customer service teams.
