Ammonia Compressor Brands Compared: Frick, Vilter, Mycom, Sabroe, and GEA

Why Brand Matters in the Used Ammonia Compressor Market

In a market where individual compressors can run 20 to 30-plus years, brand choice is not just about the equipment in front of you — it is about what the next two decades of operation will cost. Parts ecosystem, technician familiarity, plant standardization, and resale value all hinge on which name is cast into the compressor housing.

This guide profiles the five major industrial ammonia compressor manufacturers procurement professionals encounter most often in North America and Latin America, plus three secondary brands worth knowing. Each profile covers the lineup, typical applications, parts strength, and what to look for in the surplus market.

Frick (Johnson Controls)

Frick is the dominant ammonia compressor brand in North American food and beverage processing. Now operating under Johnson Controls, the brand has been a fixture in industrial refrigeration for over a century, and the installed base across cold storage, dairy, meat, and beverage plants is substantial.

The current screw lineup centers on the RWB-II rotary screw, the RDB-II booster screw, the RWF, and the newer RXB and RXF platforms with TDSH and TDSL series rotors. High-speed reciprocating compressors complement the screw lineup at smaller capacities. The Quantum HD control panel is widely deployed on modern packages; older units commonly carry the legacy Frick Plus or Micro controllers.

Used-market notes: Frick RWB-II and RDB-II compressors are among the most common used industrial screw compressors available in North America. Parts and aftermarket support are strong through the Johnson Controls service network. For a plant already standardized on Frick, adding a matched used unit is often the most cost-effective expansion path.

Vilter (Copeland)

Vilter has 150 years of industrial refrigeration manufacturing history and is now a Copeland brand. The company is best known for single-screw compressors — a distinctive design that uses a single helical rotor meshing with two gate rotors, delivering balanced loads, low vibration, and long service life.

The current lineup includes the VSS, VSM, and VSR single-screw platforms for ammonia and CO₂, plus reciprocating compressors. The 440, 444, and 450 reciprocating series have been widely deployed historically and remain in service across the industry. Vilter has also led on transcritical and subcritical CO₂ single-screw designs as natural refrigerant adoption has accelerated.

Applications skew toward larger cold storage, beverage processing, ice rinks (Vilter reciprocating compressors are specified at multiple international speed-skating venues), and petrochemical process refrigeration. Used-market demand for Vilter single-screw compressors is consistently strong.

Mycom (Mayekawa)

Mycom is the industrial refrigeration brand of Mayekawa, a Japanese manufacturer with strong global presence including a substantial North American footprint through Mycom International Refrigeration in Texas. Mycom is the only one of the five major brands with deep roots in marine and offshore refrigeration alongside food, beverage, and industrial applications.

The reciprocating lineup includes the A and B series — both popular in smaller refrigeration plants and notable for being highly field-rebuildable, which makes them strong candidates on the used market — and the newer N series. The screw lineup covers the V series (single-screw legacy), the J series, and the SCV series with model designations like the 200 VLD (a 204mm rotor diameter single-screw). Capacities range from roughly 276 CFM to 2,259 CFM across the screw line.

Used-market notes: Mycom V and J series screw compressors are widely available, and the A and B reciprocating series are among the most rebuildable industrial recips on the market. For plants in marine, offshore, or coastal industrial applications, Mycom’s heritage in those environments is a meaningful advantage.

Sabroe (Johnson Controls)

Sabroe celebrated 125 years of industrial refrigeration manufacturing in 2024. Now part of Johnson Controls alongside Frick and York, Sabroe brings a European engineering heritage and is particularly strong in marine, offshore, and demanding industrial applications.

The reciprocating lineup is broad: 34 different sizes of single-stage compressors, 13 single-stage sizes for high-pressure applications, and eight sizes of two-stage compressors for low-temperature applications. The screw lineup includes more than 24 standard models covering 200 to 8,600 cubic meters per hour swept volume at 50 Hz.

Used-market notes: Sabroe equipment shows up across North American surplus inventories, particularly on the East Coast and Gulf Coast where marine and offshore applications drive standardization. Parts support is strong through Johnson Controls.

GEA

GEA brings together several industrial refrigeration heritages — Grasso compressors and the FES brand are both now part of the GEA portfolio. The company manufactures a broad lineup of screw and reciprocating compressors for commercial and industrial refrigeration, air-conditioning, and heat pump applications.

The current lineup includes screw compressors with models like the CompaX, a low-charge ammonia design positioned for industrial air-conditioning where minimizing refrigerant inventory is a priority. Reciprocating compressors round out the range. GEA’s aftermarket includes service kits, original spare parts, and PR-OLEO ammonia oils specifically formulated for screw and reciprocating compressor service.

Used-market notes: GEA Grasso reciprocating and screw compressors are well-represented in surplus inventories, particularly units that were originally specified by European-headquartered manufacturers operating North American plants. FES legacy units (now under GEA) are commonly available across the United States.

Brands Worth Knowing: Howden, FES, and Dunham-Bush

Three additional names show up in industrial ammonia procurement conversations and surplus inventories:

• Howden — Scottish-rooted engineering firm with twin-screw compressors widely deployed in industrial gas and refrigeration. Strong technical reputation; aftermarket support is generally available in North America.
• FES — Now part of GEA. Strong North American legacy footprint, particularly in food processing. FES compressor packages and FES Micro III control panels remain in active service across hundreds of plants.
• Dunham-Bush — Historical industrial chiller and screw compressor presence. Less common in current production but still encountered on the used market.

How to Choose Across Brands

Most procurement decisions are not abstract brand comparisons — they are constrained by the realities of an existing plant or a specific project. The framework that works:

• Plant standardization comes first. If the plant runs Frick, the operations team knows Frick, and the spare parts shelf has Frick parts on it, adding a different brand creates ongoing friction. Match the existing standard unless there’s a strong reason not to.
• Parts proximity matters. All five brands have strong North American parts ecosystems, but regional service-network coverage varies. Confirm response time on critical parts before committing to a brand the local service contractor doesn’t typically work on.
• Application fit. Marine and offshore: Mycom and Sabroe have the deepest heritage. Ice rinks and large beverage: Vilter has a particularly strong record. Food and beverage processing: Frick and GEA are exceptionally well-represented.
• Used-market availability at the capacity you need. A 350 HP Mycom screw and a 350 HP Frick screw will both do the job, but the one that’s actually sitting in a warehouse ready to ship is the one that solves the procurement problem.
