Pioneers in Ammonia Refrigeration

Since 1928, H. A. Phillips & Co. has designed and manufactured ammonia refrigeration controls for industrial refrigeration applications worldwide. The company was founded by one of the pioneers of the ammonia refrigeration industry, Harry Alexander Phillips. Harry developed numerous patents related to modulating liquid level controls, refrigerant injectors, and automatic systems to protect refrigeration compressors from liquid ammonia slop-over. We also built our name around gas pressure recirculation – a method of liquid transfer that does not require mechanical pumps. All of these products and systems remain in common use throughout the industrial refrigeration industry.


Large Vessels and Recirculation Packages
H. A. Phillips & Co. has fabricated pressure vessels and recirculation packages for industrial refrigeration since 1975. Our facility allows us to fabricate vessels up to 144” diameter and packages weighing up to 25 tons. We have the expertise to size and design vessels for all types of industrial refrigeration systems.

Top Quality Welding Processes
H. A. Phillips & Co.’s welding fabrication processes are second to none in industrial refrigeration. All of our welders are independently ASME certified and come from the highly skilled Chicago labor market. Submerged-Arc welding stations, CNC pipe cutting machines and plasma cutting burn tables provide high quality and increased efficiency in production. GMAW, FCAW, SMAW, GTAW and SAW welding processes are used depending on the application. We are proficient in welding carbon and stainless steel.

Gas Pressure or Mechanical Pump Recirculation Systems
H. A. Phillips & Co. engineers stand ready to assist with the selection of gas pressure or mechanical pump recirculation systems. Having been a pioneer in gas pressure recirculation, we remain strong proponents for this method due to its energy consumption and maintenance efficiencies. However, for those who prefer mechanical pump systems, we have the expertise to design and produce skid-mounted vertical or horizontal pump packages to suit your application.

CAD Capability
We utilize the latest modeling technology available through SolidWorks. Flat 2D drawings are created from 3D models quickly and efficiently. Drawing submission and approval are transmitted electronically for quick turnaround.

ASME Certification
H. A. Phillips & Co. maintains an ASME ‘U’ stamp for pressure vessels and a National Board ‘R’ stamp for repairs. Welders and Welder Operators are certified in accordance with Section IX of the ASME Code.

ISO 9000 Certification
H. A. Phillips & Co. has been ISO certified for over 20 years and is currently certified to the ISO 9000: 2015 standard.
