Industrial Refrigeration


     We are an Industrial refrigeration and mechanical contractor specializing in turnkey projects worldwide from conception to completion. Our specialty is ammonia refrigeration systems, but we also can design and install systems based on almost any refrigerant. We are experienced in all types of refrigeration systems:

Flooded Ammonia Systems

Pump Recirculated Systems - using ammonia or freon as refrigerant

Phillips Recirculated Systems

Chilled Brine / Glycol Systems - using ammonia or freon as refrigerant

Direct expansion - using ammonia or freon as refrigerant

Controlled atmosphere storage facilities
   we can design and install a controlled atmosphere storage facility for almost any product from apples to onions. some of the types of controlled atmospheres that we can provide are:

  • Conventional CA, near Zero oxygen environment
  • Conventional CA combined with high Ozone, for fungal & bacterial control.

     We can design and build the equipment and piping required to maintain these environments, or we can build to your specs. examples of the CA equipment that we can supply are:

  • Nitrogen Generators
  • Membranes
  • CO2 scrubbers
  • Air Compressors
  • Air receivers
  • Nitrogen receivers
  • Power Ventilators
  • Pressure / Vacuum Safety relief valves
  • Water traps
  • Connections for Portable Nitrogen Tanks

Cold Storage Facilities

We can refrigerate your warehouse, loading dock, packing facility, packed fruit storage, segregation room, whatever you have we can design a system to keep it cool. We can also add a reheat coil to your evaporators, allowing you to maintain a constant temperature without the use of an external heating source. you can also use this type of coil to maintain a certain reletive humidity such as in a ripening room, onion storage, or a “hot box” in the beef processing industry.

Freezer storage

CWR is capable of designing for your freezing needs, from Blast cells to Ice cream rooms. We can place the air units inside your building or we can provide you with penthouse units.

Freeze Tunnels

We Have installed both spiral and inline freeze tunnels for many different applications, including corn, carrots, and other frozen vegetables.
