Vertical Accumulator Vessels
Vertical accumulators (VA) provide protection for a refrigeration vapor compressor by preventing occasional liquid in the suction line from entering the suction of the compressor. A means of transferring the captured liquid back to the system must be included in the system design.

Vertical accumulators with an internal pipe coil (VAC) control the accumulation of liquid inside the vessel.
  • The Frick® accumulator is designed and rated for the specified refrigerant and operating conditions
  • All nozzle connections are sized according to industry standard criteria based on the refrigerant and specified operating conditions
  • Frick® Coolware software allows custom rating of the accumulator with various refrigerants, nozzle sizing based on maximum vessel capacity or specific capacity and modification of the nozzle locations (based on limitations)
  • The accumulator vessel and components are abrasively cleaned prior to assembly assuring a clean interior and maximum adhesion of the final exterior paint system.
  • The finished vessel is pressure tested to assure the integrity of all welds, vacuum dehydrated and finally charged with a 15 psi nitrogen charge for shipment and storage.
  • The accumulator with the internal pipe coil (VAC) controls the buildup of any trapped liquid refrigerant.
 
 
  • Codes: Designed and constructed per ASME, Section VIII (latest addenda) and the Manufacturer’s Data Report registered with the National Board.
  • Design Pressure: Vessels intended for ammonia (R-717) duty are designed for a 250 psi pressure rating (300 psi on 24 inch and smaller). Alternate design pressure ratings are available.
  • Special Treatment: Post-weld heat treatment is standard for ammonia vessels.
  • Cleanliness: Pressure vessel shell material and components are abrasively cleaned prior to assembly.
  • Exterior Finish: High-quality, corrosion-resistant, long-lasting epoxy paint.
  • Quality Check: Vessels are pressure tested for integrity and leak checked.
  • Prep for Shipment: Finished vessels are vacuum dehydrated and charged with 15 psi of nitrogen for shipment and storage.
