The MVA Matrix Vertical Accumulator Package reduces installation time and cost compared to field fabricated units. At the heart of the package is the Matrix LLC™ (Liquid Level) Control Panel, providing total liquid level control. The MVA Matrix Vertical Accumulator Package is available in a complete range of vessel diameters from 16” to 144”, with or without internal pipe coils. Major components are maintained in factory inventory to enable fast on-time shipments.
Standard MVA catalogued models range in capacity from 24 to 5,401 tons of refrigeration for ammonia depending on the high stage suction temperature and are based on a 96oF liquid feed temperature. The MVA package is a liquid collection point for the suction line returning to the compressor(s) to prevent damage to the compressor(s). It can be arranged to drain accumulated liquid to a transfer vessel or it can boil off accumulated liquid. Boiling off accumulated liquid is accomplished by adding an internal pipe coil inside the vessel. This arrangement changes the model nomenclature from MVA to MVAC.
Alternatively, depending on the system design, the internal pipe coil can be designed for use as a sub-cooling coil to sub-cool liquid refrigerant. Surge volumes for the MVA / MVAC range from 3.9 to 430.7 cubic feet.
