MTP Matrix Transfer Package

The MTP Matrix Transfer Package represents the latest innovation in ammonia system design for liquid transfer requirements. The MTP features RVS' NEW Matrix Liquid Transfer Control (LTC) Panel and RVS' NEW Advanced Low-Probability (ALP) ammonia transfer pump by Teikoku. These are combined with RVS' MVA Matrix Vertical Accumulator Package to form the NEW MTP. The MTP provides an all-in-one, factory built, engineered solution to ammonia system liquid transfer requirements from the low pressure to the high pressure side of the system. RVS' single package system eliminates traditional combinations of multiple vessels or packages for liquid transfer, reducing charge and eliminating the need for hot gas assist. The MTP Matrix Transfer Package system with Matrix LTC is state of the art and confidently backed by RVS with an EXCLUSIVE and COMPREHENSIVE 3-YEAR WARRANTY.

Standard catalogued models range in size from 24” to 144” outside diameter in a vertical vessel orientation with capacities from 56 to 5415 tons. Capacity range is based on 95F liquid supply temperature and varies based on the suction temperature. Surge volumes range from 9 to 621.2 cubic feet.
