ADV® Pinnacle HIGH Performance Trays

Worldwide, ADV® Pinnacle High Performance Trays have been installed in over five thousand columns that range in inner diameter from 28" to 402" (760 mm to 10200 mm).

ADV (Floating) Valves or ADVF (Fixed) Valves are utilized based on process requirements and have been made of materials ranging from SS410S to Monel to Hastelloy based on your application.

Retrofitting existing trays with AMT's patented high performance trays have been field proven to yield up to a 40% increase in throughput at comparable unit energy cost. Likewise, equipping new grass-roots towers with AMT ADV trays may allow over 20% higher capacity or up to 17% energy savings compared the industry standard tray design.

The larger the fractionation column or distillation column diameter, the greater the advantages of the AMT ADV trays in terms of initial equipment cost, speedy field installation, ease of maintenance, and operating energy savings. However it should be noted ADV cartridge trays have been successfully installed and are operational in columns as small as 20” (500mm).


ADV® VALVE TRAY Advantages

AMT ADV Pinnacle Performance Trays consist of a combination of various design features outlined below that allow for greater tray performance compared to the industry standard design. This in combination with our decades of design expertise allows us to achieve the highest tray performance possible (i.e., capacity, efficiency, pressure drop, turn-down and run-time) for your application. When compared with typical conventional valve or sieve trays, AMT ADV Pinnacle Performance Trays offer: 

  • Up to 40% greater throughput capacity

  • Up to 15% better fractionation efficiency

  • Up to 20% lower pressure drop

  • Greater turn-down ratio

  • Resistant to fouling and longer column run time

  • Minimum modification for debottlenecking

  • Easier field installation of trays (No Welding Optional for Turn-Around)

  • Quick return on investment of de-bottlenecking cost

  • Lower initial investment for new towers


To obtain the numerous benefits of our high performance trays, AMT incorporates the following key patented design features:

advanced dispersion valves (ADV®)

Canopies are located on top of the Advanced Dispersion Valves. They create extra vapor outlets, which lead to uniform micro-dispersion of the vapor for improved vapor-liquid contact. The canopies also act as directional flow promotion devices, which help eliminate stagnant liquid pools and promote uniform liquid plug flow and froth densities across the entire bubbling area. With the feature, most fouling materials settling on the tray deck are eliminated, which leads to extended column run time.  This feature is available for both fixed and floating ADV valves.



Typically, tray panels are connected with bolting constructions which result in approximately 75 mm to 100 mm wide of inactive zones between tray panels.

These typical inactive zones on the tray decks allow liquid to by-pass (i.e., no contact with vapor) and also offer opportunity for any fouling material to settle (due to no vapor/liquid contacting action). 

Quick Installation Active Joint

AMT ADV Trays are designed with AMT’s patented Quick-Connect Active Tray Joints, which allow easy installation while also eliminating the inactive tray joints found in all other trays. As a result, the Quick-Connect Active Tray Joints: 

  • Allow more effective and evenly distributed active area for vapor/liquid contact to increase tray capacity

  • Eliminate liquid by-pass for better tray efficiency

  • Eliminate inactive zones on the tray to avoid any fouling material settling on the tray decks (extending the column run-time)

  • Help reduce typical tray installation time by 30-50%

Higher Capacity and Flexibility

Higher Capacity and Flexibility


The AMT ADV Pinnacle Performance Tray is designed with unique inlet bubble promoters to allow for froth initiation near the inlet area of the active panels. The froth initiation helps minimize the liquid gradient on the tray and promotes uniform froth distribution across the entire tray active area. This results in higher tray capacity and operating flexibility. 



The downcomer design is an integral part of an optimized and balanced tray. Several types of downcomer designs, including our patented Downcomer Distributor technology, are available for the AMT ADV Trays. With AMT's vast experience in how each downcomer type performs, AMT is able to fine tune tray performance to each application.

Maximized Efficiency

Maximized Efficiency


For a typical plant modernization (revamp) project, the typical throughput is increased by 30% and the project can be carried out during the scheduled maintenance turn-around, which is normally 2 months or less. Expedited installation time frames can be facilitated by using our experienced field installation supervisors and engineers.


the AMT ADV® Pinnacle Performance Trays allows:

  • Reuse of all existing fractionation columns

  • No need to enlarge inlet vapor nozzles

  • No need for new foundation work or reinforcement

  • No costly and time-consuming replacement of larger columns as in past practices

  • Quick return on investment of the new mass transfer equipment, usually within one year

  • Significant improvement to column performance


When to contact AMT:

  • When your process licensors inform you you need to replace existing columns

  • When the experts inform you to enlarge the inlet vapor nozzles

  • When you are told you have to have new foundation work or reinforcement

  • When you are being sold mass transfer equipment (conventional valve or sieve trays) designed in the 90’s or even 50’s

  • When they tell you to hire an army of installers

Though AMT recommends that process licensors and plant owners adapt the high performing AMT ADV Pinnacle Performance Trays for new plant construction or current process plant modernization (revamp), AMT can design and fabricate almost any conventional tray optimized with ADV tray features to fit your needs with any of the above improvements. If extremely high capacity is required, we provide ADV - MP High Capacity Trays that can increase existing or revamped column capacity and performance significantly without the need to increase column size.

With all of the added advantages it just makes sense to incorporate the state of the art AMT ADV Pinnacle Performance Tray features instead of the antiquated conventional trays for all applications; The lower initial equipment cost, speedy field installation, ease of maintenance, greater operating energy savings, and our expert support provides greater return on investment and higher performance than the leading competitors.
