Saiptech's Tray Technology with Reliablity & Performance 
For many years, column trays have been used in a wide range of separation processes in the petrochemical and chemical industries. Although trays have been replaced in part by random and structured packing, there are many mass transfer applications in which trays will be the preferred choice.
Trays are essentially used when:Towers are very large in diameter (Multi-pass Trays)Compounds contain solids or foulantsThere are many internal transitionsLiquid loads are highLack of experience in the serviceChemical Reaction/Absorption - use high weirs to provide greater residence time for absorption / chemical reaction.
Saiptech offers a variety of tray products which include conventional sieve, valve and bubble cap trays, and specialty trays such as dual flow trays, disc and donut and side-to-side baffle trays.
Sieve Trays--Simple Solutions
Sieve trays are a low priced type of trays where high turndown is not required. Saiptech has the capability to design and manufacture virtually any type of sieve tray. Tray hole sizes down to 3.2 mm and up to 16 mm in diameter are offered.

Bubble Cap Trays--High Turndown

Bubble cap trays, generally, have the ability to handle wide ranges of liquid and vapour flow rates satisfactory due to their leak proof properties. This advantage is exploited in special applications such as gas scrubbers where a large amount of vapour must be in direct contact with the low liquid flow.
Standard cap sizes of 80, 100 and 150 mm are available. Custom designs are also available.

Dual Flow Trays--For Fouling Conditions

Dual flow trays are sieve trays without downcomer, they are mainly applied when fouling or polymeriztion has to be expected.

Baffle, Shower Deck, Disc & Donut Trays--For Severe Fouling Conditions
These trays are typically applied in severely fouling services. They are configured so that the liquid flows downward through the column, splashing from one baffle to the next lower one.
Ascending vapor contacts the liquid by passing through the liquid curtains. These trays are used in washing sections where fouling resistance has priority over high efficiency.

Cartridge Trays--For Small Columns

Cartridge trays are typically used for small flanged columns where physically installing the trays inside the column is not feasible. Column diameters range between 300 to 800 mm
Cartridge trays are assembled in bundles for easy and fast installation. They can be equipped with all types of tray decks and downcomers.

Valve Trays--For Broad Operation Flexibility
Like sieve trays, valve trays have been in use as far back as the 1950's but nowadays have become the more popular choice because of their greater operating range properties. Valve trays are essentially flat perforated trays with moveable or fixed valve units with or without a cage structure covering the holes. Moveable valves are disk-shaped type devices which are enclosed within a cage structure or contain legs formed out of the valve disk. Fixed valves are units with integral legs formed out of the tray deck.
Saiptech offers conventional round valve trays, rectangular valve trays, caged valve trays, fixed valve trasy.
