Sieve Tray

A sieve tray is a low-cost type of tray by which a bubble cap tray is replaced. It has been used as separation equipment for a long time since it was developed in the early 1950’s. If it is properly designed, it gets abreast of any other tray in efficiency and capacity. In addition, the structure is simple, so it can also be used for fouling service.

Perforations are 1/2 inch diameter, but we can provide designs with various hole sizes ranging from 1/8 inch to 1 inch. The smaller the hole size, the better the efficiency. If the hole size is big, it has better anti-fouling characteristics.

Sieve trays cost relatively low, and they make maintenance easy. Meanwhile, their drawback is that the turndown ratio is lower than that of valve trays and bubble cap trays, so they are not suitable to operate at variable loads. For these reasons, they are the most economical tray option when low turndown is required.
