Engineered Simplicity
Metal Sieve Trays deliver reliable vapor-liquid contact through precision-perforated plates requiring zero moving parts. Designed for fouling/corrosive services, they offer 30-50% cost savings over valve trays while enabling extended liquid residence times (>60s) – ideal for refinery scrubbers, chemical reactors, and processes where phase contact duration outweighs turndown flexibility needs.
