Dessicant wheel is heart of midsized ventilation system

LDN September Product SemcoThe SEMCO VS Series is a mid-sized ventilation system available in four cabinet sizes ranging in airflow capacity from 2,500 scfm to 15,000 scfm. It can be used to precondition outdoor air going to other conventional air handling systems, or as an integrated system that provides total space conditioning with the additional heating and cooling options available.

The heart of the system is a technologically advanced EXCLU-SIEVE desiccant wheel, whose 3Å molecular sieve-desiccant coating is selective in what it adsorbs from an exhaust air stream. The desiccant rejects airborne contaminants while it transfers water vapor, providing total energy transfer from the exhaust to the supply air stream. Selectivity allows EXCLU-SIEVE to be used in critical applications, including recovery from contaminated air streams. In the past, energy recovery was avoided or limited to sensible-only energy exchange in applications like these. By using the desiccant coating, EXCLU-SIEVE recovers the moisture from the exhaust air stream to the supply air stream without the airborne pollutants exchanging. This very important and unique feature has been well documented through independent laboratory and field-testing.
