QCID System

System Overview

The QCID system provides both ventilation and odor control for point source areas. QCID, which stands for "Quick-Contact-In-Duct" features a contact time of 0.3 seconds. The system has the smallest footprint of any comparably sized odor control system and is an excellent choice when space is limited. This system is designed to use NuTech's Chi-X or DeAmine Odor Eliminators. The targeted odors are oxidized organic odors for applications with fairly consistent odor loading.

Seasonal variation in ventilation requirements is accommodated by the use of a two-speed or variable speed fan motor. Fabricated from stainless steel, the QCID system can be supplied in sizes from 1,000 to 8,000 cfm for situations where the total static pressure requirement is 3.5" or less. Custom designed, the QCID is built to handle any needed air inlet and outlet configuration. Systems are typically floor mounted, however; mounting options are available to fit the site. Installation costs average 10 to 20% of the capital costs.

With a QCID, NuTech guarantees odor reduction at the discharge stack to 200 odor units or less (D/T), with Butanol intensity of 3 or less. Butanol intensities as low as 1 are possible. Effectiveness on hydrogen sulfide is limited to 1 ppm. If H2S levels exceed one ppm, companion treatment for H2S should be considered.
