HQ Variable Air Volume
Model HQ terminals unit are available in 7 different sizes covering the volume range from 0.024 mJ/s to 1.885mJ/s, suitable for supply or extract applications and inlet static pressures up to 1500 pascals. Colman's model HQ terminal units provide air volume control whilst meetings today's acoustic requirements without the need for additional attenuator sections.
The terminal units consist of a low noise, removable, blind type damper, multipoint flow sensor and integral attenuator fitted within a sheet metal housing.
The built-in attenuator section is manufactured from non fibrous acoustic material to eliminate the danger of fibre migration.
Control components are fitted to an external heavy duty mounting plate and are supplied calibrated and wired prior to shipment. A control panel enclosure is fitted as standard. Colman's unique multipoint flow sensor allows accurate control of the terminal unit air volume in conjunction with either electronic or pneumatic control systems, and easy on site commissioning without loss of control, due to the incorporation of additional flow measurement tappings.
