Variable Air Volume

VIC has specialized in the designing, developing and realizing the perfect indoor thermal climate with commercial air-conditioning systems. Working closely with clients, consultants, architects and research organizations, VIC seeks to create an indoor climate which offers an optimum in terms of comfort and energy efficiency.

Rectangular NK and NL types are pressure-independent VAV and CAV air volume control terminals. The terminals are designed particularly for systems with large air volumes and duct sizes and for the accurate measurement and control of air volumes using the patented airflow sensor type Flo-Cross airflow sensor. In CAV application, the terminals maintain the required constant airflow independent of the inlet static pressure. In VAV application, the terminals control the air volume to the room, to match the cooling load required thus saving energy consumption in both cooling and heating applications. The VAV or CAV terminals can be used either for supply or return air applications in new or refurbishment projects. The terminals have single wall (type NK) or double wall (type NL) construction and can be optionally supplied with an additional sound attenuator or a hot water or electric reheater.

Features:

  • Pressure independent control functions.
  • Compact design.
  • Volume control range 100% to 10%
  • Low pressure loss over the terminal
  • Single or double wall construction. Multi-leaf damper blade with full
  • Shut-off option & Low noise production.
  • Suitable for large air volumes.
  • Suitable for all control functions VAV, CAV, shut-off to maximise system energy savings.
  • Flo-Cross, 2 x 12 points averaging and signal amplifying airflow sensor, better than 2.5o/o accuracy evenwith irregular duct approach.
  • Maintenance free.
