Air diffuser ILQsf

Overview
The ILQsf from LTG is a layer-ventilation diffuser system for energy-efficient, on-demand ventilation of industrial halls. Designed for both heating and cooling operation, it enables draught-free air supply and targeted removal of thermal and material loads.

Key benefits

• Energy-saving by intelligent on-demand ventilation: variable volume flows at low operating pressure for reduced energy consumption and controlled indoor conditions
• Consistently high ventilation efficiency across a wide range of air volume flows and temperatures
• Flexible adjustment: available with automatic mechanical, motorized (electrical) or manual control
• Effective thermal and contaminant removal through layer ventilation principle
• Draught-free supply at workstations: high local thermal comfort even close to the diffuser
• LTG awarded BEST OF 2016
