Swirl diffusers are designed for airconditioning of room with floor to ceiling heights from 2,6 to 4m and temperature difference between supply and room air of +10K to 10K. Due to the rotary swirling motion of the air discharge, induction of room air occurs very quickly. Variable diffusers are designed for rooms with changing thermal loads which require different conditioning (heating, cooling). They are suitable for rooms with floor to ceiling height of up to 10 m and recommended temperature difference between supply and room air +10K and 10K. Required conditioningis achieved by the means of manual or power driven blades adjusting.

Due to the rotary swirling motion of the air discharge, induction of room air occurs very quickly. Swirl diffusers are sui- table both for comfort as well as industrial air- conditioning. Description Swirl diffusers consist of plenum box made of galvanised sheet steel and diffu- ser face. Diffuser face is made of sheet steel powder painted in RAL 9010 or any RAL colour upon customer’s request. OD-8/TR OD-8/TR automatically adjusts the inlet in effect during heating. During transition periods, the diffuser automatically adjusts the optimum discharge angle which contributes to increased comfort level in the room. ■ Variable swirl diffusers Application Variable diffusers are designed for rooms with changing thermal loads which require different conditioning (heating, cooling). They are suitable for rooms with recommended temperature difference between supply and room air +10K and -10K. Required conditioning is achieved by the means of manual or power driven blades adjusting. Variable diffusers are suitable for both comfort and industrial conditioning. Description Variable diffusers consist of plenum box made of galvanised sheet steel and diffuser. Diffusers are made of sheet steel or sheet aluminium (OD-11) and powder painted in RAL 9010 or any RAL colour upon customer’s request. OD-11V/TR At OD-11V/TR diffuser, centrally adjusta- ble blades can be adjusted automatically with the thermostat regulation. Thermo- stat perceives temperature of the supply air and automatically adjusts the blades angle.
