Air terminal devices for panel diffusers

 

Description

Air terminal units of UDP series are constituted by a helical diffuser on square panel complete of plenum fully equipped

UDP units are applicable on ceiling for supply or extract air.

High induction diffusers are available and compatible with different architectural solutions. The plenum or calm box, allows to eliminate or reduce the no-uniformity of the velocity profile of the air coming from the supply duct. In this way, the throw characteristics of the diffuser will comply with those laid without asymmetry or directionality caused by unwanted velocity gradients.

Cestaro Bernardo Srl is able to offer in a short time both standard and special constructions of dimensional and construction specifications required by the customer.
