Transcript of Linear Low-Induction Diffuser

If temperatures at workers' chest level (~ 1.2 meters/4 ft) could be kept at 28C (82F) or lower,
Using perforations to
To a microperforated
half-round diffuser
Ambient temperatures of 35C (95F) around one process dictated frequent worker breaks to avoid overheating
Linear Low-Induction Diffuser
An innovative solution to a challenging application
workers could more easily prevent overheating and require fewer breaks
Multiple concepts were considered as potential solutions.
create an air curtain to prevent induction
with fabric curtains to direct cool air downward and prevent induction
Extensive CFD modeling and lab testing by Prihoda s.r.o. proved the concept as viable
and a prototype unit was built and installed at Prolam.
Field test results were outstanding!
The customer is very happy and sees strong long-term potential for this solution
Nozzles with special microperfoated cones.......
Cool sunglasses did not yield
measureable improvements...
no matter how much we wish they did.
An extremely high delta between supply and room temperatures resulted in an extremely high induction rate of room air.
Meaning traditional methods of distribution like perforations or nozzles would not adequately cool at the worker level.
Fewer breaks!?!?!?!
What you talkin' 'bout, Willis?
Deflection issues uncovered during prototype field testing were corrected by angular adjustments to Prihoda's patented Directional Microperforation
Prototype Field Smoke Test
Northern Quebec Prihoda rep, Armeco, came to us with a challenging worker safety and productivity application their client, industrial contractor Cytech-Corbin had encountered with laminated floor manufacutrer Prolam
