Function ▲
The supply airflow (radial jet) of Halton ULC is directed as required by angling the front plate. The throw length and pressur drop are adjusted by turning the front plate open or closed.
Installation ▲
Halton ULC is installed into the duct with finger screws from inside the valve. The front plate is mounted and the correct adjustment position selected. When the adjustment has been made, lock the front plate.
Adjustment ▲
Adjustment position (A) is determined by angling the fronty plate. The volume frlow rate is determined by setting a probe inside the devicev and reading the pressure difference between the probe and room.
The airflow rate for Halton ULC is calculated with the formula:
ULC-100 | ULC-125 | ||
A | k | A | k |
3 | 0.75 | 4 | 1,34 |
4 | 1,11 | 6 | 1,98 |
5 | 1,56 | 8 | 2,71 |
6 | 1,90 | 10 | 3,40 |
8 | 2,32 | 12 | 4,01 |
10 | 2,77 | 14 | 4,43 |
11 | 3,16 | 16 | 4,69 |
12 | 3,53 | 18 | 5,01 |
13 | 3,88 | 20 | 5,49 |
When the adjustment has been made, lock the front panel. Finally direct the suitable flow pattern.
