3. Turn on the chiller and adjust the coolant temperature setpoint to between 18 °C to 22 °C.
Regulate coolant flow to 3.8 lpm (1.0 GPM) at less than 414 kPa (60 PSI) of pressure.
4. Closely examine all cooling connections and verify that there are no leaks.
Air-cooled connections
Side cooling
Air-cooled v30 (SAG) lasers are shipped without cooling fans so customers must provide some type of
air cooling to prevent overheating. NOVANTA recommends using two cooling fans rated for at least 4.0
m
3
/ min (140 CFM) at a static air pressure of 13.2 mm H
2
O (0.52 in H
2
O). The cooling fans should measure
approximately 120 × 120 mm (4.7" × 4.7") and have at least 57.2 mm (2.25") of unobstructed clearance
between the outside edge of the fan housing and any mounting surface or enclosure.
The OEM v30 does not provide a voltage output sufficient to power cooling fans, so customers must
provide an external power source to drive the selected cooling fans. Because of the heat generated by
internal RF circuitry, establishing significant airflow evenly over the entire surface of the combined
laser/RF chassis is vitally important to the performance and longevity of the laser.
For free-space mounting (no fan shroud), position the fans symmetrically as shown in Figure 1-4 where
they are centered horizontally with the laser chassis and vertically with the heatsink fins. Position both
fans so the inside face is no more than 76 mm (3.0") from the v30’s heatsink fins.
Caution: Possible Equipment Damage
Operating the laser at coolant temperatures above 22 °C (72 °F) may result in decreased
performance and/or premature failure of electronic components.
