3.2 Water Requirements
The Hotspot IR Ex mounting plate has internal water channels with inflow and
outflow connections (G1/8 tappings) in the plate edge.
There is no preferred flow orientation. However, if the scanner is mounted in a
position where one of the water connectors is higher than the other, then the
lower connector must be used for the mains water in-flow.
The Hotspot IR Ex mounting plate is supplied fitted with hose connectors suitable
for 9.5mm / 3/8in bore water hose. The water flow rate required will depend
upon each individual application, but 1 litre per minute / 0.26 US gallons per
minute is an absolute minimum, with a maximum water temperature of 30°C /
86°F.
The maximum water pressure is 6kg/cm
2
/ 85psi.
Caution
If the scanner is overcooled to below the local dewpoint, condensation will
form on the unit. This situation must always be avoided.
The temperature of the cooling water must be in the range of 15 to 30°C /
59 to 86°F.
A constant supply of clean water is recommended, as this reduces the
likelihood of blockages within the mounting plate.
Note
The Hotspot IR Ex has been certified for safe use in an ambient temperature
range of -20 to +60°C. However, the scanner will only perform correctly
if the head temperature is in the range +5 to +60°C. Due to internal
temperature rise, water cooling will be needed above an ambient
temperature of approximately 50°C in order to keep the head temperature
below 60°C.
