3.3 Cooling Requirements

Parameter
Cooling Capability
Minimum Flow
Maximum Pressure
Pipe Outside Diameter
There are additional cooling requirements for the QBH head. The head should be cooled with an
independent water circuit. A chiller with double temperature outputs is a good option, and an
individual chiller is also a proper choice. The cooling capability should be higher than 600W,
minimum flow should be 2L/min, outside diameter of the pipe should be 6mm, and the most
important, the maximum pressure is 2bar, and de- ionized water must be used.
Wate r temperature setting:
Summer (ambient temperature higher than 30℃)
Winter (ambient temperature lower than 30℃)
Requirements on Cooling Water:
Purified water should be used. In order to prevent mould growing that may lead to pipe blockage,
we recommend to add alcohol about 10% of total volume. The cooling system should equip with
filter. Check and clean the filter every six months.
If the product is used in an environment that ambient temperature is between -10℃ and 0℃, we
recommend to use 30% alcohol, and replace it every 2 months.
If the product is used in an environment that ambient temperature is below -10℃, you must use
chiller with both heating and cooling functions, and keep it in full-time operation.

CAUTION:
The water pressure to the QBH output head must be less than 2bar, or the
head will be damaged. Such damage is not covered by guarantee.
