Speed check
Speed Check is a term used to describe how fast a unit can
cool across 20°C when it is running at maximum capacity. The
unit of measure is “degrees per minute”. This will provide a
number that is easy to obtain and compare.
1. Find the DROP figure from the table. (For example, the
HX100 with a PD-1 pump has a drop of 1.4°C.)
2. Divide the drop in half. (Example: 0.7°C)
3. Add this half to 20°C to find the START point. (Example:
20.7°C)
4. Subtract this half from 20°C to find the STOP point. (Ex-
ample: 19.3°C). Now the entire drop is centered about 20°C.
5. Connect the unit’s inlet and outlet with as short a loop of hose
as practical. Insert a thermometer with 0.1°C resolution in the
loop.
