Notes:
¹     Cooling capacity ratings are with process coolant @ 20°C / 68°F.
²     Temperature stability performance requires a stable heat load input.
*     Data shown is with 30°C / 86°F (unrestricted) ambient air.
*     See Thermal Performance chart for cooling capacities @ other process temperatures.
*     Specifications are subject to change without notice.
