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.
