NOTE: For Design I chillers, the 150 psig (1034 kPa) standard waterbox cover weights (NIH, 2-pass

cover) have been included in the heat exchanger weights shown in Table12. Design II chillers are

equippedwith a linear ﬂoat, and chiller weight is based on a 300 psig (2066 kPa) waterbox with 1-pass

arrangement.
