condensation up to a dew point rating of 74°F (23.3°C),
K = 0.25. Chillers in high humidity areas or ice storage,
low leaving water temperature (less than 36°F [2.2°C]
chilled water temperature/glycol) units, may require
double thickness to prevent formation of condensation.

NNootteess::
• Bulbwells, drain, and vent connections must be accessible after insulating.
• All units with evaporator marine waterboxes: wrap waterbox shell insulation with strapping and secure
strapping with seal.
• Evaporators with ASME nameplates must have insulation cut out around the nameplate. Do NOT glue
insulation to the nameplate.
• Apply 2-in. (50.8-mm) wide black tape on overlap joints. Where possible, apply 3-in. (76.2-mm) wide strip of
0.38-in. (9.7-mm) thick insulation over butt joint seams.
• Insulate all economizer supports.
