Anti-Sweat Heaters in Refrigerated Display Cases PDF

Anti-sweat heaters (ASH) are typically applied to low-temperature refrigerated display cases to prevent glass doors from fogging and cold surfaces from forming condensation. Commonly, ASH stay on at full load around the clock. Their contribution to the cooling load and electric power consumption of the refrigeration system can be significant. Using energy-efficient technologies can reduce the power consumption of ASH and the refrigeration system.
