Glycol Heat Tracing Keeping the right temperature

Glycol heat tra­cing is of­ten used in in­dustry to pro­tect pipes, boil­ers, pumps, and other equip­ment from frost in winter, or to keep warm wa­ter at re­quired tem­per­at­ure.  It in­volves heat­ing the in­stall­a­tions by means of 1/2″ SS tubing con­tain­ing heated glycol that is strapped…

Using Glycol In Closed Loops

  How does the glycol protect the loop from freezing?Pure water freezes at 32° F, but a 60% solution of ethylene glycol pushes the freezing point down to -60° F. While the freezing point of pure glycol is only -39° F, the synergy between glycol…

Introduction to heat trace

Heat tracing is the generic term which refers to the applica­tion of heat to a pipeline or vessel to prevent freezing, to thaw frozen fluid, to maintain viscosity or temperature of a fluid, or for other reasons such as to keep components from sepa­rating or…
