Hot Water Tracing System

From Therm-Omega-Tech, Inc.
 

 
The THERM-OMEGA-TECH HAT valves provide substantial savings when compared to the cost of operating conventional steam traps. The HAT valves sense condensate temperature and open to allow flow only when the condensate temperature is below the setpoint, well below saturated steam temperature. The condensate forms a liquid seal ahead of each valve preventing live steam losses. Also, the sensible heat in the condensate between steam temperature and the HAT discharge temperature is used for heating. Most properly functioning conventional steam traps have inherent live steam loses: at least 2 lbs/hr. for inverted bucket traps, and over 5 lbs/hr for disc traps. Actual field studies have shown that live steam losses of disc traps increase considerably with time in service, with losses of 20 lb/hr after less than one year of service being not unusual. Losses from other types of conventional traps also increase with time, but usually less than losses from disc traps. For this example, we will use 2 lb/hr of live steam loss for conventional traps in good condition and compare this to HAT valves which have zero live steam loss. Further, HAT valves achieve additional savings by discharging condensate at reduced temperature. These additional savings can be calculated based on the value of the heat content at varying discharge temperatures.
