Heat Trace / Freeze Protection Thermostats - THL

THL: NEMA 4X Ambient Air Sensing Maintaining proper viscosity and flow is critical in heat trace or freeze protection applications. The THR remote mount thermostats utilize a stainless steel bulb and capillary design to accurately sense temperature at key points along a pipe. The THL direct mount thermostats feature liquid-filled thermal assemblies and sense air temperatures from 15 to 140?F. Both models are epoxy coated to seal from moisture and contaminants in compliance with NEMA 4X requirements.
