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. NEMA 7
stats TXR and TXL are designed for Class I,
Division I and 2, Groups B, C, D, and Class 2,
Division I and 2, Group E, F, G.
WARNING: Hazard of Fire. These devices function as temperature controls only. Because they do not fail-safe, an approved temperature and/or pressure safety control must be used for safe operation.
