SKU:DHCX151300T4A
BriskHeat DHCX and DHNX Series Hazardous-Area Rated Silicone Rubber Drum Heaters provide a rugged, high-efficiency heating solution designed to maintain optimal viscosity, deliver reliable freeze protection, and keep critical process materials at elevated temperatures. Engineered with durable, moisture-resistant silicone rubber, these heaters deliver uniform thermal distribution around the body of the drum or pail—preventing material degradation, eliminating waste, and ensuring consistent fluid flow in challenging work environments.
Note: DHCX Series comes with a NEMA 7 temperature controller and high-temperature limit indicator light. DHNX Series requires an external temperature controller (not included).
- Explosion-Proof Hazardous Location Approval: FM Approved for Class I & Class II, Division 2 environments.
- Industrial-Grade Environmental Resistance: Built with an IP54 moisture and chemical resistant silicone rubber outer shell that withstands harsh chemical exposure, washdowns, and demanding industrial conditions.
- Heavy-Duty Power Connectivity: Equipped with factory-installed explosion-proof plugs to ensure fast, compliant hookup in rated environments.

Catalog/Specifications Sheet
Instruction Manuals
Q: What types of container heaters are available?
A: Common container heater types include:
- Full coverage drum heaters
- Full-coverage IBC tote tank heaters
- Pail heaters
- Silicone drum and pail heaters
Q: What are container heaters used for?
A: Container heaters are commonly used to:
- Viscosity control
- Maintain process temperatures
- Protect temperature-sensitive products during storage
Q: How do container heaters improve viscosity control?
A: Heating materials to their recommended temperatures can lower viscosity, making liquids easier to pump, mix, transfer, and dispense while improving process efficiency.
Q: Can container heaters be used for hazardous locations?
A: Our ATEX Drum, Tote, and Gas Cylinder container heaters are designed and certified for hazardous locations. It is always important to verify approvals and certifications before installation in hazardous environments.
Q: Can container heaters prevent materials from freezing?
A: Yes. Container heaters are commonly used to maintain temperatures above freezing, helping protect materials from solidification, crystallization, or freeze damage during storage and use.
Q: How do I properly store my drum & tote heater?
A: We suggest that you lay your drum heater on a flat surface when not in use.
Q: What lengths and widths do tote tank heaters fit?
A: Any footprint between 40” x 40” (1016mm x 1016mm) and 48” x 48” (1219mm x 1219mm).
Q: Are there safety features for tote tank heaters like high-limit thermostats?
A: Yes, the wrap-arounds have built-in 195°F (91°C) manual reset high-limit thermostats and are grounded.
Q: Do cylinder warmers have adjustable built-in controllers?
A: No, the heaters are designed to keep the cylinders warm and temperatures will vary depending on environmental conditions. GCW and HCW heaters are built with self-regulating heat trace meaning they automatically adjust temperature depending on application and ambient conditions.
Q: Are cylinder warmers plug-and-play?
A: The 120V GCW models include a plug, but other models have ferrule-crimped leads.
