HLTSTAT20C

The nVent HLTSTAT20C Hazardous Location Heater Thermostat is a robust, precision-engineered thermal management solution designed to protect critical electronic components in extreme and hazardous environments. Engineered by nVent, a global leader in thermal management and electrical enclosures, this thermostat ensures reliable operation where freezing temperatures, condensation, and corrosion pose significant risks to system integrity. The HLTSTAT20C is specifically engineered for hazardous locations, providing automatic temperature control to prevent damage from cold-induced failures, moisture accumulation, and material degradation. At the core of the HLTSTAT20C is a highly responsive bimetallic sensor element that activates the heating circuit when ambient temperatures fall below the 20°C set point, and deactivates it once the temperature rises above 28°C. This narrow hysteresis ensures minimal temperature fluctuation, maintaining optimal operating conditions for sensitive electronics. The thermostat is housed in a durable, black anodized aluminum enclosure, offering superior corrosion resistance and mechanical strength—ideal for marine, offshore, and industrial environments where exposure to seawater, chemicals, and abrasive conditions is common. Certified for global hazardous location compliance, the HLTSTAT20C meets stringent ATEX, IECEx, CE, and cCSAus standards, including II 2 G Ex db IIC T6 and II 2 D Ex tb IIIC T80°C classifications. This makes it suitable for use in Zone 1, Zone 2, Zone 21, and Zone 22 hazardous areas as defined by international safety regulations. The unit is also certified under NEC and CSA for North American installations, ensuring seamless integration into both international and domestic projects. With a compact footprint measuring 3.5 inches (90 mm) in height, 1.6 inches (40 mm) in width, and 1.2 inches (30 mm) in depth, the HLTSTAT20C is designed for space-constrained enclosures and control panels. It weighs just 1.1 lbs (0.50 kg), simplifying installation without compromising durability. The thermostat features a 1-meter-long silicone cable with oil and notch resistance, rated at 3x AWG16 and 9.4 mm diameter, ensuring reliable connectivity even in high-vibration or high-temperature environments. With an IP66/IP68 rating (1 bar/30 min), it withstands dust ingress, high-pressure water jets, and temporary immersion—critical for outdoor and industrial applications. Professionals across industries such as oil and gas, chemical processing, water treatment, and food and beverage rely on nVent’s thermal management solutions for uncompromising performance and safety. The HLTSTAT20C is ideal for protecting control panels, junction boxes, sensors, and communication equipment in refrigerated storage, outdoor cabinets, and harsh process environments. When paired with nVent’s line of hazardous location heaters (such as the DAHHL series), it forms a complete thermal management system that prevents condensation, maintains temperature stability, and extends equipment lifespan. nVent’s reputation for innovation and reliability is built on decades of expertise in thermal protection and hazardous area solutions. With global certifications, a commitment to quality, and a focus on engineering solutions that meet real-world challenges, the HLTSTAT20C represents the gold standard in hazardous location thermostats. Whether you're designing a new installation or upgrading existing infrastructure, the HLTSTAT20C delivers the precision, durability, and compliance required to safeguard your most critical assets.
