Chemelex Launches Raychem Elexant 3500i Thermostat: Revolutionizing Industrial Heat Tracing with Speed, Reliability, and Connectivity
Chemelex, a global leader in advanced heat tracing technologies, has unveiled its latest innovation: the Raychem Elexant 3500i family of electronic thermostats. Designed on a highly configurable hardware platform, the Elexant 3500i series empowers end users to precisely tailor heat tracing control solutions to meet their unique operational demands. This new family of thermostats marks a significant expansion of Chemelex’s already comprehensive portfolio of heat tracing control and monitoring products, delivering enhanced performance, ease of use, and connectivity.
Reliable Heat Tracing Control for Industrial Applications
Amy Escobio, Vice President of Product at Chemelex, expressed enthusiasm about the launch: “We are thrilled to introduce the Raychem Elexant 3500i. With unmatched versatility, efficiency, and connectivity, the Elexant 3500i redefines heat tracing control, enabling cost savings and helping prevent costly downtime for our customers.”
Industrial heat tracing systems are vital for maintaining temperature-critical processes, preventing freezing in pipes, ensuring process stability, and protecting sensitive equipment. Reliability in these systems is paramount because failures can lead to significant operational disruptions and financial losses. The Raychem Elexant 3500i family addresses these needs through a range of advanced features that not only ensure reliable control but also provide comprehensive monitoring and diagnostics.
Among the key features of the Elexant 3500i are advanced alarming functions that alert operators to system faults, current sensing for precise load monitoring, ground fault detection to enhance safety, and automated 24-hour heat trace system health checks that enable proactive maintenance. These features are critical in identifying potential issues before they escalate into failures, thereby enhancing system uptime and reducing operational risk.
Designed for Fast Installation and Future-Proof Upgrades
One of the standout advantages of the Raychem Elexant 3500i is its design focus on ease of installation and serviceability. The thermostats are offered in either wall-mounted or pipe-mounted enclosures, each engineered to act not only as a thermostat but also as a power connection kit. This dual-function design simplifies the installation process, reduces the number of components needed, and minimizes the total installed cost for industrial users.
Installation efficiency is further improved by quick connect terminals that reduce wiring complexity and installation time. The product includes an internal hub grounding plate that eliminates the need for additional grounding components, streamlining the setup process and reducing the potential for installation errors.
Moreover, the Elexant 3500i is built with interchangeable electronic modules. This modular approach means that upgrades, repairs, or configuration changes can be performed with minimal downtime and without the need for complete replacement of the thermostat hardware. This feature future-proofs the investment for customers, allowing them to adapt and expand their systems as operational needs evolve.
To ensure performance in even the most demanding environments, the Elexant 3500i family has earned industry approvals for hazardous areas, making it suitable for use in extreme and potentially explosive industrial settings. This certification guarantees that the thermostats meet rigorous safety and reliability standards required in oil and gas, chemical processing, and other high-risk sectors.
Empowering Users with Full Connectivity and Control
In today’s digital industrial landscape, connectivity is not just a convenience but a necessity. The Raychem Elexant 3500i thermostat family places connectivity at the core of its design philosophy. Configuration and monitoring of the thermostats can be performed wirelessly via a secure Bluetooth connection using the Elexant Connect App, available for smartphones and tablets. This user-friendly app allows technicians and engineers to quickly set parameters, update settings, and review system status without needing physical access to the thermostat unit, which can be located in hard-to-reach or hazardous areas.

Beyond local wireless control, the Elexant 3500i supports integration with distributed control systems (DCS) through Modbus RTU communication protocols. This integration capability enables centralized monitoring and control, allowing plant operators and maintenance teams to access real-time system data remotely, make informed decisions, and respond rapidly to any issues. The ability to integrate into modern control architectures is a key feature that helps facilities achieve smarter, more efficient operations.
A New Benchmark in Heat Tracing Solutions
The launch of the Raychem Elexant 3500i represents a significant step forward in the evolution of heat tracing controls. Its configurable hardware platform offers unmatched flexibility, enabling a wide range of applications from basic freeze protection to complex process temperature maintenance.
By combining reliability, rapid installation, hazardous area approvals, and full connectivity, Chemelex has created a solution that meets the demands of today’s industrial operators who seek cost-effective, safe, and easy-to-manage heat tracing systems.
Amy Escobio added, “Our goal with the Elexant 3500i family is to empower our customers with technology that not only meets their immediate needs but also supports their long-term operational goals. We believe this thermostat series sets a new standard for heat tracing control in the industry.”
