Reliable and Advanced Heat Detection Solutions for Hazardous Environments

The HTD-8800-FLP, HTD-8811-FLP, and HTD-8822-FLP are robust and reliable heat detectors designed to safeguard industrial environments, especially in hazardous areas. These devices are engineered with advanced fameproof enclosures, making them suitable for industries such as oil & gas, chemical plants, heat treatment plants, automotive sectors, and more.

The HTD-8800-FLP model provides fast and accurate detection of heat buildup in ambient temperatures, with factory preset temperature set points (50°C, 60°C, 70°C, 80°C, 90°C, and 110°C). It features auto-reset operation, returning to a normal state after the temperature cools down. The device comes with IP66-rated protection, ensuring high resistance against dust and water ingress. Its cast aluminium alloy housing is durable, while the double compression cable glands and EX-proof cable entry ensure safe installation in explosive environments.

The HTD-8811-FLP is an enhanced version, equipped with two SPDT relay contacts for alarm output, as well as a hooter cum flasher for immediate alerts. This model is ideal for applications requiring immediate attention in case of overheating. It also supports a 4-20mA output, enabling seamless integration into control systems. With a response time of less than 60 seconds, it ensures timely action in

critical situations.

For advanced communication capabilities, the HTD-8822-FLP integrates RS-485 communication with the MODBUS RTU protocol,

offering remote monitoring and control. It also includes a 4-digit seven-segment LED display, providing clear visibility of the current status. This model is especially beneficial for real-time monitoring in automated environments. Certified by CIMFR for IIA, IIB, and IIC group approvals, these heat detectors meet stringent international safety standards, including IS/IEC 60079 and IS/IEC 60529, ensuring

their reliability and safety in industrial settings.
