Heatecx Limited
The intelligent explosion-proof temperature controller developed by our company is a new generation product specifically designed for terminal temperature control in electric heat tracing systems. It is comprehensively optimized on the basis of mechanical thermostats, integrating power control, current protection, fault alarm, and monitoring communication into one unit. It offers superior performance, higher precision, and is suitable for various hazardous environments.
This product is a core control device for electric heating/heat tracing systems in industrial fields such as petroleum, chemical, natural gas, and power generation. It employs an intelligent digital display thermostat, featuring telemetry functions like 4-20mA remote transmission and RS485 communication, enabling precise temperature management and remote monitoring. The controller adopts a fully flameproof enclosure design, with comprehensive explosion-proof markings (Exd IIB/C T6 Gb, Ex tD A20 IP65 T80℃), making it suitable for explosive gas atmosphere Zone 1, Zone 2, and combustible dust atmosphere Zone 21, Zone 22. The enclosure can be made of aluminum alloy, stainless steel, or engineering plastic. It has a robust structure with a protection rating of IP65, meeting the usage requirements for outdoor and harsh industrial environments.

Standard Optional Configurations:
Current Rating: Models with different rated currents such as 20A, 25A, 40A, 60A, 100A can be selected based on load requirements.
Enclosure Material and Dimensions: Choose enclosure material from aluminum alloy, stainless steel, or engineering plastic based on the application environment (corrosiveness, strength requirements). Different current ratings correspond to different external dimensions.
Installation Method: Choose wall-mounted, pipe-mounted, or floor-standing installation based on site conditions.
Cable Entry Specification: Match cable entries from G1/2" to G2" according to cable specifications.
Customization Services:
Special Electrical Parameters: Non-standard current values between 10A and 100A, or other non-standard voltages, can be custom-made.
Special Functions: The functions of the intelligent thermostat can be freely selected or specially made according to user requirements.
Special Interface and Dimensions: Special requirements for cable inlet/outlet threads, sensor interface, and external dimensions can be noted for customization.
Specific Certifications: The product already complies with multiple international and domestic standards. Other specific certifications can be negotiated based on project needs.
The core difference lies in the degree of integration, functionality, and level of intelligence. The intelligent product, on the basis of the mechanical type's simple power control, highly integrates electrical safety functions such as earth leakage protection, overcurrent protection, phase loss detection, and fault alarm. It also incorporates a communicable digital intelligent thermostat that supports remote monitoring (4-20mA/RS485). In contrast, the mechanical type typically has only the basic on/off temperature control function, lacking intelligent diagnostics and remote interfaces. The intelligent type holds significant advantages in safety, management convenience, and system integration.
