ExS6011-T Series Explosion-Proof Dual Temperature Switch Advances Industrial Temperature Control
Beijing China-September 22, 2026
I. Product Positioning
The ExS6011-T series explosion-proof dual temperature switch is specifically designed for workplaces with explosive hazardous gases, vapors, or combustible dust, such as oil and petrochemical facilities. Used in conjunction with explosion-proof damper actuators, it provides overtemperature safety protection for damper systems.
The product holds three major certifications: China Explosion-Proof Certification, EU ATEX Certification, and International IECEx Certification, allowing installation in major hazardous areas worldwide.
II. Key Features Two optional actuation temperatures: 72℃ or 150℃, adapting to different process scenarios
Universal power supply: supports AC/DC 24V and AC 110–240V
High protection rating IP66: dust-tight and protected against powerful water jets, suitable for outdoor and harsh conditions
Explosion-proof marking: Ex db ⅡC T6 Gb / Ex tb ⅢC T85℃ Db — covers Zone 1/Zone 2 gas hazardous areas and Zone 21/Zone 22 dust hazardous areas, meeting the highest safety grades
III. Operating PrincipleUnder normal conditions, both TS1 and TS2 remain closed, and the actuator operates normally with power supplied.When the ambient or duct temperature exceeds the set point → TS1 or TS2 opens → actuator loses power → damper returns to the safe positionIV. Certifications & Standards
The product complies with the following major standards, with a complete certification chain:
Gas environments:
- IEC 60079-0:2017 / EN 60079-0:2018 — General requirements
- IEC 60079-1:2014-08 / EN 60079-1:2014 — Flameproof enclosure “d”
Dust environments:
- IEC 60079-31:2022 / EN 60079-31:2014 — Enclosure “t” dust ignition protection
Certificates held: China Explosion-Proof Certification + ATEX + IECEx
V. Typical Applications
| Industry | Applications |
|---|---|
| Oil & Gas | Refinery heater dampers, tank ventilation, oil/gas recovery systems |
| Petrochemical | Drying equipment, VOCs treatment system dampers |
| Dust-prone industries | Grain/feed processing, pharmaceuticals, paint shops, metal powder handling |
| New energy | Lithium battery plants, hydrogen facility ventilation |
| Environmental engineering | RTO/RCO waste gas treatment, waste incineration ventilation |
| Marine & offshore | Hazardous-area ventilation on tankers/drilling platforms |
In a nutshell: Wherever there are explosion-proof dampers, an explosion-proof temperature switch is needed for overtemperature protection.
VI. Selection Guide
| Operating Condition | Recommended Model |
|---|---|
| Low normal duct temperature, early warning required | 72℃ |
| High-temperature processes, hot-air recirculation, drying/curing equipment | 150℃ |
Selection principle: The actuation temperature should be higher than the normal operating temperature but lower than the maximum temperature the equipment can withstand.
VII. Installation & Safety Instructions
Installation requirements:
- Must be installed by trained or experienced personnel
- Never perform work with power on; strictly follow installation procedures
- Cable glands must bear the corresponding explosion-proof certification
- Tightening torque for flameproof joints: 5.5 Nm
Safety warnings:
- Never open the cover while energized; do not disassemble or modify without authorization
- Wait 25 minutes after power-off before opening the cover; wipe with a wet cloth (anti-static) when opening
- Flameproof mating surfaces must not be repaired or modified by the user
- Contains electrical/electronic components — dispose of as e-waste per local regulations; do not discard as ordinary waste
- Not applicable in areas affected by charge generation, mechanical friction, separation processes, electron emission, or pneumatic dust conveying
VIII. Why Choose the ExS6011-T Series?
| Advantage | Value |
|---|---|
| Triple international certifications | One product, global use — simplified procurement |
| Two temperature options | Adapts to low- or high-temperature processes |
| IP66 protection | Suited for outdoor, dusty, humid, and harsh conditions |
| Universal power supply | Compatible with various supply voltages worldwide |
| Long-life design | Manual operation ≥ 1,000 cycles — reduced maintenance |
Wherever there are explosion-proof dampers, the ExS6011-T explosion-proof temperature switch has its place.
