Product Deep Dive

Precise temperature sensing, capable of adapting to various fire-risk environments
- 57°C / 68°C: Suitable for common environments such as offices, hotel rooms, school classrooms, etc.
- 79°C / 93°C: Suitable for environments with high temperatures such as kitchens, boiler rooms, and high-temperature workshops.
- 141°C: Suitable for high-temperature drying chambers, asphalt equipment and other special high-temperature industrial environments.
Purchase suggestion: Please select the appropriate temperature sensing level based on the environmental temperature of the installation area. Generally, choose the model that is 30°C higher than the highest ambient temperature.
Two response mechanisms, matching different security requirements
- Standard Response (5mm): The response time is slightly longer and the heat capacity is greater. It is suitable for places where the fire spreads relatively slowly, such as warehouses and garages, and can effectively prevent accidental spraying.
- Quick Response (3mm): Extremely sensitive, it can detect fires earlier and activate the water spray, significantly enhancing the safety protection rate for lives in densely populated areas such as hotels, hospitals, and shopping malls.
Procurement suggestion: For civilian buildings, the rapid response type is highly recommended to ensure the maximum safety of people.
Various appearance options, perfectly blending with the decoration style
- Chrome plating: Modern and fashionable, with a bright and lustrous appearance. It is often used in modern minimalist commercial spaces.
- White paint: Classic and versatile, it can seamlessly blend with the color of the ceiling, being both aesthetically pleasing and discreet. It is the top choice for hotels and residences.
- Bronze base color: Retro industrial style, with a rich texture, often used in distinctive spaces such as cafes, restaurants, and creative districts.

FAQ
Q: How should DN15 and DN20 be chosen?
A: This depends on the design of your fire protection piping system. DN15 (1/2 inch) is the most common type and is suitable for most branch pipe ends. DN20 (3/4 inch) is usually used in situations where a slightly higher flow rate is required. Please make the choice based on the design drawings or consult your engineer.
Q: How can we distinguish temperatures based on colors?
A: The international standard is as follows: orange (57°C), red (68°C), yellow (79°C), green (93°C), and blue (141°C). The color of the liquid inside the glass ball corresponds to these temperatures.
Q: Is multi-batch purchasing supported?
A: Yes, it is supported! We can offer a variety of products with different specifications, temperatures and colors based on your project requirements, providing a one-stop solution to meet all your needs.
