Product Technology
Inside Soltree Technology
Engineered for reliability. See what makes the industry standard for miniature fire suppression.
Aerosol Generator Compound (Solid State)
A stable solid mixture of oxidizer and reducing agent. Converts to fire-suppressing gas only upon activation. Non-pressurized.
Advanced Cooling Vents
Housing design directs heat away to ensure casing temperature remains safe (<75°C).
Discharge Outlet
Precision nozzle enables rapid flooding of the cabinet in ≤ 6 seconds.
DIN Rail Mounting Clip
Standard 35mm DIN rail integration allows it to sit perfectly alongside MCBs and terminal blocks.
Thermal Activation Cord
(Blue line) Heat-sensitive cord activates mechanically at 170°C, ensuring operation even during total power failure.

FAQ
Knowledge About DIN Rail Aerosol Fire Extinguishers
A DIN Rail Aerosol Fire Extinguisher is a compact fire suppression device designed specifically to snap onto standard 35mm DIN rails found in electrical cabinets. It is used to protect enclosed spaces like meter boxes, server racks, and low-voltage switchgear by extinguishing fires at the source before they spread.
No. Soltree aerosol produces a micron-sized particulate that is non-corrosive and non-conductive. After a discharge, the fine dust can be blown out or wiped away. It does not damage circuit boards like water or foam would.
Installation is "plug-and-play." The QRR series features a specialized mounting clip that attaches directly to the 35mm guide rail. For cabinets without rails, the device also supports magnetic suction or screw fixation, allowing flexible placement near potential fire sources.
No, it can operate passively. The primary activation method is a Thermal Sensing Cord that snakes through the cabinet. If the temperature hits 170°C, it triggers mechanically. However, for Smart models, electrical activation via smoke sensors or remote control is also supported.
No. Unlike traditional gas cylinders, Soltree aerosol extinguishers are non-pressurized solid-state devices. They are maintenance-free for their entire 10-year service life. You do not need to perform annual weighing or pressure checks.
Keep the nozzle at least 0.3m away from the protected object (like wires or breakers) and 1.5m away from personnel. Ensure there are no obstacles within 500mm directly in front of the nozzle.
Yes. The device includes "Fire Feedback" and "Switch Output" terminals. When activated, it sends a passive contact signal to your main fire alarm system or BMS to indicate a discharge event.
The Heat Aerosol Fire Extinguishing Device uses a new-generation formula that is non-corrosive and safe for electronics. While a fine particulate settles after discharge, it is non-conductive and can be cleaned. It is designed specifically for electrical environments.
For the Smart Series (connected to AC220V), the device has a built-in Power-off Continuous Work feature. It can continue to detect and operate for at least 10 seconds after a total power loss, ensuring protection during electrical faults.
Yes. We offer specific models (RS485 Type and 4G Type) that integrate Modbus protocol. This allows real-time monitoring of temperature, smoke density, and device status via a PC or Mobile App.
Yes. The device is built for harsh environments. The integrated type works from -40°C to +70°C, and the standard type operates from -50°C to +90°C, making it ideal for outdoor PV inverters and battery storage systems.
