Air & Water-Cooled Protective Housing 
Material Option: 201 / 304 / 316 stainless steel are available. Welded base or hoop mount can be selected according to site requirements.
LRFL-I Air-Cooled Protective Housing
The maximum load capacity is ≤20kg, and the self-weight is 3kg. This air-cooled housing achieves cooling performance comparable to conventional water cooling solutions. It is especially applicable for sites with water shortage and areas where water pipes are easy to burst under low temperature in winter.
The applicable ambient temperature ranges from -50℃ to +300℃, and the allowable ambient dust concentration is ≤200mg/m³ (standard based on cement dust). The applicable compressed air temperature is ≤35℃, the working pressure is 0.3‑0.4MPa, and the compressed air flow rate is 0.3‑0.6m³/min.
The housing reaches IP65 ingress protection grade. Standard configuration includes 1 set of air-cooled housing, 1 semi-fixed pan-tilt, 1 stainless steel bracket and 1 metal hose. A vortex cooling tube is optional.
This housing is compatible with various CCD color and black-and-white cameras as well as 3× varifocal lenses (cameras and lenses are optional accessories). It can be installed on a semi-fixed pan-tilt or a 15kg motorized pan-tilt.
LRSL-I Air & Water-Cooled Protective Housing
The maximum load capacity is ≤20kg, and the self-weight is 3.5kg. Featuring excellent comprehensive cooling performance, this model is suitable for high-temperature working conditions and regions with sufficient water resources.
The applicable ambient temperature ranges from -50℃ to +600℃, and the allowable ambient dust concentration is ≤200mg/m³ (standard based on cement dust). The applicable compressed air temperature is ≤35℃, the working pressure is 0.3‑0.4MPa, and the compressed air flow rate is 0.3‑0.6m³/min.
For water cooling parameters: the cooling water temperature shall be ≤35℃, the working water pressure is 0.1‑0.4MPa, and the water flow rate is 0.2‑0.6m³/min.
The housing reaches IP65 ingress protection grade. Standard configuration includes 1 set of air & water-cooled housing, 1 semi-fixed pan-tilt, 1 stainless steel bracket and 3 metal hoses. A vortex cooling tube is optional.
It supports various CCD color and black-and-white cameras and 3× varifocal lenses (cameras and lenses are optional). The mounting method supports semi-fixed pan-tilt and 15kg motorized pan-tilt installation.
High-temperature protective enclosures are primarily used to protect equipment or components from heat damage in high-temperature environments. They utilize air-cooling and water-cooling systems to dissipate heat. These enclosures are suitable for protecting electronic devices such as cameras and sensors operating in extremely high-temperature environments, such as high-temperature camera protection in steel smelting workshops and other high-temperature settings.
In high-temperature operating environments, these enclosures automatically adapt to fluctuating ambient temperatures and provide continuous cooling, ensuring stable operation. Their dual-cooling function effectively safeguards the safety of workers and monitoring equipment in high-temperature conditions.
They protect against contamination from dust, impurities, and corrosive gases, while also providing vandal-resistant protection tailored to the installation site.
Application Scenarios: Dust-prone areas, spray zones, oil-contaminated areas, corrosive zones, and combustion zones in industries such as metallurgy, building materials, power generation, steel, glass, and solid waste management.

Designed and customized according to customer requirements; a wide range of customized products is available.
Strong Sealing; High Safety Factor: Minimizes interference from external factors and extends the service life of electronic equipment.
The product’s protection rating typically reaches IP56, and the viewing window is made of clear, transparent safety glass. It offers excellent water resistance. For cameras
Lightweight; Easy Installation; Simple Maintenance
The protective enclosure weighs approximately 2.2–5.5 kg and can support a load five times its own weight. It features a slide-out or flange-connection structure, with the electronic monitoring equipment secured to a “rail support plate” within the assembly; the front-to-back position can be adjusted according to the size of the monitoring equipment. Cable exits use compression nuts to prevent cables from being pulled out; terminal blocks are installed on the rails to facilitate wiring of internal electronic components when needed. Power cables are routed out through two connectors in the rear cover assembly, facilitating installation and maintenance;

Selection and Classification of Protective Enclosures
When selecting a protective enclosure, the following points should be considered based on the installation method and intended application:
1) Installation location and operating temperature: The optimal operating temperature range for a camera is 0°C to 30°C; temperatures outside this range may affect image quality or cause damage.
Selection must account for high- and low-temperature environments, including wind, rain, snow, cold temperatures, dust, and fire.
2) Size Selection: The housing size should be larger than the combined dimensions of the camera and lens; otherwise, the camera and lens will not fit inside.
3) Power Supply: Select a housing with a wiper function and use a decoder or relay to control it.
