UL Sprinkler Rain Test Apparatus

The UL sprinkler rain test apparatus is the dedicated Test apparatus for performing the Sprinkler Rain Test in the UL 50E standard. This standard is mainly applicable to the protection grade test of electrical equipment enclosures, especially those used in outdoor environments, to ensure that they can maintain functionality and safety under conditions similar to rainfall.

 

Model:  R-UL020

Standard: UL 50E

UL Sprinkler Rain Test Apparatus Features and Benefits

1. The parameters such as spray intensity, pressure and distance fully comply with the UL 50E Type 3R test requirements. Applicable to the testing of various electrical enclosures that require UL certification.

 

2. Multi-nozzle layout ensures that the entire sample is evenly sprayed from all angles. Large-sized control cabinets, small test pieces, and sprinkler water flow can all simulate the function of real rainwater or fire extinguishing systems.

 

3. The high-performance water pump system and pressure/flow sensor can precisely set and dynamically monitor the test water pressure (such as 30 psi) and flow rate. It has high repeatability and consistency

 

4. Made of 304 stainless steel, it features excellent rust prevention and corrosion resistance, making it suitable for long-term high-humidity working conditions. It can also be equipped with a splash-proof shield.
