Ni-Cd Battery Emergency Exit Sign
These emergency exit signs usually equipped with recharged a 3.6V Ni-cd battery inside the hosing. It has up to 500 times backup powered. The battery is protected by a low voltage cut-off circuit. Also, the emergency escape signs specialized to use the fire-resistant housing at the engineering level. Upon failure of the normal utility power, an internal transfer switch provides emergency time for at least 90 minutes. The charger initiates powered back the battery in 24 hours. The exit sign is suitable for wall or ceiling mounting. Plus, there is an indicator light and a test button on the unit so that you can periodically check that it is functioning properly.

Zhengda Shares More Insights on Honeycomb Inclined Tubes 
Discover the additional benefits of honeycomb inclined tube packing, along with technical specifications. What are the key features of honeycomb inclined tubes? What are their standard sizes and dimensions?
Honeycomb inclined tubes are widely used in sedimentation tanks for removing suspended solids and sand. Their advantages can be summarized into five main points:
First, when used in inclined tube sedimentation tanks, the treatment capacity is 3-5 times higher than that of conventional sedimentation tanks. It also improves the efficiency of clarification and pulse clarification tanks by 2-3 times, significantly reducing the required floor space.
Second, when the length of the honeycomb inclined tube is 1 meter, the effective load is designed at 3-5 tons/m², and the settling velocity (V0) is maintained between 2.5-3.0 mm/sec, ensuring optimal water quality after treatment.
Third, the amount of sludge produced is minimal, which reduces the workload in subsequent processes such as sludge dewatering. The sludge settles well, making it easier to remove suspended solids in later stages.
Fourth, the flow remains laminar, minimizing turbulence that could interfere with particle settling.
Fifth, the large wetted perimeter and small hydraulic radius contribute to better performance and efficiency.
Due to these five significant advantages, honeycomb inclined tubes have become a popular choice in wastewater treatment systems, including domestic and industrial sewage, feedwater clarification, oil separation, and more.
Finally, Zhengda provides the technical parameters for commonly used honeycomb inclined tubes:
