Blue doorframe automatic door with maintenance-free motor
Full-featured , easy to use automatic sliding door technology - reflect the perfect combination of the safety and accuracy .
STD420 control system is very intelligent : it can be auto-adjust drive force by leaf weight to make leaf run stably . speedy and smoothly ,specially fit for heavy transit entrance such as bank , hospital ,opera house and so on .
It is special double track can avoid leaf degress . The battery( within standard part ) can open the door even on power failure .
The operator box can tune mode and preferences . STD420 can expand to interface with many kind of sensor and control device .

HC-134A is a hydrocarbon refrigerant blend. The primary ingredients are hydrocarbons, which are flammable substances such as propane and butane. HC-134a is available in 30 LB cylinders. Automotive refrigerants that leak out of A/C systems contribute very little to the overall global warming problem.
The U.S. EPA has issued regulations that call for R134a to be phased out of domestic new car production by 2021. R134a will still be allowed for certain export vehicles, but only until 2025. After that, all new vehicles will have to use HC-134A refrigerant. HC-134A is flammable, but the new refrigerant is safe for automotive passenger car use. The risk of fire is extremely remote in case of an accident or refrigerant leak into the passenger compartment.
Application: Replacement refrigerant of R134A.
