Frequently Asked Questions
Is the control panel for the SC rated NEMA 4?
What are the air requirements for operating the SC backflush valve (pneumatic)?
Does the electric gear motor on the top of the SC have any special environmental ratings?
Can the SC be located outside?
1. Is the control panel for the SC rated NEMA 4?
Yes, this is the standard electrical enclosure on the SC. NEMA 4 allows for:
• Indoor & outdoor use
• Falling liquids and light splashing
• Nonhazardous dust, lint, fibers
• Washdowns and splashing water
2. What are the air requirements for operating the SC backflush valve (pneumatic)?
For the Backflush Valve the pneumatic actuator requires 87 psi (6 bar) air supply pressure. (NOTE: This is for actuator air consumption for SC‘s with Cleaning Control System Type – Options S, P, & T)
3. Does the electric gear motor on the top of the SC have any special environmental ratings?
Yes, the motor on SC‘s with Cleaning Control System Type – Options S & E – is rated under IP55. IP55 allows for:
• 5 = Protected against dust – limited ingress (no harmful deposit)
• 5 = Protected against low pressure jets if water from all directions - limited ingress permitted
4.Can the SC be located outside?
Yes, if the environment does not go beyond what is outlined under NEMA 4 and IP55 definitions. NOTE: The SC has to be protected from freezing. This includes the main housing, gauge lines & backflush line. “Solid water has terrible viscosity”
