Can I use EX db eb II B T4 Gb motors in an API centrifugation room with solvents?

[SF6-146]

Hello everyone,

I’m working on a project involving the centrifugation of APIs where solvents are used. The centrifugation room is equipped with a ventilation system that provides 10 air changes per hour.

I have two motors that I plan to use for the centrifuge's hydraulic and cooling systems, and they are classified as EX db eb II B T4 Gb. Additionally, there is an electrical panel with the classification II 2G EX ia ib IIC T6 Gb.

My question is: Would you consider this centrifugation room to be classified as Zone 0 or Zone 1 according to ATEX regulations? And based on this classification, is it appropriate to use these motors in this room?

I would greatly appreciate any insights or experiences you can share.

Thank you!

Zone 0 – Ignitable concentrations of flammable gases or vapors are present continuously or for long periods of time.
Zone 1 – Ignitable concentrations of flammable gases or vapors are likely to exist under normal operating conditions or may exist frequently due to repair, maintenance, or leakage; or equipment is operated in a manner that equipment breakdown or faulty operation could result in the release of ignitable concentrations of flammable gases or vapors and cause failure of electrical equipment such that the electrical equipment becomes a source of ignition; or the area is adjacent to a Zone 0 location from which ignitable concentrations of vapors could be communicated.
Zone 2 – Ignitable concentrations of flammable gases or vapors are not likely to occur under normal operating conditions, and if they do, will be present for only a short period of time; or volatile flammable liquids, gases, or vapors are confined within closed containers or systems and can escape only as a result of an accidental rupture; or volatile flammable liquids, gases, or vapors are normally prevented by positive mechanical ventilation, but may become hazardous due to system failure; or the area is adjacent to a Zone 1 area from which ignitable concentrations of flammable gases or vapors could be communicated.
