People Electric · Positive-Pressure Explosion-Proof Cabinet
Product overview
People Electric PXK is a project-engineered positive-pressure cabinet incorporating ventilation,purge-gas control,monitoring and electrical equipment. The manufacturer requires an integrated electrical drawing and internal-equipment list for manufacture.
Technical selection summary
| Manufacturer / family | Original People Electric PXK |
|---|---|
| Rated supply | AC380V; final auxiliary/control supplies by approved electrical design |
| Manufacturer Ex marking | Expdem[ia]ia IIB T4 as printed. Confirm actual protection concept,assembly nameplate and applicable documentation; noIIC claim is made for this marked version. |
| Working pressure | 60–1000Pa as manufacturer range; actual regulator/alarm/trip settings must be established for the supplied design |
| Gas-source pressure | 0.5–0.8MPa as source; confirm protective-gas type,cleanliness,flow,consumption and supply reliability |
| Ingress / corrosion protection | IP65; WF1 |
| Documented protection functions | Purge/power interlocks; low-voltage alarm; automatic gas replenishment; high-pressure shutoff as described. Final fail-safe logic,loss-of-pressure action and permitted energization sequence require approval. |
| Internal equipment | Meters,analysis instruments,indicators,low-voltage apparatus,transducers,soft starter or computer controls may be project-specified; no device is assumed supplied by default |
| Purge / thermal design | Confirm enclosure free volume,purge flow/time,pressure supervision,heat dissipation and internal power losses for the actual installation |
| Reference outline | Manufacturer cabinet/layout drawings remain in the technical images; final dimensions and foundation/mounting depend on project design |
| Standards referenced | GB3836.1,.2,.3,.4,.5,.9 and IEC60079 as catalogue; current applicable conformity evidence must be confirmed |
The stated pressure ranges are not universal installation settings. An approved purge/pressurization design and complete internal-equipment list are required. Confirm gas supply,interlocks,purge duration,alarm/trip actions,thermal performance and current assembly conformity documentation before ordering.
Typical applications
- Project control or instrumentation cabinets using a verified positive-pressure protection system.
