Pressurization system PLCF1YZ

Overview
Purge and pressurization is a protection method for enclosures (recommended minimum IP54) that removes internal explosive gases or dust, then maintains a positive internal pressure using clean protective air or inert gas. Two purge methods are provided: Leak Compensation (maintains pressure by compensating for losses) and Continuous Flow (maintains pressure by continuous protective airflow). This unit is configured for leak compensation and designed for flush mounting; certification options include Type Y and Type Z.

Features

• All exterior components in 316 stainless steel or corrosion‑resistant composite
• Space-saving flush or optional external mounting
• Local visual indicators for system and purge status
• Leak compensation models include a rapid purge valve and visual purge indicator
• Operates with dry, clean inert gas supply: 60–115 PSI (4–8 bar)
• Ambient operating temperature: -20°C to 55°C (-4°F to 131°F)
• Type X variant available with automatic purge cycle and 4P NO/20A/440VAC power contactor (115 VAC or 230 VAC coil)
