NVENT HOFFMAN PLCSKIT Leak Compensation Service Kit

Why Choose the nVent HOFFMAN PLCSKIT Leak Compensation Service Kit?

The nVent HOFFMAN PLCSKIT is a dedicated purge and pressurization leak compensation service kit for maintaining nVent HOFFMAN leakage-compensation purge systems used with industrial electrical enclosures. Part of the nVent HOFFMAN HLP range, it provides a manufacturer-specified service solution for purge and pressurization equipment protecting electrical and electronic components in hazardous-location applications.

Leak compensation purge systems maintain positive pressure inside an enclosure by replacing protective gas lost through normal enclosure leakage. This positive pressure helps prevent potentially explosive gases or dust in the surrounding atmosphere from entering the enclosure. The PLCSKIT supports servicing of this leak compensation system architecture, helping maintain reliable purge and pressurization performance.

nVent HOFFMAN leak compensation systems are designed for use with Type 4, 4X and 12 enclosures, with IP54 recommended as the minimum enclosure protection level. The associated systems operate with a dry, clean air or inert gas supply of 60–115 psi (4–8 bar) and across an ambient operating temperature range of -20 to +55 °C, making the PLCSKIT relevant to demanding industrial and hazardous-area maintenance applications.

Maintaining Leak Compensation Purge and Pressurization Systems

Purge and pressurization is used to help protect electrical equipment operating in hazardous locations. The enclosure is initially purged to remove potentially explosive gases or dust and is then maintained at a positive internal pressure using clean air or an inert gas. In a leak compensation system, protective gas is supplied as required to compensate for normal pressure losses and help prevent the surrounding hazardous atmosphere from entering the enclosure.

Maintaining purge and pressurization equipment correctly is important to the integrity of the overall protection system. The nVent HOFFMAN PLCSKIT provides a dedicated service-kit solution for compatible leak compensation equipment, helping maintenance teams and system integrators service the purge system using manufacturer-specific components rather than general-purpose alternatives.

• Maintenance of nVent HOFFMAN leak compensation purge systems.
• Hazardous-location electrical enclosures.
• Industrial control and automation panels.
• Oil and gas processing installations.
• Petrochemical and chemical processing equipment.
• Process instrumentation systems.
• Manufacturing facilities with potentially explosive atmospheres.
• Preventive maintenance of purge and pressurization equipment.
