VpCI-Plastic Emitter  corrosion inside an electrical cabinet or control box often develops without any early warning. Moisture, salt, oxygen, dust, and industrial gases can enter through small openings or during routine maintenance. Over time, these contaminants may affect terminals, contacts, circuit components, fasteners, and other exposed metal parts.

The problem can become more serious in Qatar and Doha, where equipment may face coastal humidity, high temperatures, condensation, and long periods of storage. Applying grease or oil inside sensitive electrical equipment is not always suitable because it can attract dust and require cleaning later.

The VpCI-Plastic Emitter provides a clean and practical alternative. The VpCI-105 and VpCI-111 are compact plastic devices fitted with a breathable membrane. They slowly release Vapor phase Corrosion Inhibitors into an enclosed space, where the protective molecules travel through the air and settle on metal surfaces.

The VpCI-105 Plastic Emitter protects an enclosed volume of up to 5 cubic feet, or about 142 litres. The larger VpCI-111 Plastic Emitter protects up to 11 cubic feet, or approximately 312 litres. Both products are suitable for control panels, cabinets, toolboxes, electrical enclosures, communication systems, motors, and packaged equipment.

Nassguard supplies the VpCI-Plastic Emitter in Qatar and Doha for industrial plants, electrical contractors, marine facilities, oil and gas companies, warehouses, utilities, and engineering projects.

What is a VpCI-105/111 Plastic Emitter?

The VpCI-105/111 Plastic Emitter is a corrosion protection device designed for closed or non-ventilated spaces. It consists of a plastic cup containing corrosion-inhibiting material beneath a breathable membrane.

Once the emitter is removed from its packaging and placed inside an enclosure, it starts releasing protective vapours. These vapours spread throughout the enclosed airspace and reach exposed metal parts, including narrow gaps, corners, terminals, screws, contacts, and complex internal assemblies.

The inhibitor molecules form an invisible molecular layer on metal surfaces. This layer helps interrupt the corrosion reaction caused by oxygen, moisture, salt, sulphur gases, and other environmental contaminants.

Direct contact between the emitter and every metal component is not required. The vapour moves naturally around the equipment, allowing it to protect areas that sprays, oils, or brushes may not reach easily.

Both emitters feature a self-adhesive backing, so they can be attached to a clean, flat surface inside the cabinet or enclosure.

Manufacturing Plants

Factories can use the emitters inside machinery controls, automation systems, production panels, and equipment stored during maintenance shutdowns.

Telecommunications

The devices are suitable for communication boxes, switching systems, outdoor cabinets, and enclosed electronic installations.

Water Treatment Facilities

VpCI emitters can help protect control panels, pumping-station equipment, terminal boxes, sensors, and automation systems exposed to humid conditions.

Industrial Warehouses

Stored motors, electrical cabinets, controls, instruments, and spare parts may remain unused for months, increasing the need for corrosion protection.

Electrical Contracting

Contractors can install the correct emitter size inside switchgear, distribution boards, control panels, MCC cabinets, and junction boxes.

Export Packaging

The emitter can be placed inside a suitably sealed package to protect equipment during road, sea, or air transport.

Heavy Engineering

It can protect electrical assemblies, machine controls, fabricated equipment, and instrument panels waiting for installation or delivery.
