Global Proof CRL150: Heat-Resistant Housing for Surveillance Cameras

In modern industrial environments, the need for robust video surveillance systems capable of operating under extreme conditions is becoming increasingly critical. Facilities such as steel plants, oil refineries, and power stations require continuous monitoring of processes conducted at ambient temperatures ranging from +200°C to +600°C.

Global Proof introduces the CRL150 thermal enclosure — an engineered solution designed to safeguard video equipment in environments characterized by high thermal loads, corrosive chemicals, and intense mechanical stress.

Engineering Features and Materials

Structural Strength and Corrosion Resistance

The core of the CRL150 is a housing made of austenitic stainless steel AISI 316L, containing 2–3% molybdenum to ensure outstanding corrosion resistance. With 3.5 mm thick walls and double-welded seams subjected to radiographic inspection, the design maintains structural integrity under substantial thermal stress. The material’s mechanical properties are notable: a yield strength of 170 MPa and a Brinell hardness of 217 HB.

All fastening components — bolts and screws — are also made of stainless steel, preventing galvanic corrosion and ensuring secure, long-term connections between parts throughout the product’s operational lifespan.

Hybrid Cooling System

The enclosure is equipped with an innovative dual-chamber system that supports both liquid and air-based cooling methods:

Protection Ratings Against External Factors

The CRL150 complies with IP66 standards, providing complete protection against dust ingress and powerful water jets. Sealed PG13.5 cable glands ensure secure retention and insulation of electrical connections. Depending on the configuration, the enclosure can meet IP68 standards, allowing for use in conditions involving prolonged submersion.

Optical Characteristics and Video Equipment Compatibility

Versatile Integration

The internal usable space of the CRL150 measures 78×77×300 mm, accommodating a wide range of cameras with lenses up to 95 mm in diameter and a maximum weight of 2.5 kg. Four M6 mounting holes ensure secure attachment of the installed equipment.

Specialized Optical Components

The standard 90 mm glass window withstands temperatures up to +300°C, while the optional high-temperature VHF150 glass extends this range to +600°C, maintaining over 90% optical transparency.

For specialized applications involving thermal imaging cameras, dedicated filters are available:

An optional IR filter for night surveillance (650–1100 nm) is available, enhancing system functionality in low-light environments.
