Introduction
Global has been a mark of distinction in the die-cast aluminium radiator industry for thirty years, known for quality and guarantee. The unique properties of aluminium allow for innovative styling, combining linear sensitivity with subtle curves for practical and space-saving designs.

Specifications
The radiators are made from certified alloy EN AB 46100, known for performance and efficiency. They feature advanced pre-finishing technology with stove enamelling for a durable and luxurious finish. The KLASS range combines technology and aesthetics with longevity and high performance.

Guarantee
GLOBAL radiators come with a ten-year guarantee from the date of manufacture, covering replacement of elements with manufacturing or material defects, provided installation complies with suitable regulations.

Thermal Power Calculation
To calculate radiator thermal power (P) with different ∆T from ∆T 50°C, use the equation: P=Km · ∆Tⁿ. For example, the KLASS 600 model with ∆T = 60°C results in 168 Watts.

Installation Guidelines
KLASS radiators can be used in hot water or vapour heating installations up to 110°C with a working pressure up to 600 K Pascal (6 bar). They are compatible with iron, copper, or thermoplastic pipes. Recommended installation distances are ≥ 3 cm from the wall, ≥ 10 cm from the floor, and ≥ 10 cm from shelves or window-sills. To avoid noise from thermal expansion, use plastic sleeves on brackets.

Maintenance Recommendations
To prevent corrosion and deposits in mixed metal systems, maintain water pH between 6.5 and 8 and use an inhibitive additive like Cillit-HS 23 Combi. Install floating automatic or manual air vent valves for efficiency. Avoid installing radiators in permanently wet environments to protect the paint surface.

Model Specifications
The document provides detailed specifications for various KLASS models, including dimensions, weight, water content, and thermal powers at different ∆T values.

Accessories
A range of accessories is available, including brackets, reduction kits, air vent valves, and more, to support installation and maintenance.

Color Options
Radiators are available in standard colors like white (RAL 9010) and special colors such as ivory, grey, beige, lilac, dark grey, silver grey, and rust brown.
