Thermal insulation for brass manifolds IVAR.AC 652 – 5/4", 12 outlets
Code: 506254Product detailed description
The IVAR.AC 652 insulating cover in size 5/4" fits over brass bar manifolds and over sets comprising both a flow and a return manifold with a 5/4" main connection. It is made for 12 outlets and is used in radiant heating as well as cooling systems.
What it is for
In cooling mode the manifold surface is cold and, without insulation, moisture condenses on it. The polyethylene cover prevents condensation from forming. In heating systems it may be used up to a maximum temperature of 85 °C.
Two material layers
- inner layer: density 30 kg/m³, thermal conductivity 0.041 W/mK at 40 °C, water absorption below 1 % in 24 h, dimensionally stable up to 85 °C
- outer layer: density 80 kg/m³, thermal conductivity 0.049 W/mK at 40 °C, dimensionally stable up to 105 °C
- both layers: fire reaction class B2, water vapour diffusion resistance factor μ 1300
According to the manufacturer, the cover is not classified as a hazardous product. It may become electrostatically charged by friction during handling. Separate codes of the AC 652 range are available for manifolds with 1" and 6/4" connections.

Frequently asked questions
Which manifolds is the IVAR.AC 652 5/4" insulation designed for?
For brass bar manifolds and flow/return manifold sets with a 5/4" main connection, in the 12-outlet version. For 1" and 6/4" connections, a different code of the AC 652 range is ordered.
Is the insulation also suitable for cooling?
Yes, the manufacturer specifies it for radiant heating and cooling. In cooling it stops condensation from forming on the cold manifold.
Up to what temperature can the insulation be used in heating?
In heating systems up to a maximum of 85 °C. The inner layer is dimensionally stable up to 85 °C, the outer layer up to 105 °C.

IVAR designs, develops and manufactures highly energy-efficient heating and plumbing systems. We have over 10,000 catalogue items - mass-produced products and unique items - in addition to customised systems and combinations of complex products. And it’s all “Made in Italy”.
Vision
To make life easier for our clients, our clients' customers and our employees, thanks to our ability to be constantly innovative.
Mission
To design and manufacture advanced hydronic solutions that reduce installation complexity and energy consumption.
“Made in Italy” adds value
IVAR has been producing heating and plumbing system components since 1985: valves for heating bodies, direct heat metering modules, heat cost allocators, pipes and fittings, substations for heating systems, distribution manifolds, radiant panel systems, and components for solar and geothermal systems. And it’s all “Made in Italy”.
Over 200 people are employed at our manufacturing facilities in Prevalle (in northern Italy’s Brescia province). The site has been designed to streamline our many production and operational stages.
The Italian headquarters also acts as a hub for the wider IVAR Group, set up with the goal of distributing products beyond Italy’s borders. The group now has 11 branches, in Australia, Belgium, China, Germany, the United Kingdom, the Czech Republic, Romania, Slovakia, Spain, the United States and Tunisia.
Know How
Research, development and numerous laboratory tests guarantee that our clients’ requests can be translated into new high-efficiency products.
The stages required for production take place internally, beginning with hot forming, which is carried out at our subsidiary Valmon Stampati. Our continuous implementation of projects under the Industry 4.0 initiative also allows us to take full advantage of new releases in technology and IT to improve our manufacturing efficiency.
As a company, IVAR is constantly evolving. Every day, we invest in strengthening our products, in improving our production processes and in attaining new patents and certifications.
