Neodul®

Amazing properties. Higher energy efficiency with 30% less heat losses and therefore better energy class.
Individual solutions. Every product is alligned to a specific tank.
Top quality. Stable in visual appearance, endurance and insulation.
Technology of today, solution for tomorrow. We constantly innovate to meet the standards of the future.

The innovative product Neodul® is establishing itself as the new standard for the thermal insulation of hot water tanks. The lagally protected combination of individual material layers reduces the heat losses compared to other types of insulation significantly. Energy costs will thus be radically lower.

The insulation is easy to assemble thanks to its clever design (including holes for the connection pipes and their insulation). The insulation is stable and fits perfectly to your individual tanks. The assembling is simplified by its low weight and the use of a closing slat or a zip fastener. The installation can be done quick and easily by one or two people.

Thanks to the rigid material, the Neodul® insulation is not sensitive to mechanical damage of the cover, which is typical for soft insulation.


Thermal insulation properties

The thermal conductivity of expanded polystyrene with graphite nano particles is lower than 0.032 W/mK, while general insulation materials like polyester fibre fleece and polyurethane soft foam usually reach approximately 0.040 W/mK. This properties combined with the high fitting accuracy makes the Neodul® insulation much more efficient compared to comparable products. Neodul® products have up to 30 % lower thermal losses in comparison with conventional insulating materials.

Energy classes

While general insulation materials lead to a classification between class E and class C, Neodul® can help you to achieve class B for all tank volumes up to 2000 litres. Even class A can be achieved with tanks up to 500 litres by using a Neodul® insulation.

Description

1 The Neodul® thermal insulation is based on polystyrene foam with admixture of graphite nano particles. The main benefit of the graphite is the heat reflection, which improves the overall product specification. The insulation is shaped as flat boards for easy transportation and storing. Rounded shapes can be formed during installation thanks to slits that provide flexibility and enable easy bending.
2 The soft wool offers high adherence, which eliminates unwanted thermal losses caused by thermal convection (vertical flow).
3 Insulation edges are soft and flexible and make installation a very easy and comfortable experience.
4 The top layer in all types can be manufactured in any colour or custom printed. Neodul® professional & plus versions are supplied with a protective covering film or with a fine embossed pattern.
5 Top part insulation and its plastic cover are included. Insulation from the floor can be provided upon request.

Sustainability, ecology

During the production of our products we focus on quality and sustainability. Our production is managed by quality standards of ISO 9001 (Quality Management) and ISO 14001 (Environment Protection). In the utilization phase our products maintain their properties through out the whole life cycle, especially concerning thermal conductivity, unlike other insulation materials like polyurethane rigid foam.

At Greiner PURtec, sustainability, environmental friendliness and the highest quality go hand in hand.

Environmentally responsible companies enjoy higher respect of clients, governments and other companies. The Neodul® transportation leads to significantly lower CO2 emissions compared to other insulation concepts, thanks to the low weight and the dimensions. It is easy to be responsible by using our solutions.

Neodul® plus differs from the professional version by pressure-activated glue inside the slits. The ideal adheasion is achieved as quickly as in approximately half a minute. The product can be formed into the required shape during this time. Thanks to this, the installation is extremely simple and can be easily carried out by one person without any special tools or supporting fixtures. This way we save your time and money. The outer layer is fixed the same way as in the professional version.

The Light version is equipped with a flexible top layer unlike other models that feature a hard one. A classical zip fastener is used for closing. Thanks to this, the insulation reaches a favourable weight. This version also features a solid EPS - graphite core. The insulation thus keeps its high quality and minimizes the risk of damaging. The price-to-performance ratio is unique when compared with typical products on the insulation material market.
