Caromax^®: Aromatic solvents for tailor-made fuel additive formulations

Caromax® 20 and 28 are trusted in a wide range of fuel applications – from gasoline, diesel and aviation to marine fuels, power generation and domestic heating. As solvents, they protect active ingredients in emulsified concentrates and ensure stable, reliable formulations.

By supporting additives such as corrosion inhibitors, antioxidants, detergents, cold-flow improvers, demulsifiers and friction modifiers, Caromax® contributes directly to the performance, efficiency and durability of internal combustion engines.

Our aromatic solvents are particularly well-suited for critical components like defoamers, demulsifiers, corrosion and fouling inhibitors, as well as octane and cetane improvers, extreme pressure agents and cold-flow additives.

All Caromax® grades are available with low napthalene (LN, upto 1%) and extra low naphthalene (XLN, upto 0.01%) content.

Reliable
carrier fluids

Our Caromax® hydrocarbons act as a carrier fluid for bespoke additive formulation with the following requirement profile:

Stable quality batch to batch
High solubility for additive molecules, such as surfacant and extreme pressure additives
Long-term storage stability
Stability throughout temperature fluctuations

High-performance additives for improved environmental compatibility

At the beginning of the 1970s, exhaust emission limits were introduced, which made the automotive industry change engine concepts. The improved and therefore more demanding combustion made it necessary to avoid residues at various parts of the engine. This was achieved by using special surfactant additives. In view of the further development of engines, it is important to ensure full cleanliness even under tougher conditions. The improved cleanliness is reflected in a lower liability towards repairs, an improvement in exhaust emissions and a reduction in fuel consumption.

However, changes due to environmental regulations are not only to be found in the automotive industry. This also applies to other vessels with internal combustion engines. For example, ships are subject to much stricter environmental requirements from 1^st of January 2020. They will be only allowed to use fuels containing a maximum of 0.5% sulfur. Fuel consumption numbers must also be disclosed.

Additives and the important carrier solvents play an important role in the implementation of legal requirements and actively contribute to improving the environmental performance of internal combustion engines.

Sustainability is a decisive part of Haltermann Carless' corporate culture, to which we have felt responsible for generations. Together with our customers, suppliers and employees we want to develop and manufacture products in an environmentally friendly way, use resources in the best possible way and thus offer sustainable solutions. We are therefore working on many future projects that will make our products even more environmentally friendly.

What counts for Haltermann Carless is a consistently high quality and excellent product properties such as low naphthalene values and good solubility features. This means that the effectiveness must unfold freely in the various fuel types as well as in the most diverse combustion engines under all operating conditions. Harmful side effects have to be avoided. Product quality, effectiveness and environmental benefits shall go hand in hand.

Fuel additives require high quality solvents to work and thus improve their environmental performance.

EcoVadis Gold

EcoVadis has rewarded our sustainability approach that we embody every day at our production and operation sites.

Engagement in associations

We want to actively shape trends and be part of improvements and regulations - this is why we are involved in various associations, such as SIA (Solvent Industry Associations), ESIG (European Solvent Industry Group) and HSPA (Hydrocarbon Solvents Producer Associations).

Produktionsstandort Speyer

Dies tun wir beispielsweise an dem Produktionsstandort der Haltermann Carless in Speyer. Hier bietet unsere moderne und flexible Hydrieranlage → viele Möglichkeiten, um in Zukunft weiterzuwachsen und die steigenden Erfordernisse beispielsweise der Pharmazeutischen Industrie zu bedienen.

In der Hydrieranlage werden durch die Reaktion mit Wasserstoff die in der Rohware enthaltenen ungesättigten Kohlenstoffbindungen in gesättigte überführt. Somit können neue Produkttypen und Produkte mit einer hohen Reinheit produziert werden. Einen weiteren Vorteil bietet die Hydrieranlage in ihrer hohen Produktionsflexibilität, denn sie eröffnet neue Möglichkeiten in der Rohstoffversorgung. Dies trägt zur strategischen Stabilität des Geschäfts und zum Erhalt der Wettbewerbsfähigkeit auf dem internationalen Markt bei.
