Coolants for combustion engines

Coolants for combustion engines

We develop high-quality coolants with the most modern additives in our own lab. The outstanding quality of the ROWE HIGHTEC ANTIFREEZE products has been confirmed by multiple independent laboratories, distinguished by multiple OEM approvals, and fulfills international standards.

One of the world's leading providers of coolants for combustion engines

ROWE is one of the few producers of additive packs in the world, also called super concentrates, for all modern coolant technologies that are produced in the OAT plant in Worms and mixed with monoethylene glycol into high-quality coolant concentrates in Bubenheim, in accordance with the strictest quality requirements under IATF 16949. This gives us the ability to guarantee our customers and development partners leading quality and the highest future compatibility, especially in regard to ever growing thermal challenges caused by trends such as downsizing and turbo charging.

Coolants

Lab with the best equipment

In the laboratory, ROWE experts are able to check all the test criteria set out in ASTM D3306 and ASTM D4985, the most demanding standard coolant specifications in the world. In addition, we are also able to put our coolants through their paces under real-life conditions on dynamic test benches. Here we test to FFV-Heft R530, focusing on fluid properties such as corrosion protection performance, high-temperature, oxidation and storage stability, compatibility with other coolants, plastics and processing agents, cavitation protection properties and foaming tendencies.

OUR STRENGTHS

Own patents
One of the most modern laboratories for the most sophisticated tests in accordance with ASTM D3306 and ASTM D4985
Dynamic test benches simulate real conditions
Compatibility tests to compare against other coolants and components in the cooling circuit

YOUR ADVANTAGES

Highest quality and future compatibility in coolants
Individual solutions move quickly: highly efficient processes from stocktaking to formulation and sampling using existing raw materials to production

In focus: the often underestimated effect of a high-quality coolant on motor longevity

Corrosion tests in accordance with ASTM D1384

A two-week test shows the corrosion on various metals after long contact with a ROWE HIGHTECT ANTIFREEZE product (left) and another comparable product (right).

The following materials were tested (from left to right):
aluminum, iron, steel, brass, soft solder, copper.

OPTIMUM VALUES IN CORROSION PROTECTION

The table shows the maximum change in specific weight for each metal after two weeks of contact with a coolant. The limits of the standard ASTM D1384 show the maximum value in grams that a metal can gain after long contact with a coolant. Some of the ROWE HIGHTEC ANTIFREEZE products are more than 100 times below the limit, which speaks to the highest quality of our products.
