Grotamar 82

Grotamar 82 as part of controlled diesel microbial control

In the control of diesel microbial contamination, additives alone are rarely sufficient. Grotamar is a highly effective and widely accepted biocide, but its true value is achieved only when used as part of a controlled, analysis-based approach.

Why biocides are required in diesel microbial control

Once microbial growth has established in diesel fuel, tank cleaning alone is often insufficient. Microorganisms may remain in:

tank structures
piping systems
venting and filling components

Without biocide treatment, these residues can cause rapid recontamination. Effective control therefore often requires chemical treatment as part of a broader strategy.

Grotamar 82 – a powerful but demanding tool

Grotamar is designed for professional use and critical applications where fuel reliability is essential. Its use requires:

understanding of actual fuel condition
correct dosing based on contamination level
documented and responsible procedures

Improper use may result in filter blockage or operational disruptions rather than solving the root cause.

A controlled approach – not just an additive

We approach the use of Grotamar based on the following principles:

assessment of fuel and tank condition prior to action
mechanical or circulation cleaning when biomass is present
biocide use only when technically justified
documentation of all actions
ongoing monitoring of fuel condition

This approach reduces risk and improves long-term system reliability.

Grotamar as part of an integrated solution

Grotamar is not an end in itself, but part of comprehensive fuel quality management. Best results are achieved when biocide treatment is combined with:

regular monitoring
cleaning when required
preventive maintenance measures

Suspect diesel microbial contamination or considering biocide use?
The correct approach should always be evaluated case by case.
