Fuel Testing Regulations, Requirements and Parameters Medical, Emergency / First Response, Senior Care / Assisted Living, Data Centers, Airports, Communication, Transportation, and Energy companies, all must test fuel annually. Joint Commission Requirement on Fuel testing: EC.02.05.07-8, The National Fire Protection NFPA 110 2010 requires at least annually a fuel quality test in accordance with “approved… Read more »
Coalescer Technology (What’s True & What Fails in the Field)
Condensed Technical Analysis: Coalescer Claims vs. Dieselcraft Fuel Purifier Hydrophilic coalescer membranes do attract water and allow diesel to pass, causing droplets to merge and fall out by gravity. But they only remove free and emulsified water — not dissolved water. The widely advertised “99.99% water removal” is a marketing claim, not a field verified… Read more »
Hospitals and Care Facilities must document this testing to maintain accreditation.
📌 What the Joint Commission Actually EnforcesThe Joint Commission’s Environment of Care (EC) and Physical Environment (PE) chapters reference NFPA 110 for emergency power systems.NFPA 110 requires: Generator test logs (monthly, annual, triennial)Joint Commission surveyors frequently cite missing or undocumented fuel testing as a deficiency. Annual fuel test results Corrective actions if fuel fails Sampling… Read more »
Chemical fuel additives don’t actually remove water from diesel.
Chemical fuel additives don’t actually remove water from diesel the way mechanical systems do. They only manage water through two opposite methods: emulsifying it or separating it. 1. Emulsifiers / Dispersants (“Water Removers”) These break water into microscopic droplets and suspend them in the fuel. The water then passes through the system and is burned… Read more »
What Are Diesel Tank Water Absorbers?
A diesel tank water absorber is a simple, passive device placed inside a fuel tank to physically soak up and trap water so it can’t mix with your diesel, cause corrosion, or damage injectors. Think of it as a specialized absorbent “sponge” engineered to capture a specific amount of water and then be removed and… Read more »
What is the difference between Fuel Polishing and Fuel Maintenance?
Fuel polishing and fuel maintenance are related concepts in the context of stored fuels (especially diesel), but they differ in scope, frequency, and approach. These terms are most commonly used for backup generators, marine vessels, emergency power systems, or any application where fuel sits in tanks for long periods and can degrade. What is Fuel… Read more »
Use Biocides Judiciously—Don’t Rely on Them Routinely
Eliminate water first (the primary enabler of microbial growth—”diesel bug”). Use water separators, polishing systems, or tank drainage. Reserve biocides for active infections: Apply at maximum recommended strength to eradicate the problem, then discontinue routine use. Biocides are often halogenated and corrosive—overuse risks damaging components like seals, pumps, and injectors. https://dieselcraft.com/portable-fuel-polishing/
Problems Caused by Water in Diesel Fuel
Water is widely regarded as the #1 enemy of diesel systems. Even small amounts—especially free water—trigger a destructive chain reaction that affects tanks, fuel lines, pumps, injectors, and the engine itself. In essence, water doesn’t just sit harmlessly—it creates a snowball effect of degradation, especially in stored, standby, or infrequently used systems (generators, marine vessels,… Read more »
How Water Gets Into Diesel
Water contamination is one of the most common and damaging issues in diesel fuel storage and use. Diesel—particularly modern ultra-low sulfur diesel (ULSD) and biodiesel blends—is hygroscopic, meaning it naturally attracts and absorbs moisture from the surrounding air at a molecular level. This makes water ingress almost inevitable over time, especially in stored fuel. Water… Read more »
Results Of U.S. Navy Tests On Magnetic Fuel Conditioning Technology
The U.S. Navy conducted formal testing on magnetic fuel conditioning technology using heavily aged #2 diesel fuel. The tests involved recirculating the fuel through a fuel polishing system. This integrated system combines mechanical filtration with magnetic fuel conditioning technology. Key results from the published Navy fuel analysis report are summarized below: MMI Engineered Systems Division… Read more »
Black or Brown Solids in My Fuel.
When biodiesel is poorly made—often referred to as “bad biodiesel”—one of the biggest red flags is a high concentration of glycerine (or glycerin/glycerol). Here’s why that matters:🧪 What Glycerine Is in Biodiesel• Glycerine is a byproduct of the transesterification process used to make biodiesel from fats or oils.• Ideally, it should be separated and removed… Read more »
