Industries We Serve
Asphalt Manufacturing
From the cold feed bins to the load-out silo, a hot mix plant runs on heat transfer fluid, gear oil, hydraulics, plant air, and grease that has to survive 300°F mix. We map the right product to every section of your plant.
Lubrication by Plant Section
Follow the aggregate from cold feed to load-out
Every section of a hot mix plant wears its lubricants differently. Here is what goes where, in the order material moves through the plant. Tap a product to jump to its details.

The Product Lineup
Ten products cover the whole plant
A short, consolidated list means fewer drums on the shelf and less chance of the wrong oil going in the wrong gearbox.

Heat Transfer System Care
The fluid that touches every tank, silo, and line
Thermal fluid runs from the heater through asphalt and additive tank coils, silo cones, jacketed lines, and valves. When it breaks down, the whole loop pays for it.
The Problem
Carbon & coke buildup
Degraded fluid lays carbon on pipe walls. That layer insulates the pipe, cuts heat transfer, and restricts flow.
- Reduces thermal efficiency by up to 30%
- Increases energy costs significantly
- Creates potential fire and safety hazards
A self-reinforcing cycle
- 1Excessive heat causes thermal cracking, breaking down the fluid's molecular structure
- 2Fouling occurs as degraded fluid deposits carbon on heat transfer surfaces
- 3Energy demand rises as the heater works harder to reach temperature through fouled surfaces
- 4The cycle repeats with higher heat exposure causing even more cracking
Already fouled? Clean, then flush.
CALFLO Cleaning Fluid

Cracking creates low boilers that drop flash point and can cause auto-ignition. Testing tells you where your fluid stands before it costs you fuel or a fire.
