Drum and IBC heating: four methods compared
Bitumen, paint, glucose, resin, heavy oils and gelatine must reach a workable viscosity before they can be processed or pumped. There are four ways to get there — and the right one depends less on the material than on whether the container moves and whether you need to heat up once or hold temperature all day.

Heating up or keeping warm?
The two jobs look alike but need different systems. Heating up brings a cold or solid material to process temperature — a time-limited job whose energy depends on mass, specific heat and temperature rise. Keeping warm stops a material that is already at temperature from cooling — a continuous job whose power depends on heat loss through the surface, so insulation decides the result.
In practice: to heat up, power matters and a jacket or oven is the right tool. To keep warm, insulation matters — an uninsulated tank loses the energy no matter how much power you install. Most plants need both: bring the material to temperature in the morning and hold it there all day. Size the power for heating up, and the insulation for holding.
The four methods
1 · Heating jacket (FlexMax) — removable
Wrapped around the container, fastened with straps and taken off when the job is done. It works where the container stands, takes no floor space and one jacket can serve several drums in turn — the right choice for containers that move, rotate or change often. FlexMax jackets are made for 19 L buckets, 120 L canisters, 200–220 L drums, 1,000 L IBC totes and gas cylinders; pipe and valve jackets belong to the same family.

- IBC tote heater jacket, 1,000 L
- Canister jacket, 120 L · bucket jacket, 19 L · gas cylinder jacket
2 · Heat tracing cable — permanent
Heating cable is laid on the tank wall or along the pipeline, covered with insulation and stays there. It is the method for fixed storage tanks, silos and process lines: it follows any geometry, covers the whole line and suits continuous operation. See tank heat tracing and our heat tracing guide.
3 · Drum oven and heating cabinet — batch
Containers go inside; fan-driven air heats them all evenly. Choose this when several drums or IBC totes must be heated at once, when the target is above what a jacket can reach, or when there is a continuous flow. Electric models reach 150 °C, steam and thermal-oil models 120 °C. Standard drum ovens hold 1–24 drums (electric E series, steam S series); the drum heating cabinet takes a single 200–220 L drum up to 120 °C. Larger capacities are built as project-based warming rooms.
4 · Base plate and band heater — local
Heats one zone, not the whole container. The base heater sits under a 200 L steel drum and heats from the bottom; a band heater heats a strip of the drum wall at high power. When the goal is flow at the outlet rather than heating the whole content, this is the most economical method. Band heaters work from 20 to 150 °C and up to three can be combined.
The four methods side by side
| Feature | Jacket | Heat tracing | Oven / cabinet | Base / band |
|---|---|---|---|---|
| Container | Portable | Fixed | Portable | Portable |
| Removable | Yes | No | — | Yes |
| Insulation | Built in | Installed separately, required | Built in | None |
| Containers at once | 1 | Along the line | 1–24 | 1 |
| Heated zone | Whole body | Where laid | Whole container | Base or strip |
| Continuous duty | Medium | High | High | Medium |
| Floor space | None | None | Yes | Little |
| Warranty | 2 years | 2 years | 2 years | 2 years |
A plant usually uses more than one: heat tracing on fixed storage tanks, jackets on drums going into production, an oven for seasonal batch work. They are not alternatives but answers to different tasks.
Typical process temperatures
| Material | Typical temperature | Sector |
|---|---|---|
| Olive oil | 30–40 °C | Food |
| Syrup, molasses | 35–45 °C | Food |
| Honey | 40–45 °C | Food |
| Chocolate | 45–50 °C | Food |
| Engine oil | 40–50 °C | Automotive |
| Epoxy | 40–50 °C | Chemicals |
| Resin | 50–60 °C | Chemicals, paint |
| Glue | 55–65 °C | Adhesives |

Heat-up time and energy by container
| Container | Method | Heat-up (h) | Energy (kWh) |
|---|---|---|---|
| Bucket | Jacket | 1 | 1.2 |
| Bucket | Base plate | 0.5 | 0.8 |
| Canister 60 L | Jacket | 2 | 2.8 |
| Canister 120 L | Jacket | 3 | 4.5 |
| Drum 200 L | Jacket | 4 | 6.5 |
| Drum 200 L | Heating cable | 5 | 7.2 |
| Drum 200 L | Base plate | 3 | 5.5 |
| IBC 1,000 L | Jacket | 8 | 12.5 |
| IBC 1,000 L | Heating cable | 9 | 14.2 |
| IBC 1,000 L | Oven | 5 | 9.5 |
Times are for a full container at 20 °C ambient without extra insulation. With insulation, both time and consumption drop noticeably.
Rules that apply to every method
Plastic containers: 60 °C ceiling. For HDPE drums and IBC totes the manufacturer limit is 60 °C maximum filling temperature and 49 °C continuous. Above that the container softens. If you need more, transfer the material to a steel container or use an oven — more jacket power is not the answer.
Closed containers build pressure. Warming contents expand; vent the container while heating. Heating a tightly closed drum is not safe.
Residual current protection is mandatory. Heating jackets are double insulated, but every installation must be fed through a residual current device (RCD). In hazardous (Ex) areas, antistatic and ATEX-rated products are required — a standard jacket is not suitable there.
Frequently asked questions
Drum heater jacket or heat tracing cable?
If the container moves, use a jacket; if it is fixed, use cable. A jacket moves from drum to drum and installs in minutes; cable is permanent, installed together with insulation and better for continuous duty.
Which materials are heated with these systems?
Bitumen and bitumen emulsion, paint and varnish, resin and glue, glucose and molasses, honey, vegetable and mineral oils, gelatine, soap and surfactants, polyurethane raw materials. Each has its own target temperature and degradation limit.
Is insulation required?
For heat tracing, yes. Jackets and cabinets have insulation built in. Cable on a fixed tank without insulation heats the surroundings, not the material.
Does the system run all the time?
No. The thermostat switches off at the target and back on below it. When keeping warm, the quality of insulation decides how many hours a day it runs.
Can it be added to an existing plant?
Yes. Jackets fit immediately. Heat tracing can be laid on an existing tank; the insulation is removed and reinstated after the cable is in place.
Do you make custom sizes?
Yes. We size the power from tank volume, material, target temperature, ambient conditions and existing insulation. Custom jackets are made in our Edremit (Balıkesir) workshop, ovens in İzmir and cabinets in İstanbul.
