Heating Systems & Temperature Control

Thermal Oil Heating

Indirect Heating: Thermal oil circulates through internal heating coils to transfer heat to the stored bitumen.

Temperature Management: Heating controls and temperature sensors can be specified to monitor operating conditions and help prevent unintended overheating.

Electric Heating

Electric Heating Elements: Heating elements can be selected according to the required heating duty and available electrical supply.
Dry-Well Configuration: Dry-well elements may be specified where the design allows inspection or replacement without draining the tank.
Electrical Controls: Power distribution, temperature regulation, over-temperature protection and electrical safety devices are defined according to the project design.

Heating System Selection

The appropriate heating method depends on the required operating temperature, initial bitumen temperature, heating-up time, ambient conditions, tank capacity and available utilities. Heating capacity should be calculated from the actual project requirements rather than selected by tank volume alone.

Applications & Configuration Options

Asphalt Mixing Plants
Storage tanks supply heated bitumen to asphalt production systems. Tank capacity and heating duty should be coordinated with plant output, binder consumption, delivery schedules and the required operating temperature.
Bitumen Terminals & Storage Yards
Larger storage configurations can be specified for bulk bitumen receiving, storage and transfer. Tank arrangement, inlet and outlet connections, pump interfaces and site infrastructure should be reviewed together.
Polymer-Modified Bitumen (PMB)
For SBS-modified and other polymer-modified binders, agitation, circulation and temperature management may be required to control storage conditions. The appropriate arrangement depends on the binder formulation, storage duration and supplier's processing recommendations.
Project-Specific Configurations
Insulation & Cladding: Specified according to ambient conditions, temperature requirements and outdoor exposure.
Heating & Piping: Coil arrangements, heated connections and transfer-line provisions can be defined in the engineering drawings.
Instrumentation: Level, temperature, alarm and control requirements can be matched to the plant's operating system.
Access & Maintenance: Manholes, inspection openings, ladders, platforms and lifting provisions can be included where required by the design.

Frequently Asked Questions

Q: How do I choose between a horizontal and a vertical bitumen tank?

A: A horizontal tank may suit sites with sufficient ground length or relocatable plant requirements. A vertical tank may reduce ground-space requirements for permanent installations. The final choice depends on usable capacity, foundation conditions, installation access and site layout.

Q: Should I choose thermal oil heating or electric heating?

A: Thermal oil heating is suitable where a compatible thermal oil system is available or can be supplied. Electric heating may suit installations with adequate electrical capacity. The decision should consider heating-up time, energy availability, operating temperature, control requirements and maintenance access.

Q: Can the tank be used for SBS-modified bitumen?

A: Potentially, provided the tank, heating arrangement and any agitation or circulation system are suitable for the specified binder. The required storage temperature, viscosity, storage duration and mixing requirements should be confirmed before selecting the configuration.

Q: Can the tank connect to an existing asphalt plant control system?

A: Yes, integration can be evaluated using the existing plant's PLC, I/O list, sensor requirements and communication protocols. Compatibility should be confirmed before the electrical and control configuration is finalized.

Q: What quality documents can be supplied?

A: Depending on the agreed scope, documentation may include material certificates, dimensional inspection records, welding and NDT reports, heating-coil test records, coating inspection reports and final inspection documentation.

Q: What information is needed for a quotation?

A: Please provide the required capacity, tank orientation, bitumen grade, operating temperature, heating source, available utilities, site dimensions, required instrumentation, applicable design code and destination port. Drawings and project specifications are helpful when available.
