About the melting terminals

At the end of the supply chain, the bitumen has to be re-liquefied for final application. This is accomplished by the Pörner High-Performance Melting Unit (HPM), which is the central element of a Melting Terminal.

The Melting Terminals substitute depots and bitumen terminals and are a cost-effective alternative to expensive conventional infrastructure with a small one-time investment. Instead of heated tanks or inefficient drum decanters, the Melting Terminal only requires a flat, compacted storage area and at least one HPM.

The HPM is probably the most efficient bitumen melting facility and has been designed by Pörner process engineers. Its central component is a melting grid with high-tech heat distribution and heat recovery. It can be operated by just one person. It requires either form of energy available, e.g. Diesel, paraffin or gas. Consumption is as low as four liters of Diesel (or energy equivalent) per melted ton of bitumen, depending on ambient temperature.

Layout of a typical melting terminal

Area required (min.; typical) 3,000 sqm
Manpower requirement (recommended) 3-5 per shift, depending on capacity and location
Environmental impact Usually none: No exhaust fumes visible, bitumen is non-hazardous and food-safe.
Plant capacity (turnover; typical) 2,000-3,000 metric tons per month


  1. Small one-time investment
  2. Little maintenance requirements of equipment
  3. Low manpower requirement
  4. Setup a depot quickly in other places, where needed (e.g. close to a large project construction site)
  5. Relief the end-user from bitumen logistics
  6. Melt and deliver on demand and just-in-time
