Profile
 More than 35 years HTI-GESAB Hoch-Temperatur Industrieanlagen GmbH is successfully manufacturing and delivering Thermal Oil-Heater plants for ship building and industry.
In 1967 HTI Hoch-Temperatur Industrieanlagen, has been established as a single company. In 1971 the company grew from engineering office - headquarter Hamburg - to a production plant in Ellerau before the gates of Hamburg. In 1981 HTI changed into GmbH (private limited company - plc).
In July 2001 the enterprise cooperate with the License partner Gesab Göteborgs Energy Systems AB and created HTI-GESAB Hoch- Temperatur Industrieanlagen GmbH as a new society.
Today HTI-GESAB Hoch- Temperatur Industrieanlagen GmbH are a highly motivated team with headquarter in Germany, as well as a agencies in Sweden and China.
In Ellerau is the manufacturing of heater up to a single weight of 25 t with a cacity of max. 10.000 kW and on inquiry bigger than that.
Up to now, HTI-GESAB Hoch- Temperatur Industrieanlagen GmbH has deliver more than 700 heater plants for marine operating and more than 600 land plants, which distinguishes our cometence and our know-how in this area.
The traffic-favourable location of the HTI GESAB Hoch- Temperatur Industrieanlagen GmbH to the BAB A7 and to the airport Hamburg ensures a fast and reliable service.
Field of possibilities for thermal oil plants
General:
Thermal oil plants on the basis of mineral heat carrier oils or synthetic heat carriers can be employed in industrial, technological heat processes which require temperatures between 120 °C and 400 °C.
Advantages:
The advantages of thermal oil plants, contrary to steam plants, are:
• plants work almost unpressurised or plants with synthetic heat carriers work with low steam pressure respectively
• maintenance of heat carrier similar to water processing for steam boiler plants, is not needed
• corrosion of boiler plants, pipe line systems, heat exchangers in consumer and at armatures is excluded, due to the anti-corrosion characteristics of heat carrier oil
• possibilities of heating as well as cooling with same heat carrier if an adequate plant unit is available
• due to qualities of heat carrier it is guaranteed that even with erections out of doors and temperatures below zero, no freezing of heat carrier will occur.

WHY THERMAL OIL
There are two different media to use for practical heating applications:
THERMAL OIL and STEAM/HOT WATER
