Electric heaters made by elwatec

OPTIMIZED FOR EVERY INDUSTRY

Electric heaters are used for heating of all liquid media as well as for evaporation of liquids.

They are used, for example, in the petrochemical and chemical industries, in the automotive, paper and cement industries, by manufacturers of lubrication systems, i.e. in all industries where the heating of liquids is required.

Electric heaters allow heating to high temperatures without significant loss of performance due to scale formation, and the temperature range can be easily controlled.

In addition, combining an electric heater with a conventional heat exchanger can open up new opportunities for use.

Manufacturing example of electric heater for liquids

elwatec designs and manufactures the following types of electric heaters:

Electric heaters for liquids

Electric heaters for liquids are most often found in heavy industry and are also used by energy supply companies.

We are designing and manufacturing the electric heaters according to customers' specifications

Working media of electric heaters

Working media of the electric heaters can be liquids or gases, such as air, nitrogen, hydrogen, hydrocarbons, argon, oxygen, etc., or e.g. the following liquid media: water, oils, thermal oils, water-glycol mixtures.

All our electric heaters can be used for heating of all flowing media as well as for evaporation of liquids, i.e. in all industries where heating of operating media is required. They can be installed anywhere: outdoors, indoors and in potentially explosive areas.

Our devices can be used for temperatures up to 1100 °C and pressure up to 350 bar. At the same time, there is no upper limit for the power (total power consumption) of the heaters.

We have repeatedly produced devices in the range from 1kW to 8000kW.

When designing electric heaters, we are guided exclusively by customer requirements.

Design codes

Electric heat exchanger could be designed, manufactured and tested by elwatec in accordance to the following design codes:

  • DGRL
  • ASME VIII Div. 1
  • CHINA-License
  • UDT
  • GOST / EAC

Others on request.

Material

Electric heaters are available in:

  • carbon steel
  • seamless steel
  • titan
  • duplex steel
  • various special steel edition

Approval according to Ex standard

Nothing stands in the way of using our products in potentially explosive atmospheres thanks to our ATEX certification.

Our devices are approved for use in explosion risk areas 1+2, gas group IIA-IIC and temperature classes T1-T6 according to the operating principle.
