Electric Boiler solution of Ecotherm Austria brand (used to create hot water, steam and clean steam)

PGTECH is a distributor and supplier of high quality electric boiler products of the ECOTHERM® for generating steam or hot water, fitted with sliding frame & pre-installed; in parallel with various solutions for hot water, steam and solar energy systems in a "turnkey" manner. with the world's leading advanced heat transfer technology, patented by ECOTHERM.

Conversion of electrical energy into heat is increasingly common. Due to the continuous expansion of renewable energy sources, there may be a surplus of electrical energy at certain times of the day. This excess can be converted into heat energy in the system called “Power to Heat”. If fossil fuels such as oil or gas are not available or a chimney system cannot be installed, the ideal solution is an electric heating boiler. Join PGTECH to learn about ECOTHERM's solutions for individual and turnkey electric boilers, skid-mounted or container-mounted in this article.

ECOTHERM electric hot water boiler® with heating element, up to 30 MW, skid mounted and pre-installed

ECOTHERM Electric Hot Water Boilers are used when the only available primary energy source is electricity or to convert an available surplus of electrical energy to heat in so called  “Power to Heat” systems. The electrical energy is converted to thermal energy by individual screwed type heating elements which are individually replaceable for easy maintenance. Each boiler is pre-wired, pre-set and skid mounted for quick and easy installation on site. Beside a wide range of standard models ECOTHERM is offering also individual solutions in terms of size, design, voltage, capacity and controls.

Features:

• electric boiler shell either in stainless- or mild steel
• for heating, district heating and domestic hot water generation
• power-to-heat plants
• with electrical flange heater or individual heating elements
• control panel with plant visualization, several interfaces with existing BMS (Building Management Systems)
• design and manufacturing according PED 2014/68/EC or ASME Sect. VIII Div. 1

The ECOTHERM electric hot water boiler is equipped with an industry-standard control panel with a solid metal housing. Each boiler has a main input switch as well as fuses and power contactors for each heating element. Depending on the capacity, the Hot Water Boiler is controlled by a 3-stage intelligent controller or by a freely programmable industrial microprocessor controller with touch screen HMI and exchange capability. data via BUS system or external start/stop.

ECOTHERM Electric Steam Boiler® word input 250 – 20,000kg/h, pressure up to 16 bar

ECOTHERM Electric Steam Boilers are used in hospitals or industry when the primary available energy is electricity. The steam is generated by an electric resistor heating flange inside the boiler shell. The units are skid-mounted complete with feed water tank, water treatment and control panel. The complete factory pre piping and wiring ensures quick and easy installation on site. 

Features:

• complete ready to use skid mounted for easy on site installation
• electric operation does not require gas/oil supply and chimney system
• piping and wiring factory made
• control panel with system visualization, several interfaces with existing BMS (Building Management Systems)
• individual designed as per customer needs
• design and manufacturing according to PED 2014/68/EC or ASME Sect. VIII Div. 1

Dashboard

The ECOTHERM electric steam system is equipped with its own logic controller to ensure constant control and monitoring of steam output performance at all times. Each boiler has a main input switch as well as fuses and power contactors for each heating element. The control panel is equipped with a modern microprocessor controller with a touch screen HMI to control and display all the equipment provided. All components in the company's control panels are electrically and wiring tested.

ECOTHERM electric clean steam generator® capacity from 250 – 10,000kg/h as standard, higher capacity on request

ECOTHERM Electric Clean Steam Generators are used in hospitals or industry when the primary available energy is electricity. The clean steam is generated by an electric resistor heating flange inside the boiler shell. The units are skid-mounted complete with feed water tank water treatment and control panel. The complete factory pre- piping and wiring ensures quick and easy installation on site. The clean steam is generated by electrical energy.

Diagram describing the working mechanism of ECOTHERM's clean electric steam generator system:

Note:

1. Clean Steam Generator: generation of clean, sterile steam by using high quality stainless steel materials. Steam generation by heat exchanger application. Consisting of stainless steel tank, removable heating bundle and all required connections for safety and control.

2. High pressure bottom blown down control: flushing of the boiler bottom where sludge is created by timer controlled blow down valve.

3. High pressure surface blown down control (TDS control) continuous measurement of water conductivity just below the water surface level. If the value is too high, valve opens until the measured value drops below the set point.

4. Pressure control: pressure will be setted mechanical (by mechanical pressure control valve) or electrical by pressure transmitter (control panel) and electrical operated valve.

5. Steam supply: clean steam outlet port from clean steam generator

6. Feed water tank: preparing feed water for steam boilers, collecting condensate, pre-heating of feed water.

7. Overflow: protection against high water

8. Steam separator unit to prevent steam regulation valves from condensate, steam will be separated by using steam separator and draining unit

9. Discharging air and oxygen vent (out of building): removing port of waste gases

10. Level control: to keep a constant water level in the tank a level control system is required. Also protection against low an high water is installed.

11 Pre-heating of feed water to protect the boiler against to high temperature differences and heat tensions, feed water needs to be pre-heated by steam injection.

12. Drain for draining of the tank

13. Boiler feed water: feed water supply connection to feed water pumps and boilers

14. Condensate return collecting the condensate from different consumers, e. g. steam pipe draining points, heat exchangers, laundry machines.

15. Blown down cooler to cool down the hot water from surface and bottom blow down outlets.

16. Water sample cooler for daily analysis of feed water and boiler water, hot water samples have to be cooled down by water sample cooler.

17. Feed water pump unit vertical multi-stage centrifugal feed water pump which feeds the steam generator with feed water. Pump is designed according to maximum steam pressure and flow capacity of steam boiler.

18. Master Control panel entire independent steam generation regulation and safety devices control

Features:

• skid-mounted, pre-assembled and wired for easy on-site installation
• operation by electrical energy
• control panel with system visualization, several interfaces with existing BMS (Building Management Systems)
• clean steam vessel and piping made of AISI 316 Ti or Duplex Stainless Steel
• design and manufacturing according to PED 2014/68/EC or ASME Sect. VIII Div. 1

ECOTHERM Turnkey Electric Steam Solution®

Optional with ECOTHERM Solar Steam System®

All components are perfectly designed and coordinated with each other. This ensures maximum efficiency and therefore maximum return of investment.

More than 1,000 installed systems in the last decades ensure the right knowhow for individually designed turnkey solutions. Steam systems are complex and individual. On the one hand a lot of different components have to be used. All these components need to be optimally coordinated with each other to ensure functionality and perfect efficiency right from day one. On the other hand steam systems operate with high pressures. Thus a failure can really be very dangerous for the staff operating the system as well as for the complete building. Therefore ECOTHERM offers complete individual turnkey solutions.

The services range from design, 3D visualization, project management, over manufacture, pre-assembly, prewiring and testing to shipping, commissioning, supervision and maintenance. Experienced ECOTHERM engineers ensure that your system operates stable, save, reaches the desired output and they train your staff how to monitor and control the most important parameters of the system.

Premium quality of the products and premium service during the whole project is the minimum you should claim for your individual steam system.
