Robustness – stainless steel heat exchangers for tough conditions

Flue gas side

ELCO utilises high grade stainless steel on its heat exchangers to resist corrosion from fl ue gas condensate – enhancing a boiler's durability and longevity.

Water side

The water quality in a system is of high importance when optimising effi ciency and long term performance of heating equipment. One of the key factors to consider is the pH value.

The potential problems

If water quality is not maintained at the correct pH level (7 to 8.5), there is a high risk of the pipework corroding, or scale forming on the internal surface.

The pH of water

Soft water has a low pH value and can cause corrosion within the system due to the presence of hydrogen molecules. In hard water areas, scaling can form on the inside of the system pipework.

The combustion of gas and air

Due to impurities in gas and air, the combustion process produces acids. However, at high temperatures, there is limited impact from corrosion due to the lack of water present.

Stainless steel heat exchanger

Stainless steel is the preferred material for heat exchangers as it is far more resistant to corrosion than other metals.

Water quality

The quality of water within a heating system is rarely stable, with pH values likely to increase over time and also cause corrosion.

Condensing boiler effi ciency

Below the point of condensation (57.2ºC at 10% excess air) where condensate is present, dissolved sulphuric and nitric acids can corrode the heat exchanger material.

Stainless steel for high effi ciency

A unique robotised laser welding process

ELCO utilises the latest laser welding technology to ensure its stainless steel heat exchangers provide best in class effi ciencies,excellent reliability and unbeatable performance over their lifetime.

Overall heat transfer vs. exposure time

Stainless steel vs. other metals

Although a stainless steel heat exchanger starts its life cycle with a lower heat transfer rate, the material is far more effi cient over its entire lifetime – performing better for longer.

Effect of chromium content on scaling resistance (at 1,800ºF or 963ºC)

Stainless steel consists of iron and at least 11% chromium. If enough chromium is added, a protective passive fi lm will form to protect the metal from corrosion.

Aluminium

Other metals, such as aluminium, also produce a protective oxide layer. However, in the presence of moisture and high temperatures a porous oxide/hydroxide layer can form – reducing scale resistance and increasing risk of corrosion.

Stainless steel

A passive fi lm of chromium oxide (10nm thick) prevents any corrosive attack, ensuring surfaces remain smooth and bright. This eliminates the accumulation of fouling and deposits.

Crevice-free weld

A thin weld seam between the fi n edge and tube allows extremely fast heat transfer, while providing long term material stability.

Deformed material

Due to the material deforming from standard welding, heat up times are far slower, reducing overall effi ciency and product longevity.

Effi ciency and emissions – experts in combustion technology

Water cooled heat exchanger

By cleverly channelling water through the heat exchanger walls, the combustion chamber is effectively cooled without the need for insulation.

Furthermore, this process allows additional energy to be recovered and transferred to the heating water – increasing boiler effi ciency and reducing radiation losses.

Low emissions

A water-cooled cold fl ame burner, combined with an optimised combustion zone, achieve extremely low NOx and CO emissions, which already comply with future NOx class 6 requirements.

Heat exchanger geometry

ELCO's state-of-the-art heat exchangers have a unique geometry, providing reliable and robust performance. They are all specifi cally designed for optimised effi ciency and functionality during their entire lifetime.

Optimised heat transfer

The cooling tube expands into the heat exchanger wall and provides an enhanced surface contact, which maximises heat transfer.

Hydroforming process

To maximise heat extraction throughout the cooling tubes, hydroforming technology isused during manufacturing.

This specialised process, which is popular in the automotive industry, consists of the cooling tubes being fi xed in place under the infl uence of a highly pressurised fl uid. This increases the diameter of the tube and forms a perfect seal.

Modular construction – the smart concept

Boiler construction

ELCO boilers are specially designed for quick and easy disassembly into component parts, allowing easy access to boiler plant rooms in every application.

Application benefi ts

With a compact, modular design, ELCO boilers can be used in a wide variety of projects and easily transported through a building's infrastructure.

Lightweight materials

By utilising the latest lightweight materials, ELCO boilers can be transported easily, without the need for lifting equipment or extra people.

Easy access

Thanks to their compact dimensions, many ELCO boilers can be transported using a standard elevator, rather than freight or service elevators.

Compact design

ELCO boilers are practically designed, so they can be transported through standard sized doors with ease.

Rooftop plant room

Lightweight materials allow multiple boilers to be situated on rooftops, without concern about reinforcing the fl oor.

Tight access

The boilers can be disassembled into smaller, manageable parts, allowing them to be transported via existing access routes, such as stairwells.

Sectional heat exchanger

A sectional heat exchanger design allows a boiler to be disassembled into smaller pieces for easy manoeuvring.

Installation costs

When all aspects of an installation – such as transport, connections, pumps and low loss headers – are considered, a low water content unit offers substantial savings on installation time.

Energy consumption

With considerable differences in gas consumption and start up/stand still losses, low water content boilers deliver huge lifetime savings.

Calculation is based on a reference project with 800kW power.

Fast and furious

ELCO's state-of-the-art low water content boilers are capable of adapting to the changing demands of every application. A low water volume allows the units to respond rapidly to the changing temperature demand from the system and provide a perfect hydraulic balance – even in more complex installations when combined with other heat sources.

Light and robust

The low water content design allows ELCO heat exchangers to be mechanically decoupled, using fl exible seals and gaskets.

Compared to units which have one completely cast or welded sections, ELCO boilers are specifi cally designed to handle thermal stress when heating up and cooling down, even at higher temperature differentials.

VARION® C-POWER – One range for all commercial applications

Flexible system and modulation controlVARION® C-POWER can operate in parallel with grid connection, while Model L can also operate as a standalone unit without connection to the grid. Plus, intelligent control systems facilitate modulation of actual power or heat output requirements.

System integrationVARION® C-POWER is suitable for cascade CHP installations of up to three units. In addition, all models can integrate seamlessly with other ELCO products to offer an optimised system that is customised to every application.

Remote accessAll VARION® C-POWER units are equipped with a modem for remote monitoring, management and analysis of the unit via a smartphone or tablet. As standard, a 24-month mobile data allowance is supplied, which can be extended on request (with full service included). Data is stored on a secure server via live tracking for evaluation and support.

Superb effi ciencies An integrated condensing unit offers overall net effi ciencies up to 109.5% for models with a power range of 5.0 - 30.0kWel. Condensing CHP units are also available for 50kWel models on request.

Ultra-quiet operation An incredibly low engine speed, combined with an acoustic reduction system, signifi cantly lower noise emissions – allowing VARION® C-POWER units to be installed in a variety of locations without the need for additional soundproofi ng.

Less fl oor space VARION® C-POWER has a compact design and can fi t through standard doors for simple installation. All models can also be disassembled and rebuilt on-site in a required location upon request.

Smart controlAn integral touchscreen colour display provides easy adjustment of settings, while temperatures, runtimes, operation conditions, as well as the power and heat generation are displayed in detailed graphics and tables.

Highest environmental standardsVARION® C-POWER units are certifi ed to the highest A++ effi ciency class for outputs from 5.0 – 30.0kWel – maximising energy savings and reducing CO2 emissions.
