Industrial Gas Boilers – Condensing – 39 kW to 1,812 kW in single boilers – up to 28,992 kW cascade- Industrial heating

Industrial gas boilers floor standing with high efficiency, fuelled by either natural gas or LPG (propane) gas available from Flexiheat UK at a great price and with high quality.

These industrial boilers / commercial boilers are the ideal boilers for any suitable commercial heating or industrial heating of buildings that require this level of heating output with high operational reliability and low emissions.

Whether you classify them as commercial boilers or industrial boilers is up to you. Officially commercial boilers, in relation to commercial boilers, the classification comes into effect at over 70kW of gas input to the boiler. From that figure on there is no real defined value for when commercial boilers are then classified as industrial boilers.

Gas condensing industrial boilers are the ideal boilers for larger buildings as a condensing boiler is the most efficient and cost-effective type of commercial or industrial boilers to use.

Industrial and commercial boilers work just like domestic boilers, just that they have a much larger output, making them suitable for industrial or commercial project requirements.

With a large heat output of up to 28,992 kW in a boiler cascade system, we have a condensing boiler range suitable for any high efficiency industrial gas boiler installations, that you can rely on to provide an efficient condensing boiler installation for your site requirements.

These units are manufactured with multiple efficient stainless steel heat exchanger modules (which are an inox radial heat exchanger) – which results in great modulation ratios to match the heating demand of the installation and a more efficient commercial boiler installation.

This also allows redundancy and ensures trouble-free operation of these high efficiency industrial boilers in the event of failure of one or more heat exchangers modules.

Industrial Boilers – Commercial Product Specifications

Our Industrial gas boilers , which are condensing and can be either natural gas or LPG ( propane ) gas fired benefit from –

• High efficiency pressure jet boiler range with efficiency up to 108.5% NCV  heat output – meaning higher than average energy savings
• Ultra low Class 6 NOx combustion emission levels  – These low emissions meeting all current business and industry environmental commercial legislation
• These industrial boilers can be fuelled by either natural gas (G20) or Propane Gas (G31)
• Maximum working pressure of 6 Bar ands a minimum of 1 Bar for this high efficiency industrial gas boiler full range
• Maximum hot water temperature – 90 degrees C
• These industrial floor standing boilers have been designed for maximum versatility and energy efficiency for commercial premises
• Homogeneous heat distribution with premix condensing technology and micro-flame metal fibre coated steel burner
• Whilst some manufacturers use a inox radial heat exchanger, we prefer an aluminium silicate alloy cast casing exchanger as it provides high operating efficiency with high heat transfer. All sub components are from leading brands on our condensing industrial gas fired boilers
• A wide option of 11 different thermal output capacity options from 39 kW- to 1,812 kW heating output range in a single unit and up to 13,440 kW heating output in a boiler cascade system / commercial boiler installations
• Provides energy saving through 1:9 modulating operation of these high efficiency industrial gas boilers
• Allows cascade connection up to 16 industrial condensing boilers in total , including 1 master and 15 slave boilers
• Heat interface units – very common for heating blocks of flats with a communal commercial boiler plant room feeding the heat interface units.
• Allows simple control with illuminated LCD panel which provides ease of use; and error codes and boiler information can be displayed on this panel
• Daily and weekly operation schedule can be programmed
• Seasonal heat program can be prepared during summer and winter times
• Full range is available as either a natural gas boiler or a propane fired industrial boilers
• Provides an advantage in boiler room planning and conversions with its compact structure in terms of area of required, due to their small foot print
• Lightweight free standing construction and supplied fully assembled on wheels
• With a maximum width of 1,250 mm , these floor mounted commercial gas boilers are extremely compact and are the ideal boilers if space is limited
• Compliant with Eco design directive – ERP approved for industrial and commercial applications
