The R600 EVOLUTION range of  gas-fired, condensing boilers are fully modulating with ultra low NOx burners.

The range includes 7 models with outputs from 142-540kW. All models are designed to be compact, and with their wheeled bases, they are 'go anywhere' solutions for confined spaces.

Utilising the proven patented water-cooled, down-firing, premix burner system coupled with a stainless steel heat exchanger assembly, R600 EVOLUTION boilers have class-leading NOx emissions.

The R600 EVOLUTION range of boilers is packed with useful features with best-in-class performance and provide high output, efficiency, reliability and ultra low harmful emissions.

Key features

  • Robust, corrosion-resistant stainless steel heat exchanger
  • 8 bar maximum pressure - ideal for tall buildings with high static pressure
  • Incorporated flue damper - to adjust draft
  • Water-cooled side walls - no insulation required
  • Floor-standing
  • Gas-fired
  • Class-leading NOx emissions
  • 7 models with outputs from 142-540kW

Highest system flexibility

  • Boilers on wheels - ease of location
  • Narrow width - pass through standard door
  • Dismantle and reassembly available - for difficult access sites
  • Low weight - ideal for rooftop applications
  • Safety valves, pumps, low loss headers and plate heat exchangers available - providing comprehensive kit for boiler primary system
  • Room-sealed option - available with no change to standard boiler
  • Inspection glass and ignition electrodes have a flexible location - to suit site space / access conditions

Efficiency and environment

  • Seasonal efficiency as high as 110.4% - low running costs
  • 4.5:1 to 5:1 turn down ratio
  • Optional second return connection - allowing possible increase in efficiency
  • Speed controlled pump by boiler load, maintaining T - giving lowest return temperature and possible condensing efficiency
  • NOx class 6 - lowest levels of NOx emissions
  • Fully recyclable parts utilised - environmentally friendly
