Ultra Low NO_XStokvis Boilers

Econoflame R6000 is the condensing ultra low NO_xpremix commercial boiler from Stokvis Energy Systems.

Econoflame R6000 is the condensing ultra low NO_xpremix commercial boiler from Stokvis Energy Systems.

The R6000 range includes seven models with outputs from 142 to 539 kW.  Utilising the proven patented water-cooled, down-firing, premix burner system coupled with all stainless steel heat exchanger assembly, R6000 boilers have a class leading NO_xemission of between 15 and 35 mg/kWh with 0% 0₂and can return seasonal efficiencies up to 110.4%.

For easy installation the boilers are designed to pass through doors with widths from 670mm to 770mm, the floor space requirement being within the range 0.74m²to 1.34m². Each model is equipped with two return connections as standard allowing high efficiency to be achieved when serving a mix of high and low system circuit temperatures. Another feature is the option to use the boiler in either standard flue or room sealed applications without modification.

The R6000 is suitable for use in single boiler or multiple/cascade installations. Optional extra low loss headers are available and if being used in a retrofit application onto old systems, plate heat exchangers are available for total boiler isolation. The modulating burner system allows turndown ranging from 5:1 to 7:1 to return optimum efficiency at low system loads.

A long operational life is ensured through the use of corrosion resistant stainless steel as heat exchanger material, water cooling used in place of insulation and no degradable insulation materials are used. Hydraulic and safety related options available include plate heat exchangers for system separation, low velocity headers for hydraulic and pump and pressure relief valve kits.  Easy servicing is helped by an inspection hatch fitted in the heat exchanger, which can be used for wash down purposes - no insulation is present.

The R6000 is equipped with a boiler management unit. Besides controlling the boiler and all safety devices connected to the boiler, this unit also takes care of the temperature control of the boiler via an integrated PID controller.

For additional control features, the boiler can be equipped with a heating zone controller.
