Reznor RHeco Low NOx High Efficiency Condensing Unit Heater 25.0kW - 93.8kW

Reznor RHeco Low NOx High Efficiency Condensing Unit Heaters

Thermal Efficient, Emission Reducing Heating System

The RHeco range offers a carbon friendly, emission reducing, energy saving and thermal efficient heater system. This system operates with ultra-efficient gas fired unit heaters that are ideal for buildings and organisations looking to reduce their emission generation and lower their carbon footprint.

The unit surpasses current Building Regulations L2 requirements. Offering substantially reduced CO2 and NOx emissions (under 25 ppm) which is consider[1]ably lower than the emissions of the previous generation of unit. With a thermal efficiency up to 109% providing exceptional levels of seasonal efficiency. This both reduces carbon levels and energy usage at the same time leading to a cheaper and more environmentally friendly operation.

Between the high flow axial fan and the 5:1 turn down ratio, this unit offers a versatile variety of features designed to ensure temperatures can be accurately maintained at minimal heating loss. These features maintain a steady dispersal of rising hot air creating a decreases stratification effect.

The built in Smartcom technology provides a diverse array of operational options. The system allows for up to 16 separate units to be centrally controlled through a master unit. This simple to operate system also provides a cost-effective means of management and operation as each unit can be operated independently through the master unit.

This heating system is perfect for use in a variety of applications from Automotive workshops, Factories, Retail outlets, Sports facilities, halls, Warehouses and Workshops.

The condensing units come in five models available with heat outputs ranging from 25.0kW, 32.7kW, 49.4kW, 69.2kW, 93.8kW and operate on both natural gas or propane. Maintenance is seamless with all controls accessible through a single side and are housed behind a hinged door

This heating system was designed with safety & reliability in mind. A microprocessor burner control provides full safety monitoring and multi-try ignition control. Multiple failsafe are also built in to shut down the machine in the event of overheating, inadequate combustion air, blocked flue or flue fan failure. No gas or flue gas can escape into the heated spaces thanks to the new “pull through” combustion technology.

Thermal Efficiency: The units exceed the requirements of current Building Regulations L2, with thermal efficiencies up to 109% to provide exceptional levels of seasonal efficiency.

Substantially Reduced Emissions: The RHeco range provides the highest efficiency levels and substantially reduced CO2 & NOx emissions (under 25ppm). This is ideal for Ideal for low carbon buildings.

Reduced Energy Bills: When replacing traditional units more than 10 years old, savings of 30% can be achieved. Up to 35% energy saving on replacement heaters.

Versatile Flue Options: Operates on both natural gas and propane.

High flow Axial Fan: Decreases stratification and improves heat distribution.

Temperature Control: 5:1 turn down ratio for close temperature control. Reduced temperature gradients help prevent stratification.

Optional Modulating Supply Air Fan: (100 to 50%) Full speed when full burner rate, 50% fan speed when burner at 20%. Fan modulates between these two points.

Efficient: “Pull through” technology ensures no gas can escape into the heated space. Powerful air throw means improved heat distribution.

Diverse Operational Options: To complement the high efficiency RHeco units a versatile range of SmartCom control panels are available. Allows up to 16 units to be centrally controlled. Functions controlled by the master unit include.
