Centrifugal Blowers for heating engineering

Compact design, low air flow, particularly high back pressure – ebm-papst centrifugal blowers for heating engineering fulfil all requirements of gas condensing Boilers, gas-fired heating systems, gasfired boilers, gas and oil burners, fuel cells and other applications. Using GreenTech EC Motors also enables higher speeds compared to the asynchronous motor, and these speeds can be controlled continuously using the built-in intelligence. You will always find the right blower in our extensive product range – whether for gas-fired units with the smallest output or large heating Boiler outputs. The optimum mix For an optimal burning process in condensing boilers, maintaining an exact mixing ratio of gas to air is critical for low NOx emissions. The high flow resistance of these condensing boilers requires blowers with steep pressure/ flow rate curves. These requirements are optimally met by ebm-papst Gas blowers with GreenTech EC motors. The blower consists of a backward curved plastic impeller that is surrounded by a die-cast aluminium scroll housing. It also has a specially shaped exhaust flange with mounting holes and pressure taps. The electronics are mounted on the motor and are also included in the delivery – for 24 VDC, line-voltage-powered 115 VAC or 230 VAC with tacho output signal or Lin/PWM input. For devices in conventional heating systems, exhaust gas blowers with attached, decoupled shaded-pole motors are used. Depending on customer requirements, Fans for 24 VDC as well as line-voltage-powered 115 VAC and 230 VAC, 50/60 Hz are available. Naturally, as part of our comprehensive expertise in system solutions, we can adapt the control system electronics to meet the individual requirements of a given application. Likewise, our centrifugal blowers are available complete with a Venturi and/or mass flow sensor. As always, this is the Concrete promise we make: The end result is not only a specific system, but a solution with a systematic improvement in efficiency.

All the facts at a glance – Ideal for high pressure in condensing boiler technology – Smallest installation space at high back pressure – In addition to AC Asynchronous motors, GreenTech EC external or Internal rotor motors can also be used, with PWM and Lin control input and tacho output for optimum combustion air flow – Easy installation of customer connections such as the exhaust flange, pressure tap, plug-and-play connector – Large product selection – for gas-fired units with the smallest output up to large heating boiler outputs – Additional advantages of the LambdaConstant System: – Fast, independent burner temperature control – Previously unattained modulation range of 1:10 compared to 1:5 for Pneumatic heating units – No gas type changeover required – Reduction of heating unit types – More efficient and environmentally friendly than conventional condensing boilers
