ebm-papst introduces its most powerful gas blower

With its VG 450, ebm-papst has introduced its most powerful centrifugal blower yet with EC technology for premix gas boilers. Now, with only a single compact blower, manufacturers can reach heating output of up to 4 megawatts, enough to heat large buildings or housing developments with several hundred units. Such output previously called for the use of multiple cascaded condensing boilers. Now a single boiler is enough, which reduces costs for installation, operation and maintenance.

Great performance in a compact package
The blower is compact and is driven by a powerful and energy-efficient GreenTech EC motor. Its impeller and housing are made of aluminum and have been aerodynamically optimised and adapted to the characteristics of the motor, enabling speeds of up to 4,250 rpm. Thanks to its high modulation level and smooth speed control, the VG 450 is very flexible.

Easy integration with MODBUS
Among others, MODBUS serves as an interface for transmitting control signals; this open communications standard has established itself worldwide as a solution for open-loop control of actuators and sensors. This simplifies the integration of third-party components in the bus system.
