Unipower VA Series
The Unipower VA Series burner is one of the easiest high turn down burners to set up in the industry. The air-fuel modulation is achieved through the relationship of the supplied air pressure and the output pressure. The combustion air motor is a variable speed blower which creates a pressure relative to the air output. Output gas pressure can be varied relative to the air pressure through a ratio regulator eliminating the need for linkages.
The Unipower VA Series can operate as low as 7% excess air (1.5% O2 at flue) at high fire with low CO emissions. This translates to energy savings and a lower carbon foot print. In comparison, a conventional commercial power burner requires 25% excess air for it to operate safely. For the Unipower VA Series burner, there is no need to heat up the excess air that is not consumed in the combustion process, thereby reducing overall fuel consumption and lowering operating costs. The Unipower VA Series burner’s air modulation allows it to operate at lower excess air at all firing rates with low CO emission compared to other burners that do not modulate the air. The CO emission is well below US and European industry standards.
The combustion blower is the component that consumes the most electric power. The Unipower VA Series burners use a smaller variable speed blower compared to most commercial power burners with the same firing capacity. Since this burner uses a variable speed blower, it does not always run at the highest speed nor does it require the full use hp of the blower. The speed of the motor is relative to the heating requirement. The Unipower VA Series burner housing and the control box are all made from stainless steel. It has better durability compared to most other power burners that use painted cold rolled steel, especially when used in a harsh environment.
Most of the noise of a power burner is from the blower. Even at high fire, the Unipower VA Series burner creates less decibels because the cast aluminum blower is designed to reduce noise levels with efficient output as compared to a conventional sheet metal blower housing. The burner is engineered with the customer and service personnel in mind. The burner will be completely assembled and fire-tested in our factory so that the user will require very minimal effort to set up the burner upon receipt.
Its modular design gives it a wide input range: 6″ (V1) 670,000 BTUs to 36″ (V10) 3,800,000 BTUs
Remote mounted control boxes available
Flame rod, UV scanner, and Infrared sensing options available
Easy fuel air adjustment, set up, and serviceability
Increased combustion efficiency and lower electric costs
Note: Burners with Fasco blowers are only recognized and need to be installed within a vestibule
OEM versions of the Unipower VA Series burner are available
