The Avenger II Series boiler is constructed using 100% stainless steel. The superior two-pass firetube design reduces the cost of manufacturing, maintains performance, quality standards and maximizes efficiency.
The first pass of the heat exchanger consists of stainless steel rifled tubes. The spiral design increases the turbulence within the tube, which optimizes the velocity of the combustion gases, increasing the heat transfer and efficiency of the boiler.
The second pass features a stainless steel oblong tube, which has a larger diameter compared to the rifle tubing. The oval design allows us to extract the latent heat from the flue gases, creating condensate in the process.
The Avenger series utilizes a 100% stainless steel burner with a dual gas train, which due to its design, is able to maintain efficiency and low NOx. The burner is designed to combust a precise amount of premixed combustion air and gas to provide equal distribution of heat throughout the entire heat exchanger.
CONTROLS
The Avenger Series is controlled by an integrated Honeywell SOLA controller. The 7” color touch screen provides remote operation through the 4-20mA or 0-10Vdc for set point or fire rate control. Paired with the ability to control multiple pump operation along with daisy chain set up for up to 8 boilers, this user friendly control also provides you with a USB output for screenshot capture, as well as password access for service personnel. Up to 8 SOLA devices may be monitored and controlled with one single display.
In a world where we are becoming more connected, the Avenger II is ready to enter this revolutionary phase in building automation. All Avenger models are equipped with standard Modbus RTU communication protocol to allow for BMS access to view boiler operation. The remote monitoring of a boiler plant allows for complete overview of various boiler-related temperatures, boiler status, pump activation, boiler error codes and more. This is not just limited to read-only parameters, as a BMS is permitted to write setpoint temperatures, enable/disable and remotely send and receive firing rate requests. To further evolve and adapt to the changing marketplace, the Avenger II is available with BacnetIP, BacnetMSTP, MetasysN2 and LonWorks protocol support. All the features available in the Modbus RTU realm are carried into these protocol’s with the use a highly advanced yet user friendly Fieldserver Protonode. The Fieldserver Protonode is equipped with Ethernet or RS485 connectivity and is BTL (BACnet Testing Laboratory) Certified. This approval assures that we carry only the highest quality products with optimum performance and utmost ease of connectivity.
