AERCO
Sequoia is a high voltage immersed electrode hot water boiler designed for large commercial and industrial applications, including hospitals, universities, and manufacturing plants. Virtually 100% efficient and emission free, Sequoia provides an ideal solution for applications where building decarbonization or electrification are key considerations.
Sequoia features long-life, low-maintenance electrodes and has fewer parts to clean and maintain compared with electric element boilers. There are no combustion hazards because there are no flames, fumes, fuel lines or fuel storage tanks.
The boiler is simple to install and even simpler to operate and maintain. The automatic controls provide seamless control over an output range from 10% to 100% (10:1 modulation) to optimize for demand fluctuations. Available in eight sizes from 2,500 kW to 68,000 kW (~8,550 MBH to 232,000 MBH) with power voltage from 4.16 kV to 25 kV.
Meet Electrification and Decarbonization Goals
Quiet, clean, and emission-free with virtually 100% energy efficiency. The Sequoia boiler checks all the boxes for an effective, eco-friendly solution, ideal for building decarbonization or electrification projects. Additionally, challenges that are associated with other energy sources, such as noise, fuel fumes, fly ash and large stacks, are simply non-existent with a Sequoia boiler in place.
Lower Operating Costs
The Sequoia boiler is simple to operate with its automatic controls (PLC), reducing the need for operating and supervisory personnel. Since the boiler heating loop is isolated from the existing heating water system, costs associated with water treatment are practically eliminated. Furthermore, taking advantage of lower energy rates during daily or seasonal off-peak periods can cut the energy bill significantly.
Simplify Installation
Sequoia can match the capacity of large gas or oil-fired boilers (up to 68 MW) while occupying a much smaller footprint. Operating at distribution voltages, electrode boilers eliminate the need for fuel lines, storage and handling equipment, economizers, isolating piping connections, and emission control equipment for significant savings on capital expenditures as well as space in the mechanical room.
Ensure Safer Operation
There are no combustion hazards with Sequoia as there are no flames, fumes, fuel lines or fuel storage tanks. Nor is there any low water danger since the current cannot flow without water and there are no problems with heat buildup or electrode burnout even if scaling should occur. The unique design of Sequoia improves safety further due to the fact that a grounded pressure vessel and a safety enclosure around the boiler are not required while in operation.
Minimize Maintenance and Improve Reliability
Sequoia is built with long-life, low-maintenance electrodes and has a minimum number of components and electrical controls compared with electric element boilers. The result is fewer parts to clean and maintain and greater reliability.
AERCO provides reliable, cost-effective heating and hot water solutions to a wide range of commercial markets. Using a system-design approach, their easy-to-install, compact condensing boilers and water heaters deliver superior building performance at lower operating costs – providing peace of mind and the lowest cost of ownership.
