AM Series Water Heaters

The AM Series high efficiency water heaters provide you with a powerful hot water system with a compact footprint and built-in redundancy. The AM Variable Radial Circulation heat exchanger is highly resistant to scale build-up which increases your ROI, expands the lifetime expectancy of your system and promotes uptime reliability. Multiple units can be located with near-zero side clearance for even larger installations. Internal valves are included affording you additional savings on installation costs. AM water heaters are available in six sizes from 199,000 to 1 million BTU/hr (199 and 250 available in AM Rapid Recovery Integrated only).

Each unit consists of between 2 and 4 inpidual modules, each with its own combustion chamber, burner, gas valve, and combustion controls and safeguards, all tied together to common water connections and assembled in a single enclosure. This provides the advantages of high turndown and multiple-unit redundancy, while still keeping installation costs down and operation simple. Full front access means near-zero side clearance with no loss of serviceability when more than one million BTUs are necessary. Installations take up minimal space and remain simple to service. Standard Modbus controls easily connect to Energy Management or Building Automation System.

The high efficiency of the AM series water heaters means less wasted heat and lower operating costs. In a condensing unit, lower fire rates return higher operating efficiencies. By running multiple modules at low fire rather than one large unit at higher fire, the AM series ensures the installation is always running at its most efficient. High efficiencies also mean lower flue temperatures and thus a range of venting options. All units can be vented in polypropylene, PVC, cPVC, or AL-294C vent materials.

AERCO Digital Mixing Station (ADMS)
Lead-free, ASSE 107 certified ADMS is a smart water tempering system that allows temperature controlled distribution of potable hot water throughout the loop. The building automation system (BAS) ready ADMS™ can be configured with strainers, building recirculation pump and Flow/BTU monitor package to allow facilities managers to remotely monitor and control distribution water temperatures along with monitoring of flow and energy consumption.

Communications Gateway
Optional accessory supports heater communication with your facilities BACnet, LonWorks and N2 systems.

Domestic Water Storage Tank
AERCO storage tanks are ASME certified glass-lined or stainless steel pressure vessels designed for use with water heaters. When contending with challenging applications they assure consistent hot water service during peak demands. The AERCO storage tanks are available in stratified or accumulator storage configurations.

Cascade Sequencer
AM Series Sequencer will maximize the performance of a bank of AM Boilers or AM Water Heaters with single storage tank. The two sequencer options include:

  • Cascade Manager – Budget friendly sequencer with ability to control up to 8 units dedicated to either space heating or domestic water heating with single storage tank
  • AERCO 284 – Advanced sequencer with ability to perform domestic hot water priority, equal run-time rotation, pump exercising and BACNet communication

Contractor Kit
Includes all the spare parts necessary to service and maintain the unit, including control board, igniters, flame rods, and all the screws, nuts and gaskets.

Hydroskrub
A liquid descaler specifically designed to dissolve all water scale, lime, mud, rust, and other water-formed deposits from water operated equipment and systems.
