2 or 4 Element Configuration & Modular Boiler Configuration

Designed for maximum versatility, the Argo “AT” Series features a 2 Element boiler available
in four capacities from 6 kw to 12kw and a 4 Element boiler available in four capacities
from 12kw to 24kw. The Argo “AT” Series can also increase its’ capacity to 40kw by
“stacking” two boilers together in a Modular Boiler Configuration


Microprocessor Based Control Board

The “AT” features an advanced Microprocessor Control which safely and efficiently controls the elements. Elements energize individually, with additional elements energizing as needed depending on demand. The start-up element is rotated so run time is balanced across all elements promoting longevity. The “AT” Series utilizes a sensor connected to a probe in an immersion well to determine demand. This configuration relays water temperature back to the control board allowing the unit to efficiently maintain steady, even heat using only the elements necessary to satisfy demand. Thus the “AT” Boiler avoids the constant peaks and valleys experienced by others relying on a timer system resulting in short-cycling of the elements that wastes energy and costs the user more in electricity.


Installation, Operation and Maintenance

The Argo “AT” Series features - Diagnostic Indicator Lights, a 30 Second Pre-Purge, an Adjustable Temperature Set Point and Differential and a factory installed Circulator Relay plus on board power for an External System Circulator. Optional components such as Low Water Cut Off, Flow Switch, etc. are easily added via connections on the control board. The “AT” is available in one compact cabinet size for ease of installation. Safety features include Operating Limits with Back-Up, Redundant Relays Per Element and Audible Alarms/Fault Codes.


The Reliability

Argo “AT” Series Electric Boiler features a one piece cast iron heat exchanger and a 20 Year Heat Exchanger Warranty.
