The Brain® Digital Recirculating Valves

Engineered exclusively for continuously recirculated hot water systems, The Brain® improves performance and safety by delivering hot water at a consistent, pre-set temperature to the points of use. Armstrong’s groundbreaking digital technology resists temperature creep during periods of zero system demand, eliminating the requirement for manual throttling valves, supplementary RTD or a temperature actuated switch to control the pump.

Available in a range of sizes to accommodate your hot water system dynamics.

  • Resists temperature creep during periods of zero demand
  • +/- 2°F / 1°C control
  • 1°F / 1°C minimum system temperature loss
  • Over temperature and power failure shutoff; emergency mode
  • Component self-diagnostics
  • Programmable temperature alerts, set point, and thermal disinfection
  • Supports implementation of energy-efficient, low temperature loss systems
  • Integral BACnet connectivity

Ascend® High-Efficiency, On-Demand, Gas-Fired Water Heater With The Brain® on Board

With The Brain® on board, Ascend® provides the world’s first fully integrated, single footprint, tankless hot water generation and water temperature control solution compliant with ASSE 1017.

  • Precise +/- 2°F hot water system temperature control
  • Ensures water temperature is raised above the threshold for Legionella survival
  • Tankless system reduces Legionella incubation risk
  • Delivers operating efficiencies as high as 99.8%
  • High-efficiency design delivers more hot water while consuming less fossil fuel
  • Digital intuitive user interface

Armstrong Heat Pump Packages

Built for your specific project and application, Armstrong water source heat pumps redeploy the waste heat from your central HVAC system and other sources to generate hot water—without burning fossil fuel onsite. While gas-fired equipment remains a preferred water heating solution for some projects, others can benefit from a hybrid solution that leverages both gas and heat pump energy.

Armstrong heat pumps are a packaged solution that offer significant advantages, including:

  • Reduced CO2 emissions
  • Lower energy consumption
  • High COP
  • Reduced reliance on fossil fuel

Rada™ Hands-Free Digital Faucets

Hands-free digital controls reduce opportunities for cross contamination while pre-set temperature and flow reduce water and energy usage and protect users from scalding. Rada™ Digital Faucets also offer a programmable duty flush option to evacuate idle water from the system, which can significantly inhibit the incubation and spread of Legionella and other waterborne pathogens.

  • The Brain® digital performance, microsized in a point-of-use fixture
  • Collection of key statistical data on usage patterns supports compliance with ASHRAE Guideline 12-2000 and ANSI/ASHRAE Standard 188-2018
  • Innovative bacterial-resistant internal design
  • Sensible thermal disinfection protocol—one fixture at a time
  • Programmable automatic fixture flush to evacuate stagnant water
  • ASSE 1070 approved—no requirement for separate under-sink TMV
  • Programmable hands-free activation and temperature control
  • Bluetooth® technology for programming and information management

Standards of Care

A Standard of Care is defined as acknowledged applicable laws, standards, and guidelines.

The OSHA Technical Manual, NAESM Management of Legionella in Buildings, ASHRAE 188, ASHRAE 12, ASPE Engineering Methodologies to Reduce the Risk of Legionella in Premise Plumbing Systems and VA Directive 1061 are all Standards of Care which include critical recommendations for establishing and monitoring hot water system temperature control limits.

There are also recommendations within these Standards of Care for thermal disinfection and fixture flushing to evacuate idle water protocols which Armstrong can help you address.

Reducing the Risk

Following a Standard of Care can minimize the risk of scald injury, Legionella-related illness and the associated litigation.

“Compliance with the new ASHRAE standard likely will be viewed by courts as the standard of care in personal injury lawsuits involving exposure to Legionella. Adopting industry standard practices and complying with applicable law is the best defense. Conversely failure to follow such standards and legal requirements could expose building owners and operators to potentially significant liability.” (Law.com July 2016)

“Former guests of the Las Vegas Aria Resort & Casino can’t seek punitive damages in a case alleging they contracted Legionnaires’ disease from the hotel’s water system, because management took adequate water safety steps, a Nevada federal judge ruled Monday.” (Law 360 Legal News Service, 2015)

 

ASHRAE Guideline 12-2000

4.1.6 Recommended Treatment. Hot water stored above 140°F (60°C), minimum recirculated return 124°F (51°C).

 

ASHRAE Standard 188-2015 Legionellosis: Risk Management for Building Water Systems

6.1.3 Control Limits. Establish limits within which a chemical or physical parameter must be monitored and maintained.

6.1.4 Monitoring. Establish a system for monitoring the parameters associated with the control limits established in 6.1.3.

6.1.7 Documentation and Recordkeeping. Establish documentation and maintain records.
