First technology to allow monitoring of every return circuit in a radiant system

Viega LLC’s new Radiant Auto-Balancing System (RABS) delivers an unprecedented level of control and consistency in radiant heating systems.

RABS gives users for the first time the ability to independently control each zone in a radiant heating system. Balancing valves are not required and installers can commission as many as eight thermostats and 12 circuits per control unit. RABS achieves the desired temperature in each zone by analyzing the supply water temperature, each circuit’s return temperature and zone air temperatures where a wireless thermostat is used. The system offers four operation methods that complement each other.

“Achieving and maintaining consistent temperatures through multiple zones has been a challenge for radiant heating systems. RABS automates and digitizes the process, which helps installers and users alike,” said Adam Botts, Portfolio Manager.

RABS compensates for system inconsistencies and imperfections like:

  • Different circuit lengths or tube sizes
  • Varying installation clearances or tube depths/spacing
  • Change of floor coverings
  • Fluctuating supply temperatures, outdoor temperatures or external heat sources

In addition, a web-based app-enabled control lets users to manage the system from anywhere in the world. It allows remote control of power levels, thermostats and operation software. A local device can access the web app or it can be accessed remotely via the internet.

RLS LLC, manufacturer of the Rapid Locking System line of flame-free press-to-connect fittings for HVAC and refrigeration systems, announces that Milwaukee® Tool, in partnership with RLS, has introduced RLS-compatible jaws for use with its popular M18™ FORCE LOGIC™ Press Tools.

Available in sizes from 1/4″ – 1-3/8″, these new RLS ACR Press Jaws will allow M18 tool users to take advantage of the time-saving and safety benefits of flame-free RLS press connections for HVAC/R, without needing to invest in a new press tool. These are the industry’s first jaws approved to press RLS fittings using 32 kN (kilonewton) tools.

In addition, the new Milwaukee jaws are also compatible with a wide range of other 32 kN tools on the market, including those from manufacturers such as RIDGID, Klauke, Viega, Dewalt, NovoPress and Rothenberger. Contractors who already own any of these tools will only need to purchase the Milwaukee jaws to begin installing RLS fittings.

Milwaukee’s RLS-compatible jaws will be sold exclusively through Milwaukee distributors. Contact Milwaukee or visit milwaukeetool.com for details. For more information on RLS press fittings, and a complete RLS Tool & Jaw Compatibility Matrix, visit rapidlockingsystem.com.

About RLS Fittings

RLS press fittings connect in 10 seconds using a battery-powered tool and jaws, replacing the time-consuming process of manually brazing HVAC/R joints. The fittings result in faster, more consistent connections that reduce total installed costs, while also increasing jobsite safety by eliminating the use of an open flame. More than 10 million RLS fittings have been successfully installed since their introduction in 2015

New S20W 20-gallon tanks have industry-best recovery rates and high efficiency

NTI Boilers, Inc. introduces the S20W high-performance wall-mounted indirect water heater. With ultra-high performance and unprecedented space-saving installation flexibility, the S20W offers heating contractors multiple benefits for a variety of new installations as well as for retrofit projects.

Featuring an industrial size stainless-steel coil and with its capability of 445 GPH first-hour recovery rate, the 20-gallon S20W exceeds most industry standard 50- and 65-gallon indirect tanks. Efficiency is further improved by a CFC-free 2” ultra high-density EPS insulation that reduces standby losses. The S20W is characterized by high-quality 444 stainless-steel material for the coil and the tank, completely pickled and passivated inside and outside to remove all surface contaminants and restore the chromium oxide layer.

Each tank comes with a low lead thermostatic mixing valve that is ASSE 1017, ASSE 1070, cUPC, and CSA125.3 approved, a 10k NTC tank sensor with embedded UL353 limit switch for the insertion into the stainless steel well, and a 150 psi Temperature and Pressure (T&P) relief valve.

Flexible Installation Options

The S20W provides contractors with design flexibility. An extremely small footprint makes the tank ideal for limited-space installations. The S20W is compatible with all hydronic boilers on the market or existing installations. Inspection and cleaning are easy through a hand hole at the top of the tank. An optional floor stand is available for applications where the tank needs to be floor mounted.
