Marketair Brasotek for HVAC/R Copper Pipe/Fitting Brazing PreparationMarketair Inc., an Edison, N.J.-based supplier of specialized and innovative  installation components for the North American HVAC market, introduces Brasotek, a cutting-edge, time-saving method for prepping copper pipe and fittings prior to brazing.

Brasotek replaces traditional methods and reduces the time needed to clean the joint areas on brazed copper linesets by more than 50 percent. It conserves filler rod, reduces the need for flux, requires lower brazing temperatures and less brazing time by 15 percent.  The eco-friendly, non-toxic and biodegradable liquid, which is non- flammable, is intended primarily for linesets as used in most ducted or ductless VRF/VRV AC systems, but can also be applied to most plumbing, hydronic heating or any installations requiring copper pipe and fitting brazing.

Brasotek is available in two configurations: The BTA-5 Mini is a small felt-tipped, pen sized applicator with a 6-ounce (5-ml) bottle for smaller pipes, and the BTA-20 MIDI is a larger version with  6.7-ounce (20-ml) bottle and 1-inch-long applicator pad for larger pipes. Both versions eliminate the cleaning of joint areas with emery cloth, which is difficult to use correctly on interior surfaces, very time-consuming, susceptible to deep scratching surfaces and creates copper dust and filing residue, which often migrate into the interior of the lineset and create a potential to clog valve orifices.

Currently the only known liquid brazing preparation of its type for copper pipes and fittings, the patented Brasotek solution is simply brushed on to the surfaces surrounding the weld area and evaporates within 5 to 10 seconds. This provides a bright clean surface that remains usable for up to 90 minutes. The result is  perfectly brazed connection when using a silver/phosphorus filler rod commonly-used in high pressure refrigerant applications.

Other Brasotek features include:

  • Replacement bottles of cleaning solution are available separately.
  • Applicators tips or pads can be reused many times and are also available as replacements.
  • For very large pipe sizes, larger applicators are available on request;
  • Cleaning with Brasotek is very cost effective, due to the minimal fluid usage and is considerably cheaper than the cost of a callback due to a braze connection that leaks due to poor cleaning.
  • Packaged in a clear clamshell J-hook merchandiser with a four color label and instruction sheet;

Well-established in its home country of Italy, as well as other parts of Europe,  Brasotek is the preferred in-factory brazing choice of a number of local air conditioning manufacturers such as ONDA, OLIVET, SAMBONET, NOVATERM and other European HVAC/R manufacturers. The Brasotek process is available on video at www.marketair.com/brasotek.

Viega LLC’s new Automatic Recirculation Balancing Valve ensures a balanced domestic water recirculation system by dynamically changing with varying conditions.

The Automatic Recirculation Balancing Valve is a modification of a Viega product that has been used successfully in Europe for years. It helps keep water temperatures more uniform by adjusting flow with changes in temperature. The results are faster hot water delivery, minimized waste energy and water and less stagnation and chance of contamination. Among the valve’s features:

  • Unlike with manual valves, temperature can be set once and be maintained automatically.
  • Settings can be changed easily, if needed.
  • Can be installed on risers or branches
  • Remote monitoring with temperature sensor
  • Optional thermometer provides visual indication of valve setting
  • Threaded ends allow it to be used with Viega ProPress or Viega PureFlow fittings systems
  • Includes bypass for thermal disinfection

Additional accessories that can be used with the valve include a thermometer, drain valve and optional insulation sleeve.

“Viega is committed to providing hot water quickly and efficiently while improving water quality and the new Automatic Recirculation Balancing Valve is a significant step toward that goal,” said Paige Riddle, product manager, valves. “This valve offers more features than any other on the market while requiring minimum work on the part of designers, engineers, installers and building maintenance personnel.”

A. O. Smith (www.hotwater.com) has announced the launch of  the Cyclone® LV, a large volume commercial water heater which rounds out the company’s industry-leading Cyclone family of high-efficiency gas products.

A. O. Smith created the LV model to serve the needs of facilities that require large storage for jobs with critical load requirements. The Cyclone LV model’s modulating process adjusts the burner’s firing rate to a specific demand, which allows for a highly efficient performance of up to 96% thermal efficiency while dramatically lowering operating costs. Available in 220- and 250-gallon capacities, these units allow engineers to specify two Cyclone LV units where they would have previously needed four Cyclone Mxi® units.

“The Cyclone family revolutionized the market in 1996 and provided innovation that we continue to build on today,” said Matt Schulz, senior product manager for commercial new products at A. O. Smith. “Cyclone LV models combine popular BTU inputs with new larger storage capacity. With the larger storage capacity a single LV unit can be used in place of multiple standard tanks freeing up space.”

Cyclone LV products feature advanced electronic control with built-in diagnostics and free iCOMM™ remote monitoring. LV models are designed for maneuverability and ease of installation due to their lightweight design.
