Taco flow-through expansion tank
Taco Comfort Solutions’ new flow-through expansion tank is designed to help reduce the environmental conditions necessary for Legionella and other bacteria to flourish. With standard tank volumes ranging from 23 to 528 gallons, the flow-through expansion tank provides precise flow channeling through a patent-pending head design. Constructed, tested and certified to ASME Section VIII Div. 1, these tanks minimize pressure loss, discourage short-cycling, and are retrofittable to meet ASHRAE Standard 188 on existing designs. Standard working pressure is 125 psi with options for 150 psi and higher. They are NSF/ANSI 61-G certified and are available with a sight glass for failure detection. 401-942-8000; www.tacocomfort.com
AquaMotion outdoor circulator with freeze protection
AquaMotion’s outdoor installed recirculation pump is designed to be used with outdoor installed tankless heaters that do not have a built-in circulator. Five kits are available: two for dedicated return line, and three kits for single-pipe and On-Demand systems. The stainless union and flanged pumps can handle a total pipe length of 250 to 600 feet. The On-Demand kits include ODR by-pass valves and AMK-WB On-Demand controls. The unique design protects the pump from wind, cold, heat and water. The outdoor enclosure is sealed to the pump and is lockable. It houses the wiring, the terminals, is vented, has drains and is insect protected. The on/off temperatures are higher to compensate for the outdoor temperatures which can adversely affect the proper operation of the pump. The pump also has built-in freeze protection; if the temperature drops below 40 degrees F, it turns on the pump to protect it from freezing. 401-785-3000; aquamotionhvac.com
