Product Spotlight
Mueller Steam is helping facility engineers detect when strainer maintenance is needed to prevent production downtime. New differential pressure monitoring technology now comes standard on our duplex strainers and is optional on our wye strainers.
With the purchase and activation of an add-on connection kit, the pre-installed pressure sensors at the inlet and outlet of the strainer monitor the pressure drop that occurs over time when a strainer screen becomes clogged by foreign particles.
Alerts are triggered via an existing BMS connection or cellular gateway when the strainer basket is 75% full and 100% full.
These sensors do not change the operation of the strainer – they still comply with all the necessary certifications and do not interfere with the normal function of the strainer.
“This is the first smart strainer technology of its kind,” says Jennifer Carlino, Sr. Product Manager at Mueller Steam Specialty. “Facility engineers will now be able to perform strainer maintenance proactively, rather than reactively, which will help protect costly equipment from damage as well as maintain consistent flow and efficient system performance.”

Stone Mountain Technologies, Inc., an innovative manufacturer of thermally-driven heat pump systems, announces North American market availability of its Anesi branded heating products for residential and commercial customers in February 2024.
Anesi gas heat pumps are air-to-water heat pumps and use natural gas, propane, or renewable gas as the primary fuel source. They use up to 50% less fuel and work at efficiencies well above 100% even in below zero temperatures.
Unlike traditional furnaces and boilers, the Anesi gas heat pump and all refrigerants, combustion processes, and venting are located outside. Only a warm water / food-grade glycol mixture enters the home through standard PEX or copper piping. Our natural refrigerant is environmentally friendly, will not harm the ozone layer, and will not break down into harmful, lifetime chemicals like PFAS.
Homes and businesses that use gas or propane for heating now have a solution that reduces their emissions at a lower cost and without sacrificing comfort and reliability, even at very low outside temperatures.
“An Anesi gas heat pump will reduce the energy used for space heating and water heating by 30 to 50%, so you will see a significant difference in your heating bill and a corresponding reduction in your CO2 footprint,” said Stone Mountain Technologies, Inc. CEO Michael Garrabrant. “We have a whole family of Anesi products under development; we’re just getting started and see limitless possibilities for this technology.”
