Dirty cooling towers cause damage to cooling systems and can be breeding grounds for dangerous bacteria. The Goodway CTV-1501 cooling tower vacuum helps keep cooling-tower basins clean without draining your tower, saving time, money, and water. With the optional F2 filter, it can return crystal-clear water back to your cooling tower. The CTV-1501 is simple to use and quickly vacuums mud, dirt, and other debris from basins and cooling-tower walls, leaving cooling towers spotless. —Goodway Technologies
Greenheck’s new Vektor-MS inline mixed-flow laboratory exhaust fan reduces fan energy in demand-based laboratory-exhaust applications and safely allows variable-frequency drives to be applied to laboratory exhaust fans. Featuring noninvasive flow monitoring, the fan’s operation adjusts throughout the day based on demand. The variable-geometry discharge nozzle maintains constant discharge velocity at the fan exit. Available in belt- or direct-drive configurations, the fan utilizes mixed-flow impeller technology and a bifurcated fan-housing design for access to drive components. Its vacuum shaft seal ensures fumes do not escape through the shaft opening. Performance capacities range from 1,500 to 38,000 cfm and up to 8 in. wg. —Greenheck

The Circulatic is a forced-recirculation watertube boiler that uses a drum as a steam separator and a reservoir of water to supply coils. A recirculating pump draws the water from the drum and forces it through a set of parallel-connected coils at the rate of three to four times the maximum steaming rate. The high-pressure boiler achieves full steam in five minutes with steam from 2,580 to 20,700 pph and pressure from 15 to 530 psi. Completely packaged and fully tested, it is compact in size and weight, has fully modulating output and is safe to operate. —Vapor Power
