SPX Cooling Technologies, Inc. has introduced its new Marley LW Fluid Cooler, an induced-draft counterflow closed-circuit fluid cooler. The company said the new fluid cooler design incorporates patent-pending heat transfer technology, a lower height to address local code restrictions, and other significant installation and maintenance advantages.
Grundfos is extending its SL and SE range of wastewater pumps to include “medium,” “high,” and “super high” hydraulic offerings from 12 hp to 42 hp. Designed to handle raw, unscreened sewage, effluent and large volumes of surface and process water, the company claims the extended selection ensures the highest pump efficiencies over a wider range of demand and the largest free passage of solids at the lowest vibrations.
Weil-McLain® is now offering an enhanced line of its SlimFit™ high-efficiency condensing gas boilers. The company says new features include improved boiler-to-boiler communication, Modbus® and BACnet® for linking with BAS, express set up wizard, 10 preset typical heating systems, and updated controls interface for simpler navigation, at-a-glance boiler status, diagnostics, and troubleshooting.
The new Premium Efficiency vertical stacked water source heat pumps (VSHPs) from Johnson Controls offers efficiency as high as 16.6 EER and up to 18.5 EER in ground loop (geothermal) applications. The company says the design allows for simple zoning, tenant metering, and building expandability.
All Laars commercial NeoTherm boilers now come with a large color touch screen as standard equipment. The company says the screen allows quick access to the control’s full functionality.
