Linea Plus is an in-wall radiator unit that features Low-H2O technology, which allows the unit to heat quickly with relatively low energy consumption. It is well suited for use in low-temperature hydronic systems and with renewable-energy sources, such as solar or geothermal. The Linea Plus' design allows for any kind of pipe or vent to be hidden behind the front panel. It has a maximum surface temperature of 109° F, even when the water temperature is 194° F. It is available as a freestanding or wall unit in 25 different colors. Jaga North America; www.jaga-usa.com Featuring an integrated LED driver,
Courtesy Autodesk CEO Carl Bass discusses the new cloud-based features for Autodesk software to industry press at a company media event in San Francisco on March 27.

The Manitowoc 16000 Crawler Crane now is available with a fixed-jib option as well as the standard luffing jib. The fixed jib has a 93-metric-ton (102-ton) capacity and a maximum length of 42.7 m (140 ft). The new jib reduces rigging time for lift applications in which a luffing jib is not required or feasible. Manitowoc Cranes; 920-684-6621; www.manitowoc.com The Atlas Copco Boomer E1 C-DH drill rig features a drilling coverage area of up to 95 sq meters, or 1,023 sq ft. This reach is a significant improvement over the company's earlier diesel-hydraulic face-drilling rig, the L1 C-DH. The rig
The York YVWA Water-Cooled Screw Chiller features a variable-speed drive that allows for more efficient energy usage. It uses HFC-124A refrigerant, which has zero ozone depletion potential and no phase-out date. The screw chiller is able to handle a higher pressure lift than a centrifugal chiller, allowing it to be used in both thermal storage and heat-pump applications. Johnson Controls; 800-537-9675; www.johnsoncontrols.com The Liebherr 65 K Fast-Erecting Crane has a lifting capacity of 1.4 metric tons at 40 meters, with a maximum lifting capacity of 4.5 metric tons. Loads are moved using a pure two-fall operation with no re-reeving. The
