Panasonic Heating & Air Conditioning Group introduced the latest entry in the ECOi EX ™ Series, the new 460 volt unit, designed for commercial use. New to the series is the 2-way ECOi VRF Heat Recovery system, which the company says increases heating output and lowers installation costs.
STULZ Air Technology Systems, Inc. launched its next generation Mini-Space EC precision cooling system for small IT spaces. The Mini-Space EC provides up to 12kW (41 MBH) of cooling while only occupying a 2-ft by 2-ft footprint making it ideal for small IT and telco closets, high-rise buildings, laboratories, and other constrained spaces.
The new Mini-Space EC is available with CW or DX cooling in both up-flow (top discharge) and down-flow (top return) configurations with options for bottom discharge (under floor), front discharge (direct room supply), and ducted rear return (with external filter box).
