Commercial Chillers for New York City & Long Island Buildings

Packaged units, usually on the roof or at grade, that reject heat with condenser fans. No cooling tower or water treatment needed — simpler to own, but generally less efficient than water-cooled plants at larger sizes.

Installed indoors and paired with a cooling tower and condenser-water pumps. Higher efficiency for large loads, with more equipment to maintain and water treatment to manage.

Scroll machines cover smaller loads with multiple staged compressors; screw chillers are common workhorses in the mid range and handle part-load well with modern controls.

Centrifugal chillers serve large plants. Oil-free magnetic-bearing designs offer strong part-load efficiency and lower maintenance, and are often compact enough for retrofits with tight access.

Multiple smaller modules that fit through standard doors and elevators, add redundancy, and allow phased replacement — often the answer when rigging a single large machine is impractical.

Capture rejected heat for domestic hot water or simultaneous heating, and are a growing electrification path for buildings facing Local Law 97 limits.
