Advantage Outdoor Air-Cooled Central Chillers

Overview

A weatherproof Advantage plant chiller that sits on a pad outside the building - no mechanical room, no tower.

Advantage outdoor air-cooled central chillers arrive fully charged, tested and ready to run: set the unit on a pad, connect power and the process water piping, and fill the loop. There's no cooling tower to maintain and no mechanical-room space to find - the whole plant chiller lives outside on its own footprint.

Units are available as single-zone packages, delivering one chilled-fluid temperature to the whole plant, or dual-zone packages that produce two independent fluid temperatures from one chiller frame - useful where part of the plant needs a colder process fluid than the rest, without running two separate chillers.

Capacity runs roughly 5 tons in the smallest single-zone models up to the low 200-ton range in the largest dual-zone units at typical 50°F leaving-fluid conditions. Colder leaving temperatures reduce the effective tonnage of any given frame, so confirm your required temperature before comparing models by tonnage alone.

See the OACS series for the full line of Advantage outdoor air-cooled packages on this page, 5 to 210 tons, single- or dual-zone, with complete part numbers and specs.

Weatherproof by Design

An Advantage outdoor air-cooled chiller is built for its environment from the frame up: powder-coated or galvanized cabinetry, weather-protected electrical enclosures, and controls rated for the ambient extremes of the install site. In climates with hard winters, low-ambient controls keep the condenser fans and refrigerant circuit operating correctly at cold outdoor temperatures rather than shutting the unit down or damaging components; in hot climates, the condenser is sized against the region's peak design-day ambient, not just the average.

Dual-zone models are the more specialized selection - they earn their premium when a plant genuinely needs two different process temperatures (for example, a colder fermentation loop and a warmer general process loop) and would otherwise be running two separate outdoor units. If the whole plant runs on one temperature, a single-zone unit is the simpler and less expensive package.
