Advantage Outdoor Air-Cooled Central Chillers

5 to 210 Tons, Single & Dual Zone

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

Overview

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 150 tons, single- or dual-zone, with complete part numbers and specs.

Configuration Capacity Range Notes
Single Zone ~5 to 55 tons One chilled-fluid temperature plant-wide
Dual Zone ~10 to 190+ tons Two independent fluid temperatures from one frame

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.

Before You Request a Quote

Give us these and the quote comes back sized correctly the first time:

  • Cooling load in tons, or flow rate and required temperature rise
  • Target leaving fluid temperature(s) - one zone or two
  • Site ambient design conditions (winter low, summer high)
  • Pad location, rigging access, and available electrical service
  • Glycol requirement, if any, and target percentage

Outdoor Air-Cooled Chiller FAQ

The cabinet, electrical enclosures and controls are rated for outdoor duty as shipped. Sites with severe wind-driven rain, coastal salt exposure, or very low winter ambients should flag those conditions at quote time so the low-ambient control package and cabinet finish are matched to the site.

Dual-zone is worth it when both loads exist on the same site and neither is large enough to justify its own full chiller - one compressor plant, two independent fluid circuits. If either zone is large on its own, two single-zone units (or a single-zone plus a portable) may price out better and give you independent redundancy.

Yes - published tonnage figures are referenced to a specific leaving fluid temperature (commonly 50°F). Pulling the setpoint down toward the low 20s°F for a brewery or process load reduces the compressor's effective capacity at that same frame size, which is why leaving temperature needs to be confirmed before comparing models on tonnage alone.

The reservoir and pump station are built onto the outdoor frame on most Advantage models in this range; very large or custom dual-zone configurations may call for a separate pump tank station instead. Confirm which arrangement applies to your tonnage at quote time.
