Advantage Titan Series Central Chillers

From 20°F to 80°F leaving fluid temperature, depending on the specific model and refrigerant. The achievable range differs slightly between the Scroll/R-454B models and the Screw/R-513A 150/180-ton frames, so confirm your exact process temperature with us before ordering. Treat the bottom of that range as glycol territory, since plain water stops being safe at about 48°F. Capacity also shrinks as the setpoint drops, which means a Titan picked off its standard rating for a 30°F process comes up short; give us the real temperature and we will rate the unit there.

Yes. Titan is the indoor central chiller platform, made to be installed in a mechanical room, with the compressor, evaporator, reservoir and pump sharing one frame; if you need a weatherproof outdoor package instead, see the OACS series. The room does not have to swallow condenser heat, because air-cooled models reject it through a remote outdoor section and water-cooled models into condenser water. What it needs is a floor drain near the open-top reservoir and a clear route for the supply and return headers.

They are different machines inside. TI-150WD and TI-180WD use large rotary Screw compressors on R-513A refrigerant, not the Scroll compressors and R-454B used across the rest of the Titan line, so treat their maintenance, oil-return and spare-parts needs as their own product line rather than an extension of the smaller models. The WD suffix also marks both as water-cooled and dual-zone, so each arrives with a condenser-water requirement and two setpoints to plan. A plant stepping up from a 120-ton Titan should budget for both: other compressor parts on the shelf, and tower or city water sized for the larger frame.

Start with the water, not the floor space. Air-cooled Titan units send their heat to an outdoor remote condensing section over a dedicated refrigerant line set - no tower, no plant water. Water-cooled units use city or tower water instead, for a smaller footprint and capacity that doesn't depend on ambient. The water figure surprises people: at the 3 GPM per ton common for tower condensers, a Titan carrying 120 tons circulates about 360 GPM, and once-through city water at half that ratio runs roughly 260,000 gallons a day around the clock. Our Air-Cooled vs Water-Cooled page covers the trade in more depth, or call and we'll weigh it against your mechanical room's actual constraints.

Most of the refrigerant side. Air-cooled Titan units are charged in the field rather than shipped with a full charge, so plan for a refrigeration contractor. That contractor furnishes the line set in refrigerant-grade copper only, brazed with high-temperature phos-copper and sized on equivalent length and allowable pressure drop. Their scope also covers discharge check valves, hot gas and liquid line shut-off valves, condenser-mounted relief valves and recovery ports, and inverted traps, plus line hangers near the coil on runs over 50 ft. A certified technician pulls the vacuum and charges the system under load. Indoors, the Advantage Titan section must sit where the room stays above 40°F.

Into an open-top reservoir. The From Process line is a rigid pipe through the lid on the hot side of the tank, ending about 1.5 ft above the tank bottom and cut on a diagonal facing away from the pump suctions, which keeps air out of the loop; To Process feeds your supply header. Two pumps are built in: a process pump rated at a nominal 2.4 GPM per ton - about 144 GPM on a 60-ton unit - and a separate evaporator recirculation pump, so evaporator flow holds steady when process flow varies. Specify piping for 100 PSI at 100°F, plus a 20 mesh basket strainer. Since the tank is open, overhead piping drains back into it at shutdown.

Yes. Every Titan runs on Advantage's MZC III multizone instrument, which can control up to six refrigeration circuits. Capacity is added by installing an APT-RC or WPT chilling module who's zone boards connect to the Titan's display board, so the plant still runs from one control. Each refrigeration circuit has its own zone board; if the display or one board fails, the other circuits keep running. Pump controls are panel-mounted and work independently of the chiller control, so process flow continues even while refrigeration is stopped. Modbus RTU or SPI is standard, with Modbus TCP and a remote display available as options. Leaving capped tees on the headers now makes that later module a short job.
