Advantage 2 to 15 Ton Portable Chillers

Air- or Water-Cooled

The workhorse Advantage MG range

Overview

The workhorse Advantage MG range for single-machine plastics, machine-tool coolant and mid-size process cooling.

This is the size range most single injection-molding presses, CNC machine tools and mid-size lasers actually need. Advantage MG units are available air-cooled for the simplest installation, or water-cooled where the mechanical room runs hot or floor space matters more than a condenser fan's footprint.

Remote-condenser (ARC) variants are available through this range: the compressor and pump stay at floor level next to the machine, and the condenser coil mounts outdoors or on a roof, connected by refrigerant lines. That keeps the noisy, heat-rejecting half of the chiller out of the production floor without moving to a full central system.

As with the smaller frames, tell us the actual heat load and required fluid temperature rather than working backward from a competitor's nameplate tonnage - a molding press's heat load depends on shot size, cycle time and material as much as clamp tonnage, and sizing from clamp tonnage alone is a common and expensive mistake. Every MG model in this tonnage range has its own part-number page with full specs; browse individual MG models to match the right one to your load.

  • Air-cooled, water-cooled, and remote-condenser (ARC) configurations
  • Factory-piped pump and reservoir - drop in place and connect
  • Suitable for single-press plastics, CNC coolant loops, mid-size lasers
  • EDM machine-cooling variants available in this range as well

Same MG chiller, three condenser arrangements - pick by where the heat can go.

Configuration Capacity Range Notes
Air-Cooled 2 to 15 tons Simplest install, no plant water connection
Water-Cooled 2 to 15 tons Smaller footprint, needs plant/tower water supply
Remote Condenser (ARC) 2 to 15 tons Compressor/pump indoors, condenser coil outdoors or on roof

Sizing From Heat Load, Not Clamp Tonnage

A common and expensive mistake in this range is sizing a chiller off the molding press's clamp-force tonnage rather than its actual process heat load. Clamp tonnage measures the press's clamping force; chiller tonnage needs to match the BTU/hr the mold and material actually generate, which depends on shot size, cycle time, material type and mold design. Two presses with the same clamp tonnage can need very different chiller sizes.

Every Advantage unit in this range ships factory-piped and pressure-tested - the reservoir and pump are already sized and plumbed to the compressor, so installation is a matter of setting the unit, connecting power, and running supply/return lines to the point of use.

Machine-Side Data

What We Need to Size Your MG Portable

MG units in this range are sized from actual heat load, not clamp tonnage, so the most useful thing you can send is the machine's real load:

  • Heat in BTU/hr or tons, or resin pounds per hour for a molding press
  • For a laser, the cooling requirement from its installation sheet
  • Fluid temperature the mold, tool coolant or laser needs, and the air temperature at the unit
  • Air-cooled, water-cooled, or an ARC condenser mounted outdoors
  • Voltage, phase and floor space beside the machine

Turning a press, laser or tool into a heat load

Start from pounds per hour of resin and the heat each pound must give up. Cooling a typical polyolefin from melt to ejection releases roughly 200 to 300 BTU per pound, so a press running 100 lb/hr puts about 20,000 to 30,000 BTU/hr, 1.7 to 2.5 tons, into the mold water. Other resins differ, so treat this as a cross-check rather than a selection. Count the hydraulic oil cooler as well when it is piped to the same chiller, and size for the shortest cycle the mold will ever run - the fastest cycle, not average output, sets the peak.

Usually not, because hydraulic oil runs happily on water far warmer than a mold needs. On many presses the oil cooler is a large share of total heat, and feeding it 50°F chilled water spends Advantage compressor capacity on a job that tower or plant water handles for a fraction of the energy. Very cold water can also overcool the oil at startup, which slows the hydraulics. Size the MG for the mold and put the oil cooler on tower water or a separate warmer circuit; send both heat figures if you are unsure which loop carries what.

Use the heat it releases, not the beam power. A fiber laser turns roughly 30 to 40% of its electrical input into light; the rest becomes heat in the water. A 6 kW fiber source can therefore reject about 9 to 14 kW, roughly 31,000 to 48,000 BTU/hr or 2.5 to 4 tons, before the cutting head and optics are counted. CO2 lasers convert far less of their input to light, so one with the same output needs a much larger chiller. The laser's installation sheet usually states its cooling requirement - send that sheet rather than the beam rating.

No - below the dew point the mold sweats. On a humid summer day plant air can carry a dew point in the upper 60s°F, so mold steel at 50°F collects condensation that spots parts, rusts cavities and drips onto the platen. Shops chase cycle time with colder water, then give it back wiping molds and sorting rejects. Run the warmest water that holds the cycle, dry the air around the mold if cold water is truly needed, and remember that every degree colder also takes capacity away from the chiller.
