Plant Support Equipment for Your Active Operations

Find the auxiliary equipment your production line depends on. From core plant systems, such as compressed air, to secondary packaging, we stock the machinery that helps keep your operation running efficiently.

Air Compressors

If your line runs pneumatic actuators or process air for your tooling, your air compressor is the foundation of your plant utilities. Compressor sizing ultimately depends on your peak CFM demand, duty cycle, and desired spare capacity for future growth. Undersized compressors are the most common cause of cycle-time drift across your line.

Compressor types Rotary screw, reciprocating (piston), centrifugal, scroll
Horsepower range 5 – 500+ HP
CFM output 15 – 2,500+ CFM
Pressure range 100 – 175 PSI standard; higher for blow molding
Est. used price range

$3,000 – $80,000+

Used vs. new savings

40–60% less than new

Typical for machines in good working condition

Who it’s for: : If you’re running plastics processing, packaging lines, or general manufacturing where your plant air pressure stability affects your cycle consistency, tool function, and conveying performance, a properly sized compressor with a matched dryer keeps your line from chasing pressure swings.

Brands we source: : Atlas-Copco, Kaeser, Ingersoll-Rand.

Air Dryers & Filtration Systems

If your compressed air carries moisture into your tools, actuators, or pneumatic conveying lines, you’ll see corrosion, freeze-ups in winter, and contamination of your product. Air dryers and filtration systems condition your compressed air, refrigerated dryers handle most plant duty, while desiccant dryers deliver the lower dew points your instrument air and critical processes require.

Dryer types Refrigerated, desiccant (heatless/heated), membrane, deliquescent
Dew point range +35°F to -100°F
Flow capacity 10 – 2,000+ SCFM
Filtration stages Particulate, coalescing, activated carbon
Est. used price range

$1,500 – $35,000+

Used vs. new savings

40–60% less than new

Typical for machines in good working condition

Who it’s for: : If you’re operating in a humid climate, running pneumatic equipment that’s sensitive to moisture, or producing parts where air contamination affects your product quality, a properly matched dryer is mandatory for your compressed air system.

Brands we source: : Airtek, Kaeser, and more.

Industrial Chillers & Cooling Systems

If your process equipment generates heat that affects cycle consistency, dimensional stability, or product quality, industrial chillers maintain the water temperatures your operation depends on. Proper sizing is based on your actual process heat load, required leaving-water temperature, ambient conditions, and future capacity requirements- not simply the tonnage of the equipment being cooled.

Cooling Capacity 5-500+ tons
Temperature Range 20°F – 80°F
Flow Capacity Typically 10-2000+GPM
Est. used price range

$15,000 – $120,000+

Used vs. new savings

40–60% less than new

Typical for machines in good working condition

Brands we source: : Hayssen, Bartelt, Triangle, Ilapak, Rovema, Bosch (Doboy/SIG), Matrix, Mespack.

Vacuum Pumps & Negative Pressure Systems

If your material conveying or central vacuum loaders depend on consistent negative pressure, vacuum pumps are the system your line relies on. Pump selection depends on your required vacuum level (inHg), flow rate (ACFM), and duty cycle, and on whether you need oil-flooded, dry, or liquid-ring technology for your application.

Pump types Rotary vane (oil-flooded), dry claw, liquid ring, regenerative blower, lobe
Vacuum range 0 – 29.9 inHg
Flow range 10 – 1,500+ ACFM
HP range 1 – 100 HP
Est. used price range

$1,500 – $40,000+

Used vs. new savings

40–60% less than new

Typical for machines in good working condition

Who it’s for: : If you’re operating central material conveying networks, thermoforming lines, or packaging operations with vacuum-pickup, a vacuum pump matched to your actual demand keeps your line stable without wasting energy on oversized capacity.

Brands we source: : Becker, Busch, Rietschle, Travaini, Edwards, Conair, Wittmann.

Material Handling Equipment

If your line depends on moving raw material or tooling between stations without manual bottlenecks, material handling equipment is the connective tissue of your plant. This category covers everything from resin conveying loaders and central station controllers to chain hoists, hand trucks, and reach trucks that move your finished goods to the dock. 

Equipment types Conveyors, separators, loaders, receivers, hoists, hand trucks, reach trucks, tilters, dumpers, hoppers, bins
Capacity range 500 lb – 6,000+ lb (forklifts); 1 – 50 ton (hoists)
Drive type Electric, pneumatic, hydraulic, manual
Est. used price range

$500 – $40,000+

Used vs. new savings

40–60% less than new

Typical for machines in good working condition

Who it’s for: : If you’re scaling your plant, replacing aging handling equipment, or building out a new dock or production cell, a mix of new and used handling equipment matched to your duty cycle is the most cost-effective way to expand without overspending on units that sit idle.

Brands we source: : Vestil , Mitsubishi, Budget, Caldwell, Thern, Global Industrial and other industrial material-handling manufacturers.

Dust Collection Systems

If your processes generate airborne particulates, granulator fines, pellet dust, regrind, or compound dust, dust collectors keep your air quality compliant with OSHA limits, protect your workers, and prevent fines from accumulating in your equipment and finished product.

Collector types Cartridge, baghouse, cyclone, wet scrubber, downdraft tables
Air volume 500 – 50,000+ CFM
Filtration efficiency 99.9%+ at 0.5 micron (HEPA available)
Cleaning method Pulse-jet, reverse air, shaker, mechanical
Est. used price range

$3,000 – $60,000+

Used vs. new savings

40–60% less than new

Typical for machines in good working condition

Who it’s for: : If you’re processing regrind, running granulators, or handling additives where airborne dust affects your worker safety, OSHA compliance, or product contamination risk, a properly sized dust collection system protects both your people and your line.

Brands we source: : Donaldson Torit, Camfil, Nederman, Robovent, Farr

Electrical Infrastructure

If you’re expanding your plant, adding new equipment, or replacing aging electrical gear, used transformers and electrical infrastructure deliver substantial savings versus new, provided each unit is tested for winding integrity, insulation resistance, and turns ratio before installation. 

Equipment types Dry-type/oil-filled transformers, switchgear, distribution panels, MCCs, VFDs
kVA range 15 – 5,000+ kVA
Voltage 120 – 34,500V (480V most common industrial)
Est. used price range

$2,000 – $50,000+

Used vs. new savings

40–60% less than new

Typical for machines in good working condition

Who it’s for: : If you’re commissioning new equipment that requires additional capacity, replacing failed gear, or building out a new line, a tested used transformer matched to your kVA requirement avoids the 6–12 month lead times typical for new electrical infrastructure.

Brands we source: : Delta Transformers.

Stretch & Pallet Wrappers

If you’re shipping palletized goods, stretch wrappers and pallet wrappers secure your load with stretch film for transit,  protecting your product from shifting, contamination, and damage during freight. These are auxiliary plant equipment (not packaging machinery), and sit at the end of your line before your shipping dock. 

Wrapper types Turntable (rotary), rotary arm, orbital, low-profile, semi-auto, fully automatic
Load capacity 1,000 – 6,000+ lb
Speed range 15 – 100+ loads/hour
Est. used price range

$2,000 – $25,000+

Used vs. new savings

40–60% less than new

Typical for machines in good working condition
