Industrial Chiller Types

Air-cooled chillers reject heat through outdoor coils and fans. Water-cooled chillers typically connect to condenser-water systems and cooling towers. That distinction affects placement, included equipment, weather exposure, disconnection, lifting, and buyer fit.

Provide photographs of coils, fans, tube heads, pumps, starters, drives, panels, and all accessories offered with the machine. State whether associated towers or pumps are included or handled separately.

• Air-cooled packaged units
• Water-cooled central plant chillers
• Evaporative or hybrid configurations
• Trailer-mounted and temporary packages

Centrifugal, screw, scroll, reciprocating, absorption, and oil-free magnetic-bearing systems have different service histories, component values, operating evidence, and reuse considerations. Modular systems also require a complete module and control inventory.

The exact model matters more than a broad category. Document compressor count, motor or drive arrangement, controls, refrigerant, starts or hours when available, service events, and known faults.

• Centrifugal
• Rotary screw
• Scroll and modular
• Absorption
• Oil-free magnetic-bearing

A packaged air-cooled unit at grade may be close to transport-ready. A large water-cooled machine inside a central plant may require disassembly, specialized movement, or structural planning. A modular plant may move in sections but require careful inventory and protection.

Use equipment type as the beginning of the review. Condition, completeness, access, schedule, location, and current market demand still determine the commercial result.
