Engineered air-cooled and water-cooled chiller packages, sized and built on 25 years of heat transfer equipment expertise, to hold precise process temperatures under the toughest continuous industrial duty.
An industrial chiller removes heat from a process fluid — water or a water/glycol mixture — and rejects that heat to the atmosphere, so that closed-loop cooling water can be recirculated to injection molding machines, reactors, heat exchangers, laser and welding equipment, data center CRAC/CRAH units, and other process loads at a controlled, repeatable temperature. Unlike comfort-cooling HVAC systems sized for a building's peak day, industrial process chillers are sized and built for continuous, often 24/7 duty against a fixed thermal load, with far tighter setpoint tolerances and much higher reliability expectations.
Fintelius engineers and fabricates complete chiller packages — air-cooled and water-cooled, scroll, screw, and centrifugal compressor technology — sized to the client's actual process duty, ambient design conditions, and site utilities, then integrates the unit with the piping, controls, and instrumentation package it will operate alongside in the field.
Every mechanical chiller — air-cooled or water-cooled — runs the same basic refrigeration cycle. The difference is only in how and where the heat is finally rejected to the environment.
Warm process water returns to the evaporator, where low-pressure liquid refrigerant absorbs heat and boils into a low-pressure vapor, chilling the water in the process.
The compressor (scroll, screw, reciprocating, or centrifugal) draws in the low-pressure refrigerant vapor and compresses it into a high-pressure, high-temperature gas.
The hot, high-pressure gas passes through the condenser. In air-cooled units, fans force ambient air across finned coils; in water-cooled units, condenser water carries the heat to an external cooling tower.
The now-liquid, high-pressure refrigerant passes through an expansion valve, which drops its pressure and temperature before it re-enters the evaporator.
Cooled process water is pumped out to the connected process loads, and the cycle repeats continuously to hold the setpoint temperature.
Compressor selection drives capacity range, part-load efficiency, and maintenance profile — Fintelius specifies the technology that fits the actual duty cycle, not a one-size package.
Piston-driven compressors well suited to smaller, variable-load facilities; typical capacity range of roughly 2–200 tons with proven reliability and simple field service.
Two interleaving spiral scrolls compress refrigerant with fewer moving parts, low vibration, and strong part-load efficiency; typically staged in modules from 5–150 tons.
Twin helical rotors deliver continuous, high-efficiency compression for demanding duty cycles; capacities typically span 20–450 tons, extending to 400+ tons in heavy industrial packages.
High-speed impellers, including magnetic-bearing, oil-free designs, give a compact footprint at large capacity, generally starting around 150 tons and scaling into the thousands of tons.
Thermally driven cycles that use waste heat, steam, or hot water instead of mechanical compression — well suited where low-cost heat is available and electrical load must be minimized.
Self-contained units rejecting heat directly to ambient air through condenser fans — no cooling tower, no process water treatment, faster installation, smaller plant footprint.
Condenser water circulates to an external cooling tower, giving higher efficiency and more stable performance across ambient swings, at the cost of tower maintenance and water treatment.
Multiple independent refrigeration circuits within a single package provide built-in redundancy and staged capacity control to match part-load conditions.
Purpose-built circuits handling water/glycol mixtures for process duties down to -50°C, used in chemical, pharmaceutical, and specialty processing applications.
The core of the refrigeration cycle, available in hermetic (sealed) or open-drive configurations depending on serviceability requirements and duty.
Copper-tube, aluminum-fin coils (air-cooled) or shell-and-tube bundles (water-cooled) that reject compressed refrigerant heat to air or condenser water.
Shell-and-tube, plate, or tank-coil heat exchanger where refrigerant absorbs heat from the circulating process water.
Meters refrigerant flow into the evaporator to match the actual cooling load, maintaining efficient superheat control.
Removes moisture and particulate from the refrigerant circuit to protect the compressor and expansion device from contamination damage.
Variable-speed fans on air-cooled units, or a tower water interface on water-cooled units, matched to the design ambient wet/dry-bulb conditions.
Automates compressor staging, safety interlocks, and setpoint control, with graphic display, trending, and BAS/SCADA communication.
High/low-pressure switches, anti-freeze protection, overload relays, and flow switches guard the refrigeration circuit and pump set.
Primary (and secondary, where required) pumps sized to the process flow rate and system head, often supplied as an integrated skid.
The single biggest chiller decision is how the unit rejects heat — each path carries different trade-offs in efficiency, footprint, water use, and long-term operating cost.
Correct chiller sizing is driven by more than peak cooling load. Fintelius's engineering team accounts for the full set of conditions the unit will actually operate under, so the package delivers rated capacity in the field, not just on a datasheet.
