The VihoX-20AC 20HP air-cooled industrial water chiller delivers centralized industrial refrigeration for high-tonnage multi-station thermoforming lines, extensive cup machine production clusters, and sheet extrusion polishing roll stands. Displacing 55.3 kW (47,558 kcal/h) of continuous thermal energy with an 18.1 kW high-efficiency scroll compressor, it eliminates mold heat accumulation during heavy-gauge PP, PET, and barrier film container forming. A massive 350-liter SUS304 stainless steel insulated reservoir provides immense thermal inertia.
Engineered for demanding plant duty, the VihoX-20AC circulates 9.48 m³/h of chilled coolant through DN40 process piping under 20 meters of head, driven by a heavy-duty 1.5 kW pump. Six front-mounted analog gauges continuously monitor refrigerant suction/discharge and multi-point water pressures. Overhead high-volume fans displace 20,000 m³/h of ambient air through heavy copper-tube aluminum-fin condensers, ensuring robust continuous operation in hot industrial climates without cooling tower water losses.
To ensure reliable field startup, every VihoX 20HP cooling unit is subjected to rigorous dynamic factory benchmarking. Inspection personnel verify scroll compressor oil return, confirm 9.48 m³/h volumetric water displacement, and test electrical overload disconnect relays under sustained full-tonnage loads.

| Recommended Facility Match | 1 large three-station thermoformer (such as 710×900) or a cluster of multiple cup machines | Ideal for VihoX 710×900 3-station thermoformers or multi-machine clusters |
The VihoX-20AC is designed for large three-station thermoformers like the VihoX 710×900 negative-pressure machine, or a battery of 2 to 3 automated cup making machines sharing a common chilled water manifold.
The air-cooled VihoX-20AC requires no water treatment chemicals, no cooling tower maintenance, no Legionella monitoring, and zero water consumption, making it clean, easy to install, and ideal for water-scarce regions.
Large thermoforming molds contain high internal thermal mass; the 350L reservoir buffers sudden heat surges when deep-draw molds cycle, preventing temperature spikes from altering plastic part shrinkage tolerances.
Yes, its 55.3 kW rating allows it to handle the combined cooling load of a compact sheet line roll calender and an adjacent cup making machine when overall thermal demands are properly balanced.
Safety circuits include internal thermal motor protectors, high/low pressure switches with manual resets, oil level sight indicators, phase-loss monitors, and an automatic anti-freeze thermostat cut-off.
The scroll compressor is mounted on specialized anti-vibration damping pads inside an acoustically lined lower compartment, while low-RPM aerodynamic overhead fan blades keep workshop sound levels within acceptable industrial limits.
Routine maintenance consists of weekly air filter blow-downs, monthly water strainer cleaning, quarterly refrigerant pressure log reviews, and an annual visual inspection of electrical contactors.
Yes, if your facility requires pumping chilled water across long pipe runs or overhead factory piping bridges, higher-head 2.2 kW or 3.0 kW booster pumps can be factory-fitted upon request.
With decades of industrial plastic machinery manufacturing expertise, VihoX delivers comprehensive turnkey production lines—combining sheet extruders, cup forming units, scrap recovery systems, and centralized chilling plants into dependable packaging facilities.

At this size the chiller trims temperature rather than carrying the whole load, which makes a VihoX 120 ton cooling tower the sensible partner. Pair it with a 50HP PM VSD compressor where pneumatic demand is high; large cup making machines and multi-zone formers are the typical hosts.
