The VihoX-3AC 3HP air-cooled industrial water chiller delivers steady closed-loop thermal stabilization for compact plastics tooling, prototype thermoformers, and sensitive auxiliary hydraulics. Built around a hermetic scroll compressor rated at 2.2 kW, this standalone chiller extracts up to 6,966 kcal/h of process heat without requiring a dedicated external cooling tower. An integrated 60-liter SUS304 stainless steel reservoir prevents process water contamination while evening out thermal surges during high-cycle sampling or continuous shallow-draw container production.
Designed with a compact 960 × 630 mm footprint and heavy-duty locking casters, the VihoX-3AC fits alongside cramped production cells or prototyping bays. Its thermostatic expansion valve precisely meters refrigerant to match dynamic mold temperature swings between 5°C and 35°C, sustaining ±1°C accuracy. The multi-protection electrical architecture monitors compressor discharge pressure, motor phase alignment, and minimum water circuit flow, automatically disengaging the refrigeration cycle before coil icing or pump cavitation occurs.
Prior to container loading and export crating, each VihoX 3HP chiller is operated continuously across a multi-hour thermal verification cycle. Our quality control team measures starting current spikes, confirms smooth refrigerant boiling inside the coil, and monitors digital thermostat response curves against laboratory heat loads.

The VihoX-3AC is specifically engineered for single-mold pilot thermoformers, blister laboratory sampling equipment, desktop vacuum forming machines, or cooling hydraulic oil circuits on small cup forming units requiring under 8.1 kW of heat dissipation.
Yes, its heavy-duty finned condenser is swept by an axial fan circulating 3,000 m³/h of ambient air, maintaining full cooling capacity in workshop ambient temperatures up to 43°C when clear airflow clearance is provided around the intake louvers.
No external pump is needed. The unit integrates a factory-installed 0.37 kW centrifugal circulation pump delivering a 20-meter discharge head, supplying 1.4 m³/h through 3/4-inch DN20 process ports directly into the mold cooling channels.
Unlike carbon steel tanks that shed rust particles into micro-channel mold cooling passages, our 60L SUS304 vessel guarantees clean water delivery, preventing scale accumulation, galvanic corrosion, and clogged heat-transfer passages inside aluminum or beryllium-copper molds.
While 3-phase 380V/50Hz is standard, VihoX builds the 3HP chiller with custom electrical panels for 220V/60Hz, 415V/50Hz, 460V/60Hz, or 480V/60Hz industrial power grids worldwide.
A digital microcomputer controller with dual digital readouts allows operators to dial setpoints from 5°C to 35°C, cycling the scroll compressor automatically to maintain steady ±1°C process water supply.
The electrical control cabinet features independent fault circuits for refrigerant high/low pressure, thermal compressor overload, reverse-phase detection, anti-freeze thermostat protection, and low-flow water cutoffs.
Yes, standard refrigeration components including Danfoss/Emerson expansion valves, AC contactors, filter driers, and pressure gauges are kept in stock for rapid express dispatch.
As a dedicated source manufacturer of thermoforming machinery and auxiliary systems, VihoX delivers tightly integrated processing cells—connecting sheet extrusion lines, cup and tray forming machines, inline granulators, and dedicated mold water chillers into seamless production loops.
