SMC Chillers and Temperature Control Product Line

Lots of variations are available according to the applications’ requirements.

Recirculating chillers and heat exchangers are installed to provide thermal stability for applications in industrial and applied sciences from laser cutting, welding, marking and plastic injection molding. Lab science and analytical equipment applications include: mass spectrometry, gas chromatography, MRIs, CT scanners, radiation therapy machines and other medical equipment.

Sizing of the chiller or heat exchanger is determined by the required cooling capacity measured in watts (W), kilowatts (kW), BTU per hour, or ton or refrigeration (RT); temperature stability or tolerance; and cooling method, refrigeration or Peltier effect.

SMC chillers are available in Rack Mount, Bench Top, or Floor Standing installations and are cooled with air or facility water; the recirculating coolant can be water, DI water, or an Ethylene glycol mixture.
