Chillers and Temperature Control Equipment
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.

HRSH recirculating chillers offer a cooling capacity range of 10 to 28 kW. Coolant and refrigeration circuits are included in a compact and lightweight package. Extracted heat can be air or water cooled. An inverter provides demand-based rotation control for the compressor, pump and fan (air cooled model), offering substantial energy savings. Electric options ensure global power supply compatibility.
Additional features include: Heating Function, Low Maintenance Seal-less Immersion Pump, and IPX4 Rating for Outdoor Installation.
The HRL and HRLE are temperature control devices featuring two cooling channels in one package. These chillers are specifically designed to cool the optical head and oscillator of a laser processing system. Considerable space savings can be realized compared to a two chiller solution. Both types feature touch panels for operations, fan-cooled refrigeration circuits, and independent coolant ports for each laser component. The HRL has extensive standard features and targets large output lasers of 5kW or more. The HRLE is for medium output lasers of 3-4kW, with a patent pending simplified circuit design for a single tank and pump. The heating function uses waste heat from the refrigerant discharge instead of a separate electric heater to improve efficiency and reliabilty.
HRZ-F recirculating chillers are especially suited for high technology sectors, by conforming to several SEMI equipment standards and regulating fluid temperature to ±0.1°C. Both the pump and compressor rotations are inverter controlled for energy efficiency. Refrigerant is R410A, compliant with current EU F-gas regulations. This model is compatible with fluorinated coolants including Fluorinert™ and GALDEN®.
HRW heat exchangers are refrigerant free and use no compressor. This energy efficient design saves further by using an inverter pump for demand-based rotation control. Four models offer cooling capacities from 2 to 30 kW. The HRW is rated for high performance temperature stability of ±0.3°C through a set range of 20 to 90°C. The operation panel includes an input keypad and multi-line LCD display. 23 alarms report on a variety of circuit and equipment conditions to facilitate optimal operation. In addition to standard I/O and RS-485 serial communications, analog and DeviceNetTM communications are optional.
HEC and INR recirculating chillers satisfy low capacity temperature control demand in the range of 140 to 1200 watts. A refrigerant-free, thermoelectric peltier element controls temperature from 10.0 to 60.0°C, with precision of ±0.01°C under stable load conditions. Extracted heat can be air or water cooled. 15 alarms support functional troubleshooting, and can be observed on the LCD display or over serial communication. Low noise and vibration, compact dimensions and flexible power requirements are suitable for laboratory benchtop service.
