HRS, HRS-R, HRSE compact recirculating chillers are designed to meet the widest range of single-point applications in both industrial and technology settings. The package design is robust enough for the factory, yet ergonomic and compact for lab installations. Coolant can be either heated or cooled within the set temperature range. Choose from eight cooling capacities, air or water cooled refrigerant, and global power supply options.

Large Capacity 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 Rack Mount Chillers are a temperature control device mountable in a 19-inch rack. Rack mounting recovers desktop or floor space, permitting stacking of related devices and mobility, depending on the rack style. Recirculating fluid removes heat from the process source. The heat is then removed from the fluid by an air or water-cooled refrigeration circuit. Coolant temperature stability is ±0.1°C within a set temperature range of 10 to 35°C.

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 DeviceNet^TM communications are optional.

HEC, HEF, 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 4.0 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.

The HEB is a thermoelectric circulating bath comprised of a controller and liquid tank.  Cooling is performed by a refrigerant-free peltier element, with extracted heat removed via facility water connection.  Temperature can be set from -15.0 to 60.0°C (flourinated fluid), achieving a distribution of ±0.2°C in the bath.  Abnormal heating and temperature sensor errors can be detected and reported.  Overall dimensions and power requirements are suitable for laboratory benchtop service.

The HED is a specialty recirculating chiller designed for direct temperature control of chemical liquids in the 300 to 750 watt capacity range.  The device consists of a controller and separate fluororesin heat exchanger.  An external circulation pump must be customer supplied.  Typical compatible fluids include hydrofluoric and sulfuric acid, copper sulfate solution, ammonia hydrogen peroxide, sodium hydroxide, and deionized or ozonated water.  A refrigerant-free, thermoelectric peltier element controls temperature from 10.0 to 60.0°C, with precision of ±0.1°C.  Extracted heat can be removed via facility water connection.  17 failure diagnostics can be displayed on the LCD display or read out over serial communication.
