HRS 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 six cooling capacities, air or water cooled refrigerant, and global power supply options. This model is compatible with 100 VAC power.

The HRS-R is the IP54 rated variation of our popular HRS compact recirculating chiller. Upgrades include an IP54 electrical box and IP67 cable entries on the back panel. Additionally, the entire paneled housing is comprised of coated metal to resist degradation from oil mist, with an available stainless steel option for greater corrosion resistance. An optional 12L circulating coolant return tank can be selected. This tank has a capped opening separate from the fill port for easier cleaning when necessary. Finally, the ambient temperature upper limit has been increased to 45°C. The HRS-R shares many features with the standard HRS, including common overall dimensions, caster wheels for mobility, an angled fill port with a level indicator for the fluid tank, and a heating function. A magnet pump eliminates leakage and seal replacement. The dustproof filter is removable for cleaning without tools. The refrigerant is air cooled. If an external PF3W flow sensor is desired, a 24VDC power supply is available at the rear.

The HRS090 is a compact chiller with large cooling capacity. A 9.0kW air cooled or 10.5kW water cooled refrigeration circuit can be selected. The chiller package also contains the coolant circuit, including pump, tank, heat exchanger, and sensor monitored flow path. Set temperatures are PID controlled, while the system is monitored for 41 alarms. Additional features include a heating function, serial communications, and lockable casters for indoor mobility.

HRS high capacity standard chillers offer cooling capacities of 10 and 15 kW. Coolant and refrigeration circuits are included in a compact package. Air and water cooled versions are available. Set temperatures are PID controlled, while the system is monitored for 42 alarms. Additional features include a heating function, serial communication, and IPX4 ingress rating for outdoor installation.

The HRSH090 is a compact chiller with large cooling capacity. A 9.5kW air cooled or 11kW water cooled refrigerating method can be selected. The system is controlled with a triple inverter, offering premium energy savings. Inverter technology allows precise delivery of fan, compressor and pump performance instead of less efficient ON/OFF cycling. The operation interface includes an input keypad and digital display, and an angled fluid supply port with level check. Filter replacement is tool-less for the air cooled model. Power supplies are available in 200 and 400 VAC 3-phase, and function in both 50 and 60 Hz environments for global compatibility. Alarms report on a variety of circuit and equipment conditions to preserve optimal operation.

HRSH Air-cooled recirculating chillers offer a cooling capacity range of 10.5 to 28 kW. Coolant and refrigeration circuits are included in a compact and lightweight package. Extracted heat is air cooled. An inverter provides demand-based rotation control for the compressor, pump and fan, offering substantial energy savings. Electric options ensure global power supply compatibility. Additional features include a heating function, a low-maintenance seal-less immersion pump, and IPX4 rating for outdoor installation.

The HRSE recirculating chiller is a basic version of HRS featuring air cooled refrigerant and omitting the heating function. Three cooling capacities are available. The operator interface includes an easy-fill fluid tank with level check, intuitive keypad and digital display, and tool free filter removal. This model is compatible with single phase 100 VAC 50/60Hz power.
