Comet Inverter 123-120R Heat Pump ABS (18.5kW)

Description

Comet Inverter 123-120R Heat Pump ABS (18.5kW)

The Comet Inverter 123-120R Heat Pump ABS (18.5kW) is a high-performance R32 heat pump from the Comet/Solarwise range, specifically selected for its aquaculture suitability. Featuring an all-titanium heat exchanger, this unit provides outstanding corrosion resistance for saline, brackish and chemically treated aquaculture water environments. Unlike standard copper heat exchangers that corrode rapidly in aquaculture conditions, the titanium heat exchanger offers a 25 years warranty and exceptional long-term durability.

A key advantage of the Comet range for aquaculture is the combined heat and cool capability. This makes these units ideal not just for winter heating but also for summer temperature management — critical for cold-water species including trout, salmon and abalone that require cooling during Australian summers. Heat pumps also offer significantly lower operating costs than electric resistance heaters, making them the most energy-efficient choice for RAS and intensive aquaculture heating.

The inverter-controlled compressor provides the most stable water temperatures achievable — critical for sensitive aquatic species. Inverter heat pumps modulate their output continuously to maintain a precise setpoint, avoiding the temperature swings associated with fixed-speed units.

Technical Specifications

Titanium Heat Exchanger Aquaculture Advantage

All Comet and Miracle heat pumps feature an all-titanium heat exchanger — a critical feature for aquaculture applications. The titanium construction resists corrosion from saltwater, brackish water, ozone, disinfectants and other chemicals commonly used in aquaculture systems. This directly protects your aquatic stock from metal leaching and ensures the heat exchanger maintains full performance over its long service life. The 25 years heat exchanger warranty provides peace of mind for commercial operators making a significant capital investment.

Heat + Cool Capability for Year-Round Aquaculture

Unlike simple heaters, the Comet range provides active cooling as well as heating. This dual capability is essential for cold-water species (trout, salmon, abalone) that require active chilling during Australian summers, and for any aquaculture operator who needs to maintain precise temperatures year-round regardless of ambient conditions. The ability to both heat and cool from a single unit simplifies system design and reduces capital expenditure compared to separate chiller and heater installations.
