REVERE CO₂ Air to Water Heat Pump

• Flexible – The same system can be simultaneously used for Space Heating & Domestic Hot Water
• Ultra quiet operation – 60dBa
• No combustion – reduces fire risk
• Suitable for up to 60°C ΔT (flow 90°C, return 30°C)
• Suits Australian conditions – accommodates ambient operating temperatures from -5°C to 43°C (Special unit available for -15°C or -20°C)
• Safe – Non-flammable CO₂ refrigerant
• Programmable – can be set to operate during off peak times to benefit from low cost power
• 30% Space Saving due to Y Frame design (CHP-80)
• Versatile – Suitable for a wide range of purposes, from small facilities to large buildings where hot water or heating is required
• Eco friendly – The Revere® CO2 Heat Pump uses natural CO₂ refrigerant. This refrigerant has a global warming potential (GWP) of about 1/1700 that of R410 and zero ozone-depleting potential (ODP)
• Energy efficient – Under optimal conditions, Revere® CO2 Heat Pumps achieve an exceptional coefficient of performance (up to 4.2) which equates to higher energy efficiency. Compared to the traditional electric hot water heater, the CO2 hot water heat pump can save up to 75% heating energy. Further energy cost savings can be achieved through operation during off peak hours, subject to off-peak electrical power supply
• Anti-freeze/Cold Area Units – the heat pump is fitted with a defrost solenoid valve which will open when the evaporator ices up. The hot gas will then flow through the evaporator and melts the ice. Water cannot be stored during defrosting
• Heats up to 90°C – Due to its innovative design, the Revere® CO2 Heat Pump can produce hot water up to 90°C at low and high ambient temperatures (-20°C to 43°C)
• One pass heating – It is suitable for heating water from low to high temperatures (large temperature difference) in one pass
• Reduces storage requirements – Since this hot water heat pump can heat water up to 90ºC, the size of the storage tank can be reduced

• Energy Saving Function – This function is an energy saving function that learns operation patterns from the four previous weeks to prevent unnecessary heating and temperature decreases in stored water through natural heat loss. The use of this function based on operation data stops the unit from boiling water unnecessarily.

Revere™ CO2 offers Significantly lower running costs & CO₂ emissions.

Advantages of using CO₂ as a refrigerant

This heat pump uses CO₂ as a refrigerant. CO₂ is a natural refrigerant and has an ozone depletion potential (ODP) of zero and a global warming potential (GWP) of 1. CO2 refrigerant is a non HFC refrigerant. Traditional HFC refrigeration systems affect climate change in two distinct ways: direct and indirect contribution. Direct contribution results from the release of refrigerants into the atmosphere. Indirect contribution refers to the energy used to operate traditional refrigeration equipment. The less energy required to operate the equipment, the lower the impact on the environment.
