R290 Hybrid Inverter & EVI Air to Water Heat Pump

DEAKONET A3 Pro hybrid inverter EVI (Enhanced Vapor Injection) heat pump offers several advantages compared to  traditional heat pumps.

– Higher Efficiency

-Cold-Climate Performance

-Improved COP

-Extended Heating Season


-Quiet Operation

-Advanced Control Options



– Higher Efficiency:

Inverter technology enhances the efficiency of heat pumps, especially at lower outdoor temperatures. It allows the heat pump to maintain higher heating capacity and efficiency even when the weather is extremely cold. This results in reduced energy consumption and lower operating costs.


– Cold-Climate Performance

EVI heat pumps are well-suited for cold climates where temperatures can drop significantly below freezing. They can provide consistent and reliable heating even in extreme cold conditions, making them ideal for regions with harsh winters.

– Improved COP

Coefficient of Performance (COP) is a measure of a heat pump’s efficiency. A3 Pro Hybrid inverter & EVI heat pumps typically have a higher COP compared to single inverter or single EVI heat pumps, meaning they produce more heat energy for a given amount of electrical energy input. This leads to energy savings.

– Versatility

A3 Pro Hybrid inverter EVI heat pumps are versatile and can provide both heating and cooling, making them suitable for year-round use. They can also be used for domestic hot water production when equipped with a storage tank.


– Quiet Operation

A3 Pro hybrid inverter & EVI heat pumps are designed for quiet operation, which is important for maintaining a peaceful indoor environment. Low noise levels ensure minimal disruption to occupants.

Two-stage supported compressor shock absorption system

The advantage of a two-stage supported compressor shock absorption system is that it significantly reduces vibrations and noise generated by the compressor during operation. This system employs two stages of shock absorption, which effectively dampens the vibrations and ensures a quieter and more stable operation of the compressor. This reduced vibration and noise level contribute to a quieter and more comfortable environment for users, making it ideal for applications where noise reduction is essential, such as residential heating and cooling systems.


– Advanced Control Options

Intelligent Inverter Controller

A3 pro Inverter controllers continuously adjust the compressor speed and heating/cooling capacity based on the actual load requirements. This results in significant energy savings because the system operates at lower speeds when full capacity is not needed, reducing energy consumption and utility costs. It also offers precise temperature control by modulating the compressor’s speed and output. This ensures that the indoor environment remains at the desired temperature, minimizing temperature fluctuations and improving comfort. A3 Pro inverter controllers are compatible with remote monitoring and control systems, enabling users to manage their HVAC systems remotely, enhancing convenience and energy management.

– IOT Platform

IoT (Internet of Things) platforms are comprehensive software solutions designed to facilitate the development, management, and deployment of IoT applications and connected heat pumps.

Device Management: IoT platforms offer tools for managing a heat pump range of IoT devices, including provisioning, configuring, monitoring, and updating firmware remotely. Device management ensures the security, reliability, and scalability of IoT deployments.



Data Ingestion**: IoT platforms enable the collection of data from connected heat pumps. This data can include sensor readings, operating parameters and other information generated by IoT endpoints.

Hybrid Inverter & EVI Compressor

A hybrid inverter with an EVI (Enhanced Vapor Injection) compressor is a combination of  two advanced technologies used in heat pump and air conditioning systems:

  • Inverter technology allows the compressor to vary its speed and capacity based on the heating or cooling load. This modulation of speed results in higher energy efficiency, precise temperature control, reduced wear and tear, and quieter operation.
  • EVI technology uses vapor injection technology to enhance their heating capacity. By injecting additional refrigerant vapor into the compression process, they can produce more heat, improving efficiency and performance in very cold conditions.

SWEP Plate Heat Exchanger

SWEP is a well-known manufacturer of plate heat exchangers, and their products offer several advantages in various applications. The advantages of SWEP plate heat exchangers include:

  • High Heat Transfer Efficiency
  • Compact Design


  • Flexible Configuration
  • Low Fouling and Maintenance
  • Wide Temperature and Pressure Range
  • Energy Efficiency
  • Durable Construction

– Hydrophilic Finned Evaporator
A3 Pro series heat pump adopts hydrophilic fin evaporators which offer several advantages in air conditioning and refrigeration systems due to their unique design and characteristics.

DC Fan Motor

  • Energy Efficiency: DC fan motors are generally more energy-efficient than AC motors. They consume less power for the same level of performance, which can result in significant energy savings over time.
  • Variable Speed Control: DC fan motors can be easily controlled to adjust their speed. This allows for precise and flexible airflow control, making them suitable for applications where varying airflow is required.
  • Quiet Operation: DC fan motors tend to operate more quietly than AC motors, especially when running at lower speeds. This makes them ideal for applications where noise reduction is important, such as in residential HVAC systems or office equipment.

R290 Refrigerant

  • R290 is a hydrocarbon refrigerant also known as propane. It belongs to the alkane family and is composed of carbon and hydrogen atoms. R290 is a natural refrigerant, meaning it is not synthetic and does not contain chlorine or fluorine. It has gained attention in the refrigeration and air conditioning industry as an environmentally friendly alternative to some of the traditional synthetic refrigerants with high global warming potential (GWP)
