Lower Operating Costs. Sustainable Heating Solutions.

ATOR Premium Industrial Heat Pumps are engineered to provide efficient and reliable heating and cooling for a wide range of commercial and industrial applications, including greenhouses, manufacturing facilities, hotels, hospitals, livestock buildings, drying plants and other large-scale installations.

Combining advanced inverter technology, EVI compressor technology, intelligent control systems and high-efficiency heat exchangers, ATOR systems are designed to deliver dependable performance across demanding operating conditions.

The system continuously modulates its output according to the actual heating or cooling demand. By matching capacity to the required load, ATOR heat pumps help reduce unnecessary energy consumption while supporting quieter and more stable operation.

Why Choose ATOR Premium Industrial Heat Pumps?

ATOR combines high-efficiency heat pump technology with intelligent control and comprehensive protection systems to provide a dependable alternative to conventional heating solutions.

Wide Operating Range

ATOR heat pumps are designed to operate in heating mode across an outdoor temperature range of -36°C to +48°C, with hot water temperatures of up to 60°C.

For cooling applications, the operating range is 15°C to 55°C, with leaving water temperatures from 7°C to 30°C.

This wide operating envelope makes the system suitable for demanding commercial and industrial applications where reliable performance is required throughout the year.

Continuous Capacity Modulation

Advanced inverter technology enables the compressor capacity to be continuously modulated between 15% and 100%.

Rather than operating through frequent start-stop cycles, the system adjusts its output to match the actual load. This provides more precise capacity control, helps improve energy efficiency and can reduce unnecessary mechanical stress on the compressor.

The specified sound pressure level is 56 dB(A).

Rapid Heating Technology

The intelligent inverter control algorithm is designed to respond quickly when outdoor temperatures fall.

By accelerating the increase in water temperature, the system can help restore the required operating conditions more rapidly.

According to ATOR’s technical data, this technology can reduce heating time by up to 20%.

Advanced Protection Systems

Reliable operation is critical in industrial heating applications. ATOR heat pumps incorporate a range of protection functions designed to safeguard the system under demanding operating conditions.

Key protection features include:

• High and low temperature protection
• Inverter drive board protection
• Compressor protection
• EVI exhaust protection
• Anti-freeze protection

These integrated protection functions help maintain safe and stable operation while supporting the long-term reliability of the equipment.

Dual Independent Air Chambers

The unit incorporates two independent air chambers designed to provide greater operational flexibility and resilience.

The independent chamber configuration allows the chambers to support one another, helping maintain system availability during certain maintenance or fault conditions.

The design also supports the defrosting process and helps minimise fluctuations in water temperature during defrost cycles.

Intelligent Defrost Control

Frost formation can significantly affect the performance of an air-source heat pump in cold and humid conditions.

ATOR’s inverter units continuously monitor operating parameters to identify frost formation and initiate the defrost cycle when required.

The intelligent defrost system is designed to prevent unnecessary defrost cycles, helping maintain efficiency while reducing interruptions to normal operation.

Continuous capacity modulation also enables more precise control of water temperature during changing load conditions.

Automatic Load Regulation

ATOR heat pumps incorporate automatic load regulation technology to help maintain efficient operation under varying demand.

Where multiple compressors are installed, the system distributes the load between compressors to promote balanced operation.

This approach can help improve operating efficiency, reduce unnecessary compressor cycling and support longer component service life.

Intelligent Control and Remote Monitoring

ATOR heat pumps can be equipped with remote monitoring and control functionality, allowing operators to manage system operation without being physically present at the equipment.

Depending on the system configuration, users can access functions including:

• Start/stop control
• Temperature adjustment
• Scheduling
• Real-time alarm monitoring
• Historical fault records

DTU Remote Monitoring

The DTU monitoring system provides real-time access to equipment operating status and enables remote system control.

Through a web-based interface, operators can monitor the system remotely and respond quickly to alarms or changes in operating conditions.

ATOR systems also support Modbus RS485 / BMS communication, enabling integration with building management and control systems.

High-Efficiency Technology

ATOR Premium Industrial Heat Pumps incorporate a range of technologies designed to deliver efficient performance across demanding operating conditions.

EVI Compressor Technology

Enhanced Vapour Injection (EVI) technology is particularly beneficial in low-ambient heating applications.

By improving refrigerant performance at low evaporating temperatures, EVI technology helps maintain heating capacity when outdoor temperatures fall significantly.

This makes the technology well suited to industrial and commercial applications operating in challenging winter conditions.

High-Efficiency DC Fan Motor

The DC fan motor and variable-speed fan drive provide precise airflow control according to system demand.

By adjusting fan speed to the required operating conditions, the system can help reduce electrical consumption and operating noise while maintaining the required heat exchange performance.

Shell & Tube Heat Exchanger

The Shell & Tube heat exchanger is designed to provide efficient heat transfer and reliable operation in demanding industrial environments.

The heat exchanger has been tested at 5.0 MPa, supporting its suitability for applications where robust equipment performance is required.

High-Efficiency Inverter Drive

The inverter drive continuously adjusts compressor output according to the required load.

This enables the system to operate closer to its optimum efficiency point rather than running continuously at full capacity, helping to improve part-load efficiency and overall system performance.

Lower Operating Costs with Heat Pump Technology

Heat pump technology transfers thermal energy from the surrounding environment rather than generating heat solely through direct electrical resistance.

This makes it possible to deliver useful heating output while consuming significantly less electrical energy than conventional direct-electric heating systems, depending on operating conditions.

According to ATOR’s technical calculations, at an assumed outdoor temperature of -25°C, the estimated operating cost of the heat pump is approximately 60–70% of the cost of an electric heater.

As an electrically driven heating technology, the system can also be integrated with renewable electricity generation, such as solar PV, where site conditions permit.

This can provide an additional opportunity to reduce long-term energy costs and support wider decarbonisation objectives.

Heat Pump Solutions for 1,000 m³ Greenhouses

Selecting the correct heat pump capacity is essential for greenhouse applications.

Heat demand depends on a number of factors, including greenhouse volume, insulation level, outdoor temperature, target indoor temperature and operating conditions.

Based on ATOR’s calculations, assuming an outdoor temperature of -25°C and an indoor temperature of 30°C, the estimated heating requirements for a 1,000 m³ greenhouse are:

• Approximately 78.6 kW for a well-insulated greenhouse
