BENEFITS:

Direct Replacement of Oil and Gas Boilers

The effiQueenc® UHT Cascade Series heat pumps enable the direct replacement of oil and natural gas heating systems, while maintaining the performance requirements of existing installations.

Hot water production up to 95 °C (203 °F) at outdoor temperatures as low as -20 °C (-4 °F), allowing the use of existing hydronic systems.

Compatible with high-temperature radiators, coils, and existing heat emitters.

No major modifications to existing distribution systems are required (flow rates and ΔT maintained), with the integration of a buffer tank or hydraulic separator.

✔ Ideal for energy retrofit and decarbonization projects

✔ Enables system conversion without replacing existing heat emitters

The modular design allows:

• Configuration of up to 8 units in hydronic cascade
• Alternating operation (rotation) of units based on runtime hours
• Staged start-up according to thermal load

✔ Improves overall system reliability and reduces wear

Advanced Intelligent Control and Simplified Operation

The effiQueenc® UHT Cascade Series heat pumps integrate an advanced control system designed to provide intelligent, precise, and intuitive operation management.

All system functions are managed by a programmable microprocessor, allowing fine adjustment of operating parameters based on the building’s actual requirements, either directly on-site or via the IoT platform. This approach ensures optimal adaptation to operating conditions and consistent performance.

The controller can be installed directly on the unit (standard configuration) or remotely inside the building using a wired controller.

The advanced control system provides:

• Precise adjustment of operating parameters
• A user-friendly interface for the operator
• Centralized management of multiple units
• Simplified day-to-day operation

Intelligent Weather Compensation Control

• Temperature curve modulated based on outdoor temperature
• Intelligent modulation control, optimizing efficiency according to actual demand

The integrated compensation curve automatically adjusts the water temperature based on outdoor conditions, ensuring both comfort and energy efficiency.

This function is fully configurable and can be enabled or disabled depending on system requirements.

Reliability and Durability

• Stable operation under extreme conditions –35 °C to 43 °C (–31 °F to 109 °F)
• Compliant with North American requirements

• Robust and durable design
• Industrial-grade components
