Product Description
Designed to be the premier solution for any European climate, LIRA meets all of your heating needs whilst also addressing the increasing demand for cooling comfort. These priorities are seamlessly integrated with the increasingly stringent energy efficiency and emission requirements.
The outdoor LIRA unit offers a veriable-speed scroll compressor with new advanced injection technology, allowing it to continue operating reliably even at -20°C.
Heating and Cooling in One System
With up to 50kW heating capacity, the LIRA also provides up to 42 kW of cooling during summer. Designed for all European climates, this system ensures optimal comfort and top performance in every season.
Being an air-to-air heat pump, direct heat is exchanged between the outdoor and indoor units via refrigerant, which maximises the efficiency of both heating and cooling modes. Because of this, no water circuit is needed, mitigating the risk of freezing as well as reducing thermal inertia, and allowing for quick adjustments in order to maintain optimal comfort.
Whisper-quiet comfort
The LIRA indoor units features fans that have been specially selected to minimise noise, ensuring a quieter working environment. You can choose between free-blowing models or ducted models to meet your specific requirements.
Both the outdoor and indoor units operate at an exceptionally low noise level of just 38 dB(A) and 30 db(A). A comfortable working environment has never been this effortless- and your visitors, customers, and surroundings will appreciate it too.
Flexible installation & Smart control
Whether you choose a free-blowing indoor unit with an axial fan or a ducted module with a plug fan, both options are EC-controlled and designed for low noise emission. The outdoor and indoor units can be positioned up to 30 metres apart, and with a single touchscreen panel, you can control up to 15 units. This ensures maximum flexibility and effortless installation.
Furthermore, the LIRA is ready for integration with smart grids and solar energy, allowing you to optimise energy use and reduce dependence on the electricity grid.
LIRA delivers a powerful gas-free solution for heating and cooling in industrial buildings – sustainable, efficient, and ready for tomorrow.

Technical Specification
Maximum efficiency, minimal consumption
With a COP of 4.38 and an EER of 4.00, the LIRA achieves the A+++ energy rating – the highest possible classification. This is made possible by cutting-edge technologies that enhance efficiency and perfomance:
- Optimised defrost cycle – Reduces both the frequency and duration of defrost cycles, keeping the system in heating mode longer.
- Pressure-controlled fan speed – Adapts to the level of frost buildup for more stable performance.
- Precision 2.5 mm fin spacing – Prevents ice formation and maximises heat exchanger efficiency.
Enhanced Vapour Injection (EVI): More power, less strain.
The LIRA utilises EVI technology, where vaporised refrigerant is injected into the compressor under high pressure. This results in:
•Greater energy efficiency and improved performance in extreme cold.
•Reduced strain on the compressor, extending its lifespan.
•Optimised operation with R32 refrigerant, an environmentally friendly choice that requires less charge and has zero ozone depletion potential.
