In an era of climate transition, Reznor continues to innovate. The new LIRA range delivers powerful and sustainable air-to-air heat pumps, providing gas-free warm air heating for warehouses and industrial buildings – whisper-quiet and highly efficient, even at temperatures as low as -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.
Whisper-quiet comfort
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.
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.
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.
