Efficiency and performance, naturally connected
No-compromise efficiency and performance
These are the main strengths of Heez, the result of continuous modulation of the variable-capacity rotary compressors (DC inverter), extremely high performance technology that CAREL has for the first time made available to the refrigerated merchandiser segment. DC rotary technology in fact ensures the highest energy performance due to the very wide range of modulation, as well as high reliability and stability, lower noise and more compact dimensions.Heez is therefore the response to the challenges that the industry will have to face in the near future in terms of reducing environmental impact and running costs, while still guaranteeing the required performance. In fact it is fundamental for drinks and similar products to be at the ideal temperature for sale at all times, meaning rapid cooling when opening the store or the bottle cooler, or when restocking the cooler. In addition to guaranteeing such high performance, Heez can ensure results in terms of energy savings that easily exceed the current market benchmarks and indeed anticipate future standards, using a natural refrigerant - propane - to achieve true natural efficiency.
Heez control solution can be applied to both glass door merchandisers and open front coolers.

Incredible energy and pull-down performance
The extensive modulation ensured by the Heez control solution achieves significant results both in terms of energy performance and pull-down.
In particular, rotary DC inverter technology significantly reduces both ON-OFF cycles in steady-state operation and slashes pull-down times due to the high motor operating speed. Control algorithms allow synchronised operation of the compressor, stepper valve and variable-speed fans, so as to ensure the best performance in climates.
Self-adaptive logic adjusts operating conditions during the day and overnight by learning from sales habits. Advanced algorithms identify the need for defrosting and adjust the set point according to actual unit demand.
All of these features have made it possible to achieve incredible results in pull-down performance and energy consumption. Tests conducted by a certified third-party laboratory have shown that the Heez control solution installed on a glass door merchandiser can reach an EEI (Energy Efficiency Index) of 13.8, meaning 50% better efficiency than the best beverage coolers available on the market.
