Electronic Expansion Valve Leonardo Max presents as standard electronic expansion valve managed and optimized by on-board microprocessor. That allow the monitoring of all functional parameters of the cycle and their optimization in terms of maximum energy saving. This item permit to: Optimize the overheating Operate at lower condensation temperature respect to those permitted by normal thermostatic valves and thus increase unit COP Regulate the operative temperature with high accuracy Perform dehumidification keeping constant air flow

Electronic Expansion Valve Possibility to control superheating in a stable way in all running conditions, avoiding sudden variations typical of electromechanical thermostatic valves, due to a dedicated regulation.

Electronic Expansion Valve Under the control of UNIFLAIR Control System, the electronic expansion valve provides accurate control in order to ensure an increase in the COP at low external temperatures, because it enables the unit to operate at a condensing temperature much lower than 38°C dew point, making the most of compressor working range.

Electronic Expansion Valve One important characteristic of Leonardo Max is that the dehumidification is achieved without a reduction in the airflow rate. Direct expansion Leonardo units use an innovative system of dehumidification by means of the electronic expansion valve and Uniflair’s exclusive control software

Tandem Heat load can be extremely variable during working day and during one year

Tandem Units with **42 suffix are provided with 2 compressors in parallel in the same refrigerant circuit and are supposed to be used during part-load.

Tandem During part-load running, these versions increase their COP because exchange coils are dimensioned for full load power.
