Inverter technology allows the refrigeration unit to understand the actual cooling capacity requirement. The machine, through sophisticated algorithms, calculates the optimal operating point at various working conditions and adjusts the compressor’s rotation speed in order to optimise efficiency and cooling output. The aim of the unit will always be to work at the lowest possible speed in order to limit pressure and work at higher COP.

The electronic valve provides the best possible control of the evaporation pressure. The step-by-step control regulates the refrigerant flow rate at the evaporator inlet, ensuring the correct supply of refrigerant according to the various operating conditions. The exchange surface will always yield the maximum possible cooling capacity.

The condensers are equipped with permanent magnet fans with 0-10 control. This type of fan, the electronic board and the machine’s control logic make it possible to best control the condensing pressure to maximise the machine’s total COP while reducing the electrical power absorbed by the fan to the indispensable minimum.

Machine condensers are sized to work with a temperature difference of 10K at nominal conditions. This allows the machine to work with a lower pressure ratio and therefore higher efficiency. Such sizing also means that the unit can work at a higher ambient temperature while remaining completely safe.

The new PRO family monoblocks are controlled by a new, state-of-the-art electronic board. The electronic board, through sophisticated algorithms, can manage the inverter, valves and fans in order to guarantee the COP of the machine and is able to make available to the operator a lot of useful information on the operation and programming of the machine.  

The exchanger pipes are internally rifled. This makes it possible to increase the exchange surface between the refrigerant and the inner wall of the pipe, improving exchange efficiency and reducing the dimensions of the coils for the same heat output. An exchanger with a grooved pipe can improve exchange efficiency by up to 25% compared to traditional smooth pipes.

Water condensation involves a brazed welded exchanger and a flow control valve. Water-cooled means that the condensing pressure of the machine will be be limited and it will work at more favourable and constant operating conditions over time.

This type of painting used on evaporators is particularly suitable for use in aggressive environments.
