Chiller i42 VSD

INVERTER-DRIVEN CHILLERS VARIABLE SPEED DRIVE – REVERSE CYCLE FUNCTION
This marine chiller unit line provides the best of the existing technology: a brushless DC motor with an inverter that constantly controls the speed and power delivered by the compressor (Variable Speed Drive). R410A eco-friendly refrigerant. Two sizes available: 42.000 e 62.000 BTU/h with modular combination to obtain systems with higher cooling power

Comfort: The compressor continuously changes the frequency/running speed and consequently its cooling power. In this way, the chiller water loop temperature remains constant, regardless of the power drawn by the fan coils. This guarantees the maximum comfort – thanks to the temperature stability of air- and the best efficiency, adapting continuously the cooling power to the real need. As a result, the compressor will operate at maximum power to cool rapidly the rooms, but coming closer to the set temperature, it will reduce its power and consumption.

Reliability: “Brushless DC” compressors, together with variable capacity operation, eliminate the typical ON/OFF function of traditional systems. This allows a much longer lifetime for all the electrical and mechanical components.

Silence: Thanks to its function and its soundproofing cover, the compressor has minimal sound levels. This is appreciated especially during night operations.

NIGHT mode: It is possible to limit the maximum output power to a preselected value (factory 40%) by simply pressing a button. This means the possibility to limit the max current requested, with no risk to break down the shore power if weak and, in double genset applications, it is possible to use the small and quiet night generator.

Modular: A number of units can be combined together in order to obtain the maximum power needed: for example, to get 250.000 BTU/h as max power, it is enough to install 4 units of 62.000 BTU/h in parallel. The units will regulate automatically in order to guarantee always the pre-determined value temperature with the lowest energy consumption.
