Branca hfo Type MAC is the climatic unit designed for big air volumes up to 800 m3

Charged with low gwp refrigerants that enhances a lower energy consumption thanks to its post-heating circuit.


Here below could be found the advanced features of the close-control unit hfo type MAC:

  • A wide close-control range in presence of critical external environment conditions from -20 up to 40 C of temperature and 10 to 90 % of Relative humidity;
  • Product certificates CE for EU, UL and CSA for USA and Canada;
  • Modular air flow distribution system with tangential inlet diffusion to the walls mixed with fresh air with inlet speed lower than 0,15 m/s on workdesks;
  • Refrigerant circuit lamination with electronic modulation valves and cooled-water electronic recirculation pump;
  • Reverse osmosis for water treatment and purification to ensure the water supply of demineralized water at 0 F;
  • Special humidification system with heating elements activated under proportional band;
  • Indoor centrifugal fan with GreenTech technology and analog speed control approved by EU;
  • Prefiltration frontal or from air ducts G3-G4;
  • HMI Touch 7" and PLC for a user-friendly management, monitor and trend graphs, alarms diagnostics and statistics;
  • Remote support control;
  • Reading resolution of probes at 0,01C and 0,01%;
  • Alarms diagnostics and statistics;
  • Datalogging functions;
  • Normal/ECO operation mode with weekly programming;
  • User manual, guidelines for installation and diagnostics;
