Air conditioning unit – CLIMA-HT


Specific conditioning units for clean rooms that require the maintenance of hygrometric conditions with restricted tolerances. The particular constructional features mean extreme simplicity of installation and maintenance, ensurig the complete inspection of the device from the front and the quick replacement of each component. The conditioning unit is controlled by a programmable microprocessor system to meet the particular needs of each clean room. The functions to control all the aeraulic, electric and refrigerator components, mean the unit is effectively an integrated system for the precise maintenance and monitoring of temperature, humidity, pressure, ventilation and air purity.


Product Description

Technical Data

Function Diagram

Microprocessor controls

Climate-HT series units are equipped with specific control
software developed on the basis of experience gained over the years in the production of Cleanrooms, to meet the needs of different industrial sectors. It is a truly integrated system that allows total control of all the Cleanroom parameters, including those typical of the air conditioner, such as:

  • Temperature
  • Humidity
  • Airflow
  • Ambient pressure
  • Clogged pre-filters and HEPA filters

The PLC is equipped with an interface that allows managing, via
Modbus, up to 100 Filter Fan Units (FFU) series AIR-1 and HT-AIR10-ML, normally used for room air circulation. Of each unit the
system monitors:

  • Start / Stop.
  • State / alarm.
  • Set operating point.
  • Class.
  • Operating mode (normal / reduced).

The application also allows you to:

  • Display the alarms detected in their acoustic signal by means of the buzzer;
  • The display of all set sizes;
  • The management of the data logger;
  • The remote control of all parameters via web interface to any user in charge of the Cleanroom controls./li>
