2.1. GENERAL CHARACTERISTICS

The units are designed for indoor installation.

The constructive solutions and the internal lay-out allow high application exibility and the frontal access to

the main components for the inspection and routine maintenance.

The units require the refrigerant gas charge and electrical and hydraulic connections.

The end-of-line test consists of a functional test with reading and monitoring of operating parameters, alarm

simulation and visual examination.

2. PRODUCT

CHARACTERISTICS

The series is especially suitable for the installation in laboratories, archives, museums, and for tobacco,

textile and pharmaceutical processing plants where the parameters of temperature and humidity inuences

measurement, test and stockage of sensitive goods.

The combination of modulating hot gas reheating, modulation of cooling capacity by the inverter compressor,

and accurate and continuous adjustment of steam production, the unit ensures precise temperature and

humidity control (± 0.3 °C and ± 2 % RH).

In order to achieve this extraordinary performance, several important conditions are required:

• Heat load must be constant or stable, with variations no greater than 25% per hour

• The unit must be properly installed and ducted

• The space needs to be suitably insulated against outside loads (especially doors, windows, etc.)

• The conditions of the intake air are covered in the paragraph on "Operating limits".

NOTE:

The immersed electrode humidier periodically activates ushing cycles to reduce the salt concentration of

the water. During this short period of time, the humidier cannot guarantee the humidication functions so it

is possible that the humidity control exceeds the set point.

OPTIONAL ACCESSORIES

There is a complete range of accessories for adapting the unit effectively to the real needs of the system,

reducing the time and cost of installation.

2.2. INSTALLATION

• EER up to 4.88 at partial load

• BLDC inverter compressor for each refrigerant circuit to ensure the ultimate in energy eciency

• New Plug Fan with EC electric motor for lower power consumption

• Maintenance-free fan motor

• Continuous modulation of air ow and cooling capacity

• Dedicated control software for applications where extremely precise adjustment is required

• Single refrigerant circuit
