General description
Air conditioners designed specifically to create "an ideal atmosphere" for electronic systems, by removing excess
heat and keeping humidity within the tolerance limits with the highest levels of reliability and safety.
SPECIFICATIONS
Structure
The cabinet is made with galvanized steel sandwich panels that are epoxy powder coated. The panels are
internally insulated with glass wool, to obtain fire insulation class A1 (in accordance with EN13501). This type of
panel allows good thermal and acoustic insulation. Air tightness is achieved with adhesive sealing strips placed all
around the edges of the panels. The uprights and infills are made of galvanized sheet-iron.
The front panel closing the electrical control panel can be opened by handle for easy inspection of the inside.
Access to all the refrigerant and electrical components of the unit is from the front of the machine only; this
solution makes it unnecessary to carry out any work from the side and eliminates the obligation to consider
“technical spaces” around the air conditioning units. All the front panels are fixed to the structure by ¼ turn
fasteners and can therefore be easily removed. All the materials forming the structure are recyclable and CFC-
free.
Finish
Orange peel.

FILTERS
The filters are of filtration class ISO Coarse 75% (G4) and designed to minimize head losses and to have a high
degree of filtration. The thickness of the filters can be 50 or 100 mm depending on the sizes or the set-ups. The
filters are removed from the front of the unit. High efficiency filters can be supplied on request.
Coils
Finned pack, copper tubes and aluminium fins, with corrugated profile and hydrophilic surface treatment.
A stainless steel condensation collection basin is installed at the base of the coil, complete with fitting for drain
and siphon.
Fans
Radial with reverse blades, with directly coupled 4-pole motor (AC), having thermal overload protection.
The flow of air into the fan is continuously controlled by a differential pressure switch that activates an alarm when
there is no air flow.
Electric post-heating
Banks of electric heaters, with heating elements with low surface temperature, made of stainless material. In the
event of overheating, a safety thermostat intervenes by stopping the power supply to the heaters and activating
an alarm.
Humidification
Immersed electrode humidifier supplied with mains water, controlled through microprocessor, for steam
production with continuous modulation.
Hydraulic circuit
Comprises a three-way modulating valve (with 0-10V servo motor); controls environmental conditions by adjusting
the water flow through the exchange coil.
Electrical control panel
The circuit includes:
- Main disconnect switch
- Fuses to protect the power circuits
- Fuses to protect the auxiliary circuits
- Automatic circuit breaker to protect the auxiliary and power circuits
- Fan contactors (AC)
- Contactors for heaters
- Contactors for humidifier
Microprocessor
To control the following functions:
- Ambient temperature
- Humidity
- Speed of the condensation fans
- Alarm signal on two levels
- Alarm log recording with "black box" function
- a Modbus RS485 serial port for reading and writing purposes
- a RJ45 port for IP communication, including a reading and writing Modbus TCP/IP, available as standard

CONFIGURED UNIT ACCESSORIES DESCRIPTION
BAC - Bacnet serial card
RS485 serial card for connection of the unit to an external supervisor via BACnet MS/TP protocol
This card is in addition to the RS485 serial connection with ModBus protocol present as standard.
GABB - Packaging in wooden crate
The unit is protected by a made-to-measure wooden crate. The accessory is mandatory if shipping by container is
required
