Climatic unit type 0

Air climatic unit type 0 Branca Idealair allows to obtain and maintain the precision air conditioning inside a laboratory within desired limits for thermo-hygrometric conditions

• Temperature: 23 ± 1°C;
• Relative Humidity: (45 ÷ 50) ± 2 %;

or:

• Temperature: (20 ÷ 21) ± 1°C;
• Relative Humidity: 65 ± 2 %;

According to the technical specifications the air climatic unit type 0 can assure the proper air conditioning inside laboratories with volumes of (20 ÷ 50) m3.

FRAME

The structure of the climatic unit is realized with a stainless steel cabinet with wide front opening and comfortable doorknobs for the easy inspection of the refrigerating circuit and the electrical circuit for technical and servicing activities.

All air climatic units designed by Branca Idealair are equipped with a special vessel able to recover all condensed water generated by the phase transition of the air after crossing the evaporator.
The tank is additionally used for humidification heaters, that heat up water to get the humidity close-control (%).

The upper compartments of the unit include the electrical circuit and the user interface HMI TFT Touch Screen 7".

AIR FLOW DISTRIBUTION
An advanced technology for the Climatic Unit Type 0 allows to keep under laminar flow the air distribution in every point of the laboratory; the indoor unit is equipped with a centrifugal blower with automatic rotation speed control in compliance to EU Standards. With the progressive increment of accumulated dust on the air filters, the ultra-silent blower motor changes gradually speed ratio proportionally to the increase of air losses of the aeraulic circuit maintaining always the same air flow.

PRE-FILTRATION AND FINAL FILTRATION
Air suction filters at medium efficiency like G4 on unit suction are provided just before the air return ducts or inside the front panel of the Climatic Element to achieve the lowest level of air pollution inside the unit compartments and inside the laboratory too. The final filters type HEPA characterized by an high filtration efficiency in the air inlet like F6 assure the overall elimination of harmful bacterias for the human breathing apparatus inside the laboratory in accordance to national and international Work Safety Standards.

REFRIGERANT CIRCUIT

Most part of customers need a system that reduces both electrical power consumptions and expenses, but the air handling sysem needs always to guarantee the requested conditioning of ambient conditions according to the Reference Standard.

Branca Idealair studies solutions to achieve maximum performance with reduced energy consumption

Furthermore we create high-performance refrigerant circuits able to ensure desired conditions with low-energy consumption and charging only refrigerants compatible with the international Standards in compliance with protocols of Kyoto and Paris, thus charging only HFO freon gas with LGWP equal to 0.
Close control with electronic modulation valves avoiding any mechanical breakdown and reducing power consumption of 30% less, drier filters on LOW pressure circuit to prevent any possible cause of damage to the compressor, outdoor unit with air condenser fans controlling the stability on HIGH pressure circuit condensation, close-control on low temperature Dew-Point and compressor injection to keep chassis temperature under constant regulation.
Evaporator, composed of copper tubing and copper fins to prevent the redox with different conductors in presence of water greedy of ions.
Bactericidal action of the copper fins preventing bacteria in conditions of saturation.
Space between fins of 3 mm to allow a periodical servicing on the heat exchanger with a high pressure water pump at floor level;

WATER FEEDING SYSTEM
A special water ECO system without any regeneration cycles, but keeping under acceptable limits the water consumption by the Climatic Unit Type 0; moreover the system allows to feed the humidification vessel passing through a sequence of filters and reverse osmosis group; the pressure switches (safeties) cover all the circuit protected from limescale devices to avoid any risks of water flooding.

AIR FLOW DISTRIBUTION
With air speed less than 0,15 m/s to the work desks, tangential to the walls, with hot air recovery device with recirculation air collection from the top between insulated roof ceiling and false ceiling.
False ceiling in aluminium with heat absorbent action able to guarantee the maximum results in terms of uniformity for the samples to the work desks, and simultaneously energy save in compensation to the post-heating heat exchanger.
