Climatic unit type 0

Climatic unit Type 0 is a precision air conditioner ideal to ensure climate control for laboratories up to 50m3

EC Type 0 allows reaching and maintaining constant conditions required for samples conditioning and testing.

EC Type 0 maintains constant control of both temperature and relative humidity under the parameters listed below:

STRUCTURE

The frame is made of painted steel in the form of a floor-standing unit with wide, hinged panels designed to allow proper maintenance by the technician.

The unit allows easy access to the cooling circuit and the electrical components of the system.

Condensing water produced by the evaporator drains to the humidification basin.
This condensate pan contains humidification heaters to warm up the demineralized water produced through the reverse osmosis system.

It ensures a steady relative humidity close control.

The upper compartments contain electrical components and control devices such as HMI Touch Screen 7" and logic programmable unit.

VENTILATION
The advanced technology of Climatic unit Type 0 allows the air delivery under a laminar flow control and distributed uniformely throughout every point of the laboratory as a sea of conditioned air.
Type 0 provides ventilation by means of a centrifugal fan with automatic speed control.

As the filters cumulate dusts, the blower increases proportionally the rotation speed to compensate the air pressure losses and maintaining the same air flow capacity.

FILTRATION

Return air filters with medium efficiency and filtration class G4 (EN779).
The pre-filters are mounted on special filter frame holders provided in the front panel and return air ducts to reduce aerosol particulate in the laboratory.
Outlet air filters are mainly HEPA filters with filtration class F9 designed to remove at least 99,97% of particles larger than 0,3 microns from the air.
UVC germicidal lamps are capable of total disinfection against dusts and bacteria that could be harmful to human health.

REFRIGERATING CIRCUIT

Refrigerating cirucits by Branca Idealair are designed to ensure both high performance and low energy consumption in stand-by mode starting from the selection of the parts.

The circuit is charged only with sustainable and ECO-friendly refrigerants in accordance with the latest international rules, phasing out the use of HFC (Hydrofluorocarbon) such as R134A, R410A, R407C and using HFO refrigerants (hydrofluoroolefins) R513A with GWP 573 as protection against global warming and greenhouse effect.

The refrigerating circuit is equipped with electronic valves to exclude any wear of mechanical contacts with traditional solenoid valves.

Drier filter on compressor suction to prevent liquid backflow, external air condensers with fan rotation under constant control of condensation pressure, dew point temperature regulation and compressor injection to maintain temperature under constant control.

Evaporator consisting of copper tubes and fins to prevent the redox contact effect with other conductors in the presence of ion-rich water.

Bactericidal effect of copper lamellae to prevent bacteria under saturation conditions.

Spacing between fins of 3 mm for a perfect cleaning of the heat exchanger with a high-pressure water pump.

WATER CIRCUIT
An ECO-water feeding system that ensures water level control in the tray while also saving water consumption. The water is generated through the reverse osmosis, which ensures water treatment to obtain demineralized water at 0°F; the pressure switches (safety devices) cover the entire circuit, which is protected from presence of scale deposits to avoid any risk of water flooding.

AIR FLOW DISTRIBUTION
With an air velocity of less than 0.15 m/s to the work tables, tangential to the walls, with warm air recovery unit with recirculation collection from above between insulated roof ceiling and false ceiling.
Intermediate ceiling made of aluminium with heat absorbing effect that guarantees maximum results in terms of uniformity of the samples on the work tables, while allowing energy savings in the compensation of the post-heating heat exchanger.
