Grada RVP-P Rectangular Variable Air Volume Controller

Rectangular control valve vav

• VAV ensures volume flow control regulation by a given set-point. Set-point can be given as air volume flow or overpressure/underpressure.
• Parametrization is carried out in the factory in accordance with clients request. Advantages of variable air volume dampers are high regulation precision and no maintainance required.

DESCRIZIONE

• VAV dampers are used to control a variable or constant airflow volume in duct ventilation systems.
• All VAV dampers are equipped with a compact VAV actuator, which has an in-built pressure differential sensor and PID logic control.
• The actuator sensor is connected with rubber hoses to the measuring cross, which is used for measuring the duct airflow. By having real-time information about the volume airflow in the duct, VAVs can dynamically respond to the changes in the setpoint (temperature, C02 or humidity) and ensure optimized ventilation with the lowest possible energy consumption.

MATERIALI

• Casing e damper blade of the VAV damper are produced out of galvanized steel sheet. Sealing gaskets are produced out of EPDM rubber, and measuring cross is made out of aluminium tubes.

TESTS AND CERTIFICATES

• All our dampers are submitted to a number of tests by offi- Cial test institutes. Reports of these tests form the basis for the approvals of our dampers. Klimaoprema VAV dampers are also suitable for installation in buildings with high hygienic demands such as hospitals, clinics and pharmaceutical areas.
• To confirm this, out products are tested by an independent Institute of Hygiene, based in Gelsenkirchen, Ruhr, and comply with directives and guidelines in VDI 6022.

MANUTENZIONE

TRASPORTO

• After arrival, check the VAV dampper danni e carenze dovuti al trasporto. In caso di danni o carenze, contattare immediatamente il fornitore.

MAGAZZINAGGIO

• Se il damper non viene installato immediatamente:
• Rimuovere qualsiasi involucro.
• Proteggere il fuoco damper from dust and contamination.
• Do not expose the VAV damper to the effects of weather – store the damper in un luogo asciutto.
• Do not store the unit below -20 oc or above 50 oc.

Please properly dispose of packaging material!

MANUTENZIONE E FUNZIONAMENTO
Klimaoprema VAV dampers are designed with a fully enclosed drive mechanism outside of the duct and as such, do not require cleaning and regular maintenance.
However, the activation mechanism should be inspected for proper operation on a regular basis.

• Fornire almeno un controllo annuale del damper
• After each intervention, provide a systematic cleaning of dust and especially the solenoid and its movable plate
• Controllare che i terminali elettrici siano serrati
• Istruzioni per la pulizia: pulire con una spugna, con acqua o un detergente delicato
• Disinfection instruction: spray disinfectant (disinfectant may contain flammable alcohol; take precautions to avoid ignition)

Non è consentito modificare il dampers in any way nor perform any changes to their structure (except for the service procedures described in this manual) without the manufacturer’s consent.
Fornire almeno un controllo annuale del damper. The functional test must be carried out in compliance with the basic maintenance principles of the European norms EN 13306, EN 15423 and ENI 5650.

MESSA IN SERVIZIO

• Carefully unpack RVP-P – be careful of sharp edges and do not use excessive force for unpacking
• Inspect the product – check the volume flow damper per danni
• Installation of the volume flow damper – according to the installation instructions
• Before commissioning: check the product functions

FUNZIONI

• Electric actuator: Signal testing – the dampla lama deve chiudersi/aprirsi
