DURAN ELECTRONICA Système centralisé DURPARK

DURPARK CONTROL UNIT

An affordable electrochemical sensor-based CO and NO₂ detection system (in the same loop), with a maximum service life of 5 years (CO) and 3 years (NO₂), offering
a wide range of features.

Specially designed for the protection of underground car parks, workshops, garages and small facilities. Three-wire communication and adjustable.

Each detector is monitored individually, with its status displayed in real time on the screen. High reliability and accuracy of ±1 ppm (CO) and ±0.5 ppm (NO2). This control unit offers automatic zero and gain calibration using software algorithms, even allowing the sensitivity of the CO sensor to be checked without the need to apply gas.

It incorporates a special function allowing the detectors to be left in test mode.

It includes Spanish and Portuguese regulations in three languages.

Each zone features an LCD screen with independent operation.

It incorporates three potential-free relay switch outputs and therefore three independent programmable intervention levels per zone, plus a general fault output.

Dual-speed ventilation configuration.

Available in a MINI version with 16 detectors and an expandable version from 1 to 4 zones, and up to 64 detectors.

Complies with standard UNE 23.300:1984 according to Certificate No. LOM 14MOGA3084.

Certificates No. E20/000002 (DURPARK) and E20/000003 (DURPARK MINI) issued by the accredited inspection body AENOR ENAC RD. 2367/1985.

DURPARK CO AND NO2 DETECTORS

RS485 infrared detectors designed for the detection of explosive gases, CO2, N2O, SF6 and refrigerant gases, designed exclusively for connection to DURGAS control panels.

Addressable detectors with 4-wire connection. Local alarm relay output (standard for refrigerant gases and SF6, and optional for other gases) in the IP65 plastic version, and optional programmable alarm relay module for ATEX versions.

Specially designed for:

● Installations requiring detection of inhibitory or toxic gases using catalytic detectors (pellistors).

● In oxygen-free atmospheres.

● Refrigeration, livestock farming and intensive agricultural processes in general.

● Installations where maintenance operations must be kept to a minimum.

 

Unlike other technologies, with infrared detection, the presence of the gas to be detected does not reduce the sensor’s service life. DIREX is not affected by this phenomenon.

Available gases: Methane, Natural gas, Propane, CO₂, N₂O, SF₆ and refrigerant gases.

Available in IP65 plastic (DIREX) and ATEX explosion-proof (DIREX-X) versions with ATEX certification LOM08ATEX2059 X.

Detection range: 0 to 100% LEL (explosives), 0 to 2% vol (CO2), 0–1000 ppm (N2O), 0–2000 ppm (refrigerant gases and SF6 in the plastic version) and 0–100% LFL (refrigerant gases in the ATEX version).

Visual fault indicators on the loop and the sensor.

Factory-calibrated with calibration gas: no additional calibration is required during installation.

Also available in 4-20 mA format (except for refrigerant gases and SF6).
