Category: Honeywell

Description

Technical Specifications:

Supply Voltage: 24 VDC (Range 12–29 VDC)
Power Consumption: 9.5 W per fan (Total ~19W)
Airflow: 360 m³/h (211.8 CFM)
Speed: 3200 RPM (±10%)
Noise Level: 52 dB at 1m
Feedback: NO dry contact alarm (Max 0.5 A / 240 VAC)

Functional Features: Provides cabinet thermal management; built-in tachometer generates a fault signal if speed drops below 1500 RPM; triggers system alarm via DCS/SIS.

Performance Parameters:
Life Expectancy: 85,000 hours at 40°C; 37,500 hours at 75°C
MTBF: >250,000 hours (Telcordia SR-332)
Operating Temperature: -30°C to +75°C

Material Composition: Metal mounting panel; dual Papst ball-bearing fans; integrated detection PCB.

Structural Characteristics: Dimensions 391 × 142 × 51 mm; weight 1.7 kg; IP20 rated; panel mount design for standard rack cutouts.

Working Principle: Dual fans operate in parallel to create positive pressure airflow, expelling heat from electronic modules; rotational speed is monitored by hardware comparator circuits sending status to the control system.

Advantages Highlights: Redundant airflow design; fail-safe alarm feedback; long-life ball bearings; direct compatibility with Honeywell FC racks.

Applicable Industries: Petrochemical, Power Plants, Offshore Platforms, Pharmaceutical Manufacturing (any controlled cabinet environment).

Model Series: Honeywell FC-Series Cabinet Accessories / FDSI Cooling Units.

Installation Requirements: Secure to cabinet top/rear panel using provided mounts; connect 24 VDC power to terminal block; route alarm contacts to spare DI point.

Usage Precautions: Ensure unobstructed air intake/exhaust paths; verify alarm contact wiring polarity; do not operate outside -30°C to +75°C range; replace as preventive maintenance after 5 years continuous operation.
