51400764-100 | Honeywell | TDC 3000 / HVAC Dual Fan Module Assembly

Product Overview

The Honeywell 51400764-100 functions as a high-performance Dual Fan Module built to provide critical ventilation, forced-air cooling, and thermal regulation for industrial control racks, DCS cabinets, and commercial HVAC infrastructure. This dual-rotor hardware assembly installs directly into dedicated 5-slot chassis setups to continuously draw stagnant heat away from dense electronic components. We distribute this component exclusively in 100% brand new, original factory condition to ensure exact bearing alignment, low mechanical noise thresholds, and uninterrupted heat dissipation.

Technical Specifications

Engineering Advantages

• Saves Premium Control Cabinet Space: The ultra-compact 16.3 cm x 8.2 cm x 4.1 cm footprint slips directly into constrained 5-slot chassis channels, allowing engineers to add high-volume ventilation without altering surrounding wiring trays or expanding the cabinet shell.

• Withstands Severe Thermal Spikes: The heavy-duty stainless steel diaphragm design and specialized motor bearings operate across a broad temperature scale from -40°C up to +85°C, preventing rotor lockup in unconditioned desert locations or high-heat boiler rooms.

• Suppresses Inductive Electrical Noise: The internal motor drive board limits electrical noise emissions to less than 0.1% of full scale. This suppression stops electromagnetic interference (EMI) from leaking into adjacent multi-channel analog input cards or sensitive communication lines.

• Maintains Stable Calibration Vectors: The precision assembly structure delivers an airflow accuracy of ±0.25% of full scale, providing predictable, balanced linear air velocities that eliminate variable hot spots inside the component nest.

FAQs

• Can I run this cooling module directly from an un-stabilized 120V AC source?

  No. The 51400764-100 fan module utilizes an internal brushless motor configured strictly for a 24V DC input voltage supply. Connecting this unit to a high-voltage AC grid will destroy the internal logic boards and melt the stator windings instantly.

• Is this an authentic Honeywell product or a generic aftermarket cooling frame?

  We distribute this item exclusively as a 100% brand new, authentic factory-original piece. It retains all manufacturer tracking barcodes, anti-static protective boxing, and original quality control stamps.

• What installation rules prevent early bearing failures?

  Mount the module completely flush into the 5-slot guide rails using the pre-drilled frame points to eliminate chassis resonance. Clear all stray cable ties, wires, and insulation dust from the intake zone before powering the 24V DC line to prevent foreign object ingestion.
