Royal cooling Fan TR655D-TP or TR655DTP

TR655D-TP | Royal Fan 200V AC Cooling Fan — 29W / 172×150×55mm / All-Metal / High Temperature / Industrial Inverter Cooling

Royal Fan TR655D-TP — All-Metal Industrial Cooling at 200V

The TR655D-TP is a Royal Fan (Japanese manufacture) 200V AC axial cooling fan rated at 29W — a high-temperature-resistant, all-metal construction cooling unit for industrial electronics enclosures. Royal Fan is a well-established Japanese manufacturer of industrial cooling fans, producing units specifically designed for the demanding thermal environments of industrial drives, inverters, and CNC equipment.

The 200V AC supply voltage (50/60Hz) places the TR655D-TP directly in the Japanese and international industrial supply class — operable from standard single-phase 200V industrial power without a transformer. The all-metal housing construction provides superior resistance to the elevated temperatures encountered adjacent to power electronics and inside drive cabinets.

Key Specifications

All-Metal Construction — Designed for Industrial Heat Environments

The all-metal designation distinguishes TR655D-TP from standard plastic-bodied cooling fans:

Metal housing and blade assembly: The fan housing, blade, and internal structural components use metal rather than polymer construction. Metal components retain dimensional stability at elevated temperatures that would cause plastic components to warp, deform, or embrittle — critical for a fan installed inside a drive cabinet where ambient temperatures can reach 40–60°C continuously.

High temperature resistance: Industrial inverters and drives generate substantial heat during operation. The TR655D-TP's all-metal construction tolerates the elevated operating temperature inside drive cabinets — both the steady-state operating temperature and the transient peaks during high-load cycles.

Mechanical durability: Metal construction provides superior mechanical resistance to vibration-induced fatigue compared to plastic — relevant in industrial machinery environments where continuous vibration from motors, pumps, and structural sources is the norm

Applications

Industrial variable frequency drives (VFDs): Cooling fan replacement in industrial drive enclosures — TR655D-TP provides the forced air cooling that removes heat from IGBT power modules, DC bus capacitors, and control electronics inside the drive housing.

CNC drive cabinets: Cooling for FANUC, Mitsubishi, Siemens, and other CNC servo and spindle drive cabinets — where the TR655D-TP exhausts heat from the drive compartment to maintain safe operating temperatures.

Industrial inverter cooling: Cooling fan replacement in VFD housings, soft starters, and uninterruptible power supply (UPS) units — maintaining internal temperatures within the drive manufacturer's rated operating range.

Industrial control panel cooling: Panel-mount installation in control enclosures housing PLCs, power supplies, and other heat-generating industrial electronics — preventing overtemperature shutdown and extending component life.

FAQ

Q1: What determines when TR655D-TP cooling fan needs replacement in an industrial drive?

Bearing noise (grinding, squealing, or rattling) is the primary indicator — fan bearings fail gradually, with increasing noise before complete failure. Reduced airflow (confirmed by checking the airflow with a hand or anemometer) indicates worn bearings or blade fouling. Many drives also have thermal protection — overtemperature faults that persist despite correct ambient conditions suggest the cooling fan is no longer providing adequate airflow.

Q2: Can TR655D-TP be connected to 220V or 230V single-phase supply?

TR655D-TP is rated for 200V AC 50/60Hz. Direct connection to 220V or 230V AC will result in the fan operating at approximately 10–15% above its rated voltage, causing increased current draw, higher motor temperature, reduced bearing life, and potential premature failure. For 220/230V installations, verify from the Royal Fan specification whether the TR655D-TP's rated voltage range accommodates the supply voltage, or select a compatible 220V-rated variant.

Q3: What is the correct procedure for replacing TR655D-TP in an inverter or drive cabinet?

Power down the drive completely and confirm the DC bus has discharged below 50V before opening the cabinet. Disconnect the 2-wire fan supply wires, noting polarity if applicable. Remove the mounting screws, replace the fan, and reconnect. Confirm the replacement fan rotates in the same direction as the original — reversed airflow exhausts heat into the enclosure rather than extracting it, increasing internal temperature.

Q4: What is the typical service life of TR655D-TP, and does ambient temperature affect it?

Industrial ball-bearing cooling fans typically have rated service lives in the range of 20,000–40,000 hours at rated voltage and temperature. Higher ambient temperature accelerates bearing lubricant breakdown and shortens service life. Royal Fan's TR655D-TP all-metal construction mitigates some temperature effects, but continuous operation at the upper end of the rated temperature range still reduces bearing life compared to operation at lower temperatures. Scheduled replacement during planned maintenance shutdowns prevents unplanned production downtime from fan failure.
