Product Description:
The HPC-K55A-2 Cabinet Cooler is engineered by Okuma for cooling enclosed electrical cabinets. It is designed to manage thermal loads efficiently. The model provides stable cabinet temperatures in demanding industrial settings.
The HPC-K55A-2 cabinet cooler operates on a 2 phase 200 V supply with a 50/60 Hz frequency. The cooler draws 0.64 A at 50 Hz and 0.58 A at 60 Hz. The cooling method of the model is based on forced air via a heat exchange system. It uses air to air cooling where internal heat is transferred externally using airflow without introducing outside air into the enclosure. The unit achieves a heat exchange rate of 550 watts at a 10 °C temperature difference (ΔT). This makes it suitable for cabinets where internal electronics must be kept within specific temperature ranges. On the front panel, there are two axial fans mounted in the top section to enhance air movement and heat transfer. At the rear, ventilation louvers are positioned at the bottom to support airflow and assist in heat dissipation. There is also a small switch or connection port near the lower rear section for user access. The electrical setup of the cooler aligns with global industrial standards. It maintains stable current draw across both supported frequencies. The configuration is compatible with automation and control equipment where efficient thermal performance is essential.
The HPC-K55A-2 cabinet cooler from the HPC series features a flat back design with visible screw holes for easy surface mounting. The housing is constructed primarily from sheet metal. The flat back design simplifies alignment during installation and ensures a stable fit against enclosure panels. The fan system combined with the strategic placement of louvers delivers a controlled internal environment without exposing components to dust or contaminants.
Frequently Asked Questions about HPC-K55A-2:
Q: Does the HPC-K55A-2 maintain consistent cooling under dual frequency operation?
A: Yes, the HPC-K55A-2 cabinet cooler supports both 50 Hz and 60 Hz operation. It draws a steady 0.64 A at 50 Hz and 0.58 A at 60 Hz.
Q: How does the HPC-K55A-2 cabinet cooler handle heat without external air contamination?
A: It uses a sealed air to air heat exchange system. Internal heat is transferred externally using forced airflow without introducing unfiltered outside air.
Q: Can the HPC-K55A-2 Cabinet Cooler be mounted securely on flat surfaces?
A: Yes, the HPC-K55A-2 from the HPC series has a flat back with visible screw holes. This ensures precise alignment and solid contact during panel mounting.
Q: Is the HPC-K55A-2 suitable for enclosures with sensitive electronic components?
A: Yes, it provides 550 watts of heat transfer at a 10 °C temperature difference. This performance keeps internal temperatures stable in high load electronic cabinets.
Q: How does the airflow mechanism of the HPC-K55A-2 optimize cooling performance?
A: It includes two axial fans at the top front panel for active air movement. Ventilation louvers at the rear bottom enhance airflow and support heat dissipation.
