Procurement Notes

Verify the specific voltage rating (230V) and frequency (50/60Hz) compatibility with your power supply before procurement. Confirm that the physical dimensions (29.5H x 15.75W x 8.63D) fit the target enclosure space. Ensure the unit selected matches the required cooling capacity of 4,000 BTU for the specific heat load. Check for any mounting requirements associated with side-mounting configurations.

Selection Notes

Select this model when high corrosion resistance is required due to its SS304 construction. It is suitable for applications demanding Type 4X environmental protection. Consider the 4,000 BTU capacity relative to the internal heat generation of the enclosure. Verify that the 230V power input aligns with available facility infrastructure. Evaluate the operating temperature range limits against expected ambient conditions.
