CTM CT-25H Marine AC FAQ
How much does CTM CT-25H weigh?
CTM CT-25H weighs exactly 85 lbs net weight. This heavy-duty self-contained marine air conditioner delivers 25,000 BTU of high-capacity cooling performance, utilizing single-phase 230 Volt electrical distribution lines to regulate large multi-cabin layouts efficiently without shifting the necessary running ballasts of fast vessels.
What duct size does this unit need?
CTM CT-25H requires a 7 inch duct ring size. This oversized diameter metric lets your high-velocity rotatable turbo blower push massive air volume freely, eliminating static friction stress inside extensive ventilation networks and ensuring balanced environmental thermal reduction across spacious boat deck cabins.
Where should you install CTM CT-25H?
CTM CT-25H is perfect for large master suites and open main salons. Marine rigging yards typically bolt this standalone system down inside deep cockpit lockers or beneath main lounge benches on motor yachts up to fifty-five feet, where its titanium water coil provides superior long-term reliability.
