CTM Marine CT-6S 6000 BTU Soft Start Boat A/C

Description

Boats using small generators, inverter-backed power, or lithium battery banks can benefit from reduced compressor startup demand in a compact cabin system. The CTM Marine CT-6S 115V provides 6,000 BTU/h of cooling and 6,000 BTU/h of reverse-cycle heating. Its integrated soft-start microcontroller is intended for compact staterooms, cuddy sleeper cabins, and small boats from 16 to 26 feet.

Key Features of CTM CT-6S

This 115V soft-start marine heat pump combines compact cabin capacity, reduced listed startup current, touchscreen controls, and a rotatable four-inch blower collar for flexible installation.

• Provides 6,000 BTU/h cooling for compact staterooms and cuddy cabins.
• Adds reverse-cycle heating for cooler overnight conditions aboard smaller boats.
• Uses integrated soft start with a listed 8.5 A startup rating.
• Operates on compatible 115V, 60 Hz, single-phase marine power.
• Uses a rotatable four-inch collar for flexible duct placement.
• Supports touchscreen control through a multi-system interface board.

Application and Installation Notes

The CT-6S is intended for inverter-backed compact staterooms, pocket cruisers, cuddy sleeper cabins, and 16 to 26-foot boats using micro-generators or lithium battery banks. Confirm the 115V supply, 15 A breaker, 180 GPH seawater loop, four-inch ducting, touchscreen location, condensate route, and service clearance. The corrosion-resistant stainless steel pan supports installation in compact equipment spaces.

Who This Unit Is Not Ideal For

This model is not intended for 230V-only boats, large cabins, or applications requiring more than 6,000 BTU/h. Final system planning should also verify that the inverter, generator, battery bank, and wiring are appropriate for the complete onboard load.
