CTM has taken nearly a decade of experience as a top-selling marine A/C retailer in the US, and combining this with an understanding of the wants and needs of marine A/C customers — as well as where other major brands could be improved — CTM has created a self-contained marine air conditioner that raises the bar on quality and performance.
And while lightweight and with a small footprint, the CTM CT includes titanium circulating coils, a high-velocity rotatable turbo blower (rotates less than 250 degrees), stainless steel bolts, and a stainless steel structural pan with Plastic ABS tray in order to ensure long-lasting, corrosion-proof performance in even the toughest of marine environments.
All CTM Control Boards, Temperature Sensors, and cables are made in the United States under strict quality standards. Every CTM Unit comes with an industry-standard 2-year warranty*, knowledgeable and attentive customer service, and ships ground to you free of charge within the US.
As marine A/C retailers, as well as boaters ourselves, we know what boaters are looking for in a marine A/C system — and this is exactly what the CTM line delivers. Any questions on setting up the 12V Marine Air Conditioner, just contact us.

Compatible with Most Thermostats
Because the CTM unit comes with the Universal Control board, it should work with the controller you currently have. Supported controllers include the SMXir, Passport I/O, Smart Touch, and Elite II. However, there are some older versions of the SMXir and Passport i/o controllers that don't have the firmware to work with the new universal board.
