holding plate refrigeration systems are as reliable as your land based 120v kitchen refrigerator, while using half the daily amps of other 12v refrigeration systems.  Utilizing the latest technology in variable speed compressor design, low amp 12v fan, over sized condensing coil, and holding plate with preset expansion valve.
COOLBLUE operates simply and efficiently, eliminating the complexity and excess power associated with water-cooled systems.  While other 12v systems require water cooling at temperatures above 90F, COOLBLUE operates at ambient temperatures up to 120F without a loss in system efficiency.  All Technautics modular refrigeration systems are built, pre-charged with 134a refrigerant, and pre-tested prior to shipping and are cruiser installable and serviceable without any special tools, gauges or refrigeration experience.
