OTE med cases both heat and cool to insure the correct temperature set point for both summer and winter. The temperature settings are user adjustable using the temperature control module. Aluminum is used to keep these units light weight, easy to maintain, and durable. The interior is FDA compliant that is easy to clean plastic and easy to see with LED lighting. Super high tech insulation reduces power consumption and allows the med units to maintain temperature even when power is off (for short durations). The units come standard with flange or strut channel mounts for easy installation, even upside down for those hard to fit installations. Our units only require a single 12 VDC connection and operate at 84 watts maximum, with 24 to 48 watts (2 - 4 amps) as the average power consumption. The OTE med units are easy to use and install in a variety of configurations, including retro-fit applications.
