UB is the line of self contained direct expansion and sea water condensed marine air conditioners, ideal for cooling/heating one or more contiguous cabins into small/medium vessels (8-18 m). UB’s are available in 7 sizes, from 7,000 up tp 24,000 BTU/h cooling power, in cooling only version, heat pump version with reverse cycle and also equipped with electric heater. UB series has an extremely light and compact design for easy installation and service. All components (high efficiency and noiseless compressors and blowers, corrosion resistant copper-nickel condenser, high and low pressure switches) are assembled on a 100% stainless steel case which assures a long life service and the collection of great quantity of condensate.
For an immediate use, these air conditioners are equipped with a LCD back-lighted digital control panel and a practical infra-red remote controller, both supplied as standard components. The electronic controller has a highly innovative PC board which manages all the functions of the air conditioner (temperature setting, fan speed, operation mode…) as well as the failures diagnostics through well-defined alarm codes.
The best quality of the treated air is assured by the installation of an easily removable and washable filter. Each unit is pre-charged, leak checked and tested in all operating modes at the most critical conditions. All Thermowell marine air conditioners are filled up with environmentally friend green refrigerant R410A and no further charge is required before the installation on board.
