Eco Cooler Kit to convert the ice-box in fridge


BallEasy installation, a sea-cock to water load and a sink-drain to water outflow ;
BallNo maintenance, because it doesn’t use gas and moving power parts;
BallIt doesn't sacrifice valuable spaces, because it doesn’t use compressors and condensers;
BallIt doesn't add heat on board, because the heat is dissipated by the sea-water;

Please watch this video about the typical installation and test by "Sailing UMA"

From many years people tried to use thermoelectric modules for the realization of small fridges. Unfortunately up to now the results has been unsatisfactory… high consumptions or insufficient thermal gradients.

ATEN - Italy, specialized since 1978 in the development and production of electronics devices and high-tech systems, thanks to the development of an innovative electro-mechanical device controlled by advanced firmware, it has gotten from new thermoelectric modules a consumption / refrigeration ratio ever reached until today. So KECO was born, the refrigerant Kit destined to iceboxes or insulated lockers thermo-controlled by sea water.
The design is smart enough to guarantee the electric and water safety considered the specific destination to recreation sail-motor boats. Being it destined to the food and drink refrigeration (but not for the ice making) it uses high quality components and materials as anodized aluminum, stainless steel, nylon, neoprene and other non-toxic components carefully selected. It's very space-saving and it ask only the availability of a sea-cock and a water discharge.

Technical characteristics and functions
Ball Dimensions / weight:
       - Control Unit (plastic box): 70 x 125 x 40 mm. / 180 gr.;
       - Cooling Plate: - Radiator (anodized aluminum and stainless steel): 122 x 200 x 35 mm.;
                              - Heat-sink (to built-in) with dimensions: 50 x 110 x 40 mm (tube holders excluded);
                                Total weight 900 gr.
Ball Power supply: - 10.5 – 14.5 Vdc.
Ball Power Consumption (with standard mini-pump): < 32 Watt - low-operating in Normal mode;
Ball Current Absorption (with standard mini-pump @ 12,5 V):
        - Normal mode (low power): < 2.6 A. or < 1.7 A. (average) if working in Stand-by mode*);
        - Burst mode (high power): < 9.5 A. for 5 minutes or less if reached the Stand-by mode*);
        - Cycle mode (middle power 20 seconds Burst + 120 seconds Normal): < 5 A o less if in Stand-by mode*).
Ball Maximum Delta-t: up to 27 C (81 F) (on typical ice-box) between the sea-water and radiator temperature.
Ball Electrics protections: - auto-switch-off for power supply = 10,5 V. **).
Ball Thermal Protections:
        - Auto-switch-off for high temperature on heat-sink = 40 C ***);
         -Stand-by mode for low temperature 0 ÷ 1 C (32 ÷ 34 F) to avoid the ice on the radiator.
Ball Water mini-pump (standard):
        - Dimensions / weight: 55 x 45 x 55 mm / 200 gr.;
        - prevalence 2 m (not sucking);
        - noisiness 17 dB, consumption 0.6 A;
        - ceramic bearing replaceable, life expectancy = 50,000 hrs of operation.
Ball Water pump (special):
        - Dimensions / weight: 75 x 55 x 66 mm / 400 gr.;
        - prevalence 4 m (not sucking);
        - noisiness 24.5 dB, consumption 1.6 A;
        - ceramic bearing replaceable, life expectancy = 50,000 hrs of operation.
Ball Water tube collectors: - 10/13 mm.
Ball Electrics cables (not supplied on kit):
        - Main power supply (from magneto-thermal switch 15 A.): 2 x 2.5 mm (AWG-11);
        - Refrigerator Power supply: 2 x 2.5 mm + 2 x 2.0 mm (AWG-12), 2 meter max;
        - Sensors and mini-pump: 3 x 1.0 mm + 2 x 1.0 mm (AWG-18), 2 meter max.
Point

Notes:
*) reached the temperature 0 C on the radiator and up to the auto-restart (Stand-by mode for 20 seconds) the total absorption decreases under 0,6 Ampere. In this condition is operative only the mini-pump for the water circulation.

**) The device go in switch-off automatically when the battery voltage decreases under 10.5 Volt for over 5 seconds.

***) The device go in switch-off automatically when the temperature of the heat-sink reaches 40 C (104 F) , i.e. due to the block of the water circulation.

Kit standard composition:
- Microprocessor Control Unit;
- Cooling Plate with two set of nylon tube holders 10/13 mm. (two straight and two at 90°);
- Mini-Pump, with nylon pipe collectors 10/13 mm, and amortized mounting brackets.
