Water-cooled Self-Pumped Cooling Units with Intelligent Temperature Control +
The ITC Digital Display in conjunction with a Holding Plate forms a cooling unit called ITC+, where the storing energy effect is amplified thanks to the wide range of eutectic plates available. The intelligent energy management system charges the holding plate when batteries are at high charge level (engine running or on-grid) and restitutes progressively the cold energy to reduce drain on batteries when used as single source of energy.
Self-pumping sea-water cooled units
The Isotherm SP units cool with the use of seawater. This method has the advantage that the heat exchange is made via a water cooled condenser. The water-cooled Isotherm SP operates consistently at an extremely high level of efficiency. Without fans or pumps to remove the heat generated by the condenser, the SP system consumes less battery power and is remarkably quiet.
The Isotherm SP unit uses the movements of the hull to draw heat down and out through a special fitting in the galley sink drain hose. The flow is completely free inside the draining hose, so each movement of the surrounding water produces a similar quantity of water level inside the hose, which results in pumping an equivalent amount of water in and out. By designing a special hull fitting containing a non restricting, fullflow spiral heat exchanger for cooling the heated refrigeration agent, an extremely efficient cooling system is created.
As the hull fitting is situated away from the boat’s center of gravity, the smallest movement of the hull or mast of sailing boat is sufficient to create a pumping action. This movement results in constant withdraw of warm water and intake of cold water which also prevents fouling.
The Isotherm Intelligent Temperature Control can be used with new SeCOP DC only and AC/DC modules to reduce battery consumption, control the speed of the compressor, and digitally set and monitor fridge or freezer temperatures. The external digital control give the user full control over fridge functions like ECO (economy) Mode or Overcooling Mode
For boaters who want to minimize battery consumption and maximize cooling performance, the new Isotherm Intelligent Temperature Control (ITC) takes advantage of new developments in DC and AC/DC control modules from SeCOP (Danfoss) to reduce energy consumption. The ITC kit consists of a display module with easy to adjust controls which allows the user to set operating parameters for temperature and compressor speed.
The Isotherm Intelligent Temperature Control display panel provides an instant reading of actual temperatures inside the fridge or freezer. Temperatures can be changed with a simple press of the up or down keys in either Celsius or Fahrenheit. Fault display and 3 battery protection levels provide additional user control. Manual activation of the ECO function assures minimum power consumption in this energy-saving mode which runs the compressor at the slowest speed.
The ITC provides standard smart features such as:
- Soft Start which allows for effective, safe start-up of the compressor
- Fast Cooling is achieved by running the compressor at maximum speed to lower temperatures as quickly as possible
- Over Cooling is activated by microprocessor to accumulate cold when there is a surplus of energy such as when the battery is in charge mode (engine running, solar panels charging) or when on AC for AC/DC modules
The ITC Digital Display controls the temperature in a refrigerator or freezer compartment from the exterior of a fridge/freezer cabinet. The display can be mounted flush or proud mount (see download below for details). Settings on the display panel include temperature setting, selection of energy saving options, choice of 3 battery protection levels, and compressor operating mode settings (ITC, ECO, and Overcooling modes).
The ITC works with both DC only modules and AC/DC modules, specifically the the new generation SeCOP control modules 101N0212 (DC only) and 101N510 (AC/DC) for BD35F / BD50F compressors. All new Isotherm fridges come equipped with the new generation SeCOP modules.
Indel Webasto Marine takes years of expertise in energy-saving innovation that began with ASU, then ISEC, and now the Intelligent Temperature Control to make a simple-to-install kit that will revolutionize energy savings for the boating industry.

Replace Your Sink Skin Fitting with the SP Condenser Skin Fitting
(Note: A SP Condenser Skin Fitting is Supplied with this fridge kit and your sink can still drain through the centre of it )
Summary:
Cooling energy stored in the holding plate (eutectic tank) maintains box temperature without the compressor running. The compressor runs at low speed for short periods to maintain stable box temperature.
We recommend to reduce the box volume by 10-20 %, in tropical conditions. Specification changes may be made without prior notice.
Other Options:
- SEH00004HA – AC/DC Converter Module to suit BD35F and BD50F. IN: AC 100-230V 47-63 Hz / Batt. 12-24VDC OUT: 25.5VDC 100W / 4.3A
Typical Boat Combined Fridge /Freezer Box (Not supplied)
