Isotherm 3251 SP refrigerator/freezer unit ITC+ with SP seawater cooling, holding plate and ITC control
The Isotherm ITC+ systems were developed for installation in existing cool boxes. They are primarily intended for use on sailing boats, where battery power is especially valuable. The ITC+ system provides maximum cooling performance with minimal load on the batteries. It detects when surplus energy is available from the boat engine's generator and increases the compressor speed so that the holding plate is cooled down quickly. When no surplus energy is available, the system reduces consumption accordingly. The stainless steel holding plate can be installed at any angle high up in the cool box before being connected to the compressor unit. Connection is made using 3 m long, 6 mm flexible copper pipes with quick couplings. The compressor unit is so small that it can be installed in a locker or another unused space within connection distance of the holding plate. After connecting the power cables to the battery, the pre-charged refrigeration system is ready for operation.
Third generation refrigeration compressor with refined ITC+ system. The new Danfoss compressor is not only more compact, but also significantly lighter and more efficient. In a system without ASU, the energy saving compared to older compressor types is up to 20%. With ITC+ and other refinements, energy consumption has been reduced by up to 50% compared to previous models. The compressor runs so quietly that we have now integrated a separate speed control for the fan, as this was more audible than the compressor. The new ITC+ system regulates the compressor and fan to the lowest possible speed when running only on battery power.
The ITC+ system is controlled using a special control panel. When switched to NORMAL/AUTO, this unique system operates in fully automatic mode, maintaining the correct temperature with the lowest battery load. When battery power is not being used – for example when connected to shore power or a solar panel – MAN-TEMP mode can be selected and the temperature can be adjusted manually using the rotary knob on the control panel. 12/24 Volt.
The practical "click-on" bracket for horizontal and vertical installation is included in the scope of delivery
Note: For the water connection, we recommend replacing an existing through-hull fitting with the one supplied. If there is not yet a through-hull fitting on board, a 1 1/4" ball valve, a hose tail and hose are required for the connection. These components are not included in the scope of delivery.
