If you're looking for the ultimate cooling power in a modular/custom refrigeration system, this is the way to go.
• Active water cooling provides the most efficient heat removal available. (Much more effective than traditional air cooling.)
• A cold plate evaporator offers the greatest reserves for continued cooling of your stored food when the refigerator isn't running.
(Much more cooling capacity than a simple low-volume sheet-style evaporator plate.)
• Option to be used in a refrigerator box or a freezer box
• Modular design offers many installation options
• Retrofit in existing built-in freezer or refrigerator compartments; or install in new construction
Isotherm Magnum refrigeration units are designed for vessels with exceptionally high refrigeration requirements – such as vessels sailing in tropical climates.
They combine ultra-efficient water cooling with high-capacity holding plates and sophisticated electronic energy management circuitry.
These units are ideal for installation in existing cold boxes, mainly in sailing yachts where battery power is at a premium.
The Intelligent Temperature Control microprocessor dramatically reduces power consumption while supplying refrigeration in abundance.
All Magnum refrigeration models have an integral seawater pump to circulate cooling water through the compressor, thereby greatly increasing cooling efficiency compared to air-cooled units.
The pump is quiet, self-priming, withstands dry running and is self-aerating.
The highly efficient compressor heat exchanger is manufactured of a corrosion-resistant copper-nickel alloy and fitted with a zinc anode.
These seawater cooled units are extremely efficient and offer increased cooling capacity.
The included remotely mounted ITC Digital Display in conjunction with a Holding Plate forms a cooling unit called ITC+,
where the intelligent energy management system charges the holding plate when batteries are at high charge level (engine running or on-grid) and gradually releases the cold energy to reduce drain on the batteries.
ITC - Intelligent Temperature Control Remote Digital Display features –
• Clearly displays and regulates the temperature within the refrigerated compartment
• Soft Start (always on) for effective, safe start-up of the compressor
• Fast Cooling (in user selected ITC mode) to lower the temperature as quickly as possible
• Over Cooling (user selected) to accumulate cold when there is a surplus of energy, for example with the boat's engine on, to use it when power is only coming from the battery
ITC Display Functions –
• Turns unit on and off
• Displays the actual temperature inside the refrigerated compartment
• Displays and/or changes the set temperature with a simple press of the up and down keys
• Selection of permanent energy savings operation
• Displays any operating faults
• Soft Start function - compressor revolutions are kept to a minimum for 30 seconds whenever the compressor starts allowing internal gas pressures to balance, and to prevent potential channel blockages
• Depending on system status, selects an energy-saving configuration or increased cooling power when adequate energy is available
• Selection and monitoring of temperature within a wide range from refrigeration to freezer
• Selection of temperature dispaly in Celsius or Fahrenheit
• Selection of maximum level of performance or energy saving
• Selection of 3 different battery protection levels and compatible compressor operation
Options at time of purchase:
Use as a freezer - requires non-standard Accessory Thermostat Cable
Dual Voltage Kit - use with 115/230V AC - requires non-standard Electrical Unit
The ITC circuitry senses when abundant power is available from the engine alternator, or even a solar panel installation, and speeds up the compressor to rapidly freeze the holding plate.
When the engine is off and the compressor is running on battery power alone, the ITC circuitry "sips" power by only running intermittantly for short periods -
just enough to maintain the box temperature, without attempting to freeze the cold plate further.
With normal engine operation, the result is a significant 30 to 50% reduction in electrical consumption from your batteries!
These units can provide refrigerator or freezer capability with temperatures down to as low as 21°F (-7°C).
• Holding plate can be fitted at any suitable angle high up in the box
• Compressor is small enough to be fitted in stowage compartments within connecting distance from the holding plate
• Water-cooled, self-pumping models include a bronze thru-hull with integral connection fittings and utilize slight motions of the boat to circulate the cooling water
• Extremely quiet operation
• Controlled by special control panel
• Ice cube tray available
• Pre-charged and ready to go
• Easy installation; compressor snaps into pre-mounted base bracket
• Can be mounted on horizontal or vertical surfaces
• Runs on 12V or 24V DC
• An optional Universal AC/DC kit is available for 12/24V DC and 115/230V AC at 50/60Hz is available
Electrical Power Sources
Indel's Isotherm refrigerators feature Secop (formerly Danfoss) compressor units, which come equipped with an electronic control module on the side. These modules are rated for either a DC Only power source, or for AC/DC power sources.
DC Only modules (101N0212) run on nominal 12 or 24 volts and have red and black wire leads which connect to the positive and negative terminals of your boat's batteries.
A 15A ATC fuse for 12 volt systems (use 7.5A for 24 volts) and an ATC fuse holder are included. If an on/off switch is wired into the circuit, it should be rated for a minimum of 20 Amps.
AC/DC modules (101N0510) run on 12/24 volts DC and include wire leads, as above. They can also run on nominal 100 - 240 volts AC at 50 or 60 Hz.
These AC/DC modules have two additional spade-style AC terminals for connecting the included 115 volt AC power cord (which has a two-push-on connectors at the refrigerator end, and a two-prong plug at the power source end).
If you want to run the refrigerator on European 230 volt or US 240 volt systems, you will need to provide your own power cord with a mains power plug which complies with applicable electrical safety regulations.
Note - Due to the double insulated design of the electronic unit, no earth connection is needed.
AC and DC power supplies can be connected to the electronic module at the same time. AC will be the preferred power supply source when both AC and DC power are available.
