BD35F cooling unit with control unit – 12/24V – code: SBC00023XA – Isotherm
BD35F cooling unit with 12/24V control unit Isotherm – code SBC00023XA
This Isotherm cooling unit with compressor BD35F is a solution designed for onboard refrigeration systems and applications where reliable components easily integrated into an existing system are needed. The unit is supplied with electronic control unit for power supply 12/24V and with fin condenser (upper ventilated condenser, as per original description), in a format suitable as a replacement or as a base for a complete installation.
The system is described as cooled directly by the surrounding water, operating independently of the air temperature inside the boat: a typical setup for solutions dedicated to boating, where heat and space management is a central aspect. The unit is supplied precharged with R134a gas and with quick couplings to facilitate connection operations.
Features and construction details
BD35F compressor and electronic control unit
The heart of the unit is the BD35F compressor, paired with a electronic automatic control unit. The control unit integrates a protection function that automatically switches off the unit when the battery voltage drops below:
- 10,4 to 12 volts
- 22,8 to 24 V
This intervention logic is useful in the nautical field to preserve the battery and maintain a more controlled management of on-board electrical loads.
Finned capacitor (top ventilated)
The unit includes a fin condenser (also referred to as top ventilated capacitor). It is a fundamental component for dissipating heat from the refrigeration circuit and for the proper functioning of the unit as a whole.
Quick couplings and gas precharge
The unit is supplied complete with quick couplings and precharged with ecological gas R134a. These elements are particularly appreciated in maintenance and retrofit because they can simplify connection phases and reduce intervention times, in compliance with the technical procedures provided for refrigeration systems.
12/24V power supply
The unit is designed to operate with a power supply 12/24V, a typical feature of on-board electrical systems and many direct current installations.
Indicated consumption
The available data shows a consumption of 320/380 W / 24h (with reference note conditions: 38° external, in the box 5°). This is a value related to specific test/use conditions reported in the existing datasheet.
Evaporator not included
As indicated in the original content, the’evaporator must be purchased separately. This allows you to choose the evaporator best suited to the volume of the fridge compartment and the system configuration, keeping the refrigeration unit as the base of the system.
Typical applications (nautical and onboard plant engineering)
This refrigeration unit is indicated as a component for:
- Onboard refrigerators and refrigeration systems in the nautical field
- Spare parts for replacement of existing units with 12/24V power supply
- Installations where a unit with electronic control unit and low voltage protection
The presence of quick couplings and of precharged R134a makes the product consistent with scheduled maintenance or functional restoration interventions, always in compliance with regulations and good installation practices.
Operational advantages
Battery protection through electronic control
The automatic shutdown function below the voltage threshold (10.4 at 12V and 22.8 at 24V) helps to manage DC power supply more safely, reducing the risk of excessive discharge during use.
Simpler integration during installation
The equipment with quick couplings and the precharge of the circuit (R134a) are elements that, in an installation or replacement context, can make some operational phases more straightforward and facilitate an orderly commissioning, compatible with the system configuration.
Modular solution: selectable evaporator
The fact that the evaporator is not included allows a modular approach: you can choose the component best suited to your fridge compartment and installation needs, without constraints on a single format.
Usage and notes for selection/order
Product code and identification
For the correct identification of the spare part, refer to the code SBC00023XA. This is the main data to use during technical requests or comparison with the unit to be replaced.
Power supply and system check
- Check that the system is compatible with power supply 12/24V.
- Consider the presence of the electronic control unit and low voltage protection logic.
Check clearances
Before installation, check the available space and compare the dimensions provided (available in two variants in the data). In case of installations in tight technical compartments, this check is particularly important.
Components necessary for a complete system
To complete the refrigeration system, it is also necessary to provide the’evaporator (not included). Depending on the configuration, additional components and installation accessories not specified in this sheet may be required.
