REFRIGERATION ACCESSORIES IN KENYA
COPPER RODS FOR BLAZING
refrigeration accessories like Copper rods are essential components in refrigeration systems where they are primarily used for brazing, a process that joins metal components together using a filler metal alloy. For refrigeration brazing, the copper rods are typically made of copper-phosphorus alloys like BCuP-5 or BCuP-6, which have lower melting points than pure copper to facilitate the brazing process. These rods often have a flux coating that helps remove oxides and promote better wetting and adhesion of the molten filler metal. The copper rods’ excellent thermal conductivity, corrosion resistance, and compatibility with common refrigerants make them ideal for brazing connections between copper tubing, fittings, valves, and other refrigeration components. Proper brazing techniques like oxy-fuel or induction methods are used to create strong, durable brazed joints that can withstand the high pressures and harsh environments found in refrigeration systems.
Key features as refrigeration accessories
- Made of copper-phosphorus (CP) alloys like BCuP-5 and BCuP-6, which have a lower melting point than pure copper, facilitating the brazing process.
- Often coated with flux material to remove oxides and contaminants, promoting better wetting and adhesion during brazing.
- Compatible with common refrigerants such as R-134a, R-410A, and the phased-out R-22.
- Brazed copper joints are strong and durable, suitable for high-pressure refrigeration applications.
- Excellent thermal conductivity for efficient heat transfer in refrigeration components.
- Good corrosion resistance, essential for humid or moist environments.
- Used for joining various components like copper tubing, fittings, valves, and heat exchangers.
- Oxy-fuel (oxy-acetylene) and induction brazing are common techniques for brazing copper in refrigeration systems.
FRIDGE THERMOSTAT
A fridge thermostat, also known as a refrigerator temperature control or cold control, is a crucial component in refrigeration systems that regulates the temperature inside the refrigerator or freezer compartment. It works by sensing the current temperature and cycling the compressor and other components on and off to maintain the desired cooling level. Fridge thermostats are designed to provide accurate temperature control, energy efficiency, and consistent performance, ensuring that food and perishable items are stored at safe and optimal temperatures.
Key Features as refrigeration accessories in Kenya
- Temperature sensing mechanism (e.g., bimetal coil, electronic sensor)
- Adjustable temperature setting control (e.g., dial, digital display)
- Automatic cycling of compressor and cooling components
- Energy-saving features (e.g., adaptive defrost, compressor delay)
- Fail-safe mechanisms to prevent over-cooling or over-heating
- Durable construction for long-term reliability
- Compatibility with specific refrigerator models and cooling systems
- Easy installation and replacement (e.g., snap-in, plug-in designs)
- Diagnostic capabilities (e.g., error codes, indicator lights)
- Potential for advanced features (e.g., Wi-Fi connectivity, remote monitoring)
Fridge thermostats play a critical role in maintaining the desired temperature range within refrigeration appliances, ensuring food safety, energy efficiency, and optimal performance while providing user-friendly temperature control and monitoring capabilities.
CHARGING HOSE
A charging hose in refrigeration systems is a flexible, high-pressure hose used to connect refrigerant cylinders or recovery tanks to the system’s service ports or charging valves. This allows technicians to safely add or remove refrigerant during installation, maintenance, or repair operations. Charging hoses are designed to withstand the high pressures and temperatures encountered in refrigeration systems, ensuring safe and controlled refrigerant transfer.
Key Features as refrigeration accessories
- High-pressure rating (e.g., 800 PSI or higher)
- Refrigerant compatibility (suitable for specific refrigerants)
- Durable construction (e.g., reinforced rubber, polymer lining)
- Varying lengths (e.g., 3 feet, 6 feet, or longer)
- Color-coded for easy identification of refrigerant type
- Quick-connect fittings for secure and leak-free connections
- Flexible for maneuverability in tight spaces
- Protective outer covering or casing
- Ball valve or shut-off valve for flow control
- Availability in sets with multiple hose lengths and fittings
Charging hoses are essential tools in the refrigeration industry. Enabling technicians to safely and efficiently handle refrigerants while minimizing the risk of leaks, contamination, or environmental issues.
