Bitzer Spare Parts List for Semi-hermetic Compressor Replacement

There are a lot of Bitzer parts you will need for repairing the compressor. You may need to have a list, a Bitzer spare parts list which is clear to know which you will need.

Now are going to show you the Bitzer spare parts list:

1. Thermistor Protectors

The functions and uses of thermistor protectors in HVAC&R refrigeration semi-hermetic compressors mainly include the following aspects:

Overload protection: When the compressor current exceeds the rated value, the thermistor protector will sense the increase in temperature and cut off the circuit, thereby protecting the compressor from overload damage.

Overheating protection: The thermistor protector can detect the temperature of the compressor when it is running. When the temperature exceeds the safe range, the protector will cut off the power to prevent damage caused by overheating of the compressor.

Short circuit protection: When a short circuit occurs in the circuit, the thermistor protector can respond quickly and cut off the power supply to avoid damage to the compressor and other parts of the circuit.

Start-up protection: When the compressor starts, the current will increase instantly. The thermistor protector can limit the starting current and protect the motor and other components inside the compressor.

Thermistor protectors play a key protective role in semi-hermetic refrigeration compressors, so when we make thermistor protectors, we use thermistor components with stable temperature sensitivity and fast response time; To ensure the performance and life of the thermistor, we choose packaging materials with good heat resistance and insulation properties.

Our factory can provide reliable thermistor protectors. To ensure that the life of the semi-hermetic compressor you use is extended, please choose our protectors. We welcome your consultation at any time and accept customized services.

2. Electrical Terminal Plate

The terminal plate plays a key electrical connection and protection role in Bitzer semi-hermetic compressors and Bitzer screw refrigeration compressors. The terminal plate we provide has good temperature resistance, insulation, corrosion resistance, mechanical strength, and electrical conductivity. Our terminal plates are widely used in the maintenance, refurbishment, rebuilding, and remanufacturing of semi-hermetic refrigeration compressors and screw refrigeration compressors. We provide replacement of 9 pins terminal plate, 6 pins terminal plate, and 3 pins terminal plate for Bitzer compressors.

3. Oil Heater

The crankcase oil heater plays an important role in Bitzer refrigeration compressors. By heating the lubricating oil, it ensures its fluidity and lubrication performance in low-temperature environments, thereby ensuring the normal operation and long service life of the compressor. We use high-quality stainless steel, copper, and nickel alloys, which have good high temperature resistance and corrosion resistance. Our reasonable design makes installation more convenient and provides comprehensive safety protection measures to ensure the efficient and safe operation of the oil heater.

4. Stator & Rotor

To ensure that the motor has high efficiency, long lifespan, and high reliability, we use high silicon steel sheets with high magnetic permeability and low loss characteristics, as well as high-purity oxygen free copper wires as raw materials. Our Stator&Rotors are widely used in the maintenance and refurbishment of semi-hermetic refrigeration compressors.

5. Connecting Rod & Piston

We offer two different manufacturing processes for connecting rods, one is cast connecting rods. Cast connecting rods may have internal defects, and their quality and reliability are relatively low, but they have a price advantage. Another type is forged connecting rods, which have a dense internal structure, higher quality and reliability, and are relatively expensive. You can choose connecting rods of different processes qualities according to the situation of your Bitzer semi-hermetic compressor.

At the same time, we also provide pistons with different manufacturing processes, one of which is pressure cast pistons. The metal structure of pressure cast pistons is relatively dense, reducing defects such as porosity and shrinkage. Another type is semi-solid casting piston, with a metal structure that has higher precision and density. You can choose pistons with different process qualities according to the situation of your Bitzer semi-hermetic compressor.

6. Gasket set

Bitzer semi-hermetic compressor gaskets are consumer products in the field of compressor maintenance and refurbishment. We can provide large quantities of rubber gaskets that are resistant to high pressure, temperature, and oil, asbestos gaskets, and metal gaskets.

7. Bitzer Valve Plate Assembly

To ensure the high efficiency and practicality of the semi-hermetic refrigeration compressor, we provide valve plates made of corrosion-resistant, wear-resistant, and high-strength stainless steel materials. Through precision stamping, heat treatment, and surface treatment processes, we manufacture high-performance and durable valve plates to meet the needs of HVAC refrigeration compressors.

We can provide valve plates for Bitzer semi-hermetic compressors and screw compressors. If you have any business in repairing or refurbishing compressors, please feel free to contact me for inquiries.

11. Oil Firlter

The main function of oil filter is to filter impurities in lubricating oil, such as metal shavings, dust, dirt, etc. If these impurities enter the moving parts of the compressor, they may cause wear, blockage, and even damage the compressor. By filtering lubricating oil, oil filtration can effectively protect the internal components of the compressor, such as bearings, pistons, valves, etc., extend their service life, and improve the reliability and stability of the equipment.

In all, you shall need to know the parts list of Bitzer compressor before you are buying, hope this Bitzer spare parts list is helpful to you.

12. Protection Module

The important functions of the protection module in the Bitzer semi-hermetic compressor include overload prevention, overheating protection, phase loss protection, overvoltage and undervoltage protection, phase sequence protection, start-up protection, pressure protection, oil level and oil pressure protection.

By using protection modules, refrigeration semi-hermetic compressors can achieve intelligent monitoring and protection, effectively preventing faults, ensuring the safe operation of equipment, extending service life, and improving the reliability and stability of the overall system.

We can provide Gold Air protection module model SE-B1, SE-E1, SE-B2, and OUT69 for Bitzer compressors.
