Bitzer Semi Hermetic Air Cooled Condensing Unit 4FES-3Y R404a 3HP Low Temperature

Bitzer Semi Hermetic Air Cooled Condensing Unit​​
 

The air-cooled condensings unit should not be installed in the space with intense heat and high degree of wetness, they are  adopt shell-and-tube water-cooling condensers, the heat transfer tubes are high-efficiency and dense-ribbed copper tubes, the tube boxes at both ends can be disassembled and replaced when necessary, so as to facilitate the connection of the cooling water tubes, the unit can be matched with the chocolate industry, ice cream industry, etc. .

Stable performance, high efficiency and energy saving. COMPRESSOR FEATURES: With a durable valve design, high-quality wear-resistant bearing components and easy maintenance, use and speed control, smooth operation, and equipped with efficient, suction cooling motor.

The octagonal machine series has a very compact design and more stable operation characteristics. The 4J-13.2 compressor, for example, uses an internal oil recovery system that has proven to be efficient and reliable over the years.

Bitzer Semi Hermetic Air Cooled Condensing Unit​ Features:

1. Special Valve design, high efficiency and stability, long service life.

2. Refrigeration capacity, energy efficiency ratio (COP) higher than other brands of compressors 20%.

3. Good low temperature performance, for R22 refrigerant, single-stage compressor evaporation temperature up to-40 °c

4. Used in a variety of refrigerants (R12, R22, R502, R134a, R404a, R507) . Compliance with environmental requirements.

5. Using split coil to start, reduce the starting current, reduce the impact on the power grid, the motor has special design technical parameters and newly developed stator and rotor components, increased efficiency and power factor.

6. A wide range of applications: Buzel compressor is divided into high-temperature type and low-temperature type, high-temperature type evaporation temperature up to 12.5 °C, low-temperature type single-stage compressor evaporation temperature up to (R22)-40 °C, double-stage compressor evaporation temperature up to (R22)-50 °C. If R404A or R507 is used, the evaporation temperature will be lower, reaching-70 °C.

7. Energy Regulation Wide: 4 cylinder compressor energy regulation range 50% , 100% , 6 cylinder compressor energy regulation range 33% , 66% , 100% . When the refrigeration system load changes when effective regulation to reduce operating costs.

8.Built-in motor overload protector (INT69VS) , effective protection of motor due to increased refrigeration system load or insufficient refrigerant return refrigeration system, resulting in motor overload, overheating.

9. In order to prevent the starting current is too large, you can also choose to uninstall the starting device.
