Monoblock chillers with screw compressors

For the air conditioning systems of hospitals, offices, industrial, public and residential buildings

Monoblock chillers with screw compressors are the latest generation of high-efficiency air-cooled water chillers with air-cooled condensers. Today these types of chillers are often used to cool water in the air conditioning systems of public and residential buildings.

D7 supplies monoblock chillers intended for outdoor installation. These units feature extra-strong housing and do not require additional protection from precipitation.

Compact and reliable, they can operate in heavy-duty mode.

Screw compressors outperform reciprocating models on several key metrics Usually, their COP reaches 5.4 in cooling mode and 4.5 in heating mode. The important benefits of this design include its compact size, high reliability of the mechanical parts, and low noise and vibration levels.

Main technical parameters:

• Models with a cooling capacity of 375 to 1,420 kW
• BITZER screw compressor with the R-134A refrigerant
• Evaporator outlet temperature: 5 to 15°C
• Ambient temperature: 15 to 43°Cr
• The temperature difference between chilled water inlet and outlet: 4–8°C
• Four levels of power adjustment: 25, 50, 75 and 100%
• Insulated shell and pipe evaporator
• Built-in temperature, oil level and refrigerant pressure sensors

Options:

• Smooth regulation in the range of 50–100%
• Flow switch
• Vibration mounts
• Remote controller
• Reinforced housing
• Additional fan protection

Tested and ready to go!
Each unit is filled with refrigerant and put through a full factory testing cycle.
