• Precision-designed electrical terminal box: Very precise design of the compressor electrical terminal box and its secure connection for maximum safety.

• Concentrated stator coil winding: The coil winding height is reduced, which lowers copper usage and increases compressor efficiency at medium and low speeds, thus improving the device’s annual performance factor.

• Very high speed: Operating at extremely high speeds of 10-14 revolutions per second, offering a wide speed range.

• Equipped with internal oiling structure: Using the internal oil cycle method reduces compressor-generated heat, decreases oil injection, and increases compressor efficiency and reliability.

• Optimized discharge section structure: Reduced compressor noise and vibration with output adjustment buffers.

• Positive displacement gear pump: Ensures proper lubrication of parts at both low and high frequencies, delivering oil to all moving parts, ensuring smooth compressor operation and improved efficiency.

• Balanced dynamic oil distribution structure: Oil balance pipe ensures equal oil distribution in compressors that are running in parallel.

• Use of high-quality bearings: Bearings used in compressors are self-adjusting cylindrical types, optimizing and ensuring reliable operation.

• Use of refrigerant pressure tap valve: This valve and method allow pressure modulation for the discharge line, increasing compressor efficiency at medium and partial loads.

• Direct suction system: The pre-heating direct suction system in the compressor increases its efficiency.

• Internal system pressure equalizer: This system regulates the compressor’s pressure according to the system’s operating pressure, enabling operation under different pressures and improving compressor performance.

Cooling and Heating with Double Enthalpy Technology
Baumen VRF systems, using double enthalpy technology, maintain effective cooling and heating even in extremely harsh temperature conditions:

• Effective cooling at very high temperatures up to 56°C during summer

• Stable heating at very low temperatures down to -30°C in winter

• Significant reduction of defrost cycles to maintain stable heating below zero

• Elimination of annoying refrigerant noise during saturation via EXP

• Reduction of compressor compression chamber temperature by up to 30% for increased efficiency and device lifespan

Optimized Compressor Compression Chamber
In Baumen VRF systems, the compression chamber is designed with advanced, optimized spirals for efficient R410A refrigerant compression, offering notable benefits:
