Understanding Bitzer Semi-Hermetic Compressors: Efficiency and Reliability for HVAC & Refrigeration Systems
Bitzer is a global leader in compressor technology, and their semi-hermetic compressors are renowned for combining robust construction, high efficiency, and versatile applications. At Boulton Trading Corporation, we proudly supply Bitzer semi-hermetic compressors that meet the demanding needs of commercial and industrial refrigeration and HVAC systems.

What Are Semi-Hermetic Compressors?
Bitzer semi-hermetic compressors feature a sealed compressor and motor housing, offering enhanced protection and durability. Unlike hermetic compressors, the semi-hermetic design allows servicing and component replacement, extending equipment lifespan and reducing downtime. This design is ideal for applications requiring reliability and easy maintenance.
Key Features of Bitzer Semi-Hermetic Compressors
- Robust and efficient motor technology: The suction gas-cooled motor reduces operating temperatures, enhancing durability and energy efficiency.
- Optimized valve plates and drive gear: Ensure smooth operation with minimal energy consumption and high performance across a wide load range.
- Compatibility with multiple refrigerants: Including standard HFCs, low-GWP refrigerants, and natural refrigerants like CO₂ and hydrocarbons.
- Capacity control options: Including stepless and multi-stage control for precise system regulation and energy savings.
- Range of sizes and capacities: Suitable for various HVAC and refrigeration applications—from medium to low temperatures, cold storage, blast freezing, and process cooling.
