BTF4G-30.3G
Blait
The BTF4G-30.3G High-Pressure Four-Cylinder Reciprocating Refrigeration Compressor is a heavy-duty solution engineered for superior cooling capacity, stable performance, and 24/7 industrial reliability. As part of Blait’s T-Series, this compressor features a robust four-cylinder design that minimizes vibration, enhances heat dissipation, and delivers consistent cooling output for demanding applications. Optimized for energy efficiency and cost-effectiveness, it supports mainstream refrigerants and adapts to diverse industrial and commercial refrigeration needs, from cold storage to chemical cooling systems.

The four-cylinder structure (4 × 75 × 55 mm) enables efficient compression of gases to high pressure levels, making it ideal for heavy-duty cooling tasks. Available in single-stage and multi-stage options, it accommodates pressure requirements ranging from low-pressure gas transfer to high-pressure industrial processes.
Equipped with positively locked pistons, the compressor allows precise setting of end clearance, maximizing efficiency while reducing wear on piston and cylinder components. This design ensures long-term operational stability and consistent performance even under continuous use.
Critical parts such as crossheads (cast iron) and valve seats are made from corrosion-resistant materials, withstanding harsh operating environments (e.g., chemical cooling, high-humidity settings) and preventing galling or degradation over time.
A pressure-lubricated crankcase with an integrated filter ensures continuous lubrication of internal moving parts (crankshaft, connecting rods, bearings). This minimizes premature wear, extends service life, and maintains optimal performance during extended operation.
Supporting OEM and custom solutions, the compressor offers flexible mounting options (skid-mounted or plant-specific layouts) and configurable parameters (refrigerant type, voltage settings). It adapts to unique project requirements, from standard industrial setups to specialized cooling systems.
Specialized Refrigeration Expertise: Blait focuses exclusively on industrial and commercial refrigeration compressors, with over a decade of manufacturing experience and a proven track record of reliability.
Advanced R&D & Testing: An independent R&D center and collaboration with leading universities drive innovation, while three professional testing stations ensure compliance with GB/T 5773-2004, GB/T 10079-2018, and GB/T 19410-2018 standards.
Energy-Efficient Design: Optimized structures and real-time performance monitoring reduce energy consumption and operating costs without compromising cooling capacity.
Comprehensive Support: Offers professional technical support, installation guidance, operation training, and after-sales service to ensure seamless integration and long-term value.
