BTF4DC-5.3Z
Blait
The BTF4DC-5.3Z four-cylinder piston refrigeration compressor is a flagship product of Blait’s T-Series, engineered exclusively for high-demand industrial refrigeration systems. Boasting a compact design, balanced piston structure, and exceptional energy efficiency, this compressor delivers stable and reliable performance for medium to low-temperature cooling applications. It is compatible with refrigerants like R22 and R134a, making it a versatile choice for customizable OEM projects and commercial refrigeration needs. Whether for continuous operation in cold storage or precise cooling in food processing, the BTF4DC-5.3Z stands out as a durable and cost-effective solution for industrial cooling.

Equipped with a four-cylinder piston structure, the compressor ensures balanced load distribution, minimizing mechanical vibration and enabling long-term continuous operation. The 50 mm bore and 39.3 mm stroke design guarantees consistent refrigerant output, even under demanding industrial conditions.
Optimized for energy savings, the compressor features impact-resistant spring steel valves to reduce airflow leakage and minimized deadpoint clearance for enhanced compression efficiency. Its 5 HP (3.7 kW) high-load motor maintains peak performance while cutting energy consumption, making it an eco-friendly choice for industrial facilities.
Built with low-friction piston rods, chrome-plated rings, and surface-hardened crankshafts, the BTF4DC-5.3Z resists wear and tear for an extended service life. The forced lubrication system and large oil pump ensure continuous oil supply, reducing maintenance frequency and operational costs.
The precision-engineered components and balanced multi-cylinder layout significantly reduce operational noise and vibration, creating a quieter working environment for industrial settings.
Integrated motor temperature protection and discharge temperature protection prevent overheating and system failures. Pressure sensors trigger automatic shutdowns during abnormal conditions, safeguarding both the compressor and connected refrigeration systems.
With over two decades of expertise in refrigeration technology, Blait is a trusted leader in industrial compressor manufacturing. Our core strengths include:
A dedicated R&D center in Hangzhou staffed by 24 engineers, driving continuous product innovation and quality enhancement.
Partnerships with top academic institutions like Xi’an Jiaotong University, ensuring cutting-edge design and efficiency optimization.
Strict quality control certified by ISO9001, ISO14001, and ISO45001, with each compressor undergoing performance and airtightness testing before delivery.
Comprehensive testing facilities with imported high-precision instruments, guaranteeing reliable and consistent product performance.
Flexible OEM and customized solutions to meet unique project requirements, supported by professional technical support.
