YBF4T-5.2DS~YBF4G-12.2DS
Blait
The YBF4T-5.2DS~YBF4G-12.2DS is a high-performance semi-hermetic reciprocating refrigeration compressor engineered exclusively for industrial and commercial cooling demands. Developed by Blait, a global leader in precision piston compressor solutions, this model features a durable double-stage structure that delivers exceptional energy efficiency and robust cooling capacity. Designed to thrive in demanding working environments,it ensures 24/7 stable operation—making it a reliable backbone for critical systems like cold storage, freezing equipment, and industrial refrigeration units. Whether for medium or low-temperature applications, the YBF4T-5.2DS~YBF4G-12.2DS balances compact design with powerful performance, maximizing productivity while minimizing energy consumption for businesses worldwide.
The innovative DSR double-stage compression design stands as the core of this compressor’s performance. It optimizes energy utilization by reducing compression ratios per stage, resulting in lower power consumption and stronger cooling output—even at low evaporation temperatures (as low as -40℃). This feature not only cuts operational costs but also enhances overall system efficiency, making it ideal for long-term continuous operation.
Crafted with a semi-hermetic design, the compressor body offers superior sealing performance, preventing refrigerant leakage and protecting internal components from external contaminants. This structural advantage extends the unit’s service life significantly, reducing the need for frequent repairs and ensuring consistent performance in harsh industrial settings.
Equipped with an advanced forced lubrication system and optimized valve mechanism, the YBF4T-5.2DS~YBF4G-12.2DS operates smoothly with minimal mechanical wear. The lubrication system delivers precise oil flow to critical components, while the enhanced valve design reduces pressure loss—guaranteeing reliable performance even during extended operating cycles.
Flexibility is key to this compressor’s versatility: it supports common refrigerants including R22, R404A, and R134a (depending on configuration). This compatibility allows seamless integration with existing cooling systems, eliminating the need for costly refrigerant replacements or system overhauls.
Designed with user convenience in mind, the YBF4T-5.2DS~YBF4G-12.2DS uses standardized components that simplify replacement and maintenance. This reduces downtime and lowers after-service costs, ensuring your cooling systems remain operational with minimal interruptions.
