The BTF2DC-2.3Z to BTF2CC-4.3G series are industrial-grade semi-hermetic reciprocating refrigeration compressors, designed for continuous heavy-duty operation in commercial and industrial refrigeration systems.
Motor and compressor are integrated within a single precision cast iron housing, eliminating shaft seal leakage risk. Compared to open-type compressors, refrigerant containment is significantly improved, maintenance intervals are extended, and total lifecycle cost is reduced.
The heavy-duty cast iron cylinder block and crankcase deliver exceptional vibration dampening, thermal stability, and mechanical rigidity — ensuring reliable performance under sustained high-pressure and high-temperature operating conditions.
A built-in control and protection module — clearly marked with safety warning labels — is mounted directly on the compressor body. This consolidated design simplifies field wiring, accelerates commissioning, and reduces external component count.
Multiple suction and discharge ports support flexible piping arrangements and broad compatibility with diverse refrigeration circuit designs, reducing system engineering complexity.
Four reinforced mounting feet with vibration-damping capability ensure stable installation, minimize structure-borne noise transmission, and reduce mechanical stress on connected pipework.
Model range covers BTF2DC-2.3Z to BTF2CC-4.3G, offering multiple cooling capacity options and refrigerant compatibility configurations. OEM/ODM support is available.
Please provide your system requirements — operating temperature range, target refrigerant, voltage/frequency, and required cooling capacity — for model selection and quotation.
Specifications subject to confirmation. Contact our technical team for detailed datasheets and application support.

This is the mid-size four-cylinder range of the Blait second-generation semi-hermetic reciprocating refrigeration compressor line, covering eight models from YBF4VCS-6.2Z to YBF4NCS-20.2G with nominal motor power from 6 to 20 HP and displacement from 34.73 to 56.25 m3/h at 50 Hz.
All models are four-cylinder machines on a common 42 mm stroke with four bore steps of 55, 60, 65 and 70 mm, giving displacements of 34.73, 41.33, 48.50 and 56.25 m3/h so one plant layout can be filled at different duty sizes.
The oil suffix sets the refrigerant: R is the mineral-oil build for R22 and R502, and E is the POE ester-oil build for R404A plant. Both refrigerant groups, R22 and R404A/R507A, are standard builds with complete capacity data behind them. The Z suffix denotes the medium-low temperature version with a type-2 motor; G denotes the medium-high temperature version with a type-1 motor.
Every model uses a PW part-winding start motor on 380 to 420 V three phase 50 Hz, with a 440 to 480 V 60 Hz build available. Maximum working current is 14 to 37 A, starting current 39 to 97 A and locked-rotor current 68 to 158 A.
Lubrication is by splash with a 2.6 litre oil charge and a 120 W crankcase heater. Weight including oil is 127 to 142 kg. Suction ports are 28, 35 or 42 mm and discharge ports are 22 or 28 mm.
Ratings are stated at 20 K suction superheat with no liquid subcooling, at 30, 40 and 50 degrees Celsius condensing and evaporating temperatures from plus 7.5 down to minus 45 degrees Celsius depending on model. Typical duty is commercial refrigeration, medium-temperature cold storage, food and beverage processing and pharmaceutical cold chain.
