1. Model Number Decoding (6J-332Y-40P):
-
6J: Indicates the compressor series and frame size. The “J” series typically denotes a specific cylinder configuration and displacement class from YORK’s extensive line.
-
332: Specifies the total displacement of the compressor, which is 332 cubic inches per revolution. This is a key indicator of its capacity.
-
Y: Represents the type of motor and electrical configuration. “Y” often indicates a specific winding type or motor design optimized for reliable starting and running under load.
-
40: Denotes the Motor Power. In this context, “40” signifies a 40 HP (Horsepower) polyphase electric motor.
-
P: Indicates the Type of Pump (Compressor). “P” in YORK nomenclature typically stands for a Low-Temperature (LT) or “Low Temp” pump, meaning it is engineered for applications with low evaporating pressures (e.g., blast freezing, cold storage below -10°F).
2. Key Specifications & Features:
-
Type: Semi-Hermetic Reciprocating.
-
The motor and compressor are housed in a single, sealed cast-iron crankcase.
-
The design is “serviceable,” meaning major components like valves, pistons, and bearings can be accessed and repaired in the field by removing the cylinder head and motor end-cover, offering long-term serviceability and reduced lifecycle cost compared to fully hermetic units.
-
-
Displacement: 332 cubic inches (approx. 5.44 liters per revolution).
-
Motor Power: 40 HP (approximately 30 kW), 3-phase.
-
Speed: Designed for direct drive (no gearbox) at common motor speeds such as 1750 RPM (for 60 Hz) or 1450 RPM (for 50 Hz). The “1928 BAR” in your query is likely a typographical error; “1928 RPM” would be an unusual speed for a 60Hz motor (typical is ~1750 RPM). The standard operating speed should be confirmed via the compressor’s data plate.
-
Protection Rating: IP54
-
IP5x: Protected against dust ingress (limited ingress permitted, but not harmful to operation).
-
IPx4: Protected against water splashes from all directions. This makes it suitable for environments with occasional washdown or high humidity, common in food processing and cold storage facilities.
-
-
Refrigerants: Originally designed for traditional halogenated refrigerants (e.g., R-22, R-502). With proper materials compatibility (e.g., POE oil), it can often be adapted for use with modern HFCs (like R-404A, R-507, R-134a) or Hydrocarbon/Natural Refrigerants after a thorough system evaluation and component changes by a qualified technician.
- LP/HP MAX: 19/28 BAR
-
Design Features:
-
Heavy-Duty Construction: Cast iron bodies, forged steel crankshafts, and durable bearing surfaces for extended life.
-
Forced Feed Lubrication: Positive pressure oil pump ensures reliable lubrication to all critical components under varying operating conditions.
-
Valve Design: High-efficiency ring plate or reed valves for good volumetric efficiency and capacity modulation.
-
Capacity Control: Often equipped with multi-step (e.g., 33%, 66%, 100%) or unloaded start capacity control to reduce starting current and match cooling load.
-
