Key Features:
Suggested Bitzer Cross-Reference: Selected models can be matched to common Bitzer ECOLINE series (e.g., 2CES, 4FES, 4PES). Please contact our team to confirm the correct equivalent for your application.
Innovative Alloy Valve Plate: The unique airway design envelops the high-temperature zone with low-pressure suction gas, significantly reducing discharge temperatures and boosting capacity.
Triple Oil Filter System: Integrated with three filters to maximize filtration area, helping ensure abundant lubrication and minimizing mechanical wear even if the oil is contaminated.
Optimized Cylinder Cooling: Specialized gas passages effectively lower cylinder head temperatures and rapidly vaporize inhaled liquid, helping prevent liquid hammer.
Ideal Applications: Commercial cold rooms, quick-freezing tunnels, and heavy-duty industrial refrigeration requiring both medium-high and ultra-low temperatures.
