Cubigel Compressors® is a global brand specializing in hermetic refrigeration compressors and condensing units for commercial and light-commercial HVACR applications. The company traces its roots to Europe. It is producing a wide range of compressors designed for high reliability, energy efficiency, and adaptability to different refrigerants and operating conditions.
About the
NBG Series (including NBG40CA)
it belongs to Cubigel’s NBG family of reciprocating compressors. Based on catalogue patterns and similar models:
Application
-
Designed for hermetic refrigeration use in commercial systems such as:
-
Display cabinets
-
Reach-in coolers / freezers
-
Beverage chillers
-
Small cold-rooms and other light commercial refrigerating equipment.
-
Typical Characteristics (for NBG-style models)
-
Compressor Type: Hermetic reciprocating compressor (motor and compressor sealed together).
-
Rated Performance Class: Likely in the Low Back Pressure (LBP) range — suitable for evaporating temperatures typical in chillers and cabinets (e.g., approx. −23 °C rating point with R290 refrigerant in comparable models).
-
Refrigerants: Designed to work with common refrigerants for commercial refrigeration, including natural refrigerants like R290 (propane) and potentially other options depending on configuration.
-
Voltage/Frequency: Standard versions in this range operate around 220–240 V at 50 Hz, suitable for Malaysian electrical standards.
Performance & Efficiency
-
Cubigel compressors typically offer high efficiency and reliable performance, with innovations focused on energy saving and reduced operational cost compared with older or lower-efficiency units.
-
Many models in similar displacement classes (~4 cc range) deliver approximately 130–200 W of cooling capacity at standard rating conditions (e.g., ASHRAE LBP –23.3 °C) with good COP values.
Design Attributes
-
Compact and robust design suitable for confined mechanical rooms or equipment housings.
-
Hermetic sealing helps prevent refrigerant leakage and contamination, boosting reliability and service life.
-
Designed to operate within typical grid voltage variations (±15 %) without performance loss.
