Daikin RC112YENE Marine Refrigeration Compressor

Daikin Compressor RC112YENE

The Daikin RC112YENE (also designated as RC112-YENE) is an industrial-duty, hermetic motor-compressor engineered specifically for demanding shipboard refrigeration plants, provision room cooling modules, and specialized maritime/offshore air conditioning units. Built in Japan by Daikin Industries, Ltd., the RC112 series is recognized across marine engineering divisions for its high volumetric efficiency, resilience against ship-hull mechanical vibrations, and reliable vapor-compression performance under wide ambient variations.

Operating on a dual-frequency electric motor winding profile (380–415V @ 50 Hz / 400–440V @ 60 Hz, 3-Phase), the unit interfaces seamlessly with standard marine auxiliary generator buses. Primarily rated for R22 systems and charged with chemical-grade Suniso 4GSD mineral oil, this compressor delivers nominal cooling outputs between 3.0 to 4.0 Tons of Refrigeration (TR) (approx. 10.5 kW to 14.0 kW), making it a workhorse for mid-tonnage marine cold-chain systems.

Frequently Asked Questions

What is the operational voltage and frequency rating of the Daikin RC112YENE?

The Daikin RC112YENE is built for dual-frequency international maritime grids. It operates at 380–415 Volts at 50 Hz (3-Phase) and 400–440 Volts at 60 Hz (3-Phase), matching standard shipboard auxiliary generator output profiles.

Which refrigerant gases are supported by the Daikin RC112YENE?

The unit is factory-designed for R22 using Suniso 4GSD mineral oil. It can also operate with low-GWP and non-ODS retrofit service blends such as R417A, R422D, and R427A, provided correct lubrication management and superheat adjustments are made on the thermal expansion valve.

What is the cooling capacity output of the Daikin RC112YENE?

The compressor delivers a nominal cooling output between 3.0 and 4.0 Tons of Refrigeration (TR), translating to roughly 10.5 kW to 14.0 kW depending on evaporating temperature and vessel condensing conditions.

Can the RC112YENE replace obsolete Daikin marine compressor models?

Yes. The RC112YENE frequently replaces earlier legacy Daikin reciprocating and early-generation hermetic/semi-hermetic units within the 3–4 HP and 3–4 TR range, utilizing standard mounting footprint dimensions. Check port sizing and line orientation prior to final fit-up.

What oil should be used when topping up or servicing the compressor?

For R22 systems, use only Suniso 4GSD or an equivalent approved ISO VG 55 naphthenic mineral oil. If running POE-compatible refrigerants, execute a full flush and fill with an appropriate marine-grade Polyolester oil.

Are performance test certificates provided with reconditioned units?

Yes. Each reconditioned RC112YENE compressor undergoes hydrostatic pressure testing, continuous insulation resistance tests (Megger), vacuum holding verification, and mechanical bench testing prior to packaging and dispatch.
