The Pramac GBW22Y-1P is a European-manufactured, single phase silent diesel generator delivering 14 kVA / 14 kW standby power and 13 kVA / 13 kW prime power. Its Stage V Yanmar engine, durable Linz alternator and straightforward MCP key-start panel make it a dependable choice for manually controlled backup or primary power.
Operating at 230V and 50Hz with a power factor of 1, the GBW22Y Single Phase provides its full rated output in both kVA and kW. This makes its capacity particularly easy to assess when matching the generator to compatible 1 phase electrical loads.
Its principal power ratings are:
As a 14 kVA generator, the GBW22Y-1P is designed to provide emergency standby electricity during a mains failure. Under ISO 8528 conditions, its ESP rating can be used for up to 200 operating hours per year, with the average output over any 24-hour period limited to 70% of the standby rating.
For applications requiring regular power, the 13 kVA generator rating represents the maximum output available while supplying a variable load for an unlimited number of hours per year, subject to the manufacturer’s prescribed maintenance intervals. The permissible average output over 24 hours remains limited to 70% of prime power.
Correct generator sizing should consider the normal running load, motor starting currents, load steps and future capacity requirements. If an application sits close to this model’s limit, moving up from a 10 kVA generator may provide valuable additional headroom and reduce the likelihood of overloads.
At the heart of the GBW22Y 1 Phase is the naturally aspirated Yanmar 4TNV88-BIPGE diesel engine. This water-cooled, four-cylinder inline engine has a displacement of 2.19 litres and runs at 1500rpm, supporting durable operation in both standby and prime-power installations.
The engine meets Stage V exhaust emissions requirements at 50Hz. This makes the GBW22Y-1P especially relevant to buyers seeking a modern industrial diesel generator for use in markets where current European non-road emissions standards apply.
Its direct-injection fuel system includes a Bosch inline fuel pump and paper-element fuel filter. A forced-feed lubrication system, replaceable oil filter and thermostatically controlled cooling system support dependable performance and practical routine servicing. The engine has a 7.4-litre oil capacity and a 2.7-litre coolant capacity.
For users comparing output in real power, this model also serves as a 14 kW generator during emergency standby operation. Its 13 kW prime rating gives it more continuous-load capability than a typical 10 kW generator while retaining relatively compact dimensions.
The Yanmar engine is paired with a Linz E1S13MF alternator configured for 230V single phase output. This four-pole, brush-type alternator has Class H insulation, IP21 protection and an efficiency of 86.5% at 75% load.
Voltage tolerance is ±4% from no load to full load under the stated operating conditions. The alternator also produces a waveform with less than 5% harmonic content, helping it support a broad range of compatible equipment, including loads that can distort the electrical waveform.
The alternator can deliver short-circuit current exceeding rated current by three times, supporting the correct operation of electrical protection devices. It can also normally accommodate a 10% overload for one hour in every six hours. These capabilities should not replace correct load assessment, cable sizing or professional installation, but they provide useful resilience when dealing with short-duration demand changes.
With a maximum output current of 62.17A on its single phase, this 230V generator is protected by a 63A circuit breaker. Final electrical connections should always be designed and completed by a suitably qualified installer in accordance with the site, load and applicable regulations.
This version of the GBW22Y-1P is supplied with Pramac’s MCP manual control panel. It is a key-start diesel generator intended for applications where an operator will be present to start and stop the set, rather than an automatic mains-failure system.
The panel includes:
The MCP provides alarms for battery-charging failure, low oil pressure, high engine temperature and earth faults. Shutdown protection is provided for battery-charging failure, low oil pressure and high engine temperature, alongside circuit-breaker protection.
This manual start generator does not provide the automatic operating functions of the separately available ACP configuration. Buyers requiring automatic startup following a mains failure should therefore select the appropriate automatic-control version and compatible transfer equipment.
The GBW22Y Single Phase is enclosed within a sound-attenuated canopy incorporating polyurethane acoustic material and an internal residential silencer. It produces a sound pressure level of 64 dB(A) at 7m, with a guaranteed sound power level of 93 dB(A).
This makes it a practical 14 kVA silent diesel generator for commercial premises, workshops, farms, construction support, telecommunications equipment and other locations where controlling operating noise is important. Actual sound experienced on site will depend on positioning, surrounding surfaces, distance and installation conditions.
The single-piece hinged canopy is supported by pneumatic arms and fitted with handles, allowing it to lift for straightforward access during inspections and maintenance. A central lifting eye simplifies handling, while appropriately sized anti-vibration mountings help isolate engine and alternator movement from the welded steel base frame.
A 51-litre plastic fuel tank is integrated into the generator’s base. It includes a filler neck, breather, external refilling point and visual fuel-level indicator.
At 75% of prime power, the GBW22Y-1P consumes approximately 3.52 litres/hour and provides a calculated running time of 14.49 hours. At 100% prime load, consumption rises to approximately 4.67 litres/hour, giving around 10.92 hours of operation from the full tank.
These figures provide a useful basis for fuel planning, although real-world consumption and autonomy will vary with electrical demand, ambient conditions, servicing, fuel quality and operating practice. For regular prime-power use, buyers should also plan suitable refuelling arrangements and follow the prescribed maintenance schedule.
Despite its industrial construction, the GBW22Y 1 Phase has a relatively compact footprint. It measures 1645mm long, 870mm wide and 1072mm high, with a dry weight of 495kg. Integrated support feet and the central lifting point assist with positioning, transport and installation.
This 13 kVA single phase generator is well suited to properties and equipment operating from a conventional 230V supply. Potential applications include backup power for smaller commercial buildings, rural premises, workshops, site facilities and selected residential systems, as well as primary power for remote locations without a dependable mains connection.
The Pramac GBW22Y-1P combines useful single phase capacity with a proven Yanmar engine, Stage V emissions compliance, a quiet canopy and uncomplicated manual control. For buyers who do not require automatic mains-failure operation, it offers a robust and accessible 13 kW diesel generator for professionally installed standby or variable-load prime-power applications.
