Engine Performance and Liquid Cooling System

One of the defining features of this liquid cooled Kohler generator is its 6.2-liter V-8 engine, designed specifically for continuous standby applications.

Air-cooled generators are common in smaller residential units, but large commercial generators require liquid cooling to maintain consistent performance under heavy loads.

The advantages of a liquid cooled standby generator include:

• Better heat management

• Longer engine lifespan

• Higher power output capability

• Quieter operation

• Greater reliability in hot climates

The engine runs at 1800 RPM, which reduces mechanical stress and extends service life compared to higher-speed generators.

Additional engine benefits include:

• Digital isochronous governor maintaining speed stability

• Advanced fuel management for NG and LP fuel

• Low harmonic distortion under heavy loads

These features ensure stable power for sensitive equipment such as:

• Servers and data systems

• Medical equipment

• Security systems

• Commercial refrigeration

• HVAC systems

3 Phase Power for Commercial and Industrial Applications

The three phase standby generator configuration is essential for facilities with heavy electrical demands.

Three-phase power allows electrical loads to be distributed evenly across three circuits, which improves efficiency and supports larger motors and equipment.

Voltage options include:

• 208V 3-Phase – 167 Amps

• 240V 3-Phase – 145 Amps

• 480V 3-Phase – 73 Amps

This flexibility makes the generator suitable for:

• Office buildings

• Warehouses

• Manufacturing plants

• Agricultural operations

• Hotels and hospitals

Compared to smaller generators, a 48kW standby generator system provides the power capacity needed to run multiple large systems simultaneously.

RDC2 Digital Controller and Intelligent Power Management

A major advantage of the Kohler 48RCLC generator is the RDC2 digital controller, which manages the entire generator system.

The controller continuously monitors generator performance and provides real-time diagnostic data.

Key RDC2 features include:

• Membrane keypad interface

• LED status indicators

• Two-line backlit LCD display

• Programmable exercise schedule

• Diagnostic alerts and maintenance reminders

• Ethernet connectivity for remote monitoring

The digital voltage regulation system maintains ±1% voltage stability, which is critical for electronics and sensitive equipment.

When paired with an automatic transfer switch, the controller also monitors utility power and instantly activates the generator during outages.

Quiet Operation for Commercial Installations

Noise is an important consideration for commercial standby generators. Many municipalities have strict noise regulations, especially for urban installations.

The Kohler 48kW Generator Liquid Cooled 208-240-480V 3 Phase features a fully enclosed aluminum sound enclosure with an integrated silencer.

Noise levels:

• 57 dBA during exercise mode

• 61 dBA during normal operation

To put this into perspective, 60 dBA is roughly the sound level of a normal conversation. This makes the generator suitable for:

• Office complexes

• Residential developments

• Hospitals and medical centers

• Schools and universities

Automatic Power Restoration During Outages

A commercial backup power generator must respond instantly to power failures.

The Kohler 48RCLC automatically restores electricity in seconds using an automatic transfer switch.

The sequence works as follows:

1. Utility power outage occurs

2. Transfer switch signals generator

3. Generator engine starts automatically

4. Electrical load transfers to generator

5. Facility power is restored

When grid power returns, the system safely transfers the load back to utility power and shuts down the generator.

This fully automated process protects operations without requiring manual intervention.

Fuel Flexibility: Natural Gas or Propane

The generator supports both natural gas standby generator and propane standby generator configurations.

Fuel consumption at full load:

Natural Gas

• 875 cubic feet per hour

Propane

• 8.7 gallons per hour

Fuel consumption at half load:

Natural Gas

• 165 cubic feet per hour

Propane

• 4.5 gallons per hour

Using natural gas provides continuous fuel supply in many urban areas, while propane is ideal for remote or off-grid locations.
