South Shore Generator - KD Industrial Generator Series Expands in Wareham, MA

When the KD Series large diesel industrial generators were unveiled in October of 2016, KOHLER and KOHLER-SDMO also announced the planned expansion for the new line, which would eventually grow to encompass generators as large as 4200kVA (50Hz) and 4000kW (60Hz). Today, based on strong worldwide response to the initially-launched models – utilizing KOHLER’s own diesel engines ranging from 800kVA/800kW to 2800kVA/2500kW – KOHLER and KOHLER-SDMO are proud to officially expand the KD Series with the rollout of several new generators ranging up to 3500kVA/3250kW.

The first wave of KD Series generators really resonated with key influencers in the data center, healthcare, telecommunications and water-treatment segments around the world. Now KOHLER can providing these users – and many others – with additional KOHLER-powered options that will deliver a similar mix of durability, fuel efficiency, and the many other benefits that have helped the KD Series to stand out in this competitive global category.

The newest KD Series diesel industrial generators are powered by two new compact and powerful KOHLER V16 engine models. The KD36V16 is a 16-cylinder engine with 36-liter displacement, which will power the 60Hz KD1250 and KD1350 as well as the 50Hz KD1250, KD1400, and KD1500. The other new engine is the KD83V16, a 16-cylinder model with 83-liter displacement, which will power the 60Hz KD2800, KD3000, and KD3250 as well as the 50Hz KD3100, KD3300, and KD3500. Both engine models deliver highly efficient and dependable performance and feature a modular design for optimal serviceability.

KD Series – Global Success Stories

The KD Series large diesel industrial generators have been selected by key decision makers in numerous industries worldwide, including the data center and healthcare segments. A few initial success stories are highlighted below.

Data Centers:

22 KD1600 generators were selected for a large data center in Ashburn, Virginia (USA). The complex will encompass six buildings with more than 245,000 square feet and 16 megawatts of critical IT load.

11 KD1800 generators were selected by a UK-based data center. The center is owned by a Japanese telecom company, which selected the KD Series based on the low emissions of the new line.

Healthcare:

Two KD1800 generators were selected to provide backup power to a major hospital in France. The generators are placed in ISO20 Super Silent containers and will ensure critical systems in the hospital’s many operating rooms maintain power during unplanned outages.

Industrial Generator Reliability in Winter Depends on Regular Maintenance

Joseph Coupal - Monday, January 08, 2018

Throughout the year, inclement weather threatens the stability of power grids across the country. Every time an outage occurs, countless power outages threaten an organizations data, employee safety and customer loyalty.

With hurricane season behind us, it’s time to focus on winter storms. Ensuring reliable generator operation throughout the winter months requires routine maintenance. This is especially important given the extreme low temperatures in which the generator will be required to operate. Maintenance can be performed by your own trained technicians or as part of a maintenance contract.

Fuel Reliability

If yours is a diesel-fueled generator — and unless you’ve experienced power outages so frequent and severe as to consume an entire tank of fuel — the beginning of the new year is an excellent time to perform fuel maintenance. Diesel fuel tends to degrade over time, and will require filtering and polishing to eliminate moisture and contaminants that, if introduced to the engine, could at a minimum reduce performance but run a real risk of causing engine damage. Diesel fuel maintenance is especially important in the winter, when water in the fuel can freeze inside fuel lines and prevent the generator from starting.

Inspecting Spark Plugs

While gaseous-fueled generators have the benefit of operating on a fuel that is largely unaffected by extreme temperatures, one thing that can impede successful gaseous-fueled generator operation is bad spark plugs. Pitted and fouled spark plugs could cause the engine to misfire repeatedly or fail to start entirely. To avoid increased exhaust emissions and improve the generator’s ability to start in the cold, the spark plugs should inspected — and changed, if necessary — at least once each winter season.

The Engine’s Electrical System

Generators can only produce power if they receive power — in the form of DC voltage coming from the starting batteries. Dead batteries mean a dead generator set. In cold weather, batteries run the risk of losing their charge. They should be inspected for damage, and a load tester can help determine if the battery is having difficulty maintaining a charge. Make sure battery fluid levels are properly maintained, and ensure that cables are securely fastened to the terminals and that both are clean.

Changing Engine Coolant

Coolant prevents the development of rust deposits, keeps the generator’s water pump well-lubricated and helps remove contaminants from the gen-set’s system. Maintaining engine coolant keeps the generator prepared for harsh winter weather and helps ensure its long-term performance. The coolant supply should be flushed and changed at least once per year or after every 100 hours of operation — whichever comes first.

Inspecting and Changing Filters

During warmer months, dust, dirt and debris can invade your generator. Luckily, oil and air filters are designed to serve as the engine’s first line of defense against these harmful contaminants. The generator’s oil filter — or filters — should be changed at least once per year to keep debris out of the engine and prevent potential damage. The beginning of the new year is an excellent time to change the oil and filter.

Load Bank Testing

While a generator may start flawlessly, there’s no way of knowing if it’s actually producing the power it should unless it is periodically connected to a load bank. Load banks allow the generator to run under load in a simulated outage situation. They test the generator to see if it will perform as intended during a real power outage. Load bank testing should be performed annually, and once again, the winter season is an excellent time to get that annual testing out of the way.

Cold Weather Generator Operation

Joseph Coupal - Tuesday, January 02, 2018

Diesel generators are notoriously problematic during cold weather. Not only does diesel fuel become unstable in cold temperatures but when the engine block and heads are cold, they absorb the heat of the compression required to ignite diesel fuel.

When generators used for standby or continuous power will be operated at 32°F (0°C) or below – especially for extended periods of time – operators must take precautions to ensure the generator will start reliably, get to the desired load quickly, and continue to run without incident and unnecessary stress and wear on the engine.

Although fuel additives and other intermittent measures have long been common for generators, there is also a wide variety of purpose-built equipment that protects generators and their components against the cold. Some specialized add-ons keep the engine block warm; others keep coldsensitive equipment such as batteries and control boxes operating at the optimal temperature. This equipment is especially important where generators are being used in remote environments without any oversight by technicians or other company staff.

This blog looks at some of the equipment that can help companies protect their generator investments and ensure reliable startup and operation. It also offers a few pointers on selecting a provider to source generators and engines that are properly equipped for extremely cold weather use.

Battery warmers

Battery warmers enclose generator batteries in a thermal wrap, keeping the battery at a constant 80°F (27°C), the optimal temperature for maximum cold-cranking amps. Battery warmers should have durable, fire-retardant covers that resist oils and acids.

Thermostats, if available, can eliminate battery damage from possible overheating and subsequent acid spillage. Battery warmers prolong battery life and can boost cranking power by as much as 75 percent.

Block heaters

Block heaters, which are installed on the coolant circuit, keep the engine’s coolant warm enough that the unit is able to start immediately and attain/maintain the required engine load. They are generally powered by an external power source rather than the generator engine itself.

Hydronic coolant heaters

Hydronic coolant heaters gradually raise the temperature of the engine’s coolant, assuring even heating of the engine block. They enable generators to have warm starts, which reduce engine stress and wear, and reduce demand on the battery. Hydronic coolant heaters work independently of the engine, yet they tap into the fuel and power supplies of the engine. This approach eliminates the need for an external power or fuel source, which enables them to operate anywhere a generator could be located.

Control panel box heaters

For enclosed generators, cold weather operation brings another peril: condensation due to the differential between the external temperature and the temperature inside a heated enclosure.

These heaters keep the control box at an even temperature, preventing the condensation that can damage sensitive electronic parts.

Louvres

Louvres (also called dampers or shutters) open and close based on a specific trigger, eliminating both overcooling and overheating by regulating the amount of ambient airflow through the generator engine’s radiator.

Louvres can be thermostat activated, in which case a thermostat is installed inside the generator enclosure and an electronic switch triggers their operation when temperatures rise above a preset threshold. Electronic louvres such as these should always include electronic stall protection.

Louvres can also be hydraulic, being driven directly by the temperature of the engine’s coolant. Coolant-driven louvres open gradually, allowing the engine to cool effectively but preventing a sudden influx of cold air that could cause the temperature inside the generator enclosure to drop precipitously.

Hydraulic louvres are a preferred option in extremely cold climates because they do not contain sensitive electronic parts that are prone to seizing and failing in cold weather. Both types of louvres should also be able to prevent snow intrusion into the unit.

Snow hoods

Snow hoods are specialized coverings designed to prevent snow from accumulating inside the generator enclosure. Some manufacturers can relocate the generator’s air exhaust when they install snow hood kits, further preventing snow intrusion into the exhaust pipe without restricting air flow.

Final thoughts

When a generator is needed to supply power, there may not be much time for warm-up. A cold pack (winter pack) is a proven solution for ensuring generators can start without a long warm-up time and stay running dependably at temperatures ranging from 32°F to -50°F (0°C to -46°C). Depending on the situation and condition of the generator itself, this equipment can reduce the incidence of generator failure in cold conditions by 50 percent or more.
