At Dale, we have a wide range of canopy generator units that can power everything from an office site to a hospital and large scale facilities.
Our canopy generators are available between output ranges of 20-3,000 kVA and we have flexible options on fuel sources from diesel generators to hybrid generators as well natural gas, HVO (Hydrogenated Vegetable Oil) and hydrogen. We can help you select the best generator to meet your needs and even customise them to your exact requirements.
There are many reasons why a canopy generator is a great option for your backup power supply.
The canopied design provides both weather and security protection allowing you to locate it outside. As a silent generator option, the low noise emission levels also supports outdoor installation and operation enabling you to comply with EC directives.
The close fitting design is a space saving solution for the installation of a generator whilst allowing full access for service and maintenance. All the equipment is integrally fitted inside including the bunded baseframe fuel tank with only power and auxiliary connections required.
Diesel generators are those that are run on diesel, and can typically be divided into two basic parts: a diesel engine and an electrical generator. Diesel generators can be used to provide power to places that are not powered by a power grid or can be used as a backup in case of a power outage.
Natural gas generators use natural gas however, and are used in both emergency and portable generator types. They are one of the most affordable and effective fuels among non-renewable resources for power generation.
LPG (Liquid Petroleum Gas) generators have powerful engines that run smoothly and quietly while providing dependable power when you need it most.
Yes we can, with the range of generators we provide we have the solution to match your need.
Put simply, yes. A generator service and/or UPS service can determine any existing and future power supply problems that could impact equipment performance. Planned and preventative maintenance can extend machine efficiency, assures optimal working conditions and conserves the life span of the equipment. Along with determining when replacements will be needed for a seamless transition, planned and preventative maintenance is a far cheaper solution compared to complete equipment replacement.
Generators are not a source for uninterruptible power therefore a UPS (uninterruptible power supply) bridges the gap between the two. As a critical power provider we can help you decide what is the best solution for your needs.
Electrical generators are pieces of critical power equipment that provide electricity when power from the power grid is unavailable. Interestingly enough, generators don’t actually create electricity. Instead, generators convert mechanical or chemical energy into electrical energy – by capturing the power of motion and turning it into electrical energy by forcing electrons from the external source through an electrical circuit. Once an electrical current has been established, it is directed through copper wires to power external machines, devices, or entire electrical systems.
When it comes to generators, size matters. Undersize a generator and you won’t be able to power your equipment; oversize a generator and you’re wasting money. To correctly size a generator, you should:
Make a list of the items that need to be powered by the generator.
Make a note of the starting and running wattage of the respective items.
Calculate the total power requirements in KVA or KW.
Convert kW to kVA:
For resistive load: Wattage = amperes x volts
For reactive load: Wattage = (amperes x volts) x load factor
Define your running requirements.
Analyse site conditions and access.
Our team can help with correct sizing to ensure your generator will meet both power and site requirements.
Nearly all electronic and electrical equipment, regardless of how well-designed and built it is, will eventually break down unless it is maintained according to the manufacturer’s instructions. Wear and tear is common with electrical equipment, but it has severe consequences for UPS systems and generators, where financial, reputation and potentially life-threatening damage comes into play. It is highly recommended that as a minimum you service your power systems annually in order to maintain its working lifecycle. Our service contracts include everything from AC maintenance, DC maintenance and generator maintenance through to analogue metering, intelligent monitoring, remote monitoring and spare parts, as well as callouts, minor fault fixes and access to our customer portal, where you can access management information reports and other key details on your power supply systems.
Without proper maintenance, generators can fall prey to failures and power outages. Generator manufacturers generally recommend that a generator should be serviced after the first year of installation and on an annual basis there on after. We also suggest carrying out regular visual inspections to keep on top of any faults within your generator that may require maintenance sooner than anticipated.
Factors that may result in more frequent maintenance include:
Exposure to extreme temperatures and weather can damage components of the generator.
Airborne contaminants such as dust and sand may infiltrate the generator, causing damage to its internal components.
Excess usage: Most diesel generators are designed to provide backup power. Should a standby generator be used for prime power, care should be taken to ensure the generator is inspected frequently and only used for as long as it is required.
Lack of usage: Similarly, if a generator is left dormant longer than expected, engine exercise should be carried out to avoid battery failure.
As batteries go unused, with no charging schedule, their battery life will decrease. When it comes to the self-discharge characteristics of lead-acid batteries for example, it is important that they are charged after 6-10 months of battery storage. Otherwise, permanent loss of capacity will occur between 18-30 months.
A petrol generator is an alternative to diesel but typically used only for short periods. Greener alternatives include natural gas. These generators rely on underground access to natural gas. Another option is propane which is generally chosen when natural gas isn’t available.
Once the generator has been installed successfully, it will require further attention before the system will operate as intended. ‘Commissioning’ refers to the tests that are carried out to ensure that the generator works as intended. Certain components need to be completed before the generator is ready for commissioning. Upon completion, each component needs to be verified to ensure the generator is fully operational to achieve optimum performance.
Knowing exactly which parts are needed is of vital importance to successfully repairing any damaged or faulty generators. First, you must identify which part needs replacing, then you need to find the corresponding part for the exact make and model of your generator. Our dedicated team use a parts identification system and an advanced ordering system to get you the right part when you need it most.
Commissioning generally means booting up the generator system, which needs to be tested to make sure that it works as it was designed to. Generators feature complex mechanics and there are certain components that have to be checked prior to the boot-up in order for the system to be ready for commissioning. Once all components have been verified, typically the boot-up should run smoothly and will not require additional trips.
The UK electricity system has experienced high levels of grid resilience historically – offering a high degree of confidence to businesses and consumers that power will be available 24 hours a day, 7 days a week, 365 days per year. However, we must be able to respond to the more severe, less frequent events to ensure power supplies are maintained or restored quickly following such an event. Therefore, grid resilience is ‘the ability to withstand and reduce the magnitude and/or duration of disruptive events, which includes the capability to anticipate, absorb, adapt to, and/or rapidly recover from such events‘.
Load bank testing is typically carried out during preventive maintenance, and is a way of validating the correct operational performance and battery autonomy of your generator. Testing this under load conditions, a load test can determine battery condition and when they are approaching their end of working life, not holding a charge or are about to fail. This allows a load bank tester to replace them in advance of breakdown or failure, ensuring that critical power supply is always available.
A load bank test will provide timely identification of problems with the generator and an indication of remedial actions that should be taken. In the case of a standby generator, a load bank test will indicate the engine’s ability to provide the required power; the alternator’s capability to provide the required voltage stability; stable frequency; efficiency of control systems under varying conditions of load; performance of the whole system; oil and fuel pressure. It will also help remove deposits from pistons, engine castings and exhausts, identify potential weaknesses, record results and any work that needs to be done.
