80The internet and the numerous quality office stationery suppliers that can now be found online means that it is easier than ever before for businesses to find what they need for the office environment, ranging from printer cartridges right through to reams of printer paper, pens, computer parts, and many other accessories and items.

However, buying online does not come without its risks. It is very easy to make mistakes when buying certain items that have to have certain specifications, and it is also hard to ascertain the quality of items before you buy. In addition to this, it is often difficult to know who is a reputable supplier before you actually place your order.

With this in mind, it is important to keep a few things in mind when you buy certain stationery products. Some of the products that you should be careful about buying online are printer cartridges. The reason for this is that printer cartridges can be particularly costly, and certain aspects such as quality and price can have a significant impact on your business.

Firstly, you will need to make sure that your cartridges are of the highest quality possible to meet your needs and stay within your budget. The quality of a new cartridge will depend on a number of things. It can refer to the colour and the appearance of ink as it is printed on a page, or it can indeed refer to its effect on your printer warranty.

Therefore, when you invest in this particular stationery item, it is important to make sure that the quality is good enough for you to spend your budget. There is a simple and easy way to do this, and that is by going straight to your printer manufacturer and asking for they advice on the best product available.

In the majority of cases, a printer company will advise you to buy their own brand name products. Indeed, this is often the way to get high quality and prevent the voiding of any warranty that you may have on your printer. With that said, these can be expensive, and it may be worth finding a viable and cost-effective alternative that is also of quality.

In this case, it is necessary to find an office stationery supplier that is able to advise you on the best products to buy. To do this, look for a retailer that specialises in delivering high quality stationery products for a business and private customers. They will often be likely to advise you on the variety of products that they have in stock and whether they are suitable or not for your needs.

Secondly, bear in mind that you can often make a mistake when ordering your printer cartridges. Many people can easily become confused with the various printer models, cartridge sizes and printer cartridge colours; it is not unheard of to order the wrong products on a surprisingly frequent basis.

This reason, check that the retailer that you are buying from is able to offer you a good refund and return process in the case that you make an error. This is vitally important, as mistakes are quite common. If you are able to know that you can return and exchange your items hassle-free, you will not lose money and you will not have to deal with the stress of dealing with a difficult supplier.

Thirdly and finally, make sure that you have a good printer cartridge specialist on hand should you run into any issues. Often, your printer manufacturer will be able to deliver this kind of support and advice service to you. However, you may find that your stationery retailer will be able to give you ample advice and help should you need it.

There are several important points to consider, from selecting the right products right through to how to get the most use out of your cartridge. Importantly, using a good office stationery specialist will help you give the right balance between quality and cost effectiveness. In addition to this, they will often be able to give you plenty of free advice as a valued customer.

marThere are many different types of fan guard, made from a range of materials including metal and plastic. As fans are essential for cooling electronics, many people who need to purchase them can rightly wonder which the best type to buy for their needs is. Each different type of guard has its advantages and disadvantages, which will be explored below.

One of the materials of choice for this type of accessories is metal, and aluminium is a very popular choice for many people. There are several reasons for this, including that it is often made into a special mesh which offers some of the best protection for electronic fans.

Aluminium fan filter units actually allow for high levels of air passage, as well as catching contaminants and shielding EMI interferences. These are often available in numerous sizes as well, which is ideal for those using different size fans for their equipment.

Aluminium is one of the hardest wearing materials, why it is often used in this kind of mesh guard. Mesh, due to its fine construction, could be easily damaged if made from another material. Due to the properties of aluminium this is not the case with mesh guards, as the metal is very hard to pierce or break.

There are also perforated metal fan guards available too, which offer excellent cooling and a great deal of protection. This protection is possible as the guard itself is a sheet of metal with several holes in it to allow the passage of air. The metal acts as a shield which prevents the fan from becoming damaged by impact.

Indeed, both perforated and mesh fan guards are very good at providing a great deal of protection to the fan. For certain applications, where a great deal of protection is required, these two might be the best choice.

One of the most common other metal guards on the market is the coiled wire fan guard. This can be made from aluminium and various other durable metals. These offer a particular advantage over the other guards mentioned earlier. There are also some disadvantages that need to be taken into consideration by the customer.

A coiled wire fan guard basically consists of a long piece of metal twisted round in a coil which is then used as protection for certain fans, commonly including the fan tray assembly in a computer or laptop. In the fan tray assembly these tiny metal coil fan guards are ideal for protecting the small fans inside.

Unlike larger mesh or perforated fan guards, these coiled wire fan guards are adaptable and appropriate for numerous sizes of fan, from tiny to very large. Often these types of wire fan guards come in different shapes too, which again differentiates them from the uniformity of mesh or perforated guards.

These also have the advantage that they can increase air flow by up to 50%, meaning that they are ideal for cooling electronics and other equipment much more efficiently than other options.

Finally there is the plastic fan guard, which is common choice for many different types of equipment and electronics. This choice is particularly popular with those who require a less expensive option as a fan guard. Plastic is generally inexpensive, especially when compared with its metal counterparts.

Traditionally, plastic was less reliable as a material than metal, and much easier to snap or break. However, recent options on the market have been reinforced with fibreglass for added strength. This means that plastic fan guards can now live up to their metal versions, and prove just as reliable in a number of scenarios.

These are just some of the main types of fan guard that are widely available on the market. From coiled wire fan guards that are commonly used in a typical fan tray assembly to reinforced plastic ones, there is something for every need and requirement.

37Do you have the habit of testing your electrical system or Unit? Then you need to opt for professional service which will help you to meet your requirements.

The load banks will help you to learn everything about the performance of an electrical unit or system. They are mainly used for testing the electrical power outputs on gas turbines, diesel generators and the UPS system as well as conducting maintenance and commissioning. Such testing should be a regular part of the generator maintenance to avoid mechanical failure caused by the engine and other components when the generator is used in the power outrage. It also prevents the wet stacking and carbon build up.


These equipments apply a stable, controllable electrical load on the generator. It can be permanent or portable and can accommodate AC or DC ranging from a few kilowatts to multiple megawatts. Most units have an internal fan that cools the resistance elements and discharges the high-temperature air from the system. Hence, it is crucial to accurately position them away from combustible materials in order to ensure that it is operated in a open environment and protect the generator from overheating.

Types of testing

The testing has two separate methods. These are reactive and resistive in nature. Resistive is the most common method of field testing because it encompasses the full KW rating of the generator and the engine system such as cooling exhaust and fuel delivery system. Reactive testing is mainly done in the factories in order to test KVA ratings.

Testing Schedules

The generators must have the capacity to go from a cold start to a position of full load in a matter of seconds. Testing at this level keeps the part lubricated and prevents oxidation from the electrical contacts. It also enables the reliable engine starting. The annual unit should always perform at 100% level for a minimum of one hour. This test should be carried out by stepping up the load at certain intervals.

A mobile version of these units can be rented from a generator service and trailed to the site for connecting to the generator. They are manufactured with additional switches that help you carry the instrument from one place to other in order to test. The incremental switches help the machine to be ramped up with the generator and thus the testing is done.

The procedures for connecting them should be well thought off to mitigate the problems in case of failure of the regular electric utility source during the exercise. The output cables and generators should never get disconnected while the test is going on.

To conduct the test, these units should be parallel with the building so that any kind of reconnection is not required. In some critical cases, portable units and the generator is kept side by side in order to do the test.

In conclusion, it can be said that these testing modules will give enough efficiency to the generator in order to make them run smoothly for a longer period of time.
