All of our rental equipment can be delivered with accessories, which means that we can offer a complete and hassle-free work solution at the push of a button. The most common accessories are listed below, but please do contact us with any other requirements as we have a considerable stock of tailored accessories from past projects that may fit your process as well.
Piping, hoses and air valves
We offer piping suitable for low and medium-pressure operation. To allow big flows at low speed (thereby reducing sound), we have large-diameter piping of up to DN500 in our fleet.
We have both plate piping and special RVS316 pipes. The pipework is modular and comes in standardised lengths and with flanges to connect to elbows, t-pieces, valves and reducers (DN25 to DN500, ANSI 4” up to 12”).
In addition, we have RVS316 flexible hoses in various diameters up to DN250, as well as flexible hoses DN080 for small flows and for plant-air compressors.
We support our clients with electrical power solutions by supplying power cables that are able to power single compressors of up to 355 kW. The power cables are modular and, with the use of connecting boxes, can be supplied in any length you require.
We offer an IT transformer 630 kVA for outdoor installation and TN transformer up to 1000 kVA for indoor installation for low voltage (690 V). For medium voltage we apply multi-voltage transformers with field dividers up to 3200 kVA.
Besides power provision, we also support the integration of our rental equipment into your process control system, for which we provide tailored solutions (e.g. Profibus, 4 to 20 mA, potential free contacts).
Diesel powered generators
Although we are fully focused on electrically-driven equipment, we can arrange diesel powered generator sets from 30 to 2,000 kVA with fuel tanks and including fuel management, which we provide in close cooperation with a select group of trusted suppliers.
Even renting diesel powered generators from us makes good economic sense, as we will select the right generator to match your process demand. As with the blowers, the compressors have variable speed drive power and therefore fuel economy is optimised.
Do bear in mind though that diesel fuel costs more than electricity, and might work out to be the largest cost element of the entire rental, generally being triple the cost per kW compared with an electrical power supply. That said, with diesel powered generators their operation is fully under your control, regardless of the load of the local power grid.
Cooling, water-air separation
For many applications, a little heating of the air is useful and in some cases even necessary for the process activation. However, whenever the temperature needs to be brought down, for instance with plastics or food products, we offer the option of air-air coolers, which cool air down to approximately 10 °C above the ambient temperature.
If you can provide cooling water (or if we can extract water from the soil or we have a cooling skid) we can apply water-air coolers to cool down to any temperature required.
Behind the coolers, we can provide modular water-air separators so that condensate (even if in large volumes) can be separated.
Aerzen’s roots lie in the supply of blowers and turbo blowers for delivering oxygen into WWT plants, surface water and/or aerobic processes. In addition to wiring, piping and blowers, Aerzen Rental also supplies robust (well suited for rental) fine coarse bubble aeration grids.
Our aeration grids can replace any type of aerating system, including surface aerators, offering the highest oxygen transfer rate. When the bottoms of the tanks are not level, or where there are obstructions, we also offer floating aeration grids. For catching sediment or plastic waste in rivers we also offer aeration tubes which can be placed across a channel
Plant air dryers
To support our clients with their oil-free plant air systems, we offer dryers. Our dryers are used for plant/process air but can also be used in sandblasting and to evacuate water from tanks or pipes. Our dryers are mostly robust cold regenerating dryers, hence we are actively including zero loss dryers in our fleet. Do call on our expertise so that we can fully meet your requirements; we can offer solutions when even higher dew points up to -70°C are required.
