Filtration Systems (Van Mounted and Portable)

17 April 2014

Streamline® water filtration systems are designed to be used for window cleaning, bus shelter cleaning, solar panel cleaning, and boat cleaning etc. where a spot-free finish is essential.

To achieve this, the system has a series of filters to produce pure water with a reading of 0ppm. However, the filters require maintenance from time to time to ensure optimum efficiency.

All van-mounted systems are fitted in-house at Varitech Systems. This ensures every system is bespoke; made and fitted to customers’ specifications. If you are in a soft water area (<150) you would only require a Resin Bead System, and if you are in a hard water are you would require a full Reverse Osmosis System.

We are concerned for your safety…

  • We always recommend you take the option of having a baffled tank with your system, rather than the standard upright or flat. ‘Baffles’ are areas within your tank that separate the load and prevent uncontrolled movement of the water.
  • We always enclose the tank either in a stainless steel frame or with two plates bolted to the floor of the van. Ratchet straps are never used to secure the tank.
  • Each litre of water weighs a kilogram, so a 1000 litre system would be a tonne of water - we have a legal obligation to ensure that your system is fitted securely.

With experienced engineers fitting every system and full technical back-up and after-sales service, you can be assured that you are in safe hands. While we provide you with a tailor-made system to suit your demand, you can still keep within your budget and be assured that your system is for life.

Ecostream™ Van Systems

The new and innovative range of Streamline® Ecostream™ systems are designed especially for the price-conscious window cleaner and cleaning contractor.

These are great starter options suitable for a variety of vehicles with 250-litre, 400-litre, 680-litre and 704-litre tank options. Due to their compact size and the fact most of the components are housed within the tank footprint, these systems take up the least amount of room possible, allowing space for other cleaning equipment, provided the payload of the van allows for the total weight of the system when filled with water. Each system comes complete with pump, controller and is assembled, ready to be installed. Options to add a battery and a robust steel hose reel capable of housing 100-metres of hose are available to be included in the tank design.

Trailer Systems

Trailer systems are extremely versatile and allow you to free up the load area in your van or even run your cleaning operation with a car. Options include simple de-ionising resin filter systems, or mini reverse osmosis filter systems for use in hard water areas, fitted and ready to go.

For guideline use only

·The resin filter vessel on the Streambox holds 6Ltr of resin - meaning you can fill it 4 times from a 25Ltr bag of resin.

·Any reading up to 7 ppm is an acceptable level of water purity for pole fed window cleaning.

·If your tap water is at 100 ppm water quality - the resin filter vessel on the Streambox will purify 2000Ltrs of water before it needs to be re-filled. This is enough pure-water to clean the windows on approximately 80 x 3 bedroom houses.

·If your tap water is at 200 ppm water quality - the resin filter vessel on the Streambox will purify 1000Ltrs of water before it needs to be re-filled. This is enough to clean the windows on approximately 40 x 3 bedroom houses.

·Remember - you can fill the resin filter vessel 4 times over, from one 25 Ltr bag of resin!

How to change the resin in the resin filter vessel

·Remove the black resin filter from the trolley and unscrew to top black head.

·Draw the riser tube from the resin contents.

·Dispose of the spent resin in a responsible manner.

·It is not harmful to the environment.

·Once the empty vessel has been flushed out with water, refill the filter housing with new resin leaving an air gap of approximately 2”.

·Carefully push the riser into the resin.

·Shake the filter housing in order to allow the riser to ‘bottom’.

·Clean the sealing edge of the housing before securing the top.
