The all new Ecomax range are more powerful, even more efficient and therefore even more frugal in terms of running costs than the Aquamax range they replace, now using a third less power.  Like all previous Aquamax models, can still be installed as a wet or dry pump, and with adjustable inlet flow when used submersible.   Now manufactured with a completely frost proof casing and pump stand.  Supplied with 10 metres cable and 3 year guarantee. (can be extended to 5 year)   Without doubt THE  best wet or dry pump range available today and extremely reliable. Ideal for main filter pumps and skimmers - only suitable for venturis or waterfalls in larger sizes. All models are now supplied complete with frost proof impellor housing so where applicable can be left in pond all winter.  Ecomax have been developed with low running costs in mind and are now even lower wattage than before - 8000 litres per hour for 80m watts - quite incredible!

Optimax Range.

The Optimax range are without doubt the most efficient and frugal pumps on the market today and are fantastically cheap to run.  With all new electronically controlled electric motors and clever impellor design, nothing comes even close in terms of providing efficiency in terms of moving water. 2,200 gallons per hour for 65 watts !! Staggering performance and with all the usual Oase benefits, 5 year warranty, very quiet and reliable.  Supplied with 2" inlet and outlet, 10 metres of cable, stainless steel strainer and demountable base.   Can be installed wet or dry.  Best installed as filter pumps when using 2" return piping and little or no head.

The Neptune range from Oase are high performance pumps which like the Aquamax range can be used wet or dry, i.e. they can be used in pond or dry in the filter chamber.  Neptune are higher pressure pumps than Aquamax, and will therefore have better head characteristics so are better suited for applications such as waterfalls, and other water features where higher pressure is required to maintain flow rates.  Like Aquamax, they are supplied with 10m power cable and a standard 3 year warranty which can be extended to 5 years.  Supplied complete with stainless steel inlet strainer and adjustable inlet valve for used in all wet applications. 4000 and 6000 models feature 1" inlet and 1.5" outlet. 9000 and 12000 models feature 1.5" inlet and outlet. Also supplied with clip on stand for floor mounting with dry applications.  All models are now supplied complete with frost proof impellor housing so where applicable can be left in pond all winter.

Yamitsu UVs are probably the best selling UV systems in the world and have been in production since 1990. They are manufactured from UV stabilised materials and are rugged and reliable, They are now also one of the only UV systems available which are fully CE compliant for electrical safety, featuring for example, safety clamps holding the UV tube in place to prevent accidental removal.  They are fully electronically controlled for reliability and long life - and importantly to ensure low running costs.  Did you know that the average UV system using 'conventional' electro mechanical control gear consumes over four times as much electricity as an electronic model? So a conventional 30 watt UV can actually consume as much as 160 watts of power!  They are easy to install with all models featuring glued hose tail connections for flexible pipe work, and 1.5" inlet/outlet ports ready to glue to solid pipe work connections too. They also come complete with mounting clamps.  All models are easily serviced and control gear can be replaced if required.  Still the most cost effective UV systems available. 

TMC Pro Clear UV systems

TMC UV equipment is tough and reliable, is easy to install with all models featuring threaded connections and larger models featuring a choice of inlet and outlet positions to maximise flexibility of installation . All models are easily serviced and both starters and ballast electronics can be easily replaced in component form.  Come complete with hose tails for flexible pipe work connections and 1.5" female threaded inlet and outlet ports for direct connection to solid pipe work fittings. Also complete with mounting brackets

When calculating the size of UV required, start on the basis that 10watts is required for every 1000 gallons

Cloverleaf have launched a completely new range of stainless steel UVs which, for the first time,  provide high power UV systems at sensible prices. These UVs are more powerful than a conventional UV of a similar wattage, and therefore provide not only a better kill rate for Algae cells, but manage higher pond gallonages . These units can be supplied in a range of wattages, up to 288 watt as standard and special larger commercial models can be made to order - please ask for details.  All models feature 1.5" inlet and exit ports, and are made to accept either solvent weld waste or pressure pipe fittings. In this range of UVs the electronic control gear is mounted at the end of each bulb, so when a bulb is replaced, the control gear is also replaced.  Whilst the bulbs are more expensive than with conventional units, efficiency of these units is maintained at close to 100% owing to the integrated control gear technology. This also means that a 48 watt UV can simply be upgraded to a 72 watt unit for example, simply by changing bulbs.

These all new UV sterilisers use a completely different wavelength of UV light, i.e. 30,000 µ/sec/cm² which effectively kills a wide range of organisms in pond water, especially Aeromonas and Pseudomonas bacteria and many types of virus.  The units also feature special bulbs which have an effective life of over 1 year or 9000 hours and use very little electricity making them extraordinarily cost effective.

Exclusive features of this range include a 316 Stainless Steel housing that allows for 360° rotation of the inlet and outlet unions for ease of installation,  simple design of the lamp chamber that makes bulb changing a simple job that can be accomplished by even the least mechanically minded person in 2-3 minutes.  Another key exclusive features not commonly found in similar units is the inclusion of unions at each end of the Stainless Steel housing, which allows for 360° rotation of both inlet and outlet ends for universal piping options as well as the total disassembly of  the Stainless Steel housing to facilitate cleaning of the quartz tube, should it be necessary.  Units can be installed indoors or outdoors, in a horizontal or vertical position, with mounting simplified by utilizing the Stainless Steel mounting legs supplied.
