HIGH FLOW TANKLESS RO SYSTEM

Suitable For 3,000 Litres Per Day

The High Flow Tankless RO system is a versatile solution for producing purified water on demand, measuring 95cm tall, 40cm wide and 53cm deep. Featuring two integrated 500GPD booster pumps with high and low pressure switches, allowing the system to run effectively with feed pressures as low as 2 bar. This system is a great choice for direct, high flow rate applications where purified water is required intermittently and on demand (such as for the cutting of spirits, ice-making, car detailing or food and beverage).

The pressure gauge mounted on the frame gives a visual indication of the feed pressure to the RO membranes downstream of the two pre-filters – allowing for easy monitoring of pre-filter lifespan. Thanks to the dual booster pump and membrane configuration, the system boasts not only high flow rates but also a desirable rejection rate of 95-99% on average.

Why Use A Direct Flow RO System?
This system is a great alternative to purchasing purified water, with low maintenance and operating costs contributing to a short payback time. Offering a flow rate of 125 litres per hour this RO accommodates many applications without a bulky water-storage tank which can otherwise take up valuable space, suitable for a direct connection to the feed of a process, machine or appliance.

What Maintenance Is Required?
The pre-filters and carbon post-filter should be changed every six months if the system is in daily use. The RO membranes should be replaced every 2-3 years in soft water areas, or every 1-2 years in hard water areas. For customers in hard water areas, pre-treatment is recommended to improve membrane lifespan and reduce operating costs.

Why Choose Our High Flow Tankless RO System?

  • Visible pressure gauge showing feed pressure to membrane
  • Suitable for a direct feed to a process or appliance
  • Excellent average rejection rate of 95-99%
  • High capacity industry-standard pre-filters
  • Easy to install and maintain solution

Very pleased with the service. There was an issue with the water softener I ordered initially, but then following communications made the replacement process quite pleasant. Happily recommend this company. Thanks to Becky for working with me. Great follow up support 😊😊😊

First time using this company and product and i wasnt dissappointed. Communication was easy and quick resulted in an easy order and now having fitted the filter i can say its a great product easy to install and appears good quality apart from the four mild steel bracket screws stainless would have been better considering the environment these are fitted. All in all, very pleased and would highly recommend .

Excellent local company and genuinely lovely people to deal with. Really helpful and knowledgeable, with great advice about my water softener and the correct salt to use. They even gave me some resin cleaner at no charge, which was a very kind gesture. Fantastic friendly service and I’ll definitely be returning for my salt in future. Highly recommended.

Excellent service. Product proved my softener was not working as it should. I fully serviced it and cleaned with Resin Clean returned to service and it is now working as designed. Very pleased.

If you're thinking about a water softener then i HIGHLY recommend Ultra Soft Water Softeners Ltd. Great softeners and exceptional customer service. The water softener I bought needed some adjustments with the installation setup where I supported throughout. The customer service is honestly next level. I had countless calls with Becky Gillett, the Sales Manager, over a period of months to get to the bottom of it. She was incredibly patient with me, staying on the phone and doing video calls to walk me through the programming instructions step-by-step while I changed the settings and ensured all was installed correctly. All the staff here have been great, but Becky really stuck with me from start to finish to make sure it was sorted and working well. It runs like a dream now. HIGHLY recommend them!

Easy to order, quick delivery, good communication. Resclean worked a treat; one treatment cycle and soft water is back again from our 12 yr old softener!
