Nirosoft’s all-in-one desalination solutions are pre-engineered to get up and running fast. And they depend on Danfoss iSave® ERD technology – with unsurpassed isobaric efficiency, simple construction and extreme reliability – to deliver no matter what the water temperature, salinity or lead-time.
Pre-engineer it to be flexible enough to accommodate a wide variety of desalination conditions. And deliver at a good price.
Nirosoft saw a market opportunity and went for it. The Israeli company specializes in tailor-made solutions that include everything from engineering and hardware to installation and BOT contracts. An experienced system integrator, they were familiar with all the major suppliers of components for RO plants. And they knew how difficult it was to get a high-quality containerized plant up and running fast.
“We wanted to create a plug-and-play unit that is robust enough for very low maintenance, but at a price customers can afford to pay,” explains Michael Tramer, global VP of sales and marketing. “Until now, the problem has been to balance good delivery time with good price. It used to take anywhere from five to nine months to get the kind of components we need at a decent price from our key suppliers. If you wanted them faster, then you had to pay sometimes a lot more.”
Nirosoft developed its new NIROBOX™ as a plug-and-play membrane based desalination plant that contains everything it needs inside a 40-foot container.
“Basically, the NIROBOX™ is pre-engineered to hit the ground running,” says Tramer. “All you need to do is connect the electricity, inlet and outlet pipes, and it’s ready to go”.
We are also able to deliver on a very tight schedule – just a few months rather than up to nine months as we used to. Everycomponent has been carefully selected for performance and reliability – as well as delivery time.” NIROBOXes can be configuredto produce anywhere from 100 – 1,000 m3 per day.
“We knew from the start that Danfoss’ iSave® ERD would be at the heart of the containerized plant,” says Tramer. “There is just no other ERD that delivers the same combination of energy saving, low maintenance and simplicity for both installation andoperation. Plus, Danfoss is able to supply both their iSave® and APP high-pressure pumps at very decent lead times.”
“Other suppliers do provide ERDs with isobaric chambers,” continues Tramer, “but their constructions are much morecomplicated, take a lot more space to install and are more susceptible to break down.”Nirobox™ − 40 foot container built with an iSave® ERD and APP pump. The container can also be built with more iSave® ERDs and APP pumps in parallel.
Nirosoft recently installed its first NIROBOX™ in the remote fishing community of La Chanavayita on Chile’s Pacific coast. The plant comprises three iSave® 21 ERDs and APP pumps in three parallel trains. Each train produces 15 m3 per hour, and the entire plant has a capacity of 1,000 m3/day.
“We’re really pleased with the support Danfoss has given for this project,” says Tramer. “We’ve proven the NIROBOX™ concept with the La Chanavayita plant, and now we’re ready to roll it out. We don’t think there is any other solution that can provide such reliable SWRO so quickly – anywhere. And we can’t wait for Danfoss to launch the iSave® 64 that they’ve told us is in the works.”
The range of high-pressure APP pumps is optimized for both landbased, off-shore and marine sea water reverse osmosis applications. Available with or without motor.
With a 3-in-1 design that integrates highly effective isobaric pressure exchangers with positive displacement booster pumps and electrical motors, active iSave® ERDs deliver big energy savings in small spaces. Covering train sizes from 200-3,000 m3/day
