Modular systeMs for efficient reverse osMosis technology

our large range of standard reverse osmosis equipment covers permeate rates from 80 to 30,000 litres per hour. Please contact us if you require a higher rate.

Herco reverse osmosis units are outstanding

the specific design of the different series offers made-to-measure equipment for every application:- uo/uo-d series 120 – 500 l/h: ro 524 or ro digital controller, as combi c (with simplex softener) or as combi cd (with duplex softener)- uo-d series 600 – 2,000 l/h with ro digital also as combi c or combi cd and available with fu frequency converter for energy savings of more than 30 % as an option. the new uo-d 2000 with vertical pressure vessels for a small footprint- Kr series lower water consumption thanks to high permeate recovery of up to 90 %- nd/P series highest salt rejection rates of more than 99 %- uo-ed Z series our counter pressure unit: most hygienic design preventing microbiological contamination - uo-d as / fu series lowest energy consumption; additional energy saving kits available as an option

definitions

soft water: Water that has been pre-treated with a water softening unit. We are happy to provide a quote for a unit to suit your specific needs.

hardness stabilised drinking water: small amounts of antiscalant are added to the feed water upstream of the reverse osmosis unit in order to prevent salt deposits on the membranes (scaling).

fu: Pump with frequency converter to save energy.these pumps at least comply with the requirements of energy efficiency class ie3, up to 4 kW even ie5.

Herco reverse osmosis units are economical

every unit can be adapted perfectly to your needs due to herco's modular concept of the whole water treatment line and the ability to add options and accessories.

special versions and special permeate capacities can be manufactured at any time. don't hesitate to contact us.

herco water treatment equipment does not only mean maximum reliability for you and your customers, but also a highly competitive price and cost-efficient operation thanks to optimised consumption.
