Herco Light Commercial RO System


Our Herco Light Commercial RO System is a compact, pre-assembled and cost-effective solution for RO water production. The system offers a permeate flow rate of up to 130 litres per hour, a recovery rate of 50% and an average minimum rejection rate of 95% thanks to its integrated pump. Impressive stats for a unit of its size, making it great for space-sensitive installations (like under a sink or in a small plant room).

Why Choose Our Herco Light Commercial RO System?

  • Supplied with carbon pre-filter and 4021 RO Membrane
  • High permeate production for a system of its size
  • Pre-assembled on a stainless-steel mounting plate
  • Integrated control panel with conductivity meter

The thoughtful system design offers some useful additional features including a pressure switch, a solenoid valve to control automatic flush cycles and the RO 524 control system which displays permeate conductivity, forced stop and full tank. Able to be used for on-demand RO water production or to feed a storage tank thanks to low voltage inputs for up to 2 float switches, this small but mighty system will fill an IBC in under 8 hours.

Suitable for a feed water TDS of up to 1000ppm and a water temperature of up to 35°C. As with all RO systems the permeate recovery and rejection figures depend on several factors such as feed water quality, temperature and the type of pre-treatment used. If your water hardness is over 100ppm it would be recommended to install a water softener prior to the system to prolong the life of the RO membrane.

How Often Do I Need To Replace The Filters In The Herco Light Commercial RO System?
The carbon pre-filter should be changed after 100,000 litres or every 6 months, whichever comes first. The RO membrane should be replaced when you notice a drop in permeate production or water quality. With soft water, membranes can last up to 5 years however with extremely hard water (and no pre-treatment) membrane lifespan can be reduced to 12 months or less.

Lovely company to deal with and prompt delivery. I'm in the scottish highlands and they recognised that post is better than courier for rural deliveries.

I bought the wound sediment filters. I found the filters arrived very quickly. It was later followed by a courtesy call to make sure the product was received and correct.
