Vertical Mount System
    7000–BHL–4

 

The BHL Series has been especially designed for small Hotels, Marinas and Waterfront Homes with access to salt or brackish water and where supplying clean water can be logistically complex and expensive.

The high power efficiency, ultimate reliability and low maintenance cost of these desalination systems makes high quality fresh water in many cases more economical than municipal water where available.

The newly engineered marine aluminum frame provides tidy appearance while allowing easy access to the systems components for maintenance.

The modular wall mount systems or the self-contained vertical framed systems
are space saving and almost turnkey so that people without engineering backgrounds can install them.

For freshwater capacities of a multiple of 7.000 GPD / 26,495 Liters, the installation of any number of redundant operative BHL desalination modules can produce unlimited output.


More economical than a single large system,
multiple desalination modules provide back
up, ease transport as well as installation and reduce the electrical start up load by more than 35%.

In times of low water demand, only the modules needed are operated for low maintenance and ultimate cost efficiency.

Upgrades are easy, fast and available in
1.800 and 7,000 GPD steps.

If a seawater well/spear/bore or open seawater intake at a lower water level is used, the installation of a submersible feed pump is recommended. A sand filter (multi media filter) installed before the cartridge pre-filters can
reduce filtration cost.

    "I have used the system for more than eight years for between 10 and 24 hrs per day to supply water for normal household and building needs and finally a 15,000 sq.ft. garden maintenance with lawns, fruit trees and vegetable garden. My average fresh water production is 700 gallons per day, for a total of over 2 million gallons to date. The system has been very reliable. Careful attention to the regular oil change for the high pressure pump and  normal consumable replacement at intervals is all that is required to maintain a high quality of product water." Read full Testimonial
