Using this proven technology, Spectra now is applying it directly to the intake raw water to permanently prevent scaling and biological-fouling, the principle cause of failure in your water circulating equipment. Fouling has been labeled as unavoidable by many sources. The origin of fouling varies and can be mineral, biological or a combination of both.

Bio-film is the slick coating or slime found on wetted surfaces produced by many types of microbes. A thin layer of bio-film usually coats the interior of piping, strainers, heat exchangers and other equipment when exposed to water. This bio-film provides both habitat and food supply for a range of bacteria and scale forming compounds. The Z-Guard™ will eliminate conditions that foster biofouling, scaling and barnacle growth.

How it works
As water enters the reaction chamber it is exposed to a powerful electrostatic field charging all water molecules in a positive orientation. This positive charge prevents particulates from bonding to one another, preventing the formation of sludge, scale and biological fouling. The wetted charged surfaces form a strong boundary layer preventing particles from attaching. Bacteria are rendered inactive and unable to absorb nutrition to replicate into colon- ies. With the Z-Guard™ you can eliminate the fouling and scaling of watermaker membranes, heat ex-changers, chillers and condensers now and forever.

Convenient
No more hoses, buckets or dangerous chemicals. The inconvenience of having to apply chemicals to watermaker membranes, heat exchangers, chillers and condensers is gone forever. Spectra’s new environmentally sound technology will maintain your equipment without the cost and hassles related to conventional maintenance.

Do Not Use Chemicals
Repeated use of chemicals will substantially shorten the usable life of watermakers, heat exchangers, condensers and chillers. The Z-Guard™ will not allow bio-growth or scaling to attack your system, maintaining the overall performance of your units while dramatically increasing the life of the equipment.

Sized to Fit Your Needs
Z-Guard™ Systems are available in 7 gallons per minute and 16 gallons per minute configurations. Please contact your local Spectra distributor or Spectra’s San Rafael factory for higher flow rates or custom applications.
