OptiShield

Corrosion Solutions by Opti Temp, Inc.

The OptiShield family of corrosion inhibitors has been specifically formulated to control corrosion in systems circulating fluids to industrial machines such as lasers, welders, machine tools and other process equipment.  OptiShield is exceptionally effective where copper, tin, ferrous metals, lead, brass and other yellow metals are included in a closed circuit fluid heating/cooling system.  OptiShield prevents galvanic action from occurring between any of these dissimilar metals, as well as prevents oxidation of the ferrous metals in the system.

Please contact Opti Temp if Aluminum is present in the system.
Caution - DO NOT USE
OptiShield II Plus  if aluminum is in your fluid circuit!


There are four (4) OptiShield products available:

  • OptiShield is for applications that do not require low conductivity.
  • OptiShield II is for applications that require low conductivity.
  • OptiShield Plus is for applications that do not require low conductivity, but has an added ingredient that will provide an unfriendly environment for algae.
  • OptiShield II Plus is for applications that require low conductivity, and contains an added
    ingredient that will provide an unfriendly environment for algae.
    Caution - DO NOT USE OptiShield II Plus if aluminum is in your fluid circuit!

The OptiShield family of products are available in pint, gallon, 5 gallon and larger sizes up to 55 gallons.



OPTISHIELD

OptiShield® Original Formula

OptiShield Original formula has been formulated to control corrosion in systems circulating fluid to industrial machines such as lasers, welders, machine tools and other process equipment. It provides broad corrosion protection for systems with a range of materials including copper, brass, aluminum, tin, ferrous metals, lead, and other yellow metals.

OptiShield® II

OptiShield II Low Conductivity Formula OptiShield® II corrosion inhibitor has been specially formulated to provide corrosion protection in systems such as laser, welding, induction, and other equipment where "electrical conductivity" of the fluid is of concern. The lower conductivity of OptiShield II allows its use in some systems where protection is not otherwise available due to system/fluid conductivity specifications.

Filtration Products for industrial chillers

The use of filtration is highly recommended for use when OPTISHIELD® or other corrosion inhibitors present in the system. When corrosion inhibitors such as OPTISHIELD® are added to a system, they dislodge the corrosion particles into the fluid stream where the filter removes this residue before it can damage the pump, and/or other components in the system.

The filters are normally installed in the return line of the OPTI TEMP® heat transfer units or chillers to filter the fluid returning to the system. This will keep the residue from settling out in the reservoir. The standard filters offered will filter particles down to 30 microns in size.

For other filter sizes please call Opti Temp at 231-946-2931.

Corrosion Control for Liquid-Based Cooling Systems

OptiShield is a family of corrosion control products offered by Opti Temp for water-based cooling systems.  OptiShield is pH basic and provides an unfriendly environment for algae. When used as directed, OptiShield "original" formula is a safe, effective corrosion control solution for most general industry applications.

OptiShield corrosion inhibitor is a water-based liquid additive specially formulated to protect closed-circuit process heating and cooling systems from galvanic corrosion, which results from the presence of dissimilar metals within the recirculating system. The OptiShield corrosion control products have excellent heat transfer characteristics and are normally classified as “non-hazardous."

Closed-circuit heating and cooling systems often contain various dissimilar materials such as copper, brass, aluminum, tin, ferrous metals, lead, brass, and other yellow metals. When dissimilar metals are present within an untreated system, galvanic corrosion normally results, due to differences in the electro-chemical potential of the materials. Left untreated, galvanic corrosion often leads to pump/seal failures, reduction in heat transfer efficiency, reduced flow, lost revenue, associated downtime, and expensive cooling system repairs. OptiShield inhibitors are very effective in controlling galvanic corrosion in recirculating systems.

    Pure water (H20) is colorless, tasteless, and odorless. It is composed of hydrogen and oxygen. Because water becomes contaminated by the substances with which it comes into contact, it is not available for use in its pure state. To some degree, water can dissolve every naturally occurring substance on the earth. Because of this property, water has been termed a "universal solvent." Although beneficial to mankind, the solvency power of water can pose a major threat to industrial chillers, laboratory chillers, process chillers and other cooling systems.
