Features & benefits

The Isan system substantially reduces the incidence of fungal growth, spoilage organisms and pathogens in water and on food:

Effective chlorine replacement

Comprehensively replaces disinfection by existing chlorine wash systems, eliminating all of chlorine’s negative aspects and handling problems including growing environmental issues at the same time as providing a powerful biocide.

Higher kill rates on bacteria and fungi

Extensive testing and industry use has proven that the Isan system consistently achieves high bacteria, fungal and pathogen kill rates in both water solutions and on a wide range of fruit and vegetables.

No pH adjustment

Chlorine only operates effectively within tightly controlled pH levels. As chlorine is added to water, pH moves outside these limits, making the chlorine less effective as a disinfection treatment.

By contrast, iodine operates in a very wide pH range. It has little or no adverse effect on pH, eliminating all of the pH monitoring problems encountered with chlorine.

Environmentally friendly

The Isan system is one of the world’s most environmentally responsible and friendly disinfection systems. Virtually no biocide by-products escape into the environment. The complete process captures all by-products and converts the captured by-products back into the original biocide, providing an environmentally clean closed loop process.

Almost no corrosion

The Isan system is far less corrosive than any other system:
- iodine itself is seven times less corrosive than chlorine;
- the concentration of iodine used is usually five to ten times less than chlorine dosage.

Iodine – the ideal biocide

For over 100 years, iodine as a disinfectant has been recognised as one of the most effective medical antiseptics available. Even NASA recognises iodine’s unique qualities, using it as the only water disinfection process on all manned space flights. It is also an essential ingredient in our daily diet.

No chemical mixing

Chlorine and fungicide use involves diluting and mixing highly toxic chemicals.
By comparison, the Isan system uses a patented form of iodine, which is supplied in a sealed canister. Handling or mixing of chemicals is eliminated – totally.

Automatic adjustment to organic load

The Isan system constantly monitors the active iodine disinfectant available, and quickly self adjusts dosage levels to meet any increase in the organic load. This fully automated process happens in ‘real time’ and is a unique feature of the Isan system.

Fully automated

Every Isan System is equipped with a fully automated computerised control system. This system electronically monitors the biocide level and automatically doses the water to maintain preset levels. Electronic monitoring of the remaining iodine helps to ensure timely replacement of canisters. Every Isan System has in-built modem communication facilitating system control and monitoring as well as on-line diagnostic support.

Complete data logging

Disinfection levels in the wash water can be recorded in any preset time cycle and stored permanently. These logs provide your customers and HACCP auditors with certified proof on constant and effective disinfection levels. No more hand- written reports.

Q/A Audit certificates

Customised audit certificates can be generated automatically for all batches of produce disinfected. This certificate can be printed and/or emailed direct to your customer.

Safe and user-friendly

The Isan system is the safest and most user-friendly disinfection system available. Its controls warn the operator of any breach of preset levels and also, in certain circumstances, can shut down the system. These warnings can be audible, visual and/or sent electronically to a telephone or a computer.

Eliminates chlorine from the food chain

Being iodine based, the Isan system eliminates the significant risk of food operators introducing chlorine-based carcinogenic by-products into the environment or the food chain.
