Current Issues

Living animals transport, is probably the main way of transmission of diseases among swine farms. At OPP Group we like to think that the bio-security level of a farm is as good as the cleaning and disinfection of the vehicles that visit the farm.

In this context, it has been proven that the PRRS virus spreads primarily through pig transport vehicles, much more than through other ways of transmission (air, contact with personnel, etc).

Chemical truck disinfection systems currently used, face several problems:

  • Dilution of disinfectants and their inactivation in the presence of organic substances
  • The time required for the elimination of bacteria
  • Major accumulation of disinfectants on the truck after finishing the process, which freeze at cold seasons of the year
  • Grave environmental damage caused by the use of liquid disinfectants


Our Answer to the Problem: DrySist

OPP Group, has developed an innovative system of thermal decontamination, the DrySist system.

Our goal with for DrySist, is to offer the market a fast, reliable and safe disinfection system, which minimizes environmental damage and reduces the financial cost of each disinfection.

Besides, DrySist confirms and issues n electronic certificate of the success of the disinfection process, so that each process is registered and communicated in real-time to people or institutions that the user considers appropriate.

The disinfection process of DrySist is divided in three phases:

  1. Thermo-decontamination of the animal transport box. (monitored through 6 to 9 temperature sensors)
  2. Nebulization of a disinfectant compound in low quantities, but with high penetration in the bearing area and the chassis of the truck
  3. Manual disinfection of the cabin, following the North American PED protocol
