In intensive poultry production systems, microbial contamination
and viral respiratory infections are among the key factors behind
performance loss and high mortality.
Leveraging its expertise in chemistry and gaseous formulation
technology, Nojan Pharmed Pasargad has developed a new generation
of gas-phase biosecurity products that release active compounds in
a controlled manner ensuring comprehensive disinfection, microbial
load reduction, and improved respiratory health across the farm
environment.
ViroKiller PFA
Paraformaldehyde Based Gaseous Disinfectant
Designed for pre-chick placement disinfection
Mode of Action:
ViroKiller PFA is a paraformaldehyde-based formulation that, upon
activation, releases formaldehyde gas, penetrating all areas of
the poultry house — even inaccessible corners.
With its powerful biocidal activity, it eliminates a wide spectrum
of viruses, bacteria, fungi, and spores.
Key Features:
- Complete sterilization of poultry houses before flock placement
- Eliminates unpleasant odors, molds, mites, and residual contaminants
- No need for spraying, misting, or heating systems
- Rapid, uniform gas dispersion across all surfaces
Dosage:
1 L per 1000 L of drinking water
Duration:
- 400 g canister = 1200–800 m³ space
- 1000 g canister = 2500–2000 m³ space
Result:
Fully sterilized facility ready for flock entry minimizing cross-contamination risk
ViroKiller OPP
Ortho-Phenylphenol Based Gaseous Disinfectant
For in-production use and viral respiratory control
Mode of Action:
ViroKiller OPP contains activated gaseous ortho phenylphenol,
allowing safe use inside occupied poultry houses.
It reduces airborne and surface microbial loads, helping maintain
flock respiratory health without the need for evacuation or
mechanical spraying
Key Features:
- Reduces microbial load in air and surfaces during production
- Lowers mortality caused by respiratory viruses (notably ND & IB)
- Simple to use — no spray, heat, or evacuation required
- Suitable for both preventive and active infection phases
Dosage:
- 400 g canister = 1200–800 m³ space
- 1000 g canister = 2500–2000 m³ space
Result:
Improved respiratory comfort, stronger vaccine response, and reduced mortality.
Recommendation:
Based on multiple field observations of ViroKiller OPP use under disease challenge, as well as practical on farm documentation, it is recommended, subject to the supervising farm veterinarian’s judgment, that in the following situations ViroKiller OPP may be used at half the standard dose:
- during outbreaks of viral diseases such as avian influenza, Newcastle disease, Gumboro (IBD) and even Angara, or
- to reduce the microbial load in the poultry house and help maintain flock vaccination titers
After activating the product, keep all air outlets (e.g. fans) closed for 20–15 minutes, and then resume normal ventilation
Deltament
Next-Generation Menthol Based Gaseous Bronchodilator
Designed for respiratory relief during infection periods
Mode of Action:
Deltament is an advanced gaseous bronchodilator formulated with
natural crystalline menthol, which vaporizes evenly throughout the
poultry house.
The menthol vapor provides cooling, anti-inflammatory, and
decongestant effects, supporting normal respiration and reducing
wheezing and labored breathing
Key Features:
- Natural airway dilator (Menthol Vapor Action)
- Helps clear respiratory mucus and enhances oxygenation
- Reduces respiratory distress during IB and influenza outbreaks
- Fully biocompatible — no chemical residues
Dosage:
ul class="mb-5">Result:
Rapid relief of respiratory stress, restored appetite, and calmer flocks during infection.
Advantages of the Nojan Gaseous Biosecurity Package:
- Complete sterilization — no water, heat, or spraying required
- Effective microbial and viral reduction in both empty and occupied houses
- Modern alternative to traditional disinfectants and fogging systems
- Time-saving pre-placement sanitation and reduced production losses
