Automatic Formaldehyde and Ammonia Evaporator
Functioning of Automatic Formaldehyde and Ammonia Evaporator
Essence of the method is lengthy (not less than 6 hrs) exposure of the cabinet leak-tightly isolated from external environment to the formaldehyde vapors (НСНО) with high humidity level in order to kill microorganisms and spores. After that formaldehyde vapors are neutralized with ammonia vapors (NH3).
Evaporator is placed inside the cabinet’s work chamber; appropriate amounts of reagents are placed into evaporator’s storage tanks; appropriate time limits of exposure are entered to evaporator’s control system; after that the cabinet is sealed with special tools or with air-tight bag from the external environment. Evaporator is activated inside the cabinet and the process continues automatically.
To achieve high humidity with formaldehyde vapors, formalin solution (37%) is evaporated with an equal amount of water.
To generate ammonia vapors, aqueous ammonia solution (25%) is evaporated.
Main features of Automatic Formaldehyde and Ammonia Evaporator
- evaporator’ casing and reagents’ tanks are made of stainless steel;
- reagents’ tanks are provided with screw on caps;
- control unit is leak-tight isolated from evaporation unit and from environment;
- control unit is supplied with an LC Display, keyboard and additional led indicators;
- evaporator is supplied with folding handle for transportation convenience;
- power cable is incorporated in the evaporator’s case.

Function
The treatment is carried out in accordance with EN 12469:2000. A 37% formaldehyde (CH2O) solution with equal volume of water is evaporated inside the cabinet (tightly isolated from the external environment) for at least 6 hours in order to ensure the destruction of microorganisms and spores. To saturate the formaldehyde vapor, a 25% ammonia (NH3) solution is evaporated afterwards.
To carry out the procedure, the evaporator is placed into the work chamber of the cabinet, evaporator tanks are filled with needed chemicals, the control system is set to the required periods of operation; then, the cabinet is isolated from an external environment using a leak-tight bag. The formaldehyde and ammonia evaporation processes are activated inside the bag. The whole process is automatic.
To get the formaldehyde vapor and ensure high humidity, the 37% formaldehyde solution is evaporated with an equal volume of water.
To get the ammonia vapor, a 25% ammonia solution is evaporated.
