MODEL 5K LAB, and MODEL 10K Generators
The Models 5K and 10K Generators have a recirculating blower that operates during the decontamination, with an explosion proof motor capable of 100 and 200 CFM respectively. The incoming air to the generator is heated with an inline heater to enhance the ability of the air to absorb formaldehyde gas. This heater is designed not to allow direct contact with the formaldehyde laden air and a spark that may create a hazardous condition. A built-in humidifier increases the relative humidity of this air to a minimum of 60% prior to formaldehyde insertion. Depolymerization of the paraformaldehyde and neutralizer occurs in aluminum canisters mounted on the top of units. These components, along with the controls, are mounted on a cart with casters for easy movement. A control panel containing all the controls and indicators is mounted on top of the cart. A computer-type controller is utilized to control the various functions of the generator. The message center, mounted on the front of the control panel, indicates the progress of the cycles.

Companion Product: Safemod / Safescan Ultra High Efficiency Containment Filter Modules
The SAFEMOD may be changed safely with their normal changing procedure. A SAFEMOD used in conjunction with the Formaldehyde Generator/Neutralizers enables the decontamination of the installed filters prior to the opening of ductwork components, thereby enhancing safety for the maintenance personnel.
Features	SAFEMOD
Modular Filters for Hazardous Applications Handled as Completely Contained Module Available With Particle and Gas Phase Filters Factory Tested to Ensure Integrity Modular Construction Permits Multiple-Size Installations
Typical Installation With Multiple Modules

General Operating Protocol – All Models

The space to be decontaminated is measured and the volume calculated in cubic feet. The space is then sealed. The relative humidity inside the space is measured or sensed, depending upon the model. The CERTEK Generator / Neutralizer generator is then connected to the space with the appropriately sized connections. The humidifier, formaldehyde, and neutralizer canisters are then loaded with the proper amount of material as calculated using the formulas in the operating manual or the amount determined by other evaluations. The generators are then programmed with the operating sequence choices as determined by the operator and then started by pushing the "Start" button. The space is then conditioned to the proper relative humidity. After this is accomplished, the generator starts formaldehyde insertion. The amount of air required to insert the formaldehyde/neutralizer is circulated through the generator when the insert sequences are active. After the formaldehyde insertion cycle, the generator holds for a preselected contact time (infinitely selectable). After the contact time, the generator automatically begins the neutralizer insert cycle, inserting the neutralizing gas into the space. At the conclusion of this cycle, a preset one hour neutralizer contact cycle begins. When this is complete, the space may be reopened. The product of the reaction between the formaldehyde and the neutralizer is a white powder, which has a slight “fishy” odor. For safety, the space should be ventilated and air samples taken prior to occupancy.

Built-in safety features in all of the CERTEK generators permit completely automatic operation without the necessity of a technician’s constant attention.
