ViraTek’s original Misting Tunnel was the model CS2020. It was fabricated for ViraTek by Viking Medical until 2005. At that time, ViraTek made significant design and fabrication changes to the Misting Tunnel and moved the fabrication to a ISO 9001-2000 compliant, stainless steel fabricator who uses cutting edge technology including water jet cutting and wrapped instead of welded construction. Initially, these changes resulted in the model LE2020 Misting Tunnel and the larger model LE2828 Misting Tunnel that eventually evolved into the LE2020”C” and LE2828”C” current models.
In 2005, 2007 and 2009 ViraTek made significant design & fabrication improvements:
In 2009, ViraTek took the suggestions of its current customers and incorporated a clean out tray that runs the entire length and width of the internal conveyor to catch debris and ensure easier cleaning. These models became the LE2020”C” and LE2828”C” Misting Tunnels. ViraTek has continued to make upgrades.
The Misting Tunnel connects to a standard 110 Volt ground fault outlet with 15Amp service. The machine draws less than 5 Amps of power.
The Misting Tunnel is self-contained and therefore does not require any ductwork to be installed. The heat generated by the machine is nominal and basically undetectable.
The sanitizing fluid recirculates and drains back into the reservoir which can then be drained as needed. No floor drain is required, although some customers may find it convenient to have one near to the machine.
TheLE2020C Misting Tunnel is 33” wide, 60” long, and 59 1/2" high and requires at least a 34 ½” doorway opening (a standard 36” door). The LE2828C Misting Tunnel is 38" wide, 60" long and 67 1/2" high and requires at least a 40" wide doorway opening.
When not used in a barrier setting, the Misting Tunnel alone requires no installation. It is simply rolled into the desired location and the casters are locked and the Off-Load Conveyor is hooked to the off-load end. If the Misting Tunnel is being used in a barrier (dirty to clean room) setting, the Pass-Through Door provides a fixed location. (see below)
Yes. When used in a barrier facility (dirty to clean room), the Misting Tunnel can be mounted permanently to a wall using the optional Pass-Through Door. The Pass-Through Door is mounted in the wall between the dirty and clean rooms. The Misting Tunnel is then rolled into place on the dirty side and sealed against the Pass Through frame. The off-load conveyor is hooked to the brackets on the door side of the Pass-through in the clean room. The wheels are left on the Misting Tunnel to allow ease of maintenance in case any problem should arise.
There are two Emergency Stop buttons; one located on the load end and one on the off-load end. In addition, there is a torque limiter mounted to the drive motor, a load end Chain Guard and an Electric Eye Beam Activator. Safety notices are located on each end of the conveyor.
There is a permanent in-line stainless steel mesh filter that needs to be regularly rinsed in hot water to remove any debris, usually once per week. There are individual stainless steel mesh filters mounted inside each misting nozzle that should be regularly cleaned with a cotton swab, usually once a month. The nozzles are easily removed with a ½ inch socket. These cleaning recommendations are based on average use and will vary by user depending on the amount of fluid going through the machine and should be increased or decreased accordingly.
The conveyor belt speed can be increased; the electric eye delay can be adjusted; the flow rate of chemical can be adjustment; the conveyor belt torque can be increased or decreased
The off-load conveyor has a range from 2 feet to 8 feet in length. The conveyor can be turned from side to side to approximately a 30-degree angle and with additional optional conveyor attachments can form a 90-degree turn if desired.
The off-load conveyor has three sets of legs, each with a swivel locking caster that can be adjusted in height independent of the Misting Tunnel.
The LE2020C LE2828C Misting Tunnels have a 3-gallon reservoir that supply the misting nozzles.
Any chemical that is pH neutral and produces little or no residues can be used in the Misting Tunnel. Contact ViraTek to discuss chemical options.
