Halton Vita VDU – Decontamination unit

The Halton Vita VDU is a unique 3-in-1 mobile hydrogen peroxide (H_​2O​₂)​ decontamination unit that provides necessary air filtration, efficient vapour distribution and process verification. ​ ​It has an integrated catalyser and is designed for demanding H_​2O​₂ bio-decontamination processes up to 750 m³ spaces. It uses up to 60% aqueous H_​2O​₂ solution to generate H_​2O​₂ vapours capable of destroying even the most resistant microorganisms, like bacterial spores, in room temperatures and low concentrations.

The process is carefully monitored and verified with integrated H₂O₂ sensor technology. The aeration process with an integrated catalyser removes residual H_​2O​₂ by decomposing into water and oxygen, leaving the space clean, safe, and ready for immediate use.

The Halton Vita VDU uses predefined decontamination programs for different types of areas. In the first stage of the process, filters draw air on both sides of the unit, and adjustable diffusers distribute vapourised hydrogen peroxide (vH₂O₂) from the top of the unit. It is equipped with an integral sensor and facilitates up to four external sensors, allowing verification of complete H₂O₂ distribution throughout the space. When the level of vH₂O₂ in the air reaches a certain level for a certain period, the air filtration phase takes place, and the filter cleans the drawn air inside the unit. The touch panel allows you to control the device remotely via the tablet.

The software inside the PLC (Programmable Logic Control) unit monitors data from the sensor(s). The sensor provides the following data from the enclosed space: hydrogen peroxide vapour ppm, temperature, humidity as relative saturation, relative humidity, dew point, and vapour pressure. Based on the data, the PLC controls the heating, blowing, and dosing of hydrogen peroxide to the vaporising units.

The Halton Vita VDU is a decontamination unit designed for demanding hydrogen peroxide bio-decontamination processes. It uses up to 60% aqueous hydrogen peroxide (H₂O₂) solution to generate hydrogen peroxide vapour capable of destroying even the most resistant microorganisms, like bacterial spores, at room temperatures and low concentrations. Halton Vita VDU decontamination units should always be used only with a compatible H₂O₂ liquid solution. The unit has a user interface consisting of a touch-screen monitor and a Windows CE device. In addition to this the system can have a remote user interface in a mobile device, laptop or desktop computer utilising either wireless 802.11 network or wired Ethernet.

Material

• Galvannealed steel with antimicrobial epoxy-polyester powder paint finishing for sensitive parts such as touch screens, electrical cabinets, service doors, etc.
• Aluminium with antimicrobial epoxy-polyester powder paint finishing for grills, doors and plates

• It contains two filters: a regular filter and a catalytic filter to absorb H₂O₂.

• An integrated control unit that can be connected remotely

Packaging

• The Halton Vita VDU assemblies are packed to EUR/EPAL with pallet collars or tailor-made containers for assembly transportation.

Maintenance

• Annual maintenance involves a comprehensive evaluation and servicing of equipment to ensure optimal performance and longevity. Key tasks include replacing vaporizers to maintain efficiency, calibrating pumps for precise operation, and upgrading software releases where applicable to enhance functionality and security. Additional checks and services may be conducted as needed.
• During annual maintenance, some components are either replaced or calibrated. This list does not include replacement due to damage or negligence by the user.

Service

• The Halton Vita VDU follows quality standards for the feedback process and complaint handling for any customer complaints or issues. The first point of contact for the end customer is the support organisation of the seller organisation. Halton's principle is to provide support during office hours if the customer does not have a service contract in place.
• The process of handling customer cases, claims, or issues is the same during and after the warranty period. However, the customer cases that are related to products with warranty will get priority over the non-warranty time claims. Also, customers with service contracts will have a priority.

Conformity to standards

The product adheres to the following standards and directives, ensuring compliance with EU regulations:

• Standards:
  • EN 55011:2009+A1:2010
  • EN 61000-6-3:2007+A1:2011+A1:2012
  • EN 61000-6-2:2005+AC:2005
  • EN 301 489-1 V1.9.2

• Directives:
  • Machinery Directive (MD)
  • Restriction of Hazardous Substances (ROHS)
  • Radio Equipment Directive (RED)
  • Waste Electrical and Electronic Equipment (WEEE)

This adherence ensure the product follows the required safety, electromagnetic compatibility, environmental, and operational standards.

The Halton Vita VDU is a large device mounted on wheels that can be moved to any location using handles. However, locking the wheels at the location avoids movement during operation.

Installing a Halton Vita VDU that uses hydrogen peroxide (H₂O₂) requires precise planning due to its chemical reactivity and potential safety hazards.

• Ensure the installation complies with relevant safety standards.
• Evaluate environmental controls that affect hydrogen peroxide effectiveness.

• Check H₂O₂ reservoir for appropriate levels

• Room sealing is vital to prevent vapour leakage during operation.
• Ensure adequate drainage for condensate, if any.
• Ensure the spill kits and neutralizing agents are available and nearby.
• Ensure the presence of H₂O₂ personal protective equipment.
• Use only compatible H₂O₂ grade (PT02, PT04).
• Install additional sensors for monitoring H₂O₂ concentration.
• Connect the device to the power supply, typically 16 amp.

Place the device at the desired location to ensure proper coverage. Check that it is accessible for maintenance and operation needs. Ensure that the control panel attached to the device is working as intended and all controls are working, e.g., target concentration, time required for ramp-down, etc.

Ensure that the unit operates as intended, meets safety standards, and effectively achieves the desired level of decontamination.

• Make sure to complete all installation steps.
• Ensure compliance with defined regulatory and quality standards.
• Check that all components are installed correctly without any damage.
• Confirm that the device is connected and operational without any errors or malfunctions.
• Place chemical indicator (tape that changes colours over 300 ppm of H₂O₂) in hard-to-reach areas to confirm H₂O₂ reach visually.
• Monitor H₂O₂ levels after the cycle to ensure re-entry.
• Ensure desired decontamination levels are reached.

Annual maintenance of Halton Vita VDU involves a comprehensive evaluation and servicing of equipment to ensure optimal performance and longevity. Key tasks include replacing vaporisers to maintain efficiency, calibrating pumps for precise operation, and upgrading software releases where applicable to enhance functionality and security. Additional checks and services may be conducted as needed, addressing any specific issues or requirements unique to the equipment to ensure seamless and reliable performance throughout the year.

During annual maintenance, some components are either replaced or calibrated. This list does not include replacement due to damage or negligence by the user.
