purventus GmbH

Purventus has been active in the area of air purification since 1999 and develops, constructs and offers environmentally friendly air and exhaust air decontamination systems.

The air on the earth is cleaned by the sun. Odours, bacteria and viruses are minimised by the UV light. Purventus UV filters do the same thing and reduce fat deposits in exhaust air systems in the simplest way with the least possible energy use and reduce odour carrying substances and micro-organisms in the air by up to 99.9%.

It produces UV radiation under controlled conditions in defined wavelengths. These break down fat molecules and create ozone (O3) in connection with atmospheric oxygen (O2). Ozone is extremely reactive and oxidizes substances like fats, nicotine smoke or odour carrying benzol.

The result is 100% biodegradable waste materials, water, oxygen and carbon dioxide. Due to its high level of reactivity, ozone also kills off micro-organisms and therefore has a disinfecting effect. The cost savings for operators are enormous.

But even more important is the fact that the operation is safe and there are no problems with authorities, the neighbourhood or guests due to odour problems.

The definitive USP is the ability to be able to completely clean the UV module in the dishwasher.

Purventus is represented by distributors/sales partners across the globe. The UV filter is mainly manufactured in made-to-order production and is independently marketed.

Purventus is both a manufacturer, distributor and a project developer.

Benefits at a glance:

• Clean air without chemicals

• Exhaust air decontamination, disinfection and sterilization

• Neutralises odours

• Reduction of fire loads

• Reduces operating costs (for filters, air canal cleaning, electricity)

• Effective, environmentally friendly and easy to manage

• Can be integrated into almost any ventilation system

• McDonald´s, Burger King and KFC under the Franconian Foodservice brand (licenced production)

• Commercial kitchens/canteens

• Transport restaurants (airports, train stations, etc.)

• Breweries and hostelries

Have you seen something like this before?

But that's how it looks in some places

No?

4

But this is also reality

Fat and grime in the exhaust duct

In some kitchens fat pours out of every pipe

all of them “excellentfire accelerants“

noconventional filtercan prevent that

What can happen when trying to save money in fire protection

400 deaths at a shopping centre in Paraguay 2003

and what a small fire from a deep fat fryer can cause:

these little critters feel right at home in every exhaust duct

6

what else can be found in the duct?

when there happens to be no fire ...

These boys are also not to be scoffed atthey live on fat and dirt and also like to take it easy ...

7

You want the best for your customers?

It's grimy and it stinks

It's a real fire hazard

But how ... can we solve these problems?

• with fire extinguishers?

• with no more hamburgers on the grill?

• Filters? What kind then?

• Hold your nose?

• clean the duct every 14 days?

8

Of course these problems can be solved

but with what amount of effort ...

Duct cleaning with lots of chemicals and pressure?

• Downtime • High costs • Waste water pollution • not everything can be

made clean • it still smells • there's fat in the duct

again

9

Even these “filters” don't remove the fat

Aerosol separator (Flame protection filter)

Electrostatic filter

Plasma generating filter

Ozone generators

Catalysts

Fat particles < 5 µm are not separated

susceptible to damage, high-voltage, safety risk

absolutely no effect against fat / Oil-aerosols; susceptible to dirt

high ozone concentration (costs); safety risk

no fat reduction, expensive to procure

10

but only: ✓ H2O, CO2, fat pocket, O3

(Ozone)

✓ 100% no longer a fire hazard ✓ up to 90% less odour ✓ up to 100% no germs or

other “critters” ✓ also ideally suited for air-

conditioning units

separates fat molecules, like the sun

That's why we use UV light

then fat is no longer fat and oil no longer oil

That means the ducts stay clean!

Maximum effectiveness!

No other system combines all these benefits

11

• UV lamp cleaning expensive • Safety risk UV rays, as not an enclosed

construction • high level of maintenance and cleaning

expenditure

Here’s how we started

1999

UV lamp mounted directly to the hood

but today we know:

this method has decisive disadvantages

12

Only “closed” UV filters are safe filters

2003

up to today in large unit numbers in fast food chains

But:

The lamps have to be cleanedmanually

if forgotten: Problem !!

Closed construction - no longer a safety risk for employees!

13

Problem solved - now the filters are perfect

since 2012

Further development: ✓ Cleaning in the dishwasher

= Enormous relief for employees = Time and cost savings

✓ Closed, robust construction, ✓ Easy to operate ✓ For grill or deep fat fryer hoods

UV attachment module Type: Manox

14

One further highlight: the “Innox” universal filter

✓ Fits every duct, ✓ Fits on or to every exhaust hood ✓ “generates” any exhaust volume

through the connection of any number of additional modules in a row or parallel

Very easy to operate: ✓ Plug & Play ✓ The entire module can be

placed in the dishwasher ✓ Maintenance by way of

simple exchange without downtime

UV-C Universal module Type Innox

for restaurants, hotels / university cafeterias and commercial kitchens

Exhaust ducts no longer have to drip with fat

... over a deep fat fryer and a grill

This is how they look when fitted with purventus UV filters

After 4 months: absolutely no deposits

And after 12 months: The ducts are absolutely dry

17

Here, directly in the duct connections of a grill hood

depending on the performance requirements, can also be mounted next to each other as a dual setup

Possible applications of the “Manox”

Installation directly above a grill or deep fat fryer hood

thereafter: fat-free duct

A MUST for the following equipment - for example:

•Active carbon filter •Sensors (pressure, humidity, etc.) •Heat exchanger •Exhaust air fan

Example installation with lining for 1,500 cbm/h clean exhaust air Your benefit:

18

•Flange dimensions 500 x 300 mm

• can be installed in all duct sizes

•Control module can be installed anywhere

• the plug-in module including UV tubes as part of Plug&Play for cleaning in the dishwasher

Innox - Universal module: fits everywhere

Your benefit: 1,500 cbm/h clean exhaust air

22

Any exhaust air volume possible

General rule: 1,500 cbm/h = 1 UV module

The number of modules can be reduced when taking the size of the kitchen and the type of production into consideration

Example: Equipment for a university cafeteria / company canteen with approximately 10,000 cbm / exhaust air volume = investment of approx. EUR 27,000

For example: Investment and operating costs for a city centre restaurant, in a typical Business and apartment building with 5 storeys, pedestrian zone, inner courtyard with apartment balconies and roof terraces, open daily for 15 hrs, 10,000 cbm / h exhaust air:

EUR 25,954

Not allowed for: • Risk of non-approval by authorities • Fire risk, downtime risk • Hassle from the neighbours due to smell

“Great service, the UV filters from purventus have done a great job for us for years, no fat in the exhaust duct, no fire load”

“Due to odour problems, we have converted our exhaust system to air circulation with purventus. It works perfectly”

This is what satisfied customers have to say

Low ceilings, a large volume of fat and fire protection regulations present us with enormous challenges. With the purventus systems we fulfil all requirements”

“No way of connecting to the fat exhaust air system in the Euro-Passage. With the purventus air circulation system, it works without any issue”

“We used to have another UV system in place, which didn't work. Now, there is zero fat in the exhaust air system”
