System catering & counter service – Exhaust air purification for the frying area

Space-saving air purification above the counter – odorless, approvable, efficient

In system catering, every square meter counts. French fry stations and snack modules are often integrated directly into the counter – without space for central ventilation, roof ducts, or technical rooms. At the same time, strict requirements apply here too in terms of odor, hygiene, and fire protection.

With the oxytec countertop attachment for frying modules, you get a compact and powerful solution for exhaust air purification – with UV ozone or plasma, without an exhaust air duct to the outside, low maintenance, and ready for immediate use.

FAQ – Frequently Asked Questions

Is it even possible to have an odorless frying station at the counter without an exhaust vent to the outside?

Yes, this is possible with Oxytec systems.
Our countertop attachments with integrated UV ozone or plasma technology clean the air so effectively that it can be blown out directly into the room without any odor—even without an exhaust duct or roof vent.

How does odor removal work for fried foods?
  • Plasma oxidizes odor molecules, grease particles, and VOCs directly in the hood.
  • UV ozone technology breaks down organic compounds and neutralizes odors.
  • Both processes are particularly effective for intense odors such as those from French fries, currywurst, or frying oil.

What permits do I need to operate in a food court or gas station bistro?

Our systems meet the requirements of:

  • VDI 2052 (kitchen ventilation)
  • VDI 3894 (odor assessment)
  • TA Luft (Technical Instructions on Clean Air)

This means they are eligible for approval even without an exhaust air duct – ideal for kiosks, gas stations, and shopping centers.

How loud are the devices when in operation?

Our systems are designed to be particularly quiet:

  • No large fan or compressor required
  • < 50 dB(A) – comparable to a quiet refrigerator
  • Ideal for use directly in customer areas or in self-service restaurants

How much maintenance is required?

Very low:

  • UV lamps: Replacement after approx. 8,000–10,000 operating hours
  • Plasma elements: mostly maintenance-free, visual inspection is sufficient
  • Prefilters (e.g., grease separators): rinse regularly or dishwasher-safe
  • No activated carbon → no consumable costs

Can I also integrate the systems into existing counter modules?

Yes – we offer:

  • Retrofit solutions for existing hoods or modules
  • Compact designs for installation under, behind, or above the fryer
  • Individual adaptation to your system catering – whether snack bar, franchise, or self-service restaurant

How quickly can the system be put into operation?
  • Plug & Play – set up, connect, start
  • No external air duct required
  • Can also be used on the go – e.g., at events or for temporary branch solutions

Is there support available for planning and communicating with authorities?

Yes – we offer:

  • Planning support, CAD integration, and customization
  • Technical documentation for submission to health or building authorities
  • Service partners throughout the German-speaking region
  • Short delivery times and quick commissioning

How high is the energy consumption?
  • UV and plasma modules are very energy-efficient, usually < 100 W
  • No heating process, no air extraction = significantly more efficient than central ventilation
  • Low operating costs, no CO₂-based losses due to warm exhaust air
