Modernization of
Existing Systems

Enhance your existing air and water treatment systems with our quick-return modernisation programmes!
Rapid ROI
Great Flexibility

Get the most out of your existing system

We developed our modernization service to offer support beyond just large-scale investments.

Whether it’s about system-level integration of synergistic solutions or modular plug & play upgrades, our extensive portfolio and wide-reaching partner network enable us to breathe new life into any existing system.

Don't replace it
- upgrade it!

New isn’t always the optimal solution. Upgrading existing systems can deliver significant results — often with lower environmental impact and greater cost efficiency.

Dramatic improvement in efficiency

  • Up to 85% lower input energy demand
  • Improved performance
  • Reduced operating costs
  • Optimized capacity without oversizing

Real sustainability

  • Use of natural refrigerants
  • Lower CO2 emissions
  • Water savings and recycling
  • Modernization instead of scrapping

Minimal intervention

Many of our partners chose modernization after realizing it delivers significant results faster and more cost-effectively than building a completely new system.
  • Szorgalmas Gábor
    Gyárigazgató • Toyo Seat Europe
    „Eleinte nagyon szkeptikus voltam a megjósolt magas energiamegtakarítással. Miután telepítettük a rendszert, már módomban állt megvizsgálni a teljesítményt, ami a szokásos elvárások felettinek bizonyult.”

  • Sereghy Szilárd
    Maintenance Manager • Filtrona Filters Kft.
    „Három problémát oldott meg az adiabatikus rendszer: a magas energiaköltségeket, a magas hőmérsékletet és a párásítás hiányát.”

  • Szili Szabolcs
    Gyárigazgató • UNITED CAPS Duna Zrt.
    „Első nap, amikor bekapcsoltuk még tesztüzemben a berendezést, már egyértelműen látszott, hogy azonnal képes a hőterhelés alatt álló fröccsöntő gépeink teljesítményét optimalizálni.”

  • Fehér Gábor
    Vezető mérnök • Filtrona Filters Kft.
    „A rendszert tiszta szívből tudom ajánlani,
    különösen új rendszerek alkalmazásánál egyértelmű
    a költségcsökkenés elérése.”

What makes Oxyma's approach different?

Modernizációs szolgáltatásunkkal legfőbb célunk, hogy a piacon elérhető standardizált cseremegoldások helyett valóban fenntartható, technológiailag fejlett alternatívát kínáljunk a klímatechnikai rendszerek továbbfejlesztéséhez.

A HVAC modernizációs projektek ügyfélre és igényre szabott megoldásokat kívánnak, mi pedig ebben vagyunk a legjobbak.

Engineering precision

We don’t just make recommendations — we forecast. Every system we design is based on weather-driven simulations, energy and thermal calculations, and a thorough on-site audit.

Continuous innovation

We continuously refine our solutions and work with technologies from the world’s leading climate technology companies, ensuring we always deliver the most advanced systems available.

Local manufacturing, fast response times

Thanks to our local manufacturing base and integrated partner network, we’re able to serve our clients with short lead times, flexibility, and reliability.

Client-focused consulting

We don't sell products — rather, we solve problems. Every project is treated as a unique challenge, and we only recommend solutions that truly align with our clients’ needs and goals.

Water as a refrigerant

Water is one of the most powerful and abundant refrigerants on our planet, and it has a high enthalpy of vaporization. In two-stage adiabatic systems, 95% of the cooling performance is derived from this evaporation, meaning that significant temperature reduction can be achieved with relatively small amounts of water.
Adiabatic cooling, humidification

Beyond its cooling capacity, it offers a range of additional benefits

No ozone depletion potential
Zero CO2 equivalent
Not poisonous
Non-explosive & non-flammable
No contribution to global warming or greenhouse effect
Re-enters the natural cycle through evaporation
Natural, F-gas free
Available both globally and locally, and fully recyclable
Cost-effective

What does this mean for your facility?

No HVAC regulatory permit required
No need to hire a certified HVAC technician
Exempt from mandatory leak inspections
Eliminates the use of hazardous HFC and HFO refrigerants
OVERALL, YOU’LL HAVE FEWER HEADACHES AND LOWER COSTS!

Innovation – through both our technologies
and our process
