Zukunftssicher nachrsüten: HLK-Lösungen von morgen schon heute
Bei Nachrüstungen geht es nicht nur darum, alte Geräte zu ersetzen, sondern auch darum, Ihre HLK-Systeme zukunftssicher zu machen und ihre maximale Leistung wiederherzustellen.
Bei FläktGroup befassen wir uns mit zwei zentralen Herausforderungen, die oft unbemerkt bleiben, bis sie sich auf Ihren Betrieb auswirken.
Challenge 1
Outdated Systems No Longer Fit for Purpose
Your equipment may have been state-of-the-art when installed, but technology and standards evolve. Today’s systems offer significant improvements in:
- Energy and power efficiency
- Environmental noise reduction
- Adaptability to changing building usage (e.g. expanded production or office space)
- Compliance with new legal and regulatory requirements
- Integration with modern building network controls
- Upgrading ensures your system meets current demands and future expectations.
Challenge 2
Maintenance Gaps That Impact Performance
Even high-quality systems can suffer if not properly maintained.
Over time, build-ups, wear, or unnoticed damage can reduce efficiency and degrade output — costing you energy and performance.
To keep your business running smoothly during retrofit, we can provide interim or backup equipment tailored to your needs.
Availability of Parts & Improved Serviceability - Ageing systems rely on components that may no longer be produced. Renovation replaces obsolete parts with modern, serviceable components that ensure long‑term reliability.
Reduced Downtime and Improved Business Continuity - Upgraded systems experience fewer failures, reducing disruptions and supporting higher productivity—critical in environments such as Pharma production or educational buildings.
Efficiency Loss in Ageing Systems - Without proactive maintenance or modernisation, HVAC performance can decline rapidly.
- Efficiency typically drops 15–30% within just 2–5 years. (ASHRAE; CIBSE; DOE).
- Energy consumption may increase by 20–40% over the equipment’s lifetime due to fouling, leaks, worn components, and outdated controls. (ASHRAE; CIBSE; DOE).
- Renovation restores performance, reduces energy waste, and extends equipment life.
Improved Energy Balance and Lower CO₂ Footprint - Modernised units achieve significantly better energy efficiency, reducing both operating costs and environmental impact. This supports sustainability commitments and corporate carbon‑reduction strategies.
Better Protection Against Rising Energy Prices - Higher‑efficiency systems help stabilise operating costs and reduce vulnerability to future energy‑market fluctuations.
Environmental Friendliness & Regulatory Compliance - Renovation helps buildings meet current directives such as:
- EPBD (Energy Performance of Buildings Directive)
- BACS (Building Automation and Control Systems requirements)
- Mandatory energy inspection of air handling units. Upgrades improve compliance while supporting greener building operation.
Respecting Protected or Historic Buildings - Renovation solutions can be designed to fit within existing structures, making them ideal when major building alterations are not allowed.
Understanding Lifetime Costs and Efficiency Loss in AHU Systems
In this example you can see on the left side we highlight the Total Cost of Ownership (TCO) for an Air Handling Unit (AHU).
While the initial investment represents only a small portion of the overall cost, energy consumption and ongoing maintenance make up the majority of lifetime expenses. This is why retrofitting existing units can deliver significant long‑term savings.
On the right side we illustrate the efficiency loss associated with belt‑driven fans. Due to mechanical components and transmission losses, up to 40% of the fan’s efficiency can be lost, making modern direct‑drive solutions far more attractive.
A Complete HVAC Retrofit Solution – Smarter, Greener, Stronger
Upgrade your HVAC system with a single, integrated retrofit package that combines advanced AHU controls, high-efficiency heat exchangers, and modular fan wall technology — designed to deliver maximum performance with minimal disruption.
Whether you're aiming to reduce energy consumption, improve indoor air quality, or extend the life of your existing air handling units, our retrofit solution offers:
- Smart Controls: Modernise your AHU with intelligent control systems that optimise airflow, temperature, and energy use — all with remote monitoring and diagnostics.
- Efficient Heat Recovery: Our high-performance heat exchangers help recover energy and reduce operational costs, supporting your sustainability goals.
- Fan Wall Technology: Replace outdated fans with a modular fan wall system for improved redundancy, quieter operation, and scalable airflow.
This all-in-one package is ideal for facilities looking to future-proof their HVAC infrastructure without the cost and complexity of full system replacement.
ROI from Retrofit Solutions: Proven Results Across Pharma and School Buildings
This infographic presents the return on investment (ROI) achieved in three different case studies using retrofit solutions.
Each example demonstrates how upgrading existing systems with our solution delivers measurable financial gains, improved performance, and long‑term value.
Importantly, the ROI shown reflects the specific investment volume of each individual project, providing a realistic and transparent view of the efficiency and payback achieved.
Together, these case studies highlight the consistent and proven impact of our retrofit packages across a range of real‑world applications.
