Radiant climate ceilings: silent, draught-free comfort with low-temp, renewable-ready performance and minimal maintenance.Effortless indoor comfort starts at the ceiling.
vektron climate ceilings deliver silent, draught-free heating and cooling through radiant exchange and gentle convection, creating a healthy, clean indoor environment. Designed to integrate seamlessly with lighting, ventilation, audio and sensors, our systems combine design discretion with technical excellence for future-ready buildings.
Indoor climate comfort: how radiant systems work
Summer: gentle coolness without draughts
In cooling mode, the chilled ceiling performs in two complementary ways:
- Radiant CoolingHeat from people, surfaces and furnishings radiates to the cooler ceiling surface, which absorbs excess heat-creating a stable, comfortable coolness.
- Convection CoolingAmbient air gently circulates as it contacts the cooler ceiling surface, lowering room air temperature evenly across the entire ceiling area.
Because the cooling effect is distributed over the full ceiling, occupants experience high thermal comfort with no draughts and near-silent operation.
Winter: radiant heating where it matters
For heating, low-temperature hot water flows through integrated copper tubes, warming the ceiling surface. The ceiling then radiates heat directly to people and surfaces: floors, walls, furniture without over-heating the air volume.
This direct, radiant transfer increases perceived comfort and reduces stratification, achieving balanced warmth at lower energy input.
Sustainability & health: environmentally friendly by design
Cooling
Forward line temperatures of 17–19 °C
Heating
Water temperatures of 30–40 °C
No fans
Cuts electric consumption, reduces noise and airborne dust.
Materials
The surface heat-exchanger uses fully recyclable copper and aluminium.
Optimized use of materials
A patented ‘WLT’ design maximizes energy transfer while minimizing raw material use.
Heat exchanging technology: the engine of high performance
Our patented heat-exchanger is engineered for maximum output at low energy input.
How it works:
- D-shaped copper tubeThe tube is formed into a patented D-profile to increase contact area with the ceiling panel—improving conductive transfer.
- Aluminium thermal conductorA seamless aluminium jacket wraps the copper tube, optimizing heat spread across the panel for superfast response and uniform surface temperatures.
Result: A super-conductive, ultra-fast heat-exchanger that delivers low energy consumption, stable comfort, and renewable-ready performance.
Renewables & ATES: seasonal intelligence
Compatible with heat pumps
Thanks to low supply temperatures, vektron climate ceilings are ideal partners for air-to-water and ground-source heat pumps, maintaining high COPs and stable comfort year-round.
Aquifer seasonal thermal energy storage (ATES)
ATES stores thermal energy in an underground aquifer through a two-well system:
- Cold well for cooling season, hot well for heating season
- A heat-exchanger isolates groundwater from the building circuit—preventing contamination and protecting equipment
- Summer: cold water supports building cooling; excess heat is stored in the hot well
- Winter: warm water supports heating; cooled water returns to the cold wellThis seasonal cycle dramatically improves building energy efficiency.
FAQ's
Does radiant cooling cause condensation?
With correct design and controls (dew point monitoring and ventilation integration), surface temperatures stay above dew point, preventing condensation.
How does radiant comfort compare to forced air?
Radiant systems offer stable temperatures and no draughts, improving perceived comfort and acoustic quality.
Can I retrofit climate ceilings?
Yes—modular panels allow phased upgrades. Integration with existing hydronic systems and heat pumps is common.
What control strategies are recommended?
Use low-temp supply, zone valves, surface and room sensors, and dew point safety. BMS integration ensures predictive, efficient operation.
