FläktGroup SEMCO

Precise Humidity & Energy Recovery for Critical EnvironmentsOur complete line of desiccant-based air treatment systems is engineered for applications where standard HVAC falls short. Whether you operate a low-temperature supermarket, a pharmaceutical lab, or an indoor vertical farm, excess humidity is your enemy. FläktGroup SEMCO's desiccant wheels and integrated systems actively remove moisture from the air, allowing you to maintain precise environmental control without overloading your cooling...

Cut HVAC Energy Costs by Up to 80% with SEMCO WheelsYour building's HVAC system is likely its largest energy expense. FläktGroup SEMCO energy recovery wheels are the most efficient way to slash that cost while maintaining superior ventilation. Our wheels capture sensible (temperature) and latent (humidity) energy from stale exhaust air and transfer it to fresh incoming air. In winter, you pre-heat and pre-humidify; in summer, you pre-cool and de-humidify.Our ElitePro series and other rotor techn...

Silent, Efficient Cooling for Commercial & Healthcare SpacesTraditional fan coils and VAV boxes are noisy and energy-hungry. FläktGroup SEMCO offers a better way: active and passive chilled beams. These ceiling-mounted units use the natural convection of water to cool (or heat) a space, requiring no fans. The result is absolutely silent operation – ideal for hospitals, open-plan offices, hotels, and educational lecture halls.Active chilled beams integrate with your primary air system to induce r...

We design and supply HVAC equipment for buildings where air quality, humidity and energy use really matter. Our work starts with listening to what the facility needs, whether that is humidity control for a lab, reliable cooling for a hospital, or a retrofit for an older system. From there we recommend the most cost-effective and energy-efficient configuration, and we back it with technical sales guidance, installation resources and quick-turnaround parts. Our engineers and product specialists wo...

Indoor air quality depends on controlling moisture, ventilation and the energy it takes to condition fresh air. Our systems are built to handle those together, using desiccant technology and energy recovery to keep humidity in range without overworking your cooling equipment. We model the climate and internal loads for your space before recommending a configuration, which may be a dedicated outdoor air system or a retrofit of an existing unit. The goal is cleaner, healthier air at predictable op...

Our energy recovery wheels capture heat and humidity from exhaust air and transfer it to incoming fresh air, so less energy is needed to condition the building. In winter the wheel pre-heats and pre-humidifies the supply air, and in summer it pre-cools and dehumidifies it. We offer the widest range of desiccant and sensible-only media, custom sizes, and OEM components for air handler makers. If an existing wheel is stuck or underperforming, our retrofit service can replace it with modern, low pr...

Chilled beams cool and heat a room using water rather than noisy fans, which makes them a good fit for hospitals, open-plan offices, hotels and lecture halls. Active beams work with your primary air system to draw room air across a water coil, while passive beams suit perimeter zones. Both can reduce air handler size and ductwork, which helps with first cost and ongoing maintenance. Our engineers fit the beam layout to your ceiling and load profile and coordinate with a dedicated outdoor air sys...

Noise from air handling equipment is a real concern in data centers, where fans and airflow run around the clock. Our duct silencers are designed to reduce that noise along the air path while keeping pressure drop low so cooling performance is not sacrificed. We size and select silencers to match the airflow and acoustic targets of your facility, whether you are fitting new equipment or addressing an existing noise problem. Tell us about your layout and equipment and we will help you find a conf...

Desiccant air treatment is for spaces where standard HVAC cannot hold humidity low enough, such as cold storage, pharmaceutical labs and indoor vertical farms. Our desiccant wheels and integrated systems actively remove moisture from the air, so your cooling coils do not have to work as hard to dehumidify. The same technology recovers energy from exhaust air, reducing the load on boilers and chillers. We model your climate and internal loads before selecting between a dedicated outdoor air syste...

We manufacture HVAC equipment with a focus on healthier indoor environments, combining the global engineering strength of FläktGroup with SEMCO's long history in desiccant-based air treatment. Our product lines include energy recovery wheels, desiccant systems, chilled beams and acoustic components, and we tailor them for data centers, hospitals, laboratories and other demanding sites. Because we design each product around a specific operating challenge, we can meet strict energy and sustainabil...

If you build or assemble air handling units, we supply the components and engineering support you need, including energy recovery wheels, custom panels and desiccant modules. We work closely with OEM customers to match component size, performance and mounting requirements to the unit they are building. Our engineers and product specialists understand the schedule pressures of production, so we focus on dependable lead times and clear technical documentation. Get in touch with your specifications...
