A Global Leader in Air Management

SEMCO® is a global leader in air management. SEMCO specializes in the design and manufacturing of a wide range of air climate and air movement solutions. Our constant aim is to provide systems that precisely deliver the best indoor air quality and performance, as well as maximize energy efficiency. We offer a complete line of desiccant-based products and systems that recover energy, increase ventilation and control humidity. Based on our patented EXCLU-SIEVE® technology, we provide the most cost effective solution to the dilemma facing designers as a result of ASHRAE 62; providing continuous ventilation while controlling humidity at any operating condition.

Energy Recovery Wheels

The SEMCO True 3Å Wheel has the industry’s highest recovery performance (AHRI Certified) and Recovery Efficiency Ratios (RER). Anti-corrosion, anti-microbial anti-stick face coatings are standard. This wheel is supported by an improved extruded aluminum structural hub, spokes and rim system. True 3Å  is available singly, in self-contained conditioning units, or as retrofits of existing wheels.

Air Treatment

EP- SEMCO’s EP Series offers the ultimate performance in the transfer of total energy (both latent and sensible). It is available as both a single (EP) or dual (EPD) wheel system. Pre-engineered and factory assembled, the EP Series system also provides the air handling capability for the building’s exhaust and supply air. The system can be selected to precondition outdoor air going to other conventional air handling systems or as an integrated system that provides total space conditioning with additional heating and cooling options available.


The ASCENDANT Series is ideal for hospital operating rooms, archival and dry storage, hotel/condo buildings, and other applications requiring low dew point temperatures and supply air humidity levels as low as 15 grains. ASCENDANT operates without the need for exhaust heat recovery, a feature making it ideal for applications requiring 100-percent outdoor air when exhaust air is unavailable for collection. ASCENDANT affirms SEMCO’s goal of delivering the best indoor air quality and performance, while maximizing energy efficiency.

PINNACLE Low Dew Point Delivery

Pinnacle manages 100% of a building’s ventilation and indoor humidity load in a single package, responding to varying conditions on demand. It cools, heats, or dehumidifies as required, providing a steady stream of optimally pre-conditioned, high quality, comfortable air.

Chilled Beams

IQHC is an intelligently designed active chilled beam that has the highest industry cooling capacity with the lowest air and water pressure drop.

The industry of chilled beams generally utilizes fixed nozzles, creating difficulties for design and commissioning with regards to air and pressure. SEMCO’s approach is to utilize adjustable nozzles, allowing the engineer to design around a single termination pressure. The test and balance contractor then has an easier time of system wide balancing to one pressure.
