Energy Recovery Systems

SEMCO’s FreshAir (FV) Series ventilator outdoor air pre-conditioners are designed for applications where continuous fresh air ventilation is essential. This series provides efficient energy recovery by transferring heat and moisture between the exhaust and supply air streams, ensuring optimal indoor air quality and reduced energy costs. The FV series units are known for their robust construction, reliable performance, and adaptability to various building ventilation needs.

• Air Flow Range: 600 – 10,000 CFM
• Dew Point: 52 – 55
• Grains of Moisture: 58 – 65
• Energy Cost Savings: $8,500/year
• Humidity Control: 57% – 62%

FV series ventilators affordably lower the operating cost of a building designed in accordance with the ASHRAE indoor air quality standard.

The Pinnacle Series (PVS) is SEMCO’s premier product line that combines advanced desiccant-based energy recovery with dehumidification capabilities. This series is ideal for climates requiring precise humidity control while maximizing energy savings. The PVS units offer superior performance by integrating sensible and latent energy recovery with dedicated outdoor air system (DOAS) technology to maintain desired indoor conditions efficiently.

• Air Flow Range: 1,500 – 45,000 CFM
• Dew Point: 40 – 48
• Grains of Moisture: 38 – 51
• Energy Cost Savings: $35,150/year
• Humidity Control: 40% – 50%

The Pinnacle Series responds to various combinations of temperature and humidity by modulating the passive dehumidification wheel and the cooling coil. It then provides a constant stream of optimally conditioned ventilation air while exhausting stale, polluted air. This happens in a highly efficient manner, providing substantial operating savings by eliminating the need for conventional over-cooling and reheat systems. Optimizing the condition of your building’s supply air, the Pinnacle Series reduces demand for overall heating/cooling capacity, and provides substantial savings in installation costs.

Pinnacle I is able to dehumidify outdoor air as low as 40 grains – dewpoints unattainable with conventional systems. It consists of a supply fan, exhaust fan, total energy recovery wheel, a cooling coil, and a passive dehumidification wheel.

Pinnacle II expands the Pinnacle Series dehumidification capabilities and optimizes temperature control. It is able to dehumidify outdoor air as low as 35 grains and features the same components as the Pinnacle I, but also incorporates a second DX trim coil with a variable speed compressor.

The Pinnacle can recover up to 90% of the heating energy from a building’s exhaust air stream during its heating mode.

This system offers the ultimate performance in the transfer of total energy, and is available as a single (EP) or dual (EPD) wheel system. The pre-engineered and factory assembled EP series provides air handling capability for exhaust and supply air. The system can precondition outdoor air going to other conventional air handling systems or be used as an integrated system, providing total space conditioning with additional heating and cooling options available.

• Air Flow Range: 2,000 – 70,000 SCFM
• Dew Point: 50 – 58
• Grains of Moisture: 50 – 65
• Energy Cost Savings: $11,450/year
• Humidity Control: 54% – 62%

The EP Series has a technologically advanced wheel with a 3Å molecular sieve-desiccant coating that is selective in what it adsorbs from an exhaust air stream. The desiccant rejects airborne contaminants while it transfers water vapor. This results in providing total energy transfer from the exhaust to the supply air stream. This very important and unique feature has been well documented through independent laboratory and field-testing. Selectivity allows the wheel to be used in critical applications, including recovery from contaminated air streams.

The Elite Series (ELT) is designed for high-efficiency energy recovery, focusing on advanced air-to-air heat and moisture transfer. The ELT units use enthalpy wheels to effectively recover and recycle energy from exhaust air, contributing to substantial energy savings and improved indoor air quality. This series is designed for buildings that require rigorous energy performance while maintaining comfort standards.

• Air Flow Range: 3,500 – 20,000 CFM
• Dew Point: 52 – 55
• Grains of Moisture: 57 – 65
• Energy Cost Savings: $9,800/year
Humidity Control: 57% – 62%

The Elite features the Unitary Wheel Cassette (UWC), offering superior performance with the highest latent and sensible heat transfer efficiency media on the market, in its class. The UWC can be installed quickly and easily, as a slide-in replacement for similar fiber wheels and dimpled plastic wheels.

Designed and built to have a long, reliable, and relatively maintenance-free life, the UWC is AHRI certified, which verifies that the cassettes will perform accurately and consistently, in accordance with ASHRAE Standard 84. In addition to ASHRAE Standard 84, the UWC is independently certified to pass NFPA 90 requirements for flame spread and smoke generation based upon ASTM E84 fire test method.

The Elite Series also includes high performance EC fans, designed to minimize noise and optimize system efficiency for superior energy and cost savings.
