Engineered for Modern Mechanical Design
From Concept to Commissioning
Modern ventilation design requires flexibility, control, and dependable performance across a wide range of building conditions. SENSE CX and SENSE FX are engineered to simplify that process, delivering adaptable energy recovery solutions for decentralized (CX) and ceiling-mounted (FX) applications.
For Mechanical Engineers
SENSE CX and SENSE FX deliver high-efficiency enthalpy energy recovery (SENSE CX up to 59% | SENSE FX up to 63%), demand-controlled ventilation strategies, and BAS integration to support ASHRAE standards and high-performance goals such as LEED, Passive House, and Net Zero design.
For Mechanical Contractors
Compact footprints, flexible configurations, and installation-ready designs help reduce complexity on site and streamline installation and commissioning.
Note re: latent efficiency: based on minimum speed 300 m3/h = 177 cfm; for humidity efficiency - outdoor air temperature is 41°F (+5°C), relative humidity 72%, indoor air temperature is 77°F (+25°C), relative humidity 51 %; for humidity efficiency - outdoor air temperature is 41°F (+5°C), relative humidity 72%, indoor air temperature is 77°F (+25°C), relative humidity 28 %
