Environmentally Friendly & Low GWP Refrigerant

Rebel Applied's heat pump technology uses electricity to move heat, resulting in lower carbon emissions and a more environmentally friendly heating and cooling solution. Government financial incentives are available for adopting this technology.

The system utilizes advanced variable speed compressors and electronic commutated motor fans for precise temperature control and minimized energy waste, ensuring optimal performance and sustainable operation.

Low GWP Refrigerant: With a GWP of 675, R-32 contributes less to global warming potential compared to R-410A. R-32 systems can use up to 40% less refrigerant charge. As a pure, single-component refrigerant, R-32 retains its quality over time, is easy to clean and reuse on-site, and can be reclaimed and recycled simply.

Industry-Leading Performance: Surpassing competitors with an exceptional EER of 11.0 and Class 6 air leakage rating at +/-6 static pressure, Rebel Applied achieves optimum cooling performance while consuming significantly less energy. This translates into substantial cost savings and a reduced carbon footprint.

The 20.0 IEER showcases unparalleled energy efficiency across a wide range of operating conditions, making Rebel Applied suitable for diverse applications from small office spaces to large-scale commercial buildings.

Sustainable Heat Pumps for Cold Climate Applications

Direct Expansion (DX) Heat Pump: Highly energy-efficient, transferring heat between spaces. This process requires significantly less energy than traditional heating systems like electric resistance heaters or fossil fuel furnaces, reducing greenhouse gas emissions and carbon footprint.

Conventional heat pumps struggle in cold climates, often requiring large, inefficient electric heaters for supplemental heat. Rebel Applied's high output heat pump utilizes boost compression to increase heating capacity in cold conditions, with remaining heat load supplemented by a gas or electric source.

Benefits: High efficiency heat transfer, compact design for ease of installation, flexible zoning and individual temperature control, reduced noise levels, and durable operation.

Unlimited Packaged Configurability & Split Condensing Systems

With a groundbreaking 37% shorter and 20% lighter design, Rebel Applied units enable flexible installation in tight spaces, ideal for new installations and retrofit projects. This compactness saves valuable real estate, simplifies logistics, and reduces project timelines and costs. The reduced weight minimizes structural requirements for easier rooftop placement.

Easy Retrofit: Rebel Applied's modular solution offers unparalleled flexibility. A no-transition curb ensures hassle-free integration, eliminating costly modifications or extensive downtime. Units can seamlessly replace Daikin or other rooftop units.

Inverter Scroll Compressors: Daikin inverter compressors operate at variable speeds, making them energy-efficient. They adjust power output according to cooling requirements, consuming only necessary energy for significant savings. This provides precision air temperature and humidity control.

Putting the IQ in IAQ (Indoor Air Quality)

Daikin technologies focus on ventilation that maximizes effective clean air changes with the lowest energy consumption, addressing common IAQ issues like CO2 generated by occupants and volatile organic compounds (VOCs) from building materials.

Sorbent Ventilation Technology (SVT): Tested in accordance with ASHRAE 145.2, SVT removes CO2, VOCs, and other contaminants using sorbent filtration. When applied using ASHRAE 62.1's IAQ Procedure (IAQP), SVT provides cleaner air and reduces HVAC energy use by up to 30%. It offers a sustainable decarbonization solution by reducing outdoor air intake and indirect carbon emissions.

Pathogen Mitigation:

Photo-Catalytic-Oxidation (PCO): UVGI photons react with a Titanium Oxide (TiO2) mesh panel to create hydroxyl radicals that oxidize gaseous organic compounds, reducing them to trace compounds, CO2, and H2O.
Filtration: Configurable filtration with cartridge filters up to MERV 16 and HEPA final filters. High efficiency filtration is key to reducing infection risk from airborne pathogens.
Ultra-Violet Germicidal Irradiation (UVGI): Factory-mounted UV lights are available for coil cleaning or airstream disinfection to deactivate airborne pathogens.
