Energy Recovery Wheel - Overview INDOOR AIR QUALITY ENERGY RECOVERY FLUTED WHEEL MEDIA UNITARY WHEEL CASSETTE UWC / UWCH UWC/UWCH KEY BENEFITS Independently tested & AHRI certified wheel performance High Enthalpy Performance = Less Pressure Loss, Less Fan Energy, More Energy Savings, Low operating costs The SEMCO Unitary Wheel Cassette (UWC) Series, a sensible and latent energy recovery aluminum desiccant wheel, is designed and packaged as the HVAC industry s first drop in replacement for most OEM wheels used by packaged rooftop unit manufacturers. Use of the AHRI Certified mark indicates a manufacturer s participation in the certification program. For verification of certification for individual products, go to www.ahrinet.org. High latent AND sensible heat transfer efficiencies Highest Recovery Efficiency Ratios (RER) available in the industry Industry-leading indoor air quality device through minimized desiccant cross contamination Integrated purge section option Wheel independently certified to pass NFPA 90A requirements for flame spread and smoke generation and ASTM E84 fire test method Proven reliable operation The UWC Series 3-3/4-inch-wide (100-mm) wheels feature a fast-acting, corrosion-resistant, proprietary desiccant that s applied to a sturdy, but lightweight all-aluminum wheel substrate. The honeycomb matrix s fluted opening design efficiently produces maximum latent and sensible air-to-air heat transfer, but generates up to 50-percent less HVAC system static pressure than polymer film wheels. Besides assisting buildings in surpassing ASHRAE 90.1 building energy compliance, the aluminum wheels also have longer life cycles and vastly less periodic maintenance requirements than polymer wheels and can withstand temperatures of up to 180 F. Low maintenance Proven long life expectancy 8 Controls Options

These systems are typically 100% outdoor air. MC-3/5/7000P - Space Primary The MC-3/5/7000P control sequence provides temperature and humidity control of a single zone. This control sequence is applied for high percentage outdoor air situations (>20% OA) where a single unit is required to meet both the outdoor air requirement, as well as, controlling the space temperature. MC-3/5/7000V - Variable Air Volume (VAV) The MC-3/5/7000V control sequence is a variable air volume sequence intended to provide a constant supply air temperature and vary fan speed according to the system static pressure for units with high percentage outdoor air (>20% OA) where the ability to maintain dehumidification while resetting the supply air temperature is a concern. It serves multiple zones where each zone is provided with a VAV box with reheat. MC-3/5/7000Z - Single Zone VAV The MC-3/5/7000Z control sequence is a variable volume control sequence which provides temperature and humidity control of a single zone. Both the fan speed and supply air temperature will vary according to the requirements of the single zone. The outdoor air percentage should be no greater than 20%. Controls Options 9

Electrical Data - Nameplate Calculation Examples Nameplate Single Point Power Calculation: 1.1 a) FLA (full load amps) Calculation: For A/C only units, Add up the FLA s (or RLA s) of Each Compressor, Supply Fan, Condenser Fan, and if applicable Exhaust Fan & Electric Preheat. This number will be your Nameplate FLA. For A/C only units with Electric Post/Primary Heat, add up the FLA s of the Electric Post/Primary Heater, Supply Fan(s), and if applicable Exhaust Fan(s) & Electric Preheat. Compare the Two Calculated FLA s... the Largest will be the Unit Nameplate FLA. For Heat Pump Systems with Post/Auxiliary Electric Heat, Add up the FLA s (or RLA s) of Each Compressor, Post/Auxiliary Electric Heat, Supply Fan, Condenser Fan, and if applicable Exhaust Fan & Electric Preheat. This number will be your Nameplate FLA. 1.1 b) MCA (minimum circuit amps/wire size) Calculation: For A/C only units, multiply the Lead Digital Scroll Compressor RLA by 1.25 and then add the remaining FLA (or RLA) of all other components including the Fixed Speed Scroll half of each Tandem Scroll Compressor. This number will be your Nameplate MCA. For A/C Only Units w/ Electric Heat, multiply 125% times the sum of each of the FLA s for the Electric Post/Primary Heater, Supply Fan(s), and if applicable Exhaust Fan(s) & Electric Preheat. Compare the Two Calculated A/C only unit MCA s... the Largest will be the Unit Nameplate MCA. For Heat Pump Systems with Post/Auxiliary Electric Heat, multiply the Lead Digital Scroll Compressor RLA by 1.25 and the Post/Auxiliary Electric Heat FLA by 1.25 then add the remaining FLA (or RLA) of all other components including the Fixed Speed Scroll half of each Tandem Scroll Compressor. This number will be your Nameplate MCA. 1.1 c) MOP (maximum overcurrent protection) Calculation: For A/C only units, multiply the Lead Digital Scroll Compressor RLA by 2.25 and then add the remaining FLA (or RLA) of all other components including the Fixed Speed Scroll half of each Tandem Scroll Compressor. This number is your calculated MOP. Take this number and round down to the next lowest standard fuse size for your Nameplate MOP. For A/C Only Units w/ Electric Heat, multiply the sum of the Supply Fan(s) FLA by 2.25 and then add the remaining FLA of all other components including Electric Heaters, however, excluding the RLA of Compressor(s) and Condenser Fan(s). Compare the Two Calculated A/C only unit MOP s with & without Electric Heat... the Largest will be the unit calculated MOP. Take this number and round down to the next lowest standard fuse size for your Nameplate MOP (round up to the next highest standard fuse size if your largest calculated MOP is less than your largest calculated MCA.) For Heat Pump Systems with Post/Auxiliary Electric Heat, multiply the Lead Digital Scroll Compressor RLA by 2.25 and then add the remaining FLA (or RLA) of all other components including the Fixed Speed Scroll half of each Tandem Scroll Compressor & the Post/Auxiliary Electric Heat FLA. Take this number and round down to the next lowest standard fuse size for your Nameplate MOP (round up to the next highest standard fuse size if your largest calculated MOP is less than your largest calculated MCA.)
