2 Imroved Energy Efficiency & Reduced Sound Levels Three tiers of fan motor, fixed seed three hase A/C and VSEC (Variable Seed Electronically Commutated), are available to aid in reducing your energy consumtion to the otimum level: Fixed Seed AC A tried and true motor technology, offering a choice of three fixed seeds (54, 83, and 114 RPM) and corresonding caacities. Fixed seed motors are tyically aired with ressure switches to regulate head ressure in stages. The 54 RPM model rovides the lowest energy consumtion and sound levels, while the 114 RPM variation rovides maximum caacity er condenser surface area. The 83 RPM model offers lower sound levels and energy consumtion than the 114 RPM model, but greater caacity er condenser surface than the 54 RPM model. 2 Rail Mounted VSEC A new addition to the NTC latform, Rail Mounted VSEC is available in two eak seeds (83 and 114 RPM) with caacities that match their fixed seed counterarts. VSEC motors are controlled by either an onboard fan seed controller, adjusting fan seed to maintain a target head ressure, or by a user sulied inut signal (1V DC or 42mA). The advantage over a comarable caacity fixed seed motor is that the RPM of the fans can be adjusted almost infinitely to match the airflow requirements of the condenser. Venturi Mounted VSEC The remium VSEC otion for NTC condensers. Venturi Mounted VSEC fans come with modular fan and motor assemblies, comosite swet blade fans and are aired with a Venturistyle fan anel to otimize airflow and reduce sound at all RPMs. Steing u to a Venturi Mounted VSEC motor from a Rail Mounted VSEC motor rovides the ultimate in energy efficiency and sound reduction. 83 RPM Rail Mounted VSEC Models Meet California Title 24 For Efficiency

3 Simlicity. Flexibility. Variable seed without the comlexity Maximum efficiency, minimum sound and caacity when you need it Exclusivity. Reliability. Only from Heatcraft The highest quality, backed by industryleading warranties Worldwide Refrigeration VSEC MOTORS VSEC motors offer the lowest sound and highest energy efficiency in the industry. VSEC motor technology offers all the benefits of variable frequency drive (VFD) motors without the comlexity. VSEC motors modulate fan seeds, otimizing airflow for load requirements, minimizing energy consumtion and sound. VSEC motors are controlled by an otional, factory installed head ressure control system, or by a user sulied control signal.

5 Quiet, Innovative Efficiency The Cutting Edge Of Quiet QuietEdge Fan Technology The Heatcraft atented QuietEdge technology uses secially designed swet fan blades to reduce noise levels. These blades are uniquely designed for each motor seed, otimizing erformance and ensuring you are receiving the lowest sound levels ossible. QuietEdge is available with four blades on 54 RPM models and five blades on 83 RPM (1.HP) motors. Advanced Features and Engineering Common Sound Levels City Traffic 9 dba 9 Service Ease Motor Mount This system enables one service technician to remove and relace the motor, while reducing the risk of damaging the coil. 114 RPM Condenser 81 dba 7 6 Normal conversation 6 dba VSEC Condenser 56 dba Refrigerantcarrying coer tubes float through oversized holes in the tube sheet and are exanded into the aluminum fins, minimizing wear and virtually eliminating the ossibility of tube sheet leaks. Additional fixed tubes are designed into the tube sheet to suort the weight of the coil. A hinged Venturi otion allows for easy maintenance and servicing of the condenser. The Venturi can effortlessly be lifted by one service technician and latched for safety to allow for maintenance activities such as cleaning the unit.
