SA Series

Performance

Increase performance with heat pump configurations which can heat the air as energy efficiently as it cools it. By transferring heat from water or air to the building, the SA Series heat pump requires no fossil fuels.

Quality

• Two-inch double wall rigid polyurethane foam panel cabinet construction has at least a thermal resistance of R-13, which exceeds the R-value of a cabinet with four-inch thick fiberglass construction. Panels include a thermal break, with no metal contact from inside to outside, to prevent heat transfer through the panel and prevent condensation on the outside of the cabinet. The inner wall protects the insulation from moisture damage, prevents microbial growth and is easy to clean. This type of construction also makes the cabinet more rigid and resistant to damage, provides increased sound dampening, and reduces air leakage and infiltration
• Modular design with compact footprint makes the SA Series ideal for retrofit applications. Single or double-sided air intake
• Access doors with full-length stainless steel hinges and quarter-turn, zinc cast, lockable handles make the unit easily serviceable
• Corrosion-resistant exterior polyurethane paint exceeds a 2,500-hour salt spray test
• Double-sloped stainless steel drain pans eliminate standing water which can support microbial growth and stainless steel construction prevents corrosion that could lead to water leaks and contaminants in the air stream

• Long lasting designs with standard features like corrosion-resistant exterior polyurethane paint exceeds a 2,500-hour salt spray test and optional Interior corrosion protection option for corrosive environments
• Backed by some of best warranties in the industry like compressors including a five year non-prorated warranty

Features

• Spring isolated direct drive backward curved plenum fans are more energy efficient, quieter and require less maintenance than belt-driven fans
• Single or multiple supply air connections can be factory provided from the right, left, back or top sides of the supply fan plenum
• VFD (Variable Frequency Drive) controlled direct drive backward curved plenum supply fans allow precise airflow control and reduced power consumption
• Labeled electrical components and color-coded wiring match the unit-specific color-coded wiring diagram which is laminated and permanently affixed inside the control compartment
• Factory provided or customer provided controller can be selected to meet existing or new building control architecture
• Unit control and compressors are contained within a single compartment isolated from the air stream for ease of service and quiet operation
• Factory run test report, wiring diagram and Installation, Operation, and Maintenance manual with startup form are provided in the control compartment of every unit
• Multiple high-efficiency filtration options, with up to a MERV 14 efficiency rating
• Modulating humidity control provides energy-efficient dehumidification, even with low sensible heat loads, without the temperature swings common with on/off reheat systems

Options

• With 10-100% capacity control, variable capacity scroll compressors can match the load needed by the unit The compressors vary the volume of refrigerant that flows through the cooling system allowing the unit to tightly control the air temperature and save energy when the unit is not running at full load
• Factory installed constant or variable flow waterside economizer allows for free cooling at low ambient conditions
• Shell and tube or brazed plate refrigerant-to-water heat exchangers provide energy efficient heat transfer
• Polymer e-coated coils are available to extend the life of the coils and protect them in corrosive environments
• Interior corrosion protection option for corrosive environments

• Vertical self-contained unit with a water-cooled condenser or to match with a remote air-cooled condenser, from 23-70 tons
• Chilled water or non-compressorized DX vertical indoor air handling unit, from 5,300-27,000 cfm
• 10-100% variable capacity scroll compressors provide load matching cooling and improved part load efficiency
• Air-source, water-source, or geothermal heat pump configurations allow for energy-efficient cooling and heating
• Make-up air capability, up to 100% outside air, to meet ventilation requirements
• High-performance hot water or steam heating coils allow unit to tie into a boiler system
• Natatorium and Pool Room Units; AAONDry units are essential in creating a comfortable indoor pool environment, by precisely controlling temperature and humidity, while minimizing operating costs
