SB Series

Applications

• Water-source and geothermal heat pump vertical self contained unit, from 3-18 tons.
• Remote air-cooled condenser and air-source heat pump configurations.
• 10-100% variable capacity R-410A scroll compressors provide load matching cooling and heating and improved part load efficiency.
• Make up air capability, up to 100% outside air, to meet ventilation requirements.
• VAV and single zone VAV applications to minimize system operation costs.
• Factory installed high performance electric, hot water, or steam heating.

Construction

• Double wall rigid polyurethane foam injected panel cabinet construction has a higher thermal resistance, or R-value, compared with 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. Construction also makes the cabinet more rigid and resistant to damage, provides increased sound dampening, and reduces air leakage and infiltration.
• Compact cabinet design provides easy installation at the job site.  The compressorized section can be factory assembled to the air tunnel to prevent unnecessary work at the job site or it can be shipped separate from the air tunnel to allow the two sections to fit through a standard 36in doorway.
• Access doors with chrome plated steel hinges and quarter turn, lockable handles make the unit easily serviceable.
• Double sloped stainless steel drain pans eliminate standing water which can support microbial growth and stainless steel construction resists corrosion that could lead to water leaks and contaminants in the air stream.
• Foam insulated, thermally isolated coaxial refrigerant-to-water heat exchangers provide energy efficient heat transfer with lower water side pressure drops.

Fans

• Direct drive backward curved plenum fans are more energy efficient, quieter, and require less maintenance than belt driven fans.
• ECM (Electronically Commutated Motor) driven direct drive backward curved plenum supply fans are available to provide precise airflow control and reduced power consumption.

Controls

• 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 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.

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.
• Double wall rigid polyurethane foam injected panel construction, stainless steel condensate drain pans, polymer e-coated coils, and exterior and interior corrosion protection protect components of an SB Series AAONDry unit in corrosive environments. Modulating humidity control provides energy efficient dehumidification. Variable speed supply fans and variable capacity compressors save energy.

• 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.
• Modulating humidity control provides energy efficient dehumidification, even with low sensible heat loads, without the temperature swings common with on/off reheat systems.
• Mixing boxes available that include either on/off dampers, modulating dampers, or fixed position dampers on the outside air and return air streams and can be factory wired to allow for economizer operation.
• Multiple high efficiency filtration options, with up to a MERV 14 efficiency rating.
• SCR (Silicon Controlled Rectifier) electric heat control for reduced power consumption, longer heater life and improved occupant comfort.
• Polymer e-coated coils, copper finned coils, and stainless steel coil casings are available to extend the life of the coils and protect them in corrosive environments.
• Interior and exterior corrosion protection is available to protect the cabinet in corrosive environments.
