COMPRESSOR: Copeland K-5 Scroll� or LG rotary (single
speed) and Copeland Scroll UltraTech� (dual capacity) in
commercial voltages mounted on a double isolation system.
WATER LINES: Copper FPT waterline connections, securely
mounted flush to cabinet corner post.
COAXIAL HEAT EXCHANGER: Oversized and convoluted with
copper inner tube (optional cupronickel) and steel outer tube,
designed for maximum heat transfer at normal and low water
flow rates to minimize pressure drop.
ALUMINUM AIR COIL: An aluminum air coil is featured in all
Versatec 500 units to provide exceptional durability and high
efficiencies. Added protection is also available with an optional
AlumiSeal� coating.
CABINET: The cabinets utilize a compact form and are
constructed of heavy gauge environmentally responsible
galvanized steel for maximum corrosion resistance. Units are
available with a durable white powder coat finish or unpainted.
All interior surfaces are lined with 1/2" thick, foil lined acoustic
type fiber insulation, applied in a manner that prevents the
introduction of glass fibers into the air stream. Multiple knockouts
in various sizes facilitate power and low voltage wiring.
REFRIGERANT CIRCUIT: Units utilize low GWP refrigerant in
sealed circuits. Metering accomplished with a bi-flow thermostatic
expansion valve to deliver optimum flow over a wide range of
conditions without troublesome check valves. Four-way solenoid
activated reversing valve defaults to heating and is �cool brazed� at
the factory.
FILTER RACK/RAIL: Redesigned filter rack includes a standard
1" filter rail with a MERV 4 filter. Options include a 1" or 2" foursided filter rack suitable for ducted applications, or a 2" filter rail
with MERV 13 filters for non-ducted applications.
CONTROLS: Aurora Base Control is standard. Optional
Universal Protocol Converter featuring N2 and
BACnet compatibility.
BLOWER MOTOR: Blower motors provide high efficiency while
allowing quiet operation and wide range of airflow selections.
Optional 5-Speed ECM and variable speed ECM blower motors
are available for improved efficiency and comfort.
FLOW REGULATOR: Optional factory installed internal water
flow regulator.
WATER VALVE: Optional factory installed internal 24V on/off
2-way water valve for VFD pumping applications.
HOT WATER GENERATOR: Optional factory installed heat
exchanger with field mounted external pump.
