DESCRIPTION

This unique modular system allows the flexibility to handle any
application. These versatile MVC blowers may be used for
upflow, downflow, or horizontal left or right applications. They
may be combined with cased coils to function as a cooling only
unit or with a heat pump including electric heat for 1 and 3
phase applications.

FEATURES

COMMON MVC AIR HANDLER AND MATCH-UP CM COIL
Rigid Case Construction - An interior endoskeleton for
structural support, smooth side, and locks in insulation.
Powder-painted - G30 galvanized steel case provide a coated
edge that resists corrosion and rust creep.
Quality Construction - Structural components are made of
Aluminum or G90 galvanized steel to prevent corrosion.
Improved Insulation Design - Single piece with no external
screws to reduce thermal transmission paths to prevent
sweating. Foil faced insulation for ease of cleaning.
Case Depth - These models have 20.5" casing which provide
ease of attic access and tight applications.
MVC AIR HANDLERS
Factory Sealed - Achieves 2% or less total airflow leakage rate
at duct leakage test conditions in positive and negative
pressure for system airflow verification.
Electric Heat Kits - 6HK series of field installed electric heat
kits are available for installation-friendly and easy service
applications.
Blowers - All models use direct-drive, variable speed ECM
motors.
CM COILS
TM
Coil - Long life aluminum coils built to deliver
MaxAlloy
lasting performance, efficiency and reliability.
Thermostatic Expansion Valve - The accessory bolt-on TXV
provides easy installation to convert the indoor coil to the
required refrigerant that does not require brazing to replace or
install. Some models are available with factory installed TXV.
Thermoset Drain Pan - Low retention and positive slope for
drainage to reduce potential mold or contaminants.
Accessories - A full line of matching accessories available for
use with the blower and coils to provide for any type of
application.
