DESCRIPTION
This unique modular system allows the flexibility to handle any
application. These versatile coils and blowers may be used for
upflow, down-flow, or horizontal left or right applications. They
may be combined to function as a cooling only unit or with a
heat pump including electric heat for 1 and 3 phase applications. The blower and electric heater could be used as stand
alone electric furnaces.
FEATURES
Blowers - Models to match any air flow or voltage requirement.
The compact size allows easy installation. Blowers are sized to
deliver design air quantity both efficiently and quietly. The
direct-drive, multi-speed blower motors provide a selection of
air quantities to match any application. All models include a
one-minute blower off delay as standard to enhance system
efficiency ratings. The durable, pre-painted steel protects the
unit against rust and corrosion. All models have 1 inch foil face
fiber glass insulation, providing a thermal insulation value of R-
4.2.
Coils - Staggered rows of rifled copper tubes are mechanically
expanded into enhanced surface aluminum fins to provide high
heat transfer and long-lasting quality. The MC multi-position
coils may be used for upflow, downflow, and horizontal left or
right applications. Coil cabinets are insulated with 3/4" fo il face
insulation to prevent sweating.
Thermal Expansion Valves - Coils are ordered as “Flex-coil”
unit without a factory installed mertering device. Flex-coil models allow for field installed R-22 or R-410A TXV’s for added flexibility to meet refrigerant system choice.
Electric Heaters - Both single and three phase el ectric heater
models are available to match any requirement. All heaters
include nickel-chromium elements with a 5-year limited warranty on 1 Ø heating elements and 1 yea r li mi ted wa rranty on 3
Ø heating elements. Sequential operation is provided to control
heaters in all models. Circuit breakers are used in 208/230 volt,
single-phase heaters of 15 KW and larger.
Models equipped with circuit breakers may be altered in the
field to use multi-source power supply. Over-temperature limit
switches provide protection from airflow loss with fusible link
backup protection.
NOTE: No heat kits are available for 115 Volt models.
Accessories - A full line of matching accessories a vailable for
use with the blower and coils to allow any type application.
LIMITATIONS
These units must be wired and installed in accordance with all
national and local safety codes.
