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 applica-
tions. 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" foil face
insulation to prevent sweating.

Thermal Expansion Valves - 

Available with R-22 or R-410A

factory installed TXV’s. Air Handlers maybe 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 electric heater

models are available to match any requirement. All heaters
include nickel-chromium elements with a 5-year limited war-
ranty on 1 Ø heating elements and 1 year limited warranty 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 available 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.
