Sizes
There are 35 sizes available with 3,700 to 39,000 BTUH
at a 10° TD ranging from 740 to 4,980 cfm. One through
six fan models are available.
Housing
Rust-free, heavy gauge, textured Aluminum casing is light
weight yet durable. Each fan section is baffled to prevent
short cycling of the air. The unit is designed to mount flush
to the ceiling and meets all NSF requirements. Slotted
hangers are provided for easy installation. Drain fittings are
installed in the horizontal position to gain more usable headroom in low ceiling applications. The end panels now are
hinged to open up out for easy access to both the piping and
electrical ends. Optional expansion valves can be conveniently
installed inside the cabinet.
Coil
Seamless Copper tubes are staggered and mechanically
expanded into corrugated Aluminum fins and heavy gauge
tube sheets to achieve maximum heat transfer and strength.
Die formed fin collars provide even fin spacing. Fin spacings available are 4, 6, and 8 fins per inch. Sweat connections
are standard on all models and optional field installed flare
connection kits are available at no extra charge.
Motors
Standard motors are 1/20 HP, permanently lubricated, ball
bearing, with thermal overload protection. Available in 115V,
208/230V and 460V, single phase. Optional high efficiency
PSC and ECM motors are available in 115V and 230V.
Fans
Heavy duty 12” Aluminum fans are balanced to provide
vibration-free operation. Our new low throw black plastic
fan guards have an improved air pattern. The optional
epoxy resin high throw fan guard moves air up to 50 feet.
Air Defrost
All models with the prefix “HTA” are designed for use in coolers of 35°F and warmer. Complete air defrost systems for
off-cycle or timed air defrost are available.
Electrical
Available in 115V, 208/230V, and 460V (see pages 4 & 5). All
components are factory wired to convenient screw-type
terminal strips. A large compartment is supplied internal to
the unit for all electrical components and is easily accessible
by removing the end panel. All models are UL & cUL listed.
Electric Defrost
Available on all models with the prefix “HTE”. Designed for
use where electric heat is used to defrost. Placement of the
heaters internal to the coil allows for an extremely rapid and
efficient defrost. This arrangement enables the heat to be
conducted through the fins from the center out for an even
defrost pattern. All heaters are wired to a terminal strip to
allow a quick field change-over from single phase to three
phase, 230V to 460V and vice versa. A lower heater is
installed close to the drain pan for fast, reliable drainage. A
defrost termination thermostat (DT) terminates the defrost
cycle when the temperature is satisfied. A heater safety
thermostat is installed to prevent heaters from overheating
above 75° in case of DT failure. All heaters are flexible and
can be easily replaced within 12 inches of the end of the
units. A fan delay thermostat is supplied to allow the warm
coil to cool after a defrost cycle prior to the fans turning on.
Complete electric defrost refrigeration systems are available.
Features

(2) Drain connection on HTA and HTE units are centered on drain pan,
and on the left end (facing air discharge) on hot gas defrost units.
(3) For long air throw requirements, specify high throw fan guard.

Electric Defrost Kits
Electric defrost kits consist of components that are necessary to control the defrost cycle. The optional kits are available as a factory installed
option when ordered with a condensing unit. Not all Ed-Kits are available for all condensing unit models. The contents of each kit is described
below, along with the function of each component.
* - 1/2 through 3 HP models require ED-210 or ED-213.
Electric Defrost Kits
Timer: Initiates the defrost cycle. Also used as a over-
ride protection for defrost termination.
Auxiliary Switch: Is mounted on the compressor con-
tactor and prevents the defrost contactor from operating whenever the compressor is energized.
Block-Out Relay: Serves the same function as auxil-
iary switch. Used when defrost contactor is not
required (lower wattage single phase only).
Defrost Contactor: Carries amperage load for
heaters.
Fan Contactor: Used with 460V motors or when 230V
motors are wired 3 phase.
Sequencing Relays: Provides interconnection of multi-
ple unit coolers on a single system so that each
unit cooler is allowed to individually terminate
defrost on temperature.
¹ For use with 2 evaporators , 1/2 through 3 HP R-series systems ONLY!
