3-3

The compressor shall be complete

with charging and service schraeder

ports, internal vibration isolation,

internal thermal overloads, internal

pressure relief valve, internal dis-

charge gas vibration eliminator and

external vibration mounting isolation.

Chilled Water Systems

(Models OHS-()-C)

Cooling Coil:

The chilled water coil shall be con-

structed of seamless drawn copper

tubes, mechanically bonded to tem-

pered aluminum ﬁns for maximum

heat transfer. Coil end plates shall be

hot dipped galvanized.

The cooling coil shall be mounted in

an insulated stainless steel conden-

sate drain pan.

Control Valve:

Cooling capacity shall be controlled

by a factory installed slowly opening

and slowly closing 2-way motorized

control valve rated for a maximum

300 psig w.w.p.

(Note: Please refer to page 3-10 for ad-

ditional chilled water valve options.)

Blowers / Motors

Direct Drive Systems

The blower(s) shall be direct driven

with double width, double inlet hous-

ing and forward curved blades. The

blower(s) shall be dynamically and

statically balanced to minimize vibra-

tion and operate in the Class I range.

The blower(s) shall be corrosion

protected with a painted housing and

impeller wheel.

The three speed (208V) evaporator

motor shall be factory wired for the

correct speed to produce the speci

-

ﬁed air quantity. The motor(s) shall

have internal overload protection.

(277V & 460V direct-drive motors shall be

2-speed.)

Belt Driven Systems

The blower(s) shall be belt driven with

double width, double inlet hous-

ing and forward curved blades and

permanently lubricated ball bearings

sized for an average 100,000 hours

of service life. The blowers shall be

dynamically and statically balanced to

minimize vibration and operate in the

Class I range.

The blower(s) shall have an adjust-

able base for belt tensioning and a

locking system to prevent the mo-

tors from moving. The motors’ drive

sheaves shall have an adjustable pitch

to change the speed of the blowers.

The motor(s) shall be 1725 RPM and

shall have overload protection and

a minimum NEMA service factor of

1.15.

Temp & Humid Control

The standard CeilAiR system is con-

ﬁgured as a "cooling only" system.

Heating, reheating and/or humidity

control can be optionally added to

provide total space temperature and

humidity control. (Please see pages

3-5 thru 3-7 for more details.)
