System Components

Chilled Water Cooling Coil:

The coil shall be constructed of seamless drawn copper tubes, mechanically bonded to tempered aluminum fins with a fin design for maximum heat transfer, and mounted in a condensate drain pan. The coil shall be designed for under 500 ft/min face velocity. The water circuit shall be designed to distribute water into the entire coil face area

CW Control Valve:

The water circuit shall include a factory mounted, 2-way modulat-ing control valve. Design pressure shall be 600 psig. Note: 3-way valves are optional.

Blowers / Motors

Belt-Driven Systems

The blower(s) shall be belt driven with a double-width, double-inlet housing and forward-curved blades and permanently lubricated ball bearings sized for a minimum life span of 100,000 hours of service life (L10 Life). The blower(s) shall be dynamically and statically bal-

anced to minimize vibration and oper-ate in the Class 1 operating range. The blower(s) shall be corrosion protected. The blower(s) shall be belt driven with dual belts sized for 200% of the fan motor horsepower. The blower shall have an adjustable base for belt ten-sioning and a locking system to prevent the motors from moving. The motor’s drive sheaves shall have an adjustable pitch to change the speed of the blow-ers. The motor shall be 1725 rpm and shall have overload protection and a minimum NEMA service factor of 1.15.

HUMIDITY CONTROL:

The humidifier shall be of a self-con-tained steam generating electrode type utilizing a plastic disposable cylinder with full probes connected to electric power via electrode screw connectors. The electrodes shall be constructed from expanded low car-bon steel, zinc plated and dynamically formed for precise current control. The humidifier assembly shall include integral fill cup, fill and drain valves and associated piping.The canister shall be designed to col-lect the mineral deposits in the water and provide clean particle free steam to the air stream, thereby reducing maintenance cost.

The microprocessor control shall main-tain humidifier operation through fill and drain cycles based on the water conductivity. Overflow and loss of flow protection shall be provided

along with a manual drain switch. A high water alarm with built-in time delay shall provide an indication to change canister. The humidification system shall require no cleaning main-tenance during the cylinder life.

The humidifier shall discharge steam at 212°F, atmospheric pressure. It shall be capable of operating with water in the range of 200 to 1500 microm-hos. The steam shall be introduced into the air stream after the chilled water coil by a calibrated discharge tube, designed to equally distribute the steam to the air stream without condensation. The humidifier shall be provided with a manual adjustable capacity control.

Reheat / Heat

A factory mounted and wired low-watt density, plated fin-tubular design electric resistance heater shall be in-cluded to provide automatic sensible re-heating as required during the dehumidification cycle and automatic heating mode. Electric heaters shall be provided with miniature thermal/magnetic circuit breakers, which shall protect each ungrounded conductor. Also included will be one automatic reset and one manual reset over-tem-perature safety device (pilot duty)

Dehumidification CycleThe system shall provide a dehu-midification control mode.

Top Discharge Plenum Box(Upflow Units Only)

A 2- or 3-way plenum discharge box shall be provided.The plenum box shall include double-deflecting, adjustable grilles.

3-Way Chilled Water Control Valve

A 3-way fully modulating valve shall be factory piped and wired. The 3-way chilled water modulating valve

shall automatically meter the flow of chilled water to the cooling coil as needed for cooling load control, the remaining flow shall bypass the cooling coil. A proportional signal (0-10 VDC) is provided to the valve by the microprocessor controller. The pressure rating of the valve is 600 psi. Manual override capabilities shall be standard on the actuator drive.

Manual Control Override Switch

A front panel mounted keyed switch shall allow full fan operation and 100% chilled water valve flow once engaged in the unlikely event of a controller failure.

Automatic Dual Power Transfer Switch

Two individual main power input dis-connect switches shall be provided, one for each incoming power source. In the event the primary power fails or a phase loss/imbalance occurs, the automatic transfer switch immedi-ately transfers power to the second-ary power source. Once the primary power has been restored, the transfer switch automatically shifts the power load back to the primary power. The transfer time from one source to the other is user adjustable to allow stag-ing or sequence restart of load.

In addition to the automatic transfer switch function, the local controller display shall indicate which power source has failed. This indication is a visual depiction that allows the user to determine the status of the input source. This status can also be conveyed thru the BMS serial com-munication link.

Compact CW systems include the C6000 Microprocessor Controller, Electrode Canister Steam Humidi-fier and Dehumidification Mode with Electric Reheat/Heat for total temperature and humidity control, as a standard.

However, these standard features can be deleted and/or substituted with alternate features to allow you the flexibility to select the configuration best suited for your application.

EXAMPLES - Electrical Data Calculation

Example 1:Suppose an application calls for a nominal 10 Ton Compact-Line CW model CCD-300-CW with the following features: - 208/3/60 Main Power Supply - Electric Reheat/Heat, (Standard) - Steam Humidifier, (Standard)Solution:From Electrical Data table page 4-5 for model CCD-300-CW incorporating COOLING with ELECTRIC REHEAT/HEAT and HUMIDIFIER: CCD-300-CW @ 208/3/60 with above options: FLA (OEM Rated) = 59.1 MCA = 73.9 MFS = 80

Example 2:Suppose an application calls for a nominal 30 Ton Compact-Line CW model CCD-900-CW system with the following features: - 460/3/60 Main Power Supply - Electric Reheat, (Standard) - No HumidifierSolution:From Electrical Data table page 4-5 for model CCD-900-CW incorpo-rating COOLING Only with Electric Reheat: CCD-900-CW @ 460/3/60 with above options:

FLA (OEM Rated) = 41.2 MCA = 51.5 MFS = 60
