Exceptional Control

User-Friendly Touch Screen Panel

Every Magnitude chiller is provided with the user-

friendly operator interface touch screen panel

mounted on the moveable positioning arm for easy

viewing and operation.

View chiller status, clear faults and change

parameters by merely touching the screen.

For added convenience, the unit operating and

maintenance manual is viewable on the screen and

can be downloaded and printed via the USB port

located in the control panel.

Flexible BAS Interface Modules

Every Magnitude chiller with MicroTech®II

controls and the Open Choices™ feature can be

provided with L

ONWORKS, BACnet, or

Modbus communications modules for an easy, low

cost connection to the building automation system of

your choice. Expensive and complex interface

gateways are not required.

Modules can also be easily retrofitted after

installation.

Variable Frequency Drives

Compressor unloading and subsequent chiller

capacity reduction is accomplished by a

compressor-mounted variable frequency drive. It

operates in conjunction with the inlet guide vanes.

The VFDs are a key factor in providing the

tremendous energy savings at part load operation.

Seismic Certification Option

WMC units are OSHPD Pre-Approved and so

labeled. (California only).

WMC units are certified to IBC 2009 and so

labeled.

Low Operating Costs

Shrink Your Utility Costs with Ultra

Efficient Part-Load Performance

The Magnitude chiller Integrated

Part Load Value (IPLV) is as low

as 0.328 kW/Ton. Compare this

with most screw compressor

chillers - approximately 0.575

kW/Ton. There is a potential for

up to 40% energy savings at part

load compared to other chillers.

Virtually Eliminate Maintenance Costs

Oil samples, oil change-outs,

oil system maintenance, oil

filter changes are eliminated.

The bearing system, shafting

and impellers are shown

here.

Environmental Responsibility

Long Term Refrigerant Solution

The Magnitude chiller uses R-134a refrigerant,

which does not have a phase-out date and does not

attack the ozone layer.

Ultra Quiet Sound Levels

The Magnitude chiller is the quietest chiller in the

industry for its size range. It is perfect for sound

sensitive applications. See published ratings on page

17.

The best way

to appreciate how quiet these units are

is to hear one operate. It is important to compare the

sound data in this catalog to other offerings.

Remember that a sound pressure difference of only

two to three dBA is a very noticeable difference. A

number of owners have asked for a large indicating

light on the unit so they can tell when it’s on!
