SIERRA™

The Sierra™ system is ideal for a variety of commercial applications such as convenience stores, restaurants and
fast food outlets. Sierra’s substantial savings in operating costs make it the right choice for commercial warehouses.
Sierra™ offers a winning combination of energy savings, lower installed costs, and increased reliability. Models are
available from 1/2 to 30 horsepower in low, medium, and high temperature ranges. Systems are available with
HCFC R-22 and environmentally friendly HFC R-404A. All condensing units are intended for outdoor installation.

All Sierra™ systems are shipped with piping accessories factory installed. This saves on installation time, and takes
the guess work out of selecting components. Sierra™ systems come complete with the following features and
accessories:

STANDARD FEATURES

Semi-hermetic, hermetic, discus, or Scroll compressors Electric defrost provisions on low temp evaporator(s)
Oil pressure control where applicable Specially sized balanced port expansion valve(s) (mounted)
High and low pressure controls Liquid solenoid valve(s) (mounted)
Crankcase heater Room thermostat
Low profile galvanized steel housing Liquid line filter-drier (mounted)
Copper tube, Aluminum fin condenser Sightglass with moisture indicator (mounted)
Vibrasorbers (semi-hermetic models only) Suction line filter (mounted)
Large electrical control panel Russ Saver™ floating head pressure control
Compressor contractor or start kit Liquid refrigerant subcooling circuit
Liquid line charging valve Fan cycle control (dual fan condensing unit only)

SIERRA™

What is Sierra™?

Sierra™ is a unique concept in commercial refrigeration that incorporates a number of features which enhance

performance, provide energy savings over conventional systems and increase of reliability, thus saving you
money.

The heart of the Sierra™ system is a design that eliminates the need for a refrigerant receiver by providing built-in
storage capacity in the condenser section of the condensing unit. This small charge in the unit has opened the
door for adding new features that are not possible with traditional refrigeration systems.

INCREASED PERFORMANCE

Sierra™ maintains traditional refrigerant storage capacity while increasing the condenser capacity. It actually

gives the same size condenser up to 20% more capability by providing a potential 50% increase in condenser
surface. This feature reduces condensing temperatures when compared to conventional systems. In addition,

Sierra™

increases compressor life

by reducing the operating head pressure.

INCREASED ENERGY SAVINGS

The increase in the condenser size and lower operating head pressure provide an initial energy savings of up to
10%. In order to take full advantage of Sierra’s large condenser, a subcooling section and Russ Saver™ floating
head pressure features are incorporated to save even more energy.

The Russ Saver™ feature provides up to 30% in additional energy savings during low ambient conditions.
Additionally, it also supplies subcooled liquid refrigerant to the expansion valve to maintain optimum valve
performance. Thus, Sierra™ can offer energy savings of up to 40% over conventional refrigeration systems. (See
page 5 for calculation of Projected Monthly Savings.)

LESS REFRIGERANT

Sierra™ requires up to 20% less refrigerant to operate while maintaining continuous peak performance. This is

accomplished several ways. 1) by dispensing with the conventional receiver, a minimum refrigerant charge is not
required to maintain a liquid seal in the receiver. 2) by assuring that only liquid refrigerant is entering into the
subcooler section of the condenser because ambient air is flowing over the receiver section of the condenser coil.

3) by eliminating the useless overcharging of the system with refrigerant, often a result of varied industry
practices. In typical systems, the receiver, its outlet valve and piping will create bubbles in the sightglass due to
pressure drop they create. This in turn results in the addition of extra refrigerant by the installer in an attempt to
clear the sightglass. By eliminating the receiver and its piping components, the clearing of the sightglass occurs
much faster. Sierra’s critically positioned sightglass signals when the ideal charge has been attained, thus saving
refrigerant. With today’s refrigerant costs, Sierra™ makes even more sense.

ENERGY SAVINGS CALCULATIONS

To estimate your average monthly savings:

1) Select a SIERRA™ system that meets your refrigeration requirements.

2) Determine the Average Annual Outdoor Air Temperature from the table below.

3) Using the Projected Monthly Savings graph, locate the system nominal horsepower at the bottom of the
graph (the nominal system horsepower can be derived from the model number nomenclature).

4) Go straight up to the appropriate Average Annual Outdoor Air Temperature curve, and then go horizontally
to the left to determine your Estimated Monthly Average Savings.

5) To calculate your Estimated Monthly Saving for an energy cost other than $0.10 KWH, divide the Estimated
Monthly Savings by 0.10 and multiply by your local electric utility rate.

6) To determine your Estimated Yearly Savings, multiple the Estimated Monthly Savings number by 12.
