Standard & Optional Features

HDH Outdoor Discus® Condensing Units, Horizontal Air Discharge

Leak Resistant Design

The HDH Outdoor Discus® Condensing Unit features a new leak resistant design which includes:

• The Floating Tube

™

condenser coil design. Refrigerant carrying copper tubes do not contact any metal support tubes. Instead, the coil is constructed with expanded anchor tubes which support the coil construction and do not carry refrigerant. The coil design eliminates one of the major causes of leaks in refrigeration systems

• Limited ﬁve-year warranty against condenser tube sheet and center support leaks

• Designed for use with R-404A or R-507

• R-22 models available for all temperature applications

• Polyol Ester Oil charge on all units

• Pre-bent copper tubes minimize braze joints on internal piping

• All sweat type connections, no ﬂare joints to leak

• Fixed high pressure switch eliminates capillary tube. Adjustable low pressure control comed with braided hose

• Sentronic

™

electronic oil safety control

• Service Mate™ module to assist troubleshooting

Standard Features

• High efﬁciency Copeland Discus

compressors with

POE oil

• Spring mounted compressor with suction and discharge vibration eliminators

• Crankcase heater sleeve isolates the heater from direct contact with the oil

• Thermally protected permanently lubricated PSC condenser fan motors (all units have several motors)

• Two valve adjustable head pressure control

• Separate subcooling circuit in condenser for added capacity and vapor free liquid

• Receivers are sized for sufﬁcient pumpdown capacity with inlet and outlet service valves

• Pressure relief valve on receiver

• Sealed liquid line ﬁlter drier and sight glass

Service Mate™ diagnostic module on Beacon II™ units

•

• Electrical controls including compressor contactor and optional defrost control are located in easily accessible control box with a hinged cover

• Pumpdown switch

• Cabinet is constructed from pre-painted G90 steel

• Convenient access panels for easy servicing to internal components

Expanded (Locked) Auxiliary Tubes: These

tubes support the coil with ns and refrigerant carrying tubes. They do not carry refrigerant and are tightly tted on end supports and center supports.

Free-Floating Circuited Coil Tubes:

These tubes carry refrigerant and never touch any sheet metal (end supports and center supports).

Factory-Installed Optional Features

• Replaceable core liquid ﬁlter/drier

• Liquid line solenoid valve

• Sealed suction ﬁlter

• Replaceable core suction ﬁlter

• Suction accumulator

• Oil separator with discharge line check valve

• Air defrost timer

• Electric defrost kits, including timer, evaporative fan contractor with fusing, defrost heater contactor(s), lockout relay and terminal strip

• Fusing for heater loads

• Heated and insulated receiver with time delay relay

• Fused disconnect switch

• Condenser fan cycling

• Compressor unloading

• Demand cooling on low temperature R-22 models

• Coated condenser coils for protection against corrosion in harsh environments

• Beacon II™ Control System

• Alternative compressors (contact factory)

Now available with Beacon II

™

Beacon II™ is the next generation of Chandler’s patented, preassembled, factory installed refrigeration system featuring an integrated microcomputer-based electronic control board. The Beacon II™ system comes completely factory installed, wired and tested saving you time and money.

Beacon II™ offers:

• Complete factory installation, wiring and testing which saves time and money

• Simple ﬁeld electrical connections and 24 volt wiring between condensing and evaporator units

• Preset factory superheat allowing the system to run more efﬁciently and reducing future adjustments

• Monitors and controls box temperature, evaporator superheat, condenser fan cycling, system status and defrost from outside the box

• Monitor and make system changes remotely via modem and exclusive Beacon II™ Smart II software

• Data logging capabilities with Smart Controller

Beacon II™ Smart Controller

The Beacon II™ Smart Controller is an optional system monitoring and programming control device. It allows for adjustments to be made at the push of a button from a conveniently mounted location. The Beacon II™ Smart Controller also allows you to monitor and make changes to the refrigeration system via modem connection from anywhere in the world. The Beacon II™ has been updated to allow the user to make even more precise adjustments than the ﬁrst phase of the Beacon II™ Smart Controller. One Smart Controller can program and control up to four separate condensing units with up to four evaporators on each system. That’s more control in your hands!

™

Beacon II

Smart II Software

Beacon II™ Smart II Software makes it easy to adjust and monitor one or more refrigeration systems as well as capture minute by minute system conditions. This Windows-based software allows you to connect to the Beacon II™ Smart Controller from anywhere in the world to monitor the systems, make adjustments and log minute by minute system conditions. This data logging capability is critical in the food service industry.

™

Beacon II

Smart Defrost

Beacon II™ Smart Defrost, available only on the Beacon II™ Smart Controller, enables the Beacon II™ system to sense frost accumulation and initiate defrost only when it is necessary. Using the Beacon II™ Smart Controller, you preset defrost times. At each scheduled defrost time, Smart Defrost checks system performance to see if a defrost is necessary. If not, it simply does not defrost, waiting until the next scheduled defrost time.
