Emerson Climate Technologies has revolutionized the industry with the introduction of its scroll technology, which was launched in 1987. In 2012, Emerson produced its 100 millionth scroll - a significant achievement and further demonstrating Emerson’s position as a world leader in the development and application of scroll technology.
Digital Scroll Advantage for Rack Systems Digital scroll compressors having modulation capabilities from 10%–100% naturally fit refrigeration rack systems. Rack systems need to fulfill varying evaporator load requirements due to changing case loads, not to mention variations due to cases undergoing routine defrost. This can be attained by complementing fixed-speed compressor racks with a digital scroll of the same capacity.

Scroll Rack Application Guidelines 1. Introduction Parallel operation is when several compressors are operating on one common refrigeration system. These installations require a special design to achieve a maximum possible operating capacity and reliability. Only the system design engineer can make the decision which configuration of installation is to be used in view of the particular requirements.

It will be necessary to add oil to the system and the Emerson Climate Technologies approved lubricants are Emkarate RL 32-3MAF and Mobil EAL Arctic 22 CC.
Page 39
Notes are given below on some possible methods, but because of wide variations in system design and operating conditions, these methods cannot be given general approval by Emerson Climate Technologies. The user has to verify operation in each system type.

4.4 Oil equalization line The oil equalization line between the two or three compressors must be at least 7/8” (22 mm) with a minimum inner diameter of 19 mm. On no account must the internal diameter of any fitting in this line be less than 19 mm. It is strongly recommended that a sight glass be fitted using adaptors.

6. Tubing and mounting considerations 6.1 Starting pulse The standard mount for the scroll compressor is a soft rubber mount. It is designed to transmit the lowest possible disturbance to the mounting frame. Because of the flexibility of this mount, it is essential that tubing to each compressor be designed to accommodate the movement which will occur, particularly upon start-up.

Design points 7.1 Suction line header The suction lines running from the evaporators to the compressors should be led to a common main suction header in which the suction pressures can equalize.
Digital Compressor Rack Controller-XC645CX General Description The XC645CX is designed to manage both compressors and fans in a condensing system such as a pack. The compressors can be digital scroll, simple, multistage. Control is by means of a neutral zone or proportional band and is based on the pressure or temperature sensed in the LP suction (compressors) and HP (condenser) circuits.

Mounting and Installation The instruments are suitable only for internal use. Instruments shall be mounted on panel, in a 29x71 mm hole, and fixed using the special brackets supplied. The ambient operating temperature range is between -10–60°C. Avoid locations subject to heavy vibration, corrosive gases or excessive dirt. The same applies to the probes. Ensure ventilation around the instrument.
• How to set the range of the pressure probes If an instrument with the following part number is used: XC645CX – xxxxF, it is pre-set to work with pressure probe with the following range: Probe 1: -0.5 –11.0 bar (relative pressure); Probe 2: 0–30.0 bar (relative pressure) If the probes you’re using have a different range act as in the following: To set the pressure range of the Probe 1 (suction probe) use the parameter:...
