The S80 series is reportedly different from any screw compressor design. By placing the rotors above each other, it has been possible to place the discharge connection at the side and make the compressor lower. Additionally, the mass of the compressor housing is evenly distributed around the rotors, and as a result, the compressor has a compact design, and reduces vibrations and sound level significantly compared to earlier models. The new models have fewer connections than previous models; instead most oil and gas pas- sages are integrated as channels within the housing, reportedly increasing operating reli- ability and minimizing risk of oil and refrigerant leakages. The economizer port in the S80 series is mov- able and integrated with the capacity slide valve, enabling the compressor to maintain an optimal intermediate pressure within a wide operating range. The compressor can reportedly be used optimally at varying loads, providing higher efficiency even at reduced capacities. All five models have been provided with two indepen- dent systems for regulating volume ratio and capacity, reportedly improving part load effi- ciency. Slide valve Stal-Maxi S80, a different design of screw compressor with the rotors on top of each other. The slide valve is in separate cylinder and the compressor incorporates an integrated suction strainer. The ratio between the length and diameter of the rotors is individually optimized for each model, reportedly giving increased overall effi- ciency and lower operating costs. Another detail distinguishing the S80 series from its predeces- sors is the introduction of an integrated suction strainer. At the same time, the strainer area has been increased to reduce the pressure drop and increase efficiency. A designed advantage of the new series is optimal performance at reduced capacities. De- pending on operating conditions, choice of refrig- erant and load profile, the new compressors can reduce operating costs by as much as 10 percent. A completely new digital controller is de- signed to simplify operations and facilitate com- munication with other process control and su- pervision systems. Up to eight compressors may be connected for sequential operation. ABB Stal envisions a large potential market for the new line, including reefer operators.

Hollywood Casino Corp. Purchases Mississippi Casino Project Hollywood Casino Corp., a Texas-based gam- ing and lodging company, announced its pur- chase of a dockside gaming facility which is currently under construction in Tunica County, Miss. The project, which will be renamed Hollywood Casino-Tunica, is slated for a June 1994 opening. Hollywood Casino Corp. purchased the project from Summit Casinos International, Inc. The total purchase price of $15 million in- cludes all assets currently in place, as well as all rights of Summit Casinos International, Inc. in the project. The total cost of the project is estimated to be $70 million. "When the prospect of purchasing a facility which was already under construction arose in an area with 4.1 million people within a 150-mile radius, we saw an excellent opportunity for a quality gaming operation," said Jack Pratt, chairman and CEO of Hollywood Casino Corpo- ration. Maritime Progress Now Exclusive Distributor For TVP2000 Voltage Protectors Maritime Progress is now the exclusive dis- tributor to the marine industry for Unity Tran- sient Voltage Protectors (TVP2000). The TVP 2000 reportedly has a long and successful history of protecting sensitive electronic equipment against damage and/or disruptions arising from transient voltage both on land and in marine applications. Reportedly the TVP2000 is easily retrofitted to motors, generators and distribu- tion panels, and will effectively eliminate voltage disturbances created by lightning, power line switching and cycling of electrical equipment.
