PBS Velka Bites Focuses On Higher

Efficiency Turbo-chargers

PBS Velka Bites AS, of the Czech Republic, has manufactured turbochargers for diesel engines for more than 40 years. PBS recent- ly finished the first stage of development of its new PTR series, which reportedly has a higher pressure ratio than four, and increased efficiency parameters. The first sets have been tested, with good results on diesel and gas engines reported. The next step of development is to increase the maxi- mum compression ratio, while keeping high reliability in mind.

The new PTR turbocharger series report- edly features considerable improvements, including a radial centrifugal compressor with back-swept blades and a radial-axial turbine.

The turbine and compressor wheels are arranged on overhanging ends of the shaft.

Plain bearings located between the wheels have been used.

Turbine and compressor casings are sin- gle, one-wall casings. The bearing casing is partially water cooled.

Gestra To Introduce

New Electronic Temp Control

A wide range of valves and indus- trial electronic equipment for ener- gy management on ships and in the offshore area is scheduled to be and safer. On the TRR 5-1, the temperature controller and control valve together form a single unit already wired for installation. The

TRR 5-1 is programmed by means of the vibration-insensitive pro- gramming switches built into the unit.

With this constellation, tempera- ture data can be fed directly to the control room for process monitor- ing.

ABB Turbochargers To Set

Up In Engine Builders Hall

ABB Turbochargers will have its own booth at SMM. Although it is part of the ABB Group and is the largest ABB organization in the marine sector, it is active in differ- ent markets, and the company saw it as a logical strategy to move to the engine builders' pavilion.
