Arnold Group, The most advanced Turbine Insulation combined with high performance heating System.

ARNOLD has been comparing traditional Insulation provided by the OEMs and compared it in terms of fitness, tightness, efficiency and maintainability with the ARNOLD Insulation system. The focus of the presentation was on explaining the advantages of a Single Layer Insulation system in terms of operation and maintenance as well as durability and cost efficiency. Most of the Units in the field are still using the original standard multilayer insulation with poor performance due to many removal and reinstalls which are causing ongoing degradation and related repair effort and cost.

The Solution ARNOLD provides will cut cost during maintenance and increase the performance during operation.

DEKOMTE manufactures fabric and metallic expansion joints and bellows, designed and constructed to compensate for changes in length due to shifting temperatures in duct work. Axial, lateral and angular movements are compensated for.

DEKOMTE expansion joints are available in any geometric shape (round, square, oval, multi-sided) and in any size.

Dekomte explained technologies, selection and criterias for proper expansion joint selection and maintenance:

• Expansion joints for SGT500, 600, 700 and 800 as OEM supplier.
• New design available for SGT800 with usage of standardized parts, less turbulence of the flow and easier installation.

Minimax Fire Solutions International GmbH - Office Bremen, Competence Center Power, Oil & Gas is specialized in firefighting systems for gas and steam turbines, compressors, generators, motors and engines. They have successfully executed orders in the Oil & Gas market and also provide fire and gas detection systems according to SIL 1, 2 & 3 (Safety Integrity Level).

Minimax fire detection and protection systems are installed in more than 500 Siemens Gas Turbines worldwide. Majority of these turbines are of type SGT800 and its predecessor model GTX100. Since these turbines are already in operation for years, Minimax talked about some very important aspects related to their systems as:

1.    Service:
Why Minimax services?

• Productivity:     Minimizing unplanned turbine downtime
• Safety:        Ensure the overall and personnel safety at your plant
• Laws:        Meeting requirements by the authorities & insurances
• Minimax offers their site services worldwide
• Minimax is highly recommending preventive maintenance of your systems to avoid down times!

2.    Modernization/Upgrades:

• Minimax fire detection and control panel series FMZ4100 has been discontinued
• on 19/04/2013, Germany has implemented new EU directives (RoHS-II 2011) into national legislation as a result of which, as of 22/07/2017!, Minimax is no longer offering any spare parts to the market for control panel series FMZ4100
• Until 2020, the next possible solution was Minimax FMZ5000 fire control panels which is a successor model of FMZ4100
• In the second quarter of 2020, Minimax launched their “CLUNID FMZ6000” fire control panel. It is already successfully installed and operating trouble free at various sites in the world
• There are few detectors and signaling devices which are also discontinued and shall be replaced with their successor models

FMZ 4100 HAS TO BE EXCHANGED AS SOON AS POSSIBLE!!!

3.    Spare Parts:
Minimax is highly recommending,

• to have a set of recommended spare parts at site, this will not only ensure minimum downtime of the turbines/systems in the event of malfunction or fire but, also help the service and maintenance activities at site
• that the end users take notice of the required exchange intervals of various detectors and devices.
