Our experts in cooperation and partnership with other international engineering teams are at your disposal for the development, production and repair of blades, vanes and other components of gas turbines from the following list:

Siemens: V94.2 (SGT5-2000E), V94.3A (SGT5-4000F), SGT-600, SGT-700, SGT-800
GE (General Electric): LM2500, LM6000, 6FA (6F.03), MS9001FA, MS9001FB
Alstom: GT13E2
MHI (Mitsubishi Heavy Industries): M701F4

ENCE GmbH is in a position to arrange manufacturing of moving blades and other components of hot section using reverse engineering for all the above gas turbine models.

Installation of an integrated system for gas turbine status monitoring:

This software package is an exclusive product, having no in-kind counterparts, even from GE, Siemens and Alstom (the software package is designated for downtime reduction and on-line monitoring of gas turbine operation in real time with visualization of DLE engine parameters). This software also supports environmental operation of gas turbines with efficient reduction in NOx, CO and CO2 emissions. This system has been already used at several plants in Europe and has a proven record of operation.

Quality assurance and ENCE GmbH warranty period:

The key objective of ENCE GmbH is meeting the requests of all customer (company) through continuous improvement of quality control systems which are fully compliant with ISO 9001-2008 quality management standard.

Our products are kept in line with quality assurance guidelines. ENCE GmbH is capable to supply moving blades and other hot section parts with the warranty period equal to or exceeding that of OEMs for the proposed components from our partners - market leaders in this area. These components have a global proven record of operation at many facilities.

All the documents required for inspection and checking of cast components for the compliance of moulding, manufacturing process and coating will be provided with each consignment.
