Compressors

Oil & Gas

Our couplings and coolers are used in screw and piston compressors as well as special-purpose compressors. We offer the right components for both electric and I. C. engine-driven fans and compressors.

The right coupling for every need

We offer a broad and comprehensive portfolio of maintenance-free and service-friendly couplings of various designs with different properties.

Shaft, jaw, laminae and flange couplings,
torsionally rigid, torsionally flexible or highly torsionally flexible as well as
hermetically sealed magnetic couplings for contactless torque transmission.

The scope of delivery of each coupling includes torsional vibration calculations and technical documentation such as drawings, assembly instructions and quality documents.

Certifications and classification societies

KTR offers a wide range of couplings that have been assessed and certified in accordance with the European ATEX product directive 2014/34/EU. The portfolio also includes couplings that comply with API directives 610, 671 and 685. Besides, KTR is one of Petroleum Development Oman’s certified partners and one of Saudi Aramco’s preferred suppliers.

Our drive components have also been used worldwide in marine propulsion systems for many years. We have received approvals from the classification societies Germanischer Lloyd (GL), Det Norske Veritas (DNV), Bureau Veritas, American Bureau of Shipping (ABS), Class NK and GOST R/GOST TR.

Tailor-made compressor cooling

Cooling systems for cooling air, oil and water glycol

We develop and manufacture tailor-made combined coolers for all common compressor technologies. Our compressed air coolers are designed for a maximum operating pressure of 45 bars.

Upon request, we also design the coolers in accordance with the Pressure Equipment Directive, category II. The scope of delivery comprises the full technical documentation, EU Declaration of Conformity and the CE marking with the identification number of the notified body involved.

In-house cooler production

By manufacturing the cooling systems at its own cooler plant, KTR covers the entire value-added chain. The heat exchangers being heart of the combined cooling system are also manufactured there.

While production is highly automated, even small batches are manufactured in the assembly area to the highest quality standards. The plant holds welding certificates in accordance with ISO 3834-2 and EN 15085-2 as well as a quality management system certified acc. to DIN EN ISO 9001.

At the R&D centre: Test bench for multi-circuit coolers

At its headquarters in Rheine, KTR has a fully automated test bench for performance testing of multi-circuit coolers. A defined flow rate of coolant, compressed air or hydraulic oil is supplied to the cooler to be tested. The operating parameters of the media to be cooled such as pressure and temperature are set and monitored. At the same time, cooling air is directed toward the test specimen from the outside – with the flow rate, temperature, and pressure again being defined. The cooling capacity can be determined from the temperature drop in the test specimens. External and internal pressure losses are also measured.

With these features, the new test bench enables the optimization of customized multi-circuit coolers to meet specific requirements and performance profiles.
