Steam traps are much more than just drainage fittings – they are indispensable functional elements in modern steam, energy and process systems. In SKID systems, they are responsible for the safe, efficient and load-dependent drainage of condensate, thus ensuring trouble-free operation, constant energy efficiency and the protection of sensitive components.
Especially in compact, modular system packages, steam traps must work reliably, handle different pressures and temperatures and be flexibly integrated into any installation situation.
Our steam traps – including thermal versions with diaphragm regulators such as the MK45 from GESTRA – are used as integral system components in SKID and process plant construction and ensure maximum operational reliability even under demanding conditions.
EN 1092-1, ASME B16.5, Pressure Equipment Directive, ATEX-compliant.
