Our products and services in the following areas have many practical applications: steam generation, control, fluid systems, energy saving, environmental protection and safe position control system. 

 The Gestra-trap and trap testing 

 The GESTRA the trap including thermal power, thermal static and float three series. Widely used in the superheated steam to saturated steam from high pressure to low pressure differential displacement, from small to large displacement of a variety of complex industrial conditions. Trap detection equipment can detect the performance of the trap, to prevent live steam loss. Including the BK Series TK pilot series UNA float series of thermal power type DK, ZK and GK series, etc.. 

 Bi-metal trap-BK series

 Built-in check valve 
 Suitable for superheated steam applications 
 Internal material for stainless steel 
 Can be installed in any position 
 Typical models: BK212 BK28, the ASTM B28, BK29, BK45, BK35, BK45, etc. 

 -MK series of ultra-sensitive reaction characteristics of the membrane box trap built-in check valve inside the stainless steel can be installed in any position 
 Typical Model: MK45-1 MK45-2, MK35/31, MK45 A-1, MK36/51 etc. 

 The UNA float series - without the environmental impact of back pressure and condensate temperature, does not appear to the accumulation of condensate in the state of extreme load and pressure fluctuations. 

 Typical Model: UNA13, UNA15 UNA23, UNA25 UNA26, UNA27, UNA39 etc. 

 Trap-AK45 applicable to special occasions, UBK46 SMK22, MK20, TK23, TK24

 GESTRA oil detector / alarm ORGS 11-2 

 Is based on the principle of conductivity measurement. The electronic control unit of the ORGS 11-2 alarm integration module of a terminal shell, used to control all functions, thus eliminating the need to use an external switching device to a control and alarm devices should be added downstream of the ORGS 11-2 protection needs of the cooling device to prevent possible leakage. ORGS 11-2 has two channels, the real fault protection. 
 With one level electrode level limiter for Flanges PN 320 

 The GESTRA-level electrode NRG 111-11 
 For the lowest level (low level alarm) in the detection of steam boilers. The electrode is based on conductivity measurement principle, it is issued under the conductivity of the water level signal. 

 Features and Benefits 
 Low level limiter with periodic self-test (SMART) feature 
 Pressure and temperature to the value of the superheated steam conditions 
 Can be used in power plant boiler 

 Capacitance Level Electrode NRG 211 
 Indicates the high level) and the GESTRA NRS 2-4 types of liquid level switch (NRS 2-5 Type Level Switch (indicating a low level) used in combination, suitable for any high-pressure high-temperature conditions (up to PN 320,550% B0C ). Can be installed into the drainage system of the traditional power plants and high-pressure steam boiler. 

 Features and Benefits 

 Do not have to use any moving parts 
 Ceramic tube 
 Maximum pressure under the liquid level detection 
 Reliable monitoring of the drainage system of the turbine
