Selector Exchange Interlock
Product Model: H-SEiL
ENEX i-LOCK Series H-SEiL is the heavy industry selector exchange Mechanical Trapped Key Safety Interlock product range.
It is suitable for a wide range of applications such as complex high voltage switching systems, HIPPS system change over systems, process system change over and maintenance procedure switching systems.
The H-SEiL ‘Patented’ lock portions and keys allow for any combination of key sequence procedural systems.
The basic principle of this safety equipment is to safely control the switch over between two different process systems by utilising a key sequence principle.
Each lock portion and rotary key is uniquely coded to allow a truly safe operating sequence procedure.
H-SEiL product range can be supplied with on/off switches and proximity limit sensors to confirm:
- Key entry rotation or key removal rotation
- System switch over positioning
Safety System Applications that are enhanced when the H-SEiL product range is installed are:
- Process Switch Over Systems
