If a safe shutdown of the gas supply for brittle fracture monitoring is required, many customers rely on a low temperature shutdown from LT GASETECHNIK.

In special applications, a safe gas supply with a minimum temperature is required. The low-temperature switch-off is supplemented by a flow heater. This controls the medium to an adjustable temperature and thus ensures the safe supply of media with a minimum temperature.

If this additional safety level is also exceeded, the shutdown is carried out by a shaft-driven cryo shut-off valve. A pre-alarm to enable the customer to react early without switching-off is possible.

The design is based on customer specifications, for example:

Flow heater

• Performance 1.6 KW
• Trhoughput N₂ at 125 kg/h
  Adaptation of the heater to the desired throughput and ΔT
• Inlet temperature -30 °C
• Outlet temperature 5 °C

Control system

• Small PLC control with individual programming
• 4″ Touch color display
• Interface: CAN, Ethernet, RS-232, RS-485, USB, REMOTE E/A
• Thyristor controller for the heating cartridge of the flow heater

Mounting

• Shaft-driven cryo shut-off valve, designed for: -196 ° C / PN 40
• Resistance thermometer incl. Transmitter
• Light-horn
• Frame with galvanized steel profile rails and roof
• Traverse height adjustable for individual adaptation to on-site conditions
• On site, only the supply voltage, control medium and pipes need to be connected

Equipment variants

LT low temperature switch-offs are always designed according to customer specifications and equipped accordingly. The following equipment variations are possible:

• Design in SIL 1 or SIL 2
• Delivery incl. Cryo switch-off valve
• GSM modem for SMS– or mail dispatch
• Network connection according to Industry 4.0 requirements
