Product Description

Gas Preheaters

LRX 500,

For preheating of inert and non-corrosive gases, not for flammable gases or oxygen, inlet pressure max. 230 bar/ 3300 psi

SPECIAL FEATURES

  • High performance for gases and liquids
  • Electric protector IP66 (EN 60947)

Description

The LRX is a high performance preheating appliance for the central gas supply. It is delivered fully mounted with 1m cable (3×1.5 mm2) and safety power supply plug. The resistor unit is replaceable (in the factory only) with a protective casing of stainless steel.

Application

The preheating appliance LRX is used to raise the temperature from gases before their entrance in the pressure regulator and to avoid freezing of valves or following equipment. It can also be used to vaporise liquid gases and in particular for use with carbon dioxide, argon and nitrous oxide, as well as with gas mixtures out of non-flammable gases which contain CO2 or argon.

CONTACT GAUGES KI 50 - NPT 1/4"

  • Contact gauge with inductive contact (KI),
  • For visual and acoustic warning of low gas supply pressure and to monitor the cylinder pressures
  • For inert, combustible, oxidizing and corrosive gases and gas mixtures, nominal pressure maximum 230 bar.

SPECIAL FEATURES

  • Construction conforms to safety regulations EN837-01
  • Switching point is freely adjustable in marked area (45°)
  • Pressure display at location and signal transmission for recording measured data
  • Ex-protection is possible in conjunction with corresponding signal box

DESCRIPTION

These pressure measuring instruments have a robust chrome nickel steel/cooper-zinc-alloy housing in accordance with DIN 16063. When the gas cylinder is empty and by sinking cylinder pressure an inductive contact switch is activated. The switch point, i.e. the pressure level at which the signal should be triggered is freely adjustable within a sector of 45° (at 315 bar type e.g. 38 bar). To set the switch point the pressure level marking is simply adjusted to the desired switch point.

APPLICATION

Panel and manifolds can be fitted out with contact gauges as an optional. Contact gauges combine the advantages of a local display with the demand for an electric signal transmission. This allows for - in conjunction with special signal boxes - the optical and acoustic warning signal by low gas supply pressure or the monitoring of the line pressure with freely adjustable threshold.

NOTICE ABOUT ELECTRICAL CONNECTIONS

The polarity must be taken into consideration when connecting as the inductive contact is an active electronic component, The KI 50 can only be operated with a special amplifier.
