The TESCOM Compact Panel is a central gas supply unit for the pressure control of analytical gases in laboratory facilities. Depending on the requirements, these units switch over to a spare cylinder in order to enable a continuous gas supply. The use of contact gauges allows the monitoring of empty gas cylinders.

Applications• Central gas supply for the distribution of gases in

laboratory applications

• Supply of gases for laser cutting applications

• Various other processes requiring continuos gas supply

Features and Benefits• Few connections and minimized internal volume

due to the integration of valves and pressure regulator in one body

• Suitable for ECD (Electron Capture Detector) applications

• Short purging time when changing cylinders

• Purging with process or inert gas

• Easy and quick to maintain - a P & ID is located on front of the panel

• Stainless Steel mounting plate for corrosive environments

• Very compact design (fits into most gas cabinets)

• All versions contain a filter element in the inlet

System Components for Compact PanelsManifolds/Changeover Regulators DCATLABO12166XEN2

The annunciator system is used in combination with a cylinder station in order to avoid a complete discharge of the cylinder which would cause an interruption of the process. The annunciator system consists of a signal box, the pressure switches or contact gauges and the electrical wiring. For Explosion Proof environments a Switch Amplifier Box (Ex-Modul) must be added. The annunciation consists of an integrated horn, lights or an additional external indicator.

Application

• Easy continuous monitoring of gas storage

Features and Benefits

• One annunciator system monitors up to 10 contact pressure gauges

• Acoustical and optical signals

• Error messages can be forwarded to external systems using potential-free relay contacts

Emergency Switch-Off System(Solenoid Valve, Control Box and Emergency Switch)

The emergency switch-off system acts in case of emergency or other hazardous events as an electrical operated quick shut-off for main pipe systems, floor pipe systems or room pipe systems. All gas supplies will be stopped at the feeding points already. In combination with a control box and a gas warning system the emergency switch-off system is an important part of the central gas supply system.

Applications

• Solenoid valves control the gas stream after the compact panels

• The Solenoid Valve Control Box is needed to control solenoid valves in case an emergency shut-down is necessary

• Safety device according TRG 280


• Easy to install

• Reliable design

• Long-life system

High Pressure Pigtail Assemblies

The pigtail assembly consists of a metal cylinder lead, that is either a looped tube or a flexible hose with a gas specific connector at one end and a compression fitting at the other end. It is used to interconnect the Compact Panel manifold to a storage gas cylinder or a cylinder bundle. Loop construction permits spacing adjustments between cylinders. TESCOM Pigtails are made of Stainless Steel and available for various national gas cylinder valves. TESCOM Pigtails are designed for high pressure applications up to a nominal pressure of 4350 psig / 300 bar. All TESCOM Pigtails are manufactured with a compression fitting 6 mm.
