n Liquid Leak Detection/Location Systems for piping, raised floors, semiconductor tools, containment piping, fuel systems and other applications
Company Profile n PermAlert is part of Perma-Pipe the largest prefabricated – preinsulated pipe manufacturer in the US n PAL-AT Leak Detection was introduced in 1988 and was the reason for founding PermAlert ESP n Sales Volume of the parent corporation (MFRI) is about US $178 million with over 500 employees worldwide
Art Giesler n Mechanical Engineer from UMR n Worked for York Air Conditioning n MBA from TCU n Hydro-Air, Inc. a manufacturers rep n PermAlert ESP n Projects: Social Security, VISA, IBM, Intel, AMD, HP, Exodus, Digital Island, US West, Nuclear Power Plants, DOE
PAL-AT Cable Systems and LiquidWatch Probe Systems PAL-AT Cable Systems and LiquidWatch Probe Systems n PAL-AT uses coaxial cables and probes to monitor for liquid leakage. The system can detect and locate leaks, breaks and shorts on the sensor cable as well as probe activations. n LiquidWatch is a probe monitoring system and can monitor up to 64 probes from a single panel. The probes are monitored for activation, breaks and shorts.
Time Domain Reflectometry PAL-AT n TDR is a cable measuring technology related to sonar and radar. By sending energy pulses down the center conductor of a coaxial cable and measuring the reflected energy to the outer braid a map can be stored of the cable and monitored for change. When change occurs the type of alarm and its location is displayed on the panel.
PAL-AT Panels n AT20C - Monitoring up to 2,000 (600 m) on a single cable n AT50C - Monitoring up to 5,000 (1500 m) equivalent length on a single cable n AT20K - Monitoring up to 7,500 (2500 m) equivalent length per cable with a maximum of two cables n AT40K - Monitoring up to 5,000 (1500m) equivalent length per cable with a maximum of eight cables n AT80K - Monitoring up to 7,500 (2500 m) equivalent length per cable with a maximum of eight cables
Types of Cable PAL-AT n AGW Gold Sensor cable for use in containment piping, trenches, trays and subfloors and subfloors n AGT Gold Sensor cable for use in subfloors and trays. More sensitive than AGW n TFH Sensor cable for detecting hydrocarbons and solvents while ignoring water TFH n TFH
Types of Probes PAL-AT and LiquidWatch n PHL/PWS Solid state probes for hydrocarbon and conductive liquids n PSTV/PTHL/PFS Float switches for high/low level n PT10 (PAL-AT) Probe integrators and PA-10 (LiquidWatch) Probe Adaptors for dry contacts
LiquidWatch n LiquidWatch has two basic panels. The LW64 is for use in normal classified probe locations while the LW64IS provides a UL Listed System for monitoring in Class 1, Division 1 Groups C & D locations. The basic panel monitors up to eight probes with modules being added for additional probe requirements.
Applications n Raised Floors - Data Centers, ISPs, Clean Rooms Telecommunication, Semiconductor, Office Bldgs Pharmaceutical n Piping - Containment piping, single wall piping, hydrocarbon piping, waste drains n Trenches and Trays - Under wet benches, piping and equipment n Generators, Electrical Switch Gear and Transformers for hydrocarbon leakage or water seepage n What ever needs liquid leakage detection that a probe or sensor cable can be used
Palcom Software PAL-AT and LiquidWatch n Palcom allows remote control of up to 254 panels with the ability to review TDR traces, review the history of each unit and to pull down a Cad drawing for each system for location of leaks, breaks, shorts or probe activation's.
