LIEBERT LIQUI-TECT® 410Point Leak Detection SensorProduct Specification Sheet

Description The Liebert Liqui-tect 410 (LT410) provides a single-point detection of leaks. The point detection sensor has two gold-plated sensing probes to prevent corrosion resistance and to provide accurate readings. The LT410 constantly monitors points for leaks, internal faults and power failures and warns of any abnormal conditions. Mounting brackets allow for sensor height adjustment and leveling.

The LT410 is the ideal solution for sensing leaks under a raised computer floor or air conditioning drip pans. Two independent outputs provide added flexibility with the capacity to signal both a local alarm panel and a remote building management system or external equipment, such as motorized water shut-off valves.

The LT410 is also ideally suited for the following:

LIEBERT AIR COOLED VFD CONTROL CONDENSERS  

 STANDARD FEATURES COIL  Liebert manufactured coil is constructed of copper tubes in a staggered tube pattern.  Tubes are expanded in 

continuous, rippled or enhanced aluminum type fins.  The fins have full depth fin collars completely covering the copper tubes which are connected to heavy wall type L headers.  Inlet coil connecter tubes pass through relieved holes in the tube sheet for maximum resistance to piping strain and vibration.  Coil are factory leak tested at a minimum of 300 PSIG, dehydrated, then filled with a nitrogen and refrigerant holding charge and sealed. 

 FAN(S)  Blades are constructed of zinc plated steel or aluminum with a maximum diameter of 30 inches and secured to the 

fan shaft by a heavy duty hub with set screw.  Fan guards are heavy gauge, close meshed, steel wire with corrosion resistant finish.  Fans are factory balanced and tested before shipment. 

 FAN MOTOR(S)   The variable speed fan motor is a specifically designed inverter duty motor with permanently lubricated 

ceramic bearings.  The Liebert variable frequency drive (VFD) control system provides overload protection for the variable speed motor.  Each ambient‐temperature‐controlled fan motor has built in overload protection.  All motors have rain slingers, permanently lubricated bearings and are rigidly mounted on die‐formed galvanized steel supports. 

 HEAD PRESSURE CONTROL   The Liebert VFD Condenser control system is complete with variable frequency drive (VFD), 

inverter duty fan motor operating from 0% to 100% motor RPM based on head pressure, refrigerant pressure transducers , ambient thermostat(s), ambient‐temperature thermostat(s), motor overload protection, and electrical control circuit factory wired in the control panel.   VFD control is always furnished on the fan adjacent to the connection end of the condenser which runs continuously with the compressors.  Other condenser fans are controlled by ambient thermostats and are either “on” or “off”.  This systems allows for operation at ambient conditions as low as ‐20°F (‐28.9°C). 

 HOUSING   The condenser housing is constructed of bright aluminum sheet and divided into individual fan sections by full 

width baffles.  Structural support members, including coil support frame, motor, and drive support, are galvanized steel for strength and corrosion resistance.  Aluminum legs are provided with rigging holes for hoisting the unit into position. 

 TVSS & UNIT DISCONNECT SWITCH   Transient Voltage Surge Suppression and locking disconnect factory installed and wired in 

the enclosed condenser control section.   ALARM CONTACTS   Normally open dry contacts provided for indication of VFD and TVSS alarm condition. 

   OPTIONAL FEATURES FUSIBLE PLUG KIT   Provides compliance for local codes requiring fusible‐plug‐type pressure relief devices.  

Shipped loose for field installation on each liquid line.
