Refrigeration Laboratory Unit for Science Lab Equipment Laboratory Instruments Manufacturers, Engineering Lab Equipments Manufacturers

Refrigeration Laboratory Unit is a fully instrumented refrigerant vapour compression refrigerator with belt driven compressor, electrically heated evaporator, thermostatic expansion valve and water cooled condenser. Operating parameters can be varied by adjustment of condenser cooling water flow and electrically heated evaporator supply voltage. Components have a low thermal mass resulting in immediate response to control variations and rapid stabilisation. Refrigeration Laboratory Unit Instrumentation includes all relevant temperatures, condenser pressure, evaporator pressure, refrigerant and cooling water flow rates, evaporator and motor power, motor torque and compressor speed.
