Advanced Training Unit For Fault Location

Product Description

Description of Advanced Training Unit for Fault LocationAdvanced Training Unit for Fault Location is constructed entirely from standard commercial components, including all of the necessary primary and safety controls and will give students valuable experience of system adjustment and fault finding on a multi-evaporator three phase refrigeration system. For student practice up to 25 refrigeration and electrical faults may be introduced into the system.Advanced Training Unit for Fault Location is mounted on a wheeled steel frame with stainless steel base and back panels and incorporates: - A Semi-Hermetic compressor 0.37 kW nominal duty, Air cooled Condenser with aluminium finned, copper coil; two display-case evaporators. Aluminium finned, copper coils with hot gas defrosting; 2 thermostatic expansion valves; a liquid receiver; Low and high-pressure control, thermostatic control, evaporator pressure control, capacity control, condensing pressure control and crankcase pressure control, low pressure switch, high pressure switch.Specification of Advanced Training Unit for Fault LocationThe unit is mounted on a wheeled steel frame with stainless steel base and back panels and incorporates: Compressor: Semi-Hermetic, 0.37 kW. 1450 rpm Condenser: Air-cooled, aluminium finned, copper coil Evaporators: Display-case evaporators. Aluminium finned, copper coils with hot gas defrosting Injection controls: 2 thermostatic expansion valves Liquid receiver Control equipment: Low and high-pressure control, thermostatic control, evaporator pressure control, capacity control, condensing pressure control and crankcase pressure control, low pressure switch, high pressure switch Measuring equipment: Digital temperature indicator with 10 ways elector switch 4 pressure gauges (3 compound,1 high pressure) 2 dial thermometers. Hand-held digital multi-meter Refrigerant: 25 switches located on the side panel under a hinged cover allow combinations of faults to be activated by the instructor. An electrical control box is mounted on the panel and includes accessible three phase relays, fuses and an overload protector. An internal three phase residual current device protects against earth leakage. Fan speed controls and defrost switch with indicator are also panel mounted.
