The A/C System Training System with H-block (EM-2000-YF) is a complete R1234yf air conditioning trainer designed to enhance the instruction of air conditioning physics. This fully operational trainer uses the H-Block TXV design with R1234yf flow control and common automotive components for realistic hands-on training that can be used in both classroom and shop environments. It features a hermetically sealed and internally protected compressor along with clear sight glasses that allow students to observe refrigerant changes of state at the receiver/drier, evaporator, and condenser while providing pressure and temperature measurements exactly as technicians encounter in real-world service.
