Model of a Refrigeration System with Refrigeration and Freezing Stage | PolarX - 592
Product Overview
The Model of a Refrigeration System with Refrigeration and Freezing Stage PolarX - 592 forms a complete dual-stage refrigeration system when combined with its base unit, sold separately. This Model of a Refrigeration System with Refrigeration and Freezing Stage features two transparent chambers (265x265x265mm each), configurable evaporators in series or parallel, and an adjustable evaporation pressure controller (0~6bar). Expansion options include a thermostatic expansion valve, capillary tube (1.6~2.2m), and bypass valve, with 5 manual service valves for mode configuration. Sensors monitor temperature (6x, -100~400°C) and pressure (2x, -1~15bar), with optional software enabling fault simulation and real-time p-h diagram tracking.

Construction and Design
The Model of a Refrigeration System with Refrigeration and Freezing Stage PolarX - 592 features two distinct refrigeration chambers, each measuring 265x265x265mm with a transparent front. Each chamber includes its own evaporator, fan, and a 150W electric PTC heater to simulate cooling loads. Evaporators can be configured in series or parallel using solenoid valves. One chamber offers a choice between a thermostatic expansion valve and a capillary tube (1.6~2.2m), while the freezing chamber uses a thermostatic expansion valve with a bypass valve. An evaporation pressure controller (0~6bar) allows independent temperature adjustment in the upper chamber during parallel operation. Operating modes are configured using 5 manual service valves, and all components are clearly organized on a panel.
