Construction and Design
The Maintenance Kit PolarX - 596 is assembled as a complete, practice-oriented maintenance set for R134A refrigeration systems. The filling station is the central component. It incorporates a vacuum pump for system evacuation and a filling balance for refrigerant charge monitoring, connected via hoses to the refrigeration circuit. The filling cylinder has a 1,000 g capacity. Manometers cover three pressure points: intake pressure (-1 to 10 bar), high side pressure (-1 to 30 bar), and cylinder pressure (-1 to 25 bar). A vacuum meter covers 0 to 1,000 mbar. Two temperature measurement ranges are provided: -60°C to 40°C and -60°C to 85°C.
This maintenance kit includes a battery-operated leak detector for identifying refrigerant leaks without requiring an external power source. A digital multimeter supports electrical measurements and fault-finding during troubleshooting tasks. The hand tool set consists of ring spanners, straight screwdrivers, and Allen keys, covering the fastener types commonly encountered in refrigeration system maintenance. All components in the set are standard refrigeration industry items, ensuring direct relevance to practical field tasks.
Scope of Delivery
Q1: What refrigerant is the Maintenance Kit PolarX - 596 designed for?
The kit is designed for use with refrigerant R134A. All components, including the filling station, filling cylinder, and manometers, are selected and rated for R134A systems.
Q2: What is the capacity of the filling cylinder included in the PolarX - 596?
The filling cylinder has a capacity of 1,000 g. The correct refrigerant charge during filling is monitored using the included filling balance.
Q3: What pressure ranges do the manometers cover?
Three pressure measurements are provided. The low side (intake) manometer covers -1 to 10 bar. The high side manometer covers -1 to 30 bar. The cylinder manometer covers -1 to 25 bar. A vacuum meter covers 0 to 1,000 mbar.
Q4: How does the vacuum pump function in the evacuation process?
The vacuum pump removes air and humidity from the refrigeration system before refrigerant is introduced. Evacuation is a required step before filling to ensure the system is free of non-condensables and moisture.
Q5: What tools and instruments are included in this maintenance kit?
The kit includes a digital multimeter, a battery-operated leak detector, one set of ring spanners, one set of straight screwdrivers, and one set of Allen keys, alongside the filling station with hoses, vacuum pump, filling balance, manometers, and vacuum meter.
