Heating Capacity: Up to 12 kW.
Pump Capacity: Up to 3.2 bar or 76 l/min.
Working Temperature Range: -45°C to +250°C.
Temperature Stability: ±0.05°C to ±0.1°C.
Temperature Display: 5.7” TFT Touchscreen.
Refrigerant: R507.
Noise Level: Max 69 dBA at 1 meter distance.
Dimensions: 53 x 66.5 x 126 cm.
Weight: 210 kg.

Features:

Integrated programmer with 8 x 60 steps.
Digital interfaces include RS232, SD Card, USB, Ethernet, Modbus, and Alarm output, with optional RS485 and Profibus.
Single-stage, air-cooled compressor cooling.
Pt100 external sensor connection included.

Electrical Specifications:

Available in multiple voltage versions: 3 x 400V/50Hz, 3 x 230V/50Hz, and 3 x 208-230V/60Hz.
Nominal current varies with voltage, ranging from 13A to 40A.
Plug types include 16A CEE plug, 32A CEE plug, and configurations without a plug.

Additional Information: All data is based on nominal voltage, frequency, and an ambient temperature of +20°C. Cooling capacity is measured at the maximum pump stage, and pump data is based on a bath fluid with a specific density of 1 kg/dm³. Changes may occur without prior notification.
