Science King DLSB-300/80 -80°C Recirculating Chiller (100L Reservoir, 21kW)
Reference: SK-DLSB-300-80
Manufacturer: Science King
- -80 °C to room temperature, ±1 °C
- 100 L reservoir, plate heat exchanger
- Twin hermetic Danfoss compressors, R404A / R23
- 220 / 380 / 460 V 3-phase
A large -80 °C recirculating chiller for industrial extraction and processing. PID control with a touch screen display, a plate heat exchanger instead of a bath coil for higher cooling efficiency, and imported compressors suited to North American voltages.

Options: explosion-proof (EX), -60 °C version, water-cooled condenser, combined chiller and heater.

- PID control system with an accurate digital display; PLC system optional
- Imported compressors (Tecumseh, Danfoss, Panasonic or Bitzer), suited to overseas voltage
- Plate heat exchanger for higher cooling efficiency
