Non-freon cooling water circulation device NF-300 1 unit

We use the environmentally friendly non-freon refrigerant R1234yf, which has an ozone depletion potential of 0 and a global warming potential of less than 1. Uses stainless steel coil for excellent durability. The liquid contact parts are made of stainless steel, making them highly durable and capable of circulating pure water. It has a powerful cooling capacity and can be used in a wide range of fields. The use of an external temperature sensor allows direct measurement of the object's temperature. Equipped with overload protection device, high pressure switch, safety breaker, and self-diagnosis function. Temperature range (℃): -10 to +30 Temperature control accuracy: ±2.0℃ (room temperature 20℃/maximum circulation amount/power supply AC100V 50/60Hz/setting 5 to 30℃/no load) Circulation method: Closed system circulation Types of liquid used: clean water, pure water, ethylene glycol, etc. External circulation capacity (50/60Hz): Maximum flow rate 12/12L/min, Maximum head 5.4/6.6m (when using pump alone) Cooling capacity (at10): 50Hz/320W Circulation nozzle outer diameter: Φ11mm (suitable tube inner diameter Φ9mm) Liquid tank: φ160×H160mm approx. 3L Refrigerant: R1234yf Size: 218×430×563mm Power supply: AC100V 50/60Hz Timer function: 1 minute to 47 hours 59 minutes (in 1 minute increments) Self-diagnosis function: Upper/lower temperature limit abnormality detection, sensor abnormality, refrigerator overload relay, refrigerator protection timer, power outage detection, control temperature abnormality, memory error External input/output: External temperature sensor input terminal, analog output terminal for thermometer (DC1-5V), alarm output terminal (DC12V-17V) Weight: Approx. 27kg
