| Unit Dimensions (W×D×H)/weight | 310 × 410 × 320 mm, Approx. 30 kg |
| Power Supply | AC100V/6A (Need a step-down transformer) |
| (*1)Not equipped with a Temperature control function. Use together with Thermominder, etc. if necessary. | |
| The Min. temp. may not be reached depending on the ambient temperature | |
| (*2)The value under the conditions of ambient temp. 25℃ and liquid temp. 10℃ at 50 Hz. | |
| ●When using a temperature controller, the temp controller that controls the heater is recommended to protect the refrigerator. | |
| ●Use a heater with a capacity larger than the cooling capacity of this product when using together with Thermominder, etc. | |
| ●Use an antifreeze that does not corrode Stainless steel, and is Chemically and Thermally stable with a viscosity of below 30 mm2/s (specific gravity 1.0) within operational temp. range. Our antifreeze (Showbrine Blue) cannot be used at Min. temp. for 250DF. Ask us for details. | |
| ●Do not bend the Cooling pipe too much (Min bending radius is 50 mm for fixed bending). "It may crack and cause gas leakage if bent forcibly. Do not immerse the heat insulation part of the Cooling pipe (the part where the black insulation material is wound) in liquid. | |
| ●Cannot be used with Seawater. | |
