AS ONE 4-4565-01 Cooling Water Circulation Device LTC -450 beta

Features

• Uses R448 A, an earth-friendly low-GWP refrigerant. (GWP: 1386) - GWP is approximately 65% lower than LTC-450 alpha (GWP: 3920).
• Compact and slim, it can be installed in many places.
• Made with durable stainless steel coils.
• It uses a new HFC refrigerant with zero ozone depletion potential.
• The wetted part is made of stainless steel, so it has excellent durability and allows pure water to circulate.
• It has strong cooling capacity and can be used in a wide range of fields.
• With the use of an external temperature sensor, the temperature of the object can be measured directly.
• It has an overload protection device, a high-pressure switch, a safety breaker, and a self-diagnostic function.
