Mitsubishi YB645STD Compressor – High‑Efficiency Hermetic Cooling Solution

The Mitsubishi Electric YB645STD is a hermetic, closed‑type cooling compressor with a 645 W (≈2.2 HP) motor. It is engineered for compatibility with modern low‑GWP refrigerants such as R‑410A, R‑32 and R‑290, providing an environmentally friendly solution. Featuring a high efficiency class (SEER 6.5) and low sound level (≈55 dB(A)), the unit minimizes energy consumption while its durable bearings and vibration‑damping mounting plates reduce maintenance costs. YB645STD is widely used in roof‑top package units, multi‑split systems and VRF (Variable Refrigerant Flow) applications. In industrial settings it powers critical cooling for cold storage, wine cellars, food‑processing lines and laboratory refrigeration. Its lightweight, compact design also makes it suitable for mobile and transport‑based cooling solutions. The compressor comes with Mitsubishi’s 10‑year warranty and complies with IEC 60335‑2‑40 and ISO 9001 quality standards. These attributes make the YB645STD an ideal choice for designers seeking high performance, low operating cost and sustainability.
