The Danfoss MT44 is a robust reciprocating compressor engineered for medium and high-temperature refrigeration and air conditioning applications. Here’s a breakdown of its key features:   

Type: Reciprocating compressor   

Refrigerant: Primarily suited for R22 refrigerant. Compatibility with other refrigerants might exist for specific models (consult the manufacturer’s specifications). Important Note: As of January 1, 2020, the production and import of new R22 were banned in many regions, including the United States, under the Montreal Protocol due to its ozone-depleting properties. Servicing existing R22 systems relies on recycled or reclaimed refrigerant, which may become increasingly scarce and expensive.   

Power Supply: Operates on single-phase or three-phase power depending on the specific model variation. Voltage varies by region (e.g., 220-240V/1Ph/50Hz, 208-230V/3Ph/60Hz, or 380-415V/3Ph/50Hz, 460V/3Ph/60Hz). Refer to the manufacturer’s datasheet for confirmation.

Cooling Capacity: Capacity varies depending on operating conditions and the specific model variant. Consult the manufacturer’s datasheet or selection tools for specific capacity information (example: some models around [Insert example capacity range if available, e.g., 45,000 – 50,000 BTU/hr at specific conditions]).

Applications: Primarily used in medium and high-temperature refrigeration and air conditioning systems, including:

• Commercial refrigeration
• Air conditioning units
• Heat pumps (depending on the specific model)
• Process cooling

Given the R22 phase-out, consider the long-term availability and cost of this refrigerant when evaluating systems using the MT44. Newer, more environmentally friendly refrigerants and compatible compressor models are increasingly being used in new installations.
