Embraco EMC 3134 U Refrigerator Compressor – R290 Propane, L/MBP, 1/3 HP, 249 W, 7.95 cm³

Embraco EMC 3134 U is a hermetic reciprocating compressor operating with R290 (propane) refrigerant. It belongs to the L/MBP (low and medium back pressure) class: it covers a wide range of applications such as refrigerators, display cabinets, beverage coolers and bottle coolers. It is made in Slovakia.

R290 Propane L/MBP Compressor

R290 is a natural refrigerant with a GWP of 3; it is a future-proof solution compared with the HFC refrigerants restricted by F-gas regulations. Because it delivers the same capacity with a smaller displacement, the compressor is smaller and energy consumption is lower. The EMC 3134 U is designed for capillary tube systems and, with its RSCR motor type, operates in applications requiring low starting torque (LST).

• 🚨 R290 is a flammable gas (A3 class): Installation, charging and service must be carried out by a technician trained in hydrocarbon refrigerants, with spark-free equipment and in a ventilated area. Observe charge limits and room volume rules.
• Electrical components: In R290 systems the relay, overload protector and terminal box must be of the hydrocarbon-compatible (spark-protected) type — standard R134a accessories cannot be used as direct replacements.
• 🔧 LST motor warning: This low starting torque model works only in capillary tube systems (where pressures equalize at shutdown); it cannot start in a system with an expansion valve.
• When replacing the compressor, always renew the filter drier; use R290-compatible POE oil in the system.
