InvoTech YM17–YM50 Small-Capacity Medium-Temperature Scroll Compressors
PRODUCT DESCRIPTION
The InvoTech YM17–YM50 range is a small-capacity, fixed-speed hermetic scroll compressor family developed for medium-temperature commercial refrigeration.
Listed by InvoTech as its new-generation small-capacity range, these compressors combine a compact 139-platform design with application-optimized scroll geometry, dual-compliance technology and a high-efficiency motor.
The range includes E1G three-phase models and E2G single-phase models from 1 to 3 HP. Typical applications include refrigerated cabinets, commercial cold rooms, ice machines and compact refrigeration condensing units.

REFRIGERANT INFORMATION
The official nominal performance table is based on R404A.
InvoTech’s current nomenclature assigns refrigerant code “E” to R404A, R507, R448A, R449A and R452A applications using POE oil. The approved operating envelope and system components must be verified for the selected refrigerant.
