What temperature ranges are suitable for an 8HP monoblock unit?

An 8HP monoblock refrigeration unit is typically designed for medium-temperature (MT) and low-temperature (LT) cold room applications. The suitable temperature range depends on compressor type, refrigerant, and system design.

Typical Temperature Ranges

Medium Temperature (MT)

• Room temperature: +10°C to –5°C

• Common setpoints: +2°C to +5°C

• Applications: fresh food storage, fruits & vegetables, dairy, beverages

Low Temperature (LT)

• Room temperature: –10°C to –25°C

• Common setpoints: –18°C to –20°C

• Applications: frozen food, meat, seafood, ice cream storage

Operating (Evaporating) Temperature Reference

• MT systems: –8°C to –2°C evaporating temperature

• LT systems: –32°C to –38°C evaporating temperature

Factors That Affect the Usable Temperature Range

• Refrigerant selection (R134a for MT; R404A/R507A/R448A/R449A for LT)

• Compressor type (scroll vs. semi-hermetic piston)

• Ambient temperature (standard design up to +43°C)

• Cold room insulation quality and load
