5. Presentation - Proper use (Fig. 1)

HP3 units are modular refrigerated systems with air-cooled condensers and propeller fans, consisting
of 3 hermetic or semi-hermetic compressors of various strengths connected to each other and
assembled on a frame. The unit can be supplied with all the elements necessary for proper
performance, including: power and control panel, pressure transducers, pressure switches, and safety
devices.
The combination of various compressor models functioning in diverse ways and with diverse gases,
has allowed us to create a vast array of models that are able to satisfy most needs in terms of
operating power, operating temperature, safety accessories and electronic controllers.
6. Technical Data Page 6
Data is calculated for R404A, condensation temperature +50°C, evaporation temperature -10°C (TN)
and -35°C (BT), overheating 10K. With SCROLL compressors it is possible to further reduce sound
pressure by 10 dB(A), by requesting "SOUND SHELL" soundproofing casing as an option.
Project data
- Maximum Allowable Pressure:
- Maximum Allowable Operating Pressure:Pset =25 bar
- Maximum Permissible Temperature (high pressure):Ts max =+ 63°C Ts min = - 10°C
- Minimum Permissible Temperature (low pressure):Ts max =+ 43°C Ts min = - 35°C
- Coolant types (Group 2 Art. 9 97/23 EC Par. 2.2):R404A - R507A
