CTE

CTE unit cooler
Air flow scheme
Performance ranges
  • Unit coolers capacity: from 1,05 to 57,0 kW *
  • Airflow: from 650 to 28320 m3/h
  • Brine coolers and CO2 coolers: customized on demand
Coil features
  • High heat exchange efficiency
  • Designed with special profile aluminium fins and inner grooved copper tubes

According to the room temperature, the employed fin spacing is the following:

  • CTE H3 for high temperatures (>= +2 °C): 3,5 mm
  • CTE E4 - A4 for high temperatures (>= +2 °C): 4,0 mm 
  • CTE M6 - E6 - A6 for medium temperatures (>= -15 °C): 6,0 mm (electric defrost version ED is recommended)
  • CTE L8 - E8 - A8 for low temperatures (>= -35 °C): 8,5 mm, only equipped with electric defrost (ED)
Standard defrost

Electric (ED) 400V/3/50Hz

Fan guard features
  1. in 250 mm diameter fan motors: manufactured from fibreglass charged polyamide, according to EN 294 standards
  2. in 315, 350 and 500 mm diameter fan motors: manufactured from epoxy-coated steel, according to EN 294 standards 
Air throw The aeraulic combination grants a considerably high air throw, measured in Luvata’s Technical Lab according to CECOMAF GT6-001 standards
Testing Heat exchangers are supplied clean and tested at a pressure of 30 bars 
Miscellaneous Only CTE500 has no fan motors connected

* Nominal capacity: assessed in practical operating ambient, i.e. wet conditions; R404A refrigerant; air inlet temperature = 0 °C; evap. temperature = -8 °C; ΔT = 8 K.
