Specifications
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 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)

Air throw
The aeraulic combination grants a considerably high air throw, measured in Modine’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
Notes
* 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.
