Frequently Asked Questions
What refrigerant does the KFON400E4AEA use?
The KFON400E4AEA is approved for R-454A, R-454C and R-455A.
What power supply does the KFON400E4AEA need?
It requires 208/230V 3-phase 60 Hz power, with a minimum circuit ampacity of 29.2 A and maximum overcurrent protection of 45 A.
How much refrigeration capacity does the KFON400E4AEA provide?
It is rated at 34,940 BTU/h at +25°F SST, 90°F ambient, R-454A. Actual capacity depends on box temperature, ambient temperature and line length, so size the system to the calculated box load.
Is the KFON400E4AEA for a walk-in cooler or freezer?
It is an extended medium-temperature unit for walk-in coolers and medium-temperature boxes, with a wider suction temperature range than standard medium-temp units.
What evaporator should I pair with it?
Choose an evaporator rated for the same refrigerant and temperature application with capacity matched to the condensing unit at your design suction temperature. HVAC365 can help match the right evaporator to this unit.
