MKF 250 CFC cooler

- it is designed for circular piping
- the radiator shell is made of galvanized sheet metal
- the condensate drainage pan is aluminium
- the fins are aluminium on copper tubes
- the connection is by a clamp transition with a thread not included in the delivery or by soldering (see table)
- designed for refrigerant R410a
- the maximum working pressure is 40 bar

Installation and operation

- the recommended front air velocity for MKF with integrated droplet eliminator is up to 4 m/s, the evaporator flow area is considered for air velocity calculation, higher speeds should be consulted with the EDV technical department
- installation in horizontal position only
- an air filter must be installed in front of the condenser (protection against contamination)
- it is recommended to place the condenser behind the heater
- when installing the condenser, it is necessary to remember to drain and fill the system and to ensure access for servicing
- in the design, the condenser should be designed to take into account the amount of condensate generated
- the condensate drainage with the odour trap should be checked for the possibility of drying out and to ensure sufficient water column height to overcome the pressure drop of the trap
- to determine the minimum safe level difference in the trap, the following can be used as a guide, by taking the total fan pressure Pt in mm of water column, this value is increased by about 50 % (this value represents a practical recommended value for the height of the water column in the trap so that the odour trap cannot be overcome by overpressure blowing or vacuuming by the fan)
- the passing air must not contain solid, fibrous, sticky or aggressive impurities. It must also be free of chemicals that cause corrosion of the materials used, i.e. corrode aluminium, copper and zinc
- a suitable cooling source may be offered in consultation with the technical department

NOTES

The cooler must be installed in a duct route with airflow in the direction of the arrow on the cooler housing. If the condenser is installed backwards, condensate is not drawn into the condenser and flows out of the condenser. For reliable operation of the condenser, frost protection or power control (defrost cycle) must be provided. The order must specify the requirement for right or left-hand version. The exchangers are manufactured in reversible design.
